Qinun Fabric Thickness Gauge has a complete assortment of the presser-foot and weights to conform to different test-methods. The textile samples shall be conditioned and the test conducted in the standard atmosphere for conditioning and testing of textiles specified in ISO 139. The test procedure is shown as below: C lean the presser-foot and the reference plate. C heck that the presser-foot shft moves freely. L oad the presser-foot to exert the appropriate specified pressure on the reference plate, and set the thickness gauge to read zero. A n applied pressure of (1 ±0.01 )kPa is recommended. R aise the presser-foot and position the sample or test specimen, without tension and distortion, on the reference plate so that no part of the area to be measured is closer than 150mm to the selvedge . E nsure that the area chosen for the test is free from crease. L ower the presser-foot gently onto the specimen and note the gauge reading after (30 ±5 )s. D eterm...
