The Chinese standards for molybdenum rods are mainly formulated by the Standardization Administration Committee of China (SAC). The following are some common Chinese standards related to molybdenum rods:
GB/T 4181-2003 “Molybdenum rods”: specifies the classification, size, appearance quality, technical requirements, test methods, signs, packaging, transportation and storage of molybdenum rods.
GB/T 4182-2003 “Molybdenum Alloy Bars”: specifies the classification, size, appearance quality, technical requirements, test methods, signs, packaging, transportation and storage of molybdenum alloy bars.
GB/T 3620.1-2018 “Methods for Chemical Analysis of Molybdenum and Molybdenum Alloys Part 1: Determination of Molybdenum in Molybdenum Rods – Sodium Permanganate-Acid Oxidation Titration Method”: Describes the method for the determination of molybdenum content in molybdenum rods.
GB/T 3620.2-2018 “Methods for Chemical Analysis of Molybdenum and Molybdenum Alloys Part 2: Determination of Chemical Composition in Molybdenum Rods – Inductively Coupled Plasma Emission Spectrometry”: specifies the method for the determination of chemical composition in molybdenum rods.
These standards cover the classification, size, quality requirements, and chemical composition analysis methods of molybdenum rods, and are used to guide the production, quality control and application of molybdenum rod products.
