The Potential Of Ultrasonic And Eddy Current Testing For Wind Turbines

Wind turbines are a rising resource of renewable energy with countries across the world turning more concerned regarding energy utilisation. Financiers, project stakeholders and energy regulators need confidence that they can depend on a wind turbine before utilising it in their project.  There are several areas of wind turbines that need routine checkups, for instance, inspecting the gear teeth and bearings, or identifying defects and corrosion. NDT or nondestructive testing gives experts the capacity to discover inconsistencies despite not having to use damaging testing measures.

Ultrasonic Tests

Ultrasonic NDT tests are frequently leveraged to examine blades of wind turbines.

Adaptable inspection methods are particularly applicable to wind turbines, because the blade geometries as well as further elements of the turbines comprise uneven geometries and surfaces. Primarily, blades usually have thick attenuation and are made up of compound materials, which is why testing becomes a challenge. Materials that may be present within a turbine blade include:

Typical materials that are found within a turbine blade:

Steel

Iron

Resin

Aluminium

Fibreglass

Turbine blades tend to endure intense stress while functioning and furthermore they also come with inbuilt flaws during manufacture. These flaws can be difficult to detect when you don’t have the proper equipment. Nevertheless, phased array ultrasound is exclusively created to detect and analyse minor flaws minutely.

What's more, advanced ultrasonic systems involve forceful pulses designed to pierce through heavy weld materials, probing into concealed issues that would have kept being unnoticed.

 Eddy Current Test

This NDT testing is a viable alternative that is becoming more and more popular for testing wind turbines. Eddy Current Test equipment can identify anomalies on a near-surface and surface level. In the same way as ultrasonic tests, ECT superior in comparison to other NDT tests because it does not call for the use of harmful chemicals or a continual source of electricity. Sophisticated ECT equipment is easily transportable (certain compact instruments can even be held by analysts) and offer single-pass probe features that enable analysts to meticulously cover a big testing area without investing too much time.

Also, just as specific UT techniques provide advantages that typical ultrasonic testing do not offer, likewise specific ECT methods have advantages over conventional eddy current systems. That is why eddy current array (ECA) is being leveraged these days, as it delivers a highly in-depth level of inspection of irregular and flat surfaces. This system supports surface array probes designed to examine welds made up of a range of material types and geometries. Using an ECA probe, analysts can identify cracking and corrosion easily.

Wind turbine manufacturers have to show their turbines work as required under all conditions. NDT tests like Eddy Current testing and ultrasonic testing have proven to be efficient and effective methods to make sure your turbines comply with all pertinent international standards. Testing consultants will guide you through the whole process, ensuring that you gauge your turbine’s performance and challenges.

The Need For Biocompatibility Testing For Medical Devices

In terms of medical devices, biocompatibility indicates the interplay between the physiological systems and tissues of patients and the medical device in question. Most medical devices involve physical contact with patients either indirectly or directly. There is potential for this contact to have unwelcome and/or unwarranted side effects. In order to eliminate any negative consequences and ensure that patients are sufficiently protected, manufacturers need to test medical devices and their components for biocompatibility. The test will assess and measure the risk to the patients. Biocompatibility hinges on various considerations:

the different patient tissue that the device will be exposed to

the length of the exposure

the physical nature and chemical aspects of its component materials

Basically, the key purpose of a biocompatibility assessment of medical devices is to safeguard patient safety. Additionally, manufacturers would need to take corporate compliance risks and regulatory goals while opting for biocompatibility testing services.

The Data That’s Needed

Manufacturers could lessen the volume of testing required for their medical device in case they have of biocompatibility data of the following types-

Data from previous submissions

Data from suppliers of materials or components

Analytical data

Clinical data

Identifying the Tests Needed 

Designers of the medical device would have to typically confer with a skilled toxicologist to outline the best way to cater to the materials requirements of the biocompatibility testing matrix. In terms of every biological effect type, the basis for the testing strategy needs to be recorded. This is particularly necessary in case a manufacturer makes the decision to opt out of carry out tests for an effect mentioned by their device category matrix.

At its centre, the ISO Standard requires verification of the capacity of the device to perform the proposed use. The primary task in the procedure is chemical classification of device components.

Biocompatibility testing of medical devices involves the critical stage of biological testing. A classification of devices is done in the biocompatibility testing matrix according to the duration and type of body contact. The matrix lists all possible biological effects. For every type of device, certain effects need to be checked and put forward in that device’s regulatory submission. ISO 10993-1 does not impose a particular series of tests for each type of medical device.

Manufacturers must collect safety data on all material and components that make up the device. Moreover, they would have to opt for testing services to evaluate the finished product in accordance with ISO 10993-1. In case an unfavourable outcome is found, it can be challenging to trace the component that is engendering the issue. This could lead to delays in submitting regulatory compliance as they attempt to repeat testing on the separate components.
