NDE standards
There are many standards dealing with all methods of NDE
but it is worth being familiar with the following:
. EN 970: Non-destructive Examination of Fusion Welds –
Visual Examination
This European standard covers the visual examination of
fusion welds in metallic materials. It is normally, but not
always, performed on welds in the as-welded condition.
. EN 1206: Non-destructive Examination of Welds – General
Rules for Metallic Materials
. ASME V: Non-destructive Examination
This is actually Section V of the ASME BPV code and is
also specified by other ASME and API codes for their
NDE requirements.
European quality system requirements
. EN 719: Welding Coordination – Tasks and Responsibilities
Welding is a special process that requires the coordination
of welding operations in order to establish confidence in
welding fabrication and reliable performance in service.
The tasks and responsibilities of personnel need to be
clearly defined. This standard identifies the quality-related
responsibilities and tasks included in the coordination of
welding-related activities.
. EN 729: Quality Requirements for Welding – Fusion
Welding of Metallic Materials
This standard contains guidelines to describe welding
quality requirements suitable for application by manufac-
turers and is composed of the following parts:
○ Part 1: Guidelines for selection and use
○ Part 2: Comprehensive quality requirements
○ Part 3: Standard quality requirements
