In Liquid Penetrant testing, who must agree on testing procedures?

In Liquid Penetrant testing, it is essential for the company and the nondestructive testing (NDT) contractor to agree on the testing procedures because both parties have vested interests in ensuring that the methods employed are suitable for the specific materials and conditions present. The company typically has its quality assurance standards and may have specific requirements for the testing process, while the NDT contractor brings expertise about the testing methods and practical implementation.

This agreement helps to establish a mutual understanding of the testing protocols, ensuring that the tests are conducted effectively and meet the quality assurance standards imposed by the company. This collaborative approach not only aligns expectations but also reinforces compliance with applicable standards and regulations, leading to more reliable results in the assessment of the integrity of pipelines and related facilities.
