This Part specifies the visual colorimetric method and titration method used for the determination of potassium permanganate in organic chemical products.

This Part of GB/T 3903 specifies a test method for determining volatile organic chemical liquid products evaporated on a water bath after the dry residue.

This Part of GB/T 6324 specifies the instrument method that adopts the principle that was determined by International Commission on Illumination (CIE) in 1931, using X, Y, Z (tristimulus values) to express the color of clear liquid to determine the color (expressed in platinum-cobalt color). This Part is applicable to determine clarified, non-turbid liquid organic chemical products of which the nominal platinum-cobalt color number is 0~100 and the sample has similar absorption characteristics to the platinum-cobalt solution, without fluorescence emission.

This Standard specifies the PLATES.

This Part specifies the test methods for determination of carbonyl compounds in organic chemical products: spectrophotometric method and volumetric method.

This Standard specifies the thread form, basic size, tolerance, marking and gauge of pipe thread (NPT and NPSC) with sealed thread pair and thread form angle of 60-degree. This Standard is applicable to sealed thread connection for pipe, valve, pipe joint, cock, and other pipe fittings.

This standard specifies the requirements, test methods, inspection rules, packaging, transportation, quality forecast and purchase orders for copper slag concentrates. This standard applies to the copper slag concentrates for copper smelting which is obtained by flotation method of the slag produced during smelting and blowing during copper smelting.

This Standard specifies the requirements for the use and design of graphical symbol for age warning labelling for toys that are not suitable for children under 3 years of age. This Standard applies to the relevant requirements for graphical symbol for age warning labelling for toys that are not suitable for children under 3 years of age. It does not apply to the toys that are manifestly unsuitable for children under 3 years of age due to their function, size, characteristics, performance or other compelling reasons.
