    Abstract - (Show below) - (Hide below)

    Specifies methods and requirements for the manual ultrasonic testing of full or partial penetration fusion welded joints in carbon and low alloy ferritic steels, 6 mm or greater in thickness. The Standard employs four sensitivity levels and gives procedures for the sizing of discontinuities. Appendices give guidance on the ultrasonic testing of welds and the identification of discontinuities.

    Scope - (Show below) - (Hide below)

    This Standard sets out methods and requirements for the manual ultrasonic testing of full or partial penetration fusion welded joints in carbon and low alloy ferritic steels, 6 mm or greater in thickness, using A-scan presentation and employing four sensitivity levels. This Standard does not cover the testing of stainless steels.It does not cover the testing of longitudinal welds when-(a) the radius of curvature of fabrications is less than 125 mm; or(b) for tubular fabrications having an outside diameter exceeding 250 mm, the ratio of thickness to outside diameter exceeds 0.22.NOTE: Advice and recommendations on information to be supplied by the purchaser at the time of enquiry or order are contained in the purchasing guidelines set out in Appendix A.
