Normenausschussbenennungsnormen des Deutschen Instituts für Normung

Alles begann eines schönes Tages als auf dem Wikipediaartikels des Deutschen Instituts für Normung - kurz DIN, kennt man von Papierformaten, aber die machen Normen für so ziemlich alles.

Wer rausfinden möchte wie das dazu führte, dass ich enorm lange Excel Tabellen in meiner Freizeit erstelle ... bleibt dran >:))

In jenem Wikipediaartikel gibt es eine Liste mit einer Auswahl von Normenausschüssen und dem normierungsbegeisterten Betrachter fällt schnell auf das die nicht alle nach dem selben Muster benannt sind. Einmal heißt es "DIN-Normenstelle Elektrotechnik (NE)", und dann "DIN-Normenausschuss Bauwesen (NABau)" oder "DIN-Normenausschuss Feuerwehrwesen (FNFW)". Die Abkürzungen sind meiner Meinung nach hier das größte Fragezeichen: werden Doppelworte als Gesamtwort (Elektrotechnik -> E) oder nach Teilworten abgekürzt (Feuerwehrwesen -> FW) oder was auch immer bei NABau passiert ist? Ist Normenausschuss kurz N oder NA? Wofür steht überhaupt FN bzw F? (Letzteres hab ich bis heute nicht verstanden, falls es jemandem einleuchtet sagt mir bitte Bescheid 🥲)

Alle diese Abkürzungsregeln sind an sich (fast alle) völlig valide, es ist nur komplett absurd verschiedene Abkürzungsregeln auf der selben Liste zu benutzen und dann auch noch quasi für jeden Ausschuss eine andere Abkürzungsregel! Und das alles nicht von Irgendwem sondern vom DIN selbst, die machen ja nichts anderes als zu normen! Mir kann da keiner erzählen, dass das keine Absicht ist. Ich bin überzeugt, dass die beim DIN einfach extrem lustig sind und sich absichtlicht neue Abkürzungen für ihre Normenausschüsse ausdenken und ich bin großer Fan.

Deswegen wollte ich dann genau wissen wie viele verschiedene Abkürzungsregeln - bzw Normenausschussbenennungsnormen könnte man auch sagen - es auf der Liste gibt. Ich habe also den einzig logischen Schritt gemacht und mit auf der Seite des DIN eine Liste mit deren Normenausschlüssen heruntergeladen und in Excel abgetippt :)

[Bildbeschreibung: 2 Bildschirmfotos von der unfertigen Tabelle. Naben der Liste der Ausschüsse sind vielle wirre Notizen zu Unterscheidungen. /Ende BB]

Bei der Liste fällt direkt auf, dass alle Normenausschlüsse eine Kennnummer haben und deswegen nicht auf ihren Namen zur Identifizierung Verlass haben müssen. Ich hab dann versucht jede vorkommende Art der Benennung und Abkürzung zu identifizieren und habe dazu einen Klassifikationsschlüssel vergeben. Der hat für mich Sinn ergeben, aber ich glaube er ist evtl. ein bisschen überkompliziert also erklär ich einfach die Ergebnisse. Hier ist die fertige Klassifizierung:

[Bildbeschreibungen: Die vollständige Tabelle der Normenausschüsse und Klassifizierung. Auswertung folgt im Text. /Ende BB]

Die insgesamt 69 Normenausschüsse werden auf 30 verschiedene Arten abgekürzt!! *Klatschen und Beifallrufe*

alph# ist die Laufnummer für alphabetische Sortierung nach Fachbereich, so wie sie aus der offiziellen Liste entnommen wurde.

NA # ist die offizielle Kennnummer des Ausschusses. Ich gehe davon aus die werden bei Entstehung vergeben und würden demnach eine zeitliche Sortierung ergeben. Die Nummern sind sehr viel größer als 69, da sich Kennnummern nicht doppeln oder ändern dürfen, vermutlich sind viele Nummern an NAs vergeben, die ist inzwischen nicht mehr gibt. Ist aber alles nur Mutmaßung, ich weiß nicht mit Sicherheit wo die Zahlen herkommen.

