According to the announcement, the Ministry of Industry and Information Technology approved 586 industry standards, including 32 for the chemical industry, 13 for the petrochemical industry, 9 for the ferrous metallurgy industry, 51 for the non-ferrous metal industry, 71 for the machinery industry, 43 for the automotive industry, 8 for the shipbuilding industry, 141 for the light industry, 35 for the textile industry, 2 for the packaging industry, 16 for the electronics industry, and 165 for the telecommunications industry. Additionally, it approved the English versions of 53 industry standards, such as "Evaluation Methods for Coagulation Performance of Water Treatment Agents," including 16 for the chemical industry, 4 for the non-ferrous metal industry, 3 for the rare earth industry, 8 for the building materials industry, 7 for the machinery industry, 2 for the light industry, 3 for the textile industry, and 10 for the telecommunications industry.
Introducing the 8 translated foreign language versions of the building materials industry standards: "Fragmentized Building Materials Small Hollow Block JC/T 2369-2016 (2017)" in English, which is titled "Fragmentized Building Materials Small Hollow Block." This standard outlines terms and definitions, classification, raw materials, technical requirements, testing methods, inspection rules, as well as product certification, transportation, and storage for the small hollow blocks made from building debris, suitable for industrial and civil buildings.
《Long Stone JC/T 859-2020》, titled "Feldspar", specifies the product classification, requirements, testing methods, inspection rules, as well as marking, packaging, transportation, and storage of feldspar products. It applies to potassium feldspar and sodium feldspar ore blocks, as well as powdered materials processed mechanically.
"Roll-Compression Non-Asbestos Fiber Gasket Materials JC/T 2052-2020" specifies the classification and marking, requirements, testing methods, inspection rules, as well as labeling, packaging, transportation, and storage of roll-compressed non-asbestos fiber gasket materials. These materials are primarily reinforced with fibers not containing asbestos, bonded with elastomers and auxiliary reinforcing materials, and supplemented with other fillers, forming sheet materials used for manufacturing sealing gaskets. Gaskets made from such sheet materials can also be referenced.
"Non-metallic Sealing Filler JC/T 2053-2020""tallic sealing packing" specifies the classification and marking, requirements, testing methods, inspection rules, as well as marking, packaging, transportation, and storage of non-metallic sealing fillers. It is applicable to sealing fillers and filler rings made from non-metallic materials that do not contain asbestos. Pure graphite filler rings can also be used in accordance with this specification.
"Natural Sodium Bentonite Impermeable Padding JC/T 2054-2020"The "Nite Impervious Liner" standard defines terms and definitions, classification and marking, requirements, testing methods, inspection rules, as well as markings, packaging, storage, and transportation for natural sodium bentonite impermeable liners. It is applicable to impermeable liners primarily made of natural sodium bentonite, with both sides covered by geotextile (film) or plastic boards, stitched or bonded by needle punching. These liners are mainly used for waterproofing and impermeable projects in fields such as subway systems, tunnels, artificial lakes, power plants, landfill sites, airports, water conservancy, road and bridge construction, and buildings. The impermeable liners specified in this document are not suitable for waterproofing and impermeable projects involving high-concentration electrolyte solutions.
"Fused Cast Alumina-Zirconia-Silica Refractories for Glass Furnaces, JC/T 493-2015(2017), specifies the terminology and definitions, product classification and marking, technical requirements, sample preparation, testing methods, inspection rules, as well as labeling, packaging, transportation, storage, and quality certificates for fused cast alumina-zirconia-silica refractories used in glass furnaces."
"Dense Zirconium Silicate Bricks for Glass Furnaces, JC/T 495-2013(2017)" specifies the terminology and definitions, classification, shapes and dimensions, technical requirements, testing methods, inspection rules, as well as marking, packaging, transportation, storage, and quality certificates for dense zirconium silicate bricks used in glass furnaces. It is applicable to dense zirconium silicate bricks used in glass furnaces, produced from zircon sand as raw material through processes such as isostatic pressing, mechanical pressing, or other methods, and sintered at high temperatures.
"Magnesia Alumina Spinel Bricks for Cement Kilns JC/T 2036-2010 (2017)" specifies the terminology and definitions, classification and marking, technical requirements, testing methods, inspection rules, labeling, packaging, transportation, storage, and quality certificates for magnesia alumina spinel bricks used in cement kilns.
