These agencies have the power to enforce standards and certifications across different industries. This means they check if companies are doing their testing right, using methods like UT, RT, or PT correctly.

They focus on public safety and quality control – important stuff when we’re talking about things like boilers, pipelines, or buildings that need to be strong and safe for people to use.

Agencies look at how tests are done and make sure workers are trained right. If something’s not up to scratch, they can step in. So basically, these bodies help guarantee that when an engineer says something’s good to go – it really is safe and built well according to global benchmarks like those set by ASME or ISO.

In this setup, organisations get guidance on best practices from ASTM International or the American Welding Society (AWS), but it’s the regulatory guys who ensure these guidelines turn into action on ground level – influencing everything from small workshops to big factories around the globe.

Their stamp of approval matters because it tells customers that products meet high international standards for quality management systems such as ISO 9001:2015.

Differences Between Codes, Standards, and Specifications

Codes tell us the rules we must follow, making sure things are safe and right. They’re like the laws in NDT (nondestructive testing) that say how to test things without breaking them.

It’s all about keeping everyone safe while checking stuff works as it should. Standards, on the other hand, are more like helpful hints. They guide us on doing NDT the best way possible, using methods that have worked well before.

This helps make sure everything is top quality and consistent no matter where you are or what you’re working on.

Specifications get really specific — they outline exactly what needs to be done or what features something must have. Think of it as a shopping list for materials or a recipe for a service; everything has to match up just right or it won’t work properly.

So, every time we use ultrasonic testing (UT), radiographic testing (RT), or any type of NDT method, specifications ensure we know exactly what’s needed down to the very last detail..

Now let’s dive into how these important codes and standards come into being.