Normenausschluss (NA) ist der volle Name der NAs in Worten.

Abkürzung ist jeweils die offizielle Abkürzung.

Der Rest ist mein Klassifizierungsschlüssel, der darstellen sehr wie sehr die Bennenung von der Norm abweicht. A# ist die Abkürzungsnummer, die ich als Laufnummer für jeden möglichen Schlüssel vergeben hat. Wenn ich sage es gibt 30 verschiedene Abkürzungsregel gibt es also A#0 bis A#29 die jeweils für eine bestimmt Abkürzungsregel steht.

WICHTIG: Norm bzw normal ist in diesem Kontext immer darüber definiert wie häufig die Abkürzungsregel in der Liste vorkommt. 0 steht immer für die am häufigsten Vorkommende Art, 1 bis 3 sind Varianten mit zunehmender Obskurität, und ? ist in der Regel einzigartig.

Es gibt drei Teile, die hier unabhängig voneinander bewertet werden: "Name" bezieht sich auf den Namen in Worten. 0 wird vegeben für NAs, die nach dem Muster "DIN-Normenausschuss [Fachbereich]" benannt sind und bildet 92,8% der Liste (64/69). 1 steht für "DIN/VDI-Normenauschluss [Fachbereich]" und kommt einmal vor, 2 steht für "DIN-Normenstelle [Fachbereich]" und kommt zweimal vor. ? wurde ebenfalls zweimal vergeben für "VDI/DIN-Kommission Reinhaltung der Luft (KRdL) - Normenausschuss" und "DKE Deutsche Kommission Elektrotechnik Elektronik Informationstechnik in DIN und VDE". Hält sich noch in Grenzen mit der Obskurität, man kann sich auch noch vorstellen warum es hier Abweichungen gibt.

Kürzel1 kürzt den "Normenausschuss/-stelle" Teil ab und hat 4 häufige Varianten: 0(0)/"NA" in 31/69 also 44,9%, 0(1)/"N" in 21/69 also 30,4%, 1(0)/"FN" in 9/69 also 13,0% und 1(1)"F" in 4/69 also 5,8%. Die restlichen 4 sind einzigartig. Ich weiß wie gesagt nicht wofür das F steht :(

[Bildbeschreibung: 3 Kreisdiagramme die die Anteile der Varianten in jeweils "Name", "Kürzel1" und "Kürzel2" zeigen. Auswertung im Text. /Ende BB]

Bei Kürzel2 wirds kreativ! Hier wird der Fachbereich abgekürzt.

0 ist mit 43,5% (bzw 30/69) die Abkürzung mit dem ersten Buchstaben aller großgeschreibenen Worte. Bsp: "Maschienenbau" -> M, "Eisen-, Blech- und Metallwaren" -> EBM, "Kommunale Technik" -> KT

1 (14,5%, 10/69) ist wie 0, aber mit den ersten Buchstaben der Teilworte. Bsp: "Materialprüfung" -> MP, "Wälz- und Gleitlager" -> WGL

2 (11,6%, 8/69) ist wie 0, aber unvollständig. Hier ist fast immer nur das erste Wort benutzt ("Luft- und Raumfahrt" -> L), außer bei "Federn, Stanzteile und Blechformteile" -> FS. Wenn ich pingelig wäre könnte man hier noch ne Extrakategorie aufmachen ...

3 steht dafür wenn mehr als der erste Buchstabe vorkommt. Hier werden auch Kleinbuchstaben verwendet. Unterkategorien sind:

3(0) (7,2%, 5/69) heißt die ersten drei Buchstaben: "Ergonomie" -> Erg

3(1) (2,9%, 2/69) ist wie 3(0) aber mit einem Buchstaben mehr oder weniger als drei: "Tankanlagen" -> Tank und "Kältetechnik" -> Kä. (Auch hier könnte noch eine Pingeligskeitkategorie entstehen)

