This document provides the comprehensive list of Chinese Industry Standards - Category: SH; SH/T; SHT.
This Standard specifies the test method of thermal stability of heat transfer fluids of mineral oil and synthetic hydrocarbon type. This Standard is applicable to the heat transfer fluids used in the open system (the maximum operating temperature under normal pressure is less than its initial boiling point or boiling point) or closed system (the maximum operating temperature is more than its initial boiling point or boiling point).
This Standard specifies the determination method of colority of petroleum products. This Standard is applicable for various kinds of petroleum products, such as lubricating oil, kerosene and diesel etc.
This standard specifies the 2,2-bipyridine spectrophotometric method for the determination of iron content in pure adipic acid. This standard is applicable to the determination of iron content in pure adipic acid. AND the minimum determination concentration is 0.1 mg/kg.
This Standard specifies the determination method for the seal compatibility index of petroleum products. This Standard applies to petroleum products, excluding the ones containing water.
This Standard specifies the determination of filterability of lubricating oil taking mineral oil as base oil, especially the method for evaluating the filterability of hydraulic oil in hydraulic system. This Standard applies to oils with viscosity grade being not higher than 100 according to the viscosity classification provisions of GB/T 3141. This Standard does not apply to liquids taking other materials as base material, such as fire resistant fluid, because there may be compatibility problems between it and the filtration membrane used in this Standard. This Standard does not apply to hydraulic oil with special properties, because it may contain insolvable additives or partially dissolved additives or special macromolecular substances.
This part specifies the technical requirements, test methods, inspection rules, marking, packaging, transport, storage and safety of pure adipic acid. This part is applied to the pure adipic acid using the cyclohexane as raw materials, which is subjected to two-step oxidation to produce coarse adipic acid, AND then decolourized by activated carbon, recrystallized, separated and dried.
This Part specifies the thermogravimetric method for the determination of moisture content in pure adipic acid. This Part applies to the determination of the moisture content in pure adipic acid, the determination range is (0.050 ~ 0.300) % (mass fraction).
This standard specifies the determination method for the solution color of the pure adipic acid ammonium solution. This standard is applicable to the determination of the solution color of the pure adipic acid ammonium solution.
This Part specifies the spectrophotometric method for the determination of nitric acid content in pure adipic acid. This Part applies to the determination of nitric acid content in pure adipic acid. The minimum concentration is 0.3 mg/kg.
