ASTM D8231-19 PDF Download

ASTM D8231-19 is a standard practice that outlines the use of a low voltage electronic scanning system for detecting and locating breaches in roofing and waterproofing membranes. The standard emphasizes the importance of correcting membrane breaches during and after installation to prevent premature failure of the membrane and damage to the structure. The practice describes a specific method using a low voltage, dual sweep, scanning system to locate breaches in waterproof membranes. This method is intended to be a part of the quality assurance process for roofing and waterproofing membranes.

The standard also mentions that the described method can be used for forensic testing of existing roofing and waterproofing membranes, although there are specific limitations that apply. The standard provides detailed technical procedures for using the electronic scanning system on both horizontal and vertical surfaces to locate potential leaks in exposed roofing and waterproofing membranes. It emphasizes that this practice should be used in conjunction with visual or other methods of inspection, rather than as a replacement for them. The standard also highlights the importance of regularly calibrating the detection and location equipment to ensure maximum confidence in the results.