3(2) (4,3%, 3/69) ist 2 Buchstaben, aber ... nicht korrekt abgekürzt. Damit meine ich, dass ich oben in die 2 gesteckt hätte. Bsp: "Papier, Pappe und Faserstoff" -> Pa. (Wenn man "falsch" als unzugenügende Kategorisierung betrachtet sind hier nochmal +2 Pingeligkeitskategorien, da dann alle einzigartig sind)

3(?) (4,3%, 3/69) sind eindeutig einzigartig. "Sport- und Freizeitgeräte" -> Sport und "Dental" -> DENT

? hat diesesmal auch Unterkategorien! Nur ?(1) ist einzigartig, denn ?(0) wurde für etwas vergeben, dass es genau zweimal gibt: Abkürzung mit dem ersten Buchstaben inklusive kleingeschriebender Worte: "Kommission Reinhaltung der Luft" -> KRdL und "Feinmechanik und Optik" -> FuO. Also nicht einzigartig, sondern nur eigenartig :o)

Alles mit ?(1) (8,7%, 6/69) gibt es aber nur einmal! Hierunter sind viele meiner Favoriten: "Erdöl- und Erdgasgewinnung" -> ÖG (ergibt NÖG. macht Spaß zu sagen.), "Stahldraht und Stahldrahterzeugnisse" -> D, "Textil und Textilmaschinen" -> Textil, "Automobiltechnik" -> Automobil, und nun mein Albtraum in der Kategorisierung: "Grundlagen der Normungsarbeit" -> GLN und "Grundlagen des Umweltschutzes" -> GUS. Beides zwei Doppelwörter wovon eines als Gesamtwort und eines nach Teilworten abgekürzt sind. Aber trotzdem weigere ich ich die in die selbe Kategorie zupacken, weil sie sich so dreist die Mühe machen es doch jeweils anders zu machen obwohl sie beide mit "Grundlagen" anfangen.

So.

Meine persönlichen Lieblinge der Absurdität sind "DIN-Normenausschuss Textil und Textilmaschinen" -> Textilnorm, "DIN-Normenausschuss Gießereiwesen" -> GINA und "DIN-Normenausschuss Verpackungswesen" -> NAVp. Erklär mir bitte einer nach welcher Logik man Verpackungswesen zu Vp abkürzt. Und natürlich "DIN-Normenausschuss Grundlagen der Normungsarbeit" -> NAGLN ... der Normungsnormennormungsausschuss <3

Aber die eigentliche Norm wäre ja "DIN-Normenauschuss [Fachbereich]" -> NA + erster Buchstabe aller großgeschreibenen Worte, richtig? Ne.

Bei Kürzel1 und Kürzel2 ist die 0 nicht der Großteil also unter 50% der NAs, so viel also zur "Norm". Aber tatsächlich ist A#0 also [0; 0(0); 0] nicht nur unter 50%, sondern mit 14,5% noch nicht mal die häufigste Variante. Das ist A#11 - [0; 0(1); 0] mit 15,9% (wobei Kürzel1=0(1) ja nicht häufiger als Kürzel1=0(0) ist). Also kann man sich jetzt streiten ob die wahre Häufigkeitsnorm nicht doch "DIN-Normenauschuss [Fachbereich]" -> N + erster Buchstabe aller großgeschreibenen Worte ist.

Jedenfalls kommt mit 20 einzigartigen Abkürzungsregeln nur ein Drittel überhaupt mehr als einmal vor.

[Bildbeschreibung: Tabelle mit allen Abkürzungsnummern und zugehörigen Schlüsseln, Häufigkeit und Prozenten. Auswertung ging vorraus. /Ende BB]

Und was für einen Schluss kann man jetzt aus der ganzen Sache ziehen? ... Äh. Ääääähm. Also ich hatte Spaß :)

The company, a leading provider of JIS Flanges, is constantly broadening its range of services to meet the evolving needs of its varied customers.

Flanges are critical components across many industrial sectors because they bridge most of the equipment related to piping, valves, pumps, and others. Their importance range across application-including oil and gas, chemical processing to power generation, water treatment, and construction industries.

