Scope of standard 1.1 This specification covers a nondestructive evaluation of the strength and continuity of parallel PVC geomembrane seams separated by an unwelded air channel. The unwelded air channel between the two distinct seamed regions is sealed and inflated with air to a predetermined pressure. Long lengths of seam can be evaluated by this specification more quickly than by other common nondestructive tests.1.2 This specification can be used as a substitute for destructive testing or used in conjunction with destructive testing.1.3 This specification covers PVC sheet 0.760 mm (0.030 in.) and thicker.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.
