Test Method D3822 using test specimens having gauge lengths of 10 mm [0.4 in.] or greater is considered satisfactory for acceptance testing of commercial shipments since the test method has been used extensively in the trade for acceptance testing. Critical differences noted in Tables 1 and 2 were obtained on man-made fibers having a gauge length of 25 mm [1.0 in.] and 250 mm [10 in.]. Natural fibers or fibers having lesser or greater gauge lengths may provide different values and may require comparative testing
