We have no amendments or corrections for this standard. See Sections 6 and 7. 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 astmm amount of extractable material to effect a significant mass change.

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.
