Textile Testing Equipment Microcomputer Servo Fabric Gas Permeability Tester

Microcomputer Servo Fabric Gas Permeability Tester

Test Procedure:

1.Test the conditioned specimens in the standard atmospherefor testing textiles, which is 21±1°C (70±2°F) and65±2 % relative humidity, unless otherwise specified in amaterial specification or contract order.

2. Handle the test specimens carefully to avoid alteringthe natural state of the material.

3. Place each test specimen onto the test head of the testinstrument, and perform the test as specified in the manufacturer'soperating instructions.

4. Place coated test specimens with the coated sidedown (towards low pressure side) to minimize edge leakage.

5. Make tests at the water pressure differential specifiedin a material specification or contract order. In the absence ofa material specification or contract order, use a water pressuredifferential of 125 Pa (12.7 mm or 0.5 in. of water).

6.Read and record the individual test results in SI units ascm³/s/cm² and in inch-pound units as ft³/min/ft² rounded tothree significant digits.
