Historical Standard: ASTM E1961-98 Standard Practice for Mechanized Ultrasonic Examination of Girth Welds Using Zonal Discrimination with Focused Search Units
SUPERSEDED (see Active link, below)
ASTM E1961
1. Scope
1.1 This practice covers the requirements for mechanized ultrasonic examination of girth welds. Evaluation is based upon the results of mechanized ultrasonic examination. Acceptance criteria are based upon defect limits defined by an Engineering Critical Assessment (ECA) or other accept/reject criteria defined by the Contracting Agency.
1.2 This practice shall be applicable to the development of an examination procedure agreed upon between the users of this practice.
1.3 The values stated in SI units are to be regarded as the standard. The inch-pound units given in parentheses are for information only.
1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
