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 s 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 (12.7 mm or 0.5 in. of water).
Read and record the individual test results in SI units as cm/s/cm and in inch-pound units as ft/min/ft rounded to three significant digits.
