This standard specifies the test method for moisture regain of chemical fibers - oven method. In case of dispute, use the thermal weighing method in the box, and correct the drying quality measured under non-standard atmospheric conditions to the value under standard atmospheric conditions. The correction method is shown in Appendix A. When this method is not applicable, the relevant parties shall agree on the corresponding test method . Appendix B applies only to polyester. This standard applies to polyester (polyester), polyamide (nylon), polyacrylonitrile (acrylic), polypropylene (propylene), polyvinyl formal (vinylon), polyvinyl chloride (chlorine), cellulose fibers, etc. Test of moisture regain of chemical fibers.
