Which QA form is designated for recording ultrasonic inspections?

The correct answer is QA Form 18A, which is specifically designated for recording ultrasonic inspections. Ultrasonic testing (UT) is a non-destructive testing method used to detect flaws in materials by using high-frequency sound waves. The use of a specific form, such as QA Form 18A, helps ensure that all relevant data, including the conditions of the inspection, the equipment used, and the results of the tests, are systematically documented. This enables consistency in reporting and facilitates review and analysis later, providing a clear and organized record of inspections that can support quality assurance practices.

The other forms listed are used for different types of inspections or data documentation and are not specific to ultrasonic testing. Each QA form has a designated purpose, which allows QA professionals to maintain clarity and organization in the documentation process. Thus, using the correct form for its intended purpose is crucial in quality assurance practices to maintain compliance and uphold standards.