The Role of Flanges in Manufacturing :  Metalica Forging Inc

Before discussing impact from standards, a brief description of what a flange is and how important of a tool it has been in mechanical construction is necessary. A flange is a mechanical element allowing pipes, valves, along with other machinery parts to make connections. The greatest advantage of flanges lies in the flexibility in assembling and disassembling for repair, maintenance, and inspection purposes. They are usually bolted and have gaskets placed between flanges in order to ensure a tight seal that is leak-tight.

The Need for Flange Standards

Global manufacturing involves a global process in which various industries rely on products and equipment from other regions. Standardization in the design of flange, production, and application is achieved because a slight difference in measurements or material quality of flanges would lead to devastating outcomes. The goal of the flange standards is making parts from different manufacturers substitutional so that systems work with fewer limitations.

Key Flange Standards in Global Manufacturing

Several organizations have established flange standards that are recognized and used globally. The most widely adopted flange standards include:

ANSI/ASME B16.5: This American standard covers the pipe flanges and flanged fittings, which specify the pressure ratings and material requirements for flanges from size ½ inch to 24 inches. These ANSI/ASME B16.5 flanges have gained immense popularity in several industries worldwide, especially in North America.

DIN (Deutsches Institut für Normung): The DIN standards, established in Germany, are widely used in European countries. DIN flanges have their specific dimensions and pressure ratings, and they play a significant role in European manufacturing sectors.

EN (European Norms): EN standards are developed by the European Committee for Standardization. They harmonize flange dimensions and material requirements across Europe, facilitating trade and ensuring consistency within the European Union and other regions.

ISO (International Organization for Standardization): ISO standards provide a framework for harmonizing flange standards globally. ISO standards are essential for companies looking to operate internationally and ensure that their products comply with regulations in different countries.

Impact of Flange Standards on Global Manufacturing

1. Interoperability and Supply Chain Efficiency

Flange standards are important to the interoperability of parts bought from different parts of the globe. Because of globalization of supply, companies must source raw materials, equipment, and parts in several countries. For example, if a domestic manufacturer sources its piping from Europe and its valves from Japan, the standardized flanges ensure that they fit together, thus minimizing the waste of unnecessary idle time and costly delays.

2. Facilitating International Trade

Flange standards are crucial in facilitating international trade, as they eliminate technical barriers among the countries. Components manufactured without standard guidelines would require customized products to meet the varied requirements of each country or region, thus involving a lot of time and cost. International recognition ensures that companies selling their products to multiple markets do not necessarily need significant modifications to the product, ultimately making business easier.

3. Enhancing Safety and Reliability

Oil and gas as well as chemical processing and power generation are some of the industries where safety is of prime importance through the flanges used in containing fluids under high pressure or corrosive chemicals. Default in the flange standards can lead to leaks and failure of equipment, even accidents catastrophic in nature. Flange standards ensure that materials chosen can withstand pressure and temperature requirements to avoid dangerous situations.

4. Innovation and Technological Advancement

Flange standards help ensure consistency and compatibility, but they also enable innovation. Manufacturers can create new materials, coating techniques, and production processes that meet existing standards while providing better performance, durability, or cost-effectiveness. Advancements in metallurgy have led to the development of corrosion-resistant alloys, which are now commonly used in flange production, improving the longevity and performance of flanged connections in challenging environments.

Shadows of Integrity: Architecture as a Living Document of Memory and Time

In the architecture of history, the document controller becomes a custodian of both the physical and philosophical dimensions of design, embodying a role that resonates with the heritage of luminaries like Daniel Libeskind. Libeskind’s assertion that architecture is the “biggest unwritten document of history” reflects his broader legacy, rooted in memory and identity. His works, such as the Jewish Museum Berlin, navigate the relationship between form, shadow, and historical narrative, where space becomes an envelope for collective memory.

Similarly, the DIN (Deutsches Institut für Normung) format, originally a German standard, has become a global framework that structures not just architectural drawings but the way we communicate and preserve the technical language of architecture. It reflects the precision and universality that architecture demands, creating an international order that sustains the integrity of designs across time and space.

