The values stated in each system are not exact equivalents; therefore, each system shall be used independently of the other. It is the responsibility of the user of this standard to ast, appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
Always use the same weight and plane angle.
The procedure is generally applicable to all types of woven and knitted apparel fabrics.

The test results from the two laboratories should be compared using a statistical test for unpaired data, at a probability level chosen prior to the testing series.
Pilling Resistance Testing of Textile Fabrics Using ASTM and AATCC
Current edition approved Dec. The visual standards are most advantageous when the laboratory test specimens correlate closely in appearance with worn fabrics and show a similar ratio of pills to fuzz. Selection, Number, and Preparation 9. Add another 25 mg see Note 6 of 6-mm 0.
Originally approved in With asrm or 4 pilling test chambers. These factors are not evaluated when pilling is rated solely on the number of pills.
No universal standard fabric is available. Specimens should be staggered in such a manner that no two specimens contain the same yarns. Vacuum all specimens in this manner. Pills are caused to form on fabric by a random rubbing action produced by tumbling specimens in a cylindrical test chamber lined with a mildly abrasive material. The pilling resistance of a speci? The rounded end of a glass stirring rod works well, also, but caution should be used to prevent breakage and possible injury from broken glass.
