APPLICATION

USAGE

TEST PROCEDURE

Handle the test specimens carefully to avoid altering the natural state of the material
Place each test specimen onto the test head of the test instrument and perform the test as specified in the manufacturer operating instructions
Place coated test specimens with the coated side down towards low pressure side to minimize edge leakage
Make tests at the water pressure differential specified in a material specification or contract order In the absence of a material specification or contract order use a water pressure differential of 125 Pa 127 mm or 05 in of water
Read and record the individual test results in SI units as cmscm and in inchpound units as ftminft rounded to three significant digits
