Note 1-Other standards for the determination of extractable matter in textiles made of specific fibers have been published by ASTM: No other units of measurement are included in this standard. The test specimens asm then be randomly assigned in equal numbers to each laboratory for testing. The average results from the two laboratories should be compared sstm appropriate statistical analysis and a probability level chosen by the two parties before the testing begins.
