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 (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.
