What is ISO 4993 - Radiographic testing about?
ISO 4993 is an international standard on steel and iron castings that discusses the test methods for radiographic testing. ISO 4993 specifies the general requirements for the radiography of steel and iron castings by means of X-rays or gamma-rays, in accordance with procedures given in ISO 5579 and ISO 19232.
Who is ISO 4993 - Radiographic testing for?
ISO 4993 on radiographic testing is relevant to:
- Manufacturer of steel and iron castings
- Testing authorities of radiography
- Radiography engineers
Why should you use ISO 4993 - Radiographic testing?
Radiographic Testing (RT) is a non-destructive testing (NDT) method that uses either x-rays or gamma rays to examine the internal structure of manufactured components identifying any flaws or defects.
ISO 4993 provides guidance on general requirements, protection against ionizing radiation, testing parameters, personnel qualifications, testing arrangements, film position plan.
As a user of ISO 4993, you can be ensured of requirements for radiography testing. With obedience and compliance to ISO 4993, you can efficiently perform radiography testing on steel and iron castings by means of X-rays or gamma-rays. ISO 4993 helps you to detect hidden imperfections and defects in steel and iron castings which helps you to improve the quality of steel and iron castings.
