Non-destructive testing of welds - Radiographic testing - Part 1 : X- and gamma-ray techniques with film

This document specifies techniques of radiographic testing of fusion-welded joints in metallic materials using industrial radiographic film techniques with the object of enabling satisfactory and repeatable results. The techniques are based on generally recognized practice and fundamental theory of the subject.It applies to the joints of plates and pipes in metallic materials. Besides its conventional meaning, “pipe” as used in this document covers other cylindrical bodies, such as tubes, penstocks, boiler drums and pressure vessels.This document does not specify acceptance levels for any of the indications found on the radiographs. The ISO 10675 series provides information on acceptance levels for weld evaluation.If contracting parties apply lower test criteria, it is possible that the quality achieved will be significantly lower than when this document is strictly applied.

Non-destructive testing of welds - Radiographic testing - Part 1 : X- and gamma-ray techniques with film

ISO 17636-1:2013 specifies techniques of radiographic examination of fusion welded joints in metallic materials using industrial radiographic film techniques. ISO 17636-1:2013 applies to the joints of plates and pipes. Besides its conventional meaning, "pipe" as used in this International Standard covers other cylindrical bodies such as tubes, penstocks, boiler drums, and pressure vessels. ISO 17636-1:2013 does not specify acceptance levels for any of the indications found on the radiographs. If contracting parties apply lower test criteria, it is possible that the quality achieved is significantly lower than when ISO 17636-1:2013 is strictly applied.

ZOOM ON ... the Requirements department
To comply with a standard, you need to quickly understand its issues in order to determine its impact on your activity.

The Requirements department helps you quickly locate within the normative text:
- mandatory clauses to satisfy,
- non-essential but useful clauses to know, such as permissions and recommendations.

The identification of these types of clauses is based on the document “ISO / IEC Directives, Part 2 - Principles and rules of structure and drafting of ISO documents ”as well as on a constantly enriched list of verbal forms.