Folding, envelopes, and shadows are not merely design elements but metaphors for how architecture engages with time. The envelope, in this context, holds not just the physical space but the intangible—shadows that represent the invisible forces at play in architecture: memory, culture, and historical weight. The shadow, in its fleeting nature, offers a counterpoint to the permanence of built forms, much like the document controller’s role in preserving architectural truth against the ravages of time.

This abstract honorus the versatile architect who, like Libeskind, navigates the tensions between time and memory, form and shadow, and the document controller who ensures that the architectural narrative remains honest. In doing so, they protect the sanctity of architecture as a living record—one where shadows and folds are not erasures but layers that enrich our understanding of history and its projection into the future. The architect’s war with time is ultimately a battle for the integrity of this unwritten document, where every preserved drawing, every shadow cast, becomes part of a larger architectural legacy that speaks to our shared heritage and future.

#1101 Why do we use A4 as a paper size?

Why do we use A4 as a paper size? We use A4 because it is a ratio of A0, which is 1 square meter of paper. The A system of paper was invented in Germany and adopted by almost all of the countries in the world in 1975. The only countries that don’t use it as the official document size for most government functions are the USA and Canada.  Paper has existed since it was invented in China in roughly 100 AD. The invention is attributed to a court official called Cai Lun, but fragments of paper that predate him have been discovered, so it must have been invented earlier. Before the invention of paper, most countries use papyrus, vellum, parchment, or other types of surface. China was the first country to make a paper from the fibers of plants. They soaked and pounded rags and plants until they could take the mat of fibers and dry them, producing rudimentary paper. Paper was a world changing invention and slowly spread around the world. There were gradual improvements in how it was made but there were no official sizes. Paper was cut as big or as small as the person buying it needed. Books were written by hand so there was no need to have a standard paper size that could fit into a machine, as we do today. Old books, like old bibles, tend to be a variety of sizes. When the printing press was invented, it did standardize paper in some ways, but not others. A printer was likely to print all of one print run of books on paper that was roughly the same size, but different printers might use different sized paper. As printing became more common and mass-produced paper became possible, the price of books dropped and more people learned to read. Once this happened, books were generally printed on similar sized paper, but it was still not exactly the same. The first person to come up with the idea for standardized paper was a German physicist called Georg Lichtenberg in 1786. He never introduced the system, but he came up with the idea for it. He proposed that paper should be sized on an aspect ratio of the square root of 2. The easiest way to think about this is that each size of paper can be cut into two pieces of the next size down. For example, A3 can be perfectly cut into two pieces of A4. Lichtenberg wrote this idea in an essay, but it was never published during his lifetime. He wrote many essays and kept numerous notebooks that he called scrapbooks. These were all published after his death by his sons. The idea for standardizing paper was taken up again by a German engineer and mathematician called Walter Porstmann and a Nobel prize winning chemist called Wilhelm Ostwald in 1922. Portsmann worked for the Standards Committee of German Industry, which became the German Institute of Standardization. One of the things Porstmann was involved with was the standardization of paper sizes. The system he came up with was called the DIN system. DIN stands for Deutsches Institut für Normung, which means “German Institute of Standardization”. The DIN system was simple and it was metric. It caught on and over the next fifty years it gradually spread around the world, becoming the accepted size of paper. In 1975, the International Organization for Standardization decide that the German system would be the International system and they renamed it ISO. (Incidentally, ISO doesn’t stand for International Organization for Standardization. It is taken from the Greek word isos, which means equal.) So, how does the ISO paper system work? Well, there are 3 different systems that use a different starting size, but then they all progress the same way. They all go back to the original idea thought up by Lichtenberg. The A series came first. A0 is the first one and it is a rectangle with an area of 1m2. It has a width of 841 mm and a height of 1189 mm. The next size is A1, which is half the width of AO. 2 A1 papers will fit side by side inside the A0 area. The width of A1 is 594 mm, but the length is 841 mm. The length of each subsequent size is the width of the previous size. This continues all the way down to A10, which is the smallest. If you tried and were very patient, you could fit 2048 A10 pages in the area of one A0 page. The same works for the B sizes and the C sizes, although they start with a different area. The size of B0 is 1.414 m2 and the size of C0 is 1.189 m2. The same properties apply, though, because the width of the previous size is always the length of the next size and you can always fit two of the next size in the area of the previous size. This makes it very easy to scale and very simple to use. And this is what I learned today.

