Significance and Use
This practice is a nondestructive evaluation intended to be used for quality control purposes during factory or field seaming of geomembranes.
This practice may also be used to evaluate geomembrane panels for holes that penetrate the entire thickness of material. Limitations on the test practice are that it may not be suitable for uneven or curved surfaces, thick seams, seams in corners, and thin extensible geomembranes.
Scope
1.1 This practice covers procedures to perform nondestructive quality control testing described in Practice D 4437 and D 4545 for evaluating the continuity of all types of geomembrane seams using the bubble emission or vacuum chamber method.
1.2 The technique described in this practice is intended for use on geomembrane seams, patches, and defects.
1.3 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.
