This Standard specifies the primary, secondary, and fifth sampling plans and sampling procedures based on the rejection quality level (expressed as the percentage of rejected products or the number of rejected products per hundred units) as the quality indicator. It is applicable to the inspection for process stability.

This Standard specifies the method of using the hand-feeling softness tester to determine the softness of paper. This Standard is applicable to various wrinkle toilet paper, tissue paper and its derivatives, as well as other papers that require softness.

This Standard specifies a method of determining the grammage of paper and board. This Standard applies to various papers and boards.

This standard specifies two methods for determining the chlorine content of vinyl chloride homopolymers and copolymers containing no plasticizers or additives, that is: - Method A (burning bomb); - Method B (burning bottle).

The standard of this method applies to the test of the tack of pressure sensitive adhesive tapes and those products similar to pressure sensitive adhesive tapes.

This Standard specifies the order contents, dimension, shape, technical requirements, test methods, inspection rules, packaging, marking and quality certificate of the high-carbon chromium bearing steel.

This Standard specifies the principle, definitions, symbols and designations, test piece and its dimension measurement, testing apparatus, conditions of testing, property determination, rounding off of numerical values of determination results, and test report for tensile testing of metallic materials. This Standard applies to determination of tensile properties of metallic materials at ambient temperature. Whereas, the tensile testing for the metallic products with a small cross section dimension such as metal anchors, ultra-fine wires and capillary tubes requires separate agreement.