What are Flanges?

Flanges are mechanical devices used to connect pipes, valves, pumps, and other equipment to form a piping system. They are typically bolted together and sealed with a gasket to ensure a leak-proof joint. Flanges come in various types, such as weld neck, slip-on, socket weld, lap joint, and threaded, each serving different purposes and application scenarios.

ANSI and ASME: The Foundations

ANSI (American National Standards Institute)

The American National Standards Institute (ANSI) oversees the development of voluntary consensus standards for products, services, processes, systems, and personnel in the United States. ANSI does not develop standards itself but accredits organizations that do. For flanges, ANSI’s involvement is mainly in the form of endorsing standards developed by other organizations, such as ASME.

ASME (American Society of Mechanical Engineers)

The American Society of Mechanical Engineers (ASME) is a professional organization that develops and publishes standards across a wide range of engineering disciplines, including pressure vessels, piping, and flanges. ASME standards are widely recognized and used around the world.

ASME B16.5

One of the most critical standards for flanges is ASME B16.5. This standard covers pipe flanges and flanged fittings for sizes ranging from ½ inch to 24 inches. It specifies dimensions, materials, pressure-temperature ratings, tolerances, marking, and testing requirements. ASME B16.5 flanges are classified based on their pressure rating, which ranges from 150 to 2500, indicating the maximum pressure (in psi) they can handle at a specified temperature.

ASME B16.47

For larger flanges, ASME B16.47 comes into play. This standard covers flanges for sizes from 26 inches to 60 inches. It is divided into two series: Series A (formerly MSS SP-44) and Series B (formerly API 605), each with different dimensions and pressure ratings. Series A flanges have thicker and heavier construction compared to Series B, providing higher strength and rigidity.

Most Trusted Manufacturer leading flanges in several Indian cities:

MS Flanges Manufacturer In Rajkot

MS Flanges Manufacturer In Ahmedabad

MS Flange Manufacturer In Surat

MS Flange Manufacturer In Pune

MS Flange Manufacturer in Bhavnagar

Beyond ANSI and ASME: Other International Standards

While ANSI and ASME standards are prevalent in North America, other parts of the world follow different standards. Some of the most significant ones include:

DIN (Deutsches Institut für Normung)

DIN standards are widely used in Germany and Europe. DIN 2633, for example, specifies welding neck flanges, covering dimensions, tolerances, and material specifications. DIN flanges are known for their precision and robustness, making them suitable for high-pressure and high-temperature applications.

EN (European Norm)

The European Norm (EN) is a standard that applies across the European Union. EN 1092-1 is the most commonly referenced standard for flanges in Europe, covering dimensions, pressure ratings, materials, and testing requirements. It includes different types of flanges such as plate, loose, welding neck, and threaded flanges.

JIS (Japanese Industrial Standards)

Japanese Industrial Standards (JIS) are used in Japan and other parts of Asia. JIS B 2220 is the standard for steel pipe flanges, specifying dimensions, materials, pressure ratings, and testing requirements. JIS standards are known for their high quality and reliability.

GOST (Gosudarstvennyy Standart)

GOST standards are used in Russia and other countries of the former Soviet Union. GOST 12820-80 is the standard for flat flanges, covering dimensions, tolerances, and material specifications. GOST flanges are designed to withstand extreme conditions, making them suitable for applications in harsh environments.

Key Considerations for Selecting Flanges

When selecting flanges for a piping system, it is essential to consider several factors to ensure compatibility and performance:

Pressure Rating: Ensure the flange can handle the maximum pressure of the system.

Material: Choose a material that is compatible with the fluid being transported and the operating conditions.

Temperature: Verify that the flange can withstand the operating temperature range.

Size and Dimensions: Ensure the flange matches the pipe size and meets the required dimensions.

Standards Compliance: Confirm that the flange complies with the relevant standards for the region and application.
