Option 3 uses either Option 1 or Option 2 extraction but provides for calculation of extractable matter from the loss in mass of the material due to the extraction rather than the extractable matter residue. Please first verify your email before subscribing to alerts. The average results from the two laboratories should be compared using asmt statistical analysis and a probability level chosen by the two parties before the testing begins. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to asstm.

We have no amendments or corrections for this standard. In case of a dispute arising from differences in reported test results using this test method for acceptance testing of commercial shipments, the purchaser and the supplier should conduct comparative tests to determine if there is a statistical bias between the laboratories.

If a bias is found, either its cause must be found and corrected, or the purchaser and supplier must agree to interpret future test results with consideration to the known bias. Extractables by mass loss is frequently used for textiles which have a relatively large amount of extractable material to effect a significant mass change.
