What is BS EN ISO 17636-1 - Non-destructive testing of welds about?

Non-destructive testing (NDT) is a technique used by industry to evaluate a material, component, structure, or system for differences or defects, without causing damage to the original part. NDT techniques include magnetic particle testing, penetrant testing, ultrasonic testing and radiographic testing. BS EN ISO 17636-1 is an international standard that describes radiographic testing of welds using X- and gamma-ray techniques with film.

Who is BS EN ISO 17636-1 - Non-destructive testing of welds for?

Within the oil and gas, rail, manufacturing and nuclear industries it will be used by:

• NDT site managers
• Specialist inspectors
• Technologists
• Project managers
• NDT experts
• Research and development engineers
• Quality engineers

What does BS EN ISO 17636-1 - Non-destructive testing of welds cover?

BS EN ISO 17636-1 specifies techniques of radiographic examination of fusion welded joints in metallic materials using industrial radiographic film techniques.

BS EN ISO 17636-1 applies to the joints of plates and pipes. Besides its conventional meaning, “pipe” as used in this document covers other cylindrical bodies such as tubes, penstocks, boiler drums and pressure vessels.

Why should you use BS EN ISO 17636-1 - Non-destructive testing of welds?

• To enable satisfactory and repeatable results consistently and economically
• To develop expertise
• To improve efficiency
