NDT Codes and Standards 5

Question 1

What is the significance of the 'referencing code' in ASME Section V?

Accepted Answer

It specifies which Section V articles apply and may impose additional or modified requirements

Answer

The referencing code (e.g., Section I, III, VIII) invokes and may modify Section V requirements, so both documents must be consulted together.

Question 2

Which organization issues the EN ISO 9712 standard used internationally for NDT personnel qualification?

Accepted Answer

ISO/CEN

Answer

EN ISO 9712 is published jointly by the International Organization for Standardization (ISO) and the European Committee for Standardization (CEN).

Question 3

In ASME B31.3 Process Piping, what is the required volumetric examination percentage for normal fluid service welds?

Accepted Answer

10%

Answer

ASME B31.3 requires 5% random radiographic or ultrasonic examination of welds in normal fluid service as the base examination requirement.

Question 4

What does the AWS D1.1 'prequalified joint' designation mean for NDT purposes?

Accepted Answer

The joint design has pre-established welding parameters that may reduce the required procedure qualification testing

Answer

A prequalified joint in AWS D1.1 meets established dimensional and design criteria that allow the use of prequalified WPS parameters without procedure qualification testing, but NDT requirements still apply.

Question 5

According to ASME Section V Article 6, what is the purpose of a 'PT System' qualification?

Accepted Answer

To demonstrate that the combination of penetrant, cleaner, and developer materials perform adequately together

Answer

PT system qualification ensures that the specific combination of penetrant materials (penetrant, cleaner, developer) meets the minimum performance requirements as a system.
