Scope

GB/T 19943-2026 is the English-translated version of 无损检测金属材料X或伽马射线胶片照相检测基本规则.

Radiographic testing with film is still widely used to examine castings, welds and other metallic components, and this standard lays down the basic rules for testing metallic materials with film using X-rays or gamma rays. As the title indicates, it concerns general principles that apply across applications rather than a single product type. It belongs to the non-destructive testing group and is a recommended national standard.

Radiographic testing companies, certified inspectors, quality managers at foundries and fabricators, and procedure writers for pressure equipment and structural work are the natural users. Auditors and customers who review radiographic procedures may also consult it.

The edition was issued on 30 July 2026 and takes effect on 1 February 2027, replacing GB/T 19943-2005. Procedures written to the earlier edition may need to be reviewed in light of the new one.
