Which of the following standards is NOT associated with Liquid Penetrant Testing?

ISO 9001 is primarily focused on quality management systems and does not specifically address the processes or techniques related to Liquid Penetrant Testing (PT). It provides a framework for organizations to ensure they meet customer and regulatory requirements while enhancing customer satisfaction.

In contrast, the other standards mentioned are directly related to Liquid Penetrant Testing. ASTM E165 is a standard guide for Liquid Penetrant Testing, detailing the procedures and acceptance criteria. ASME BPVC (American Society of Mechanical Engineers Boiler and Pressure Vessel Code) encompasses codes that might involve liquid penetrant testing as part of the requirements for ensuring the integrity of welded components. ISO 9712 specifically addresses the qualification and certification of NDT personnel, including those performing liquid penetrant testing.

Thus, the distinction is clear: ISO 9001 does not pertain to the technical aspects of Liquid Penetrant Testing, which is why it stands out as not being associated with this method.
