NEW ASTM STANDARD FOR LEAK DETECTION
BY CHAD HERRICK, TECHNICAL DIRECTOR, DETEC ELECTRONIC LEAK DETECTION

ASTM-D8231 Standard Practice for the Use of Low Voltage Electronic Scanning System for Detecting and Locating Breaches in
Roofing and Waterproofing Membranes was published July 1, 2019 and provides a detailed a procedure for performing Electronic Leak
Detection (ELD) on roofing and waterproofing. D8231 expands on the scanning platform method described in ASTM D7877 Standard
Guide. D8231 creates a more detail-oriented solution for ELD, dedicated to the scanning platform with two important additions.
One pertains to the electrical properties of the membrane and the substrate under the membrane. Technical advancements reflected
in the new ASTM practice allow conductive and semi-conductive membranes such as black EPDM and cold fluid applied membranes
to be tested. D8231 mandates that the membrane have a surface resistance greater than 10^7 ohms-per-square. The substrate under
the membrane must have a surface resistance less than 10^4 ohms-per-square. See www.global.ihs.com to purchase the standard.
