This standard was proposed by the China Petroleum and Chemical Industry Federation. This standard is under the jurisdiction of the National Chemical Standardization Technical Committee (SAC/TC63). This standard was drafted. Sinopharm Chemical Reagent Co., Ltd., Beijing Chemical Reagent Research Institute Co., Ltd., Taizhou City Volume Supervision and Inspection Institute. The main drafters of this standard. Zheng Qi, Gu Xiaoyu, Han Baoying, Chen Haoyun, Li Jianhua, Meng Rong, Wang Yuhua, Huang Yinbo, Wang Linping. Chemical reagent classification1 ScopeThis standard specifies the classification and coding rules for chemical reagents. This standard applies to survey statistics, data analysis, research and development production, experimental application, standard management and scientific regulations classified by chemical reagents. Waiting.2 classification2.1 Classification method This standard is divided into three levels according to the line classification method, which are large, medium and small. Medium and small classes have containment items, small classes In principle, it belongs to the middle class and is the basic type that constitutes the middle class. For the middle class that cannot be subdivided or the individual is small, it is no longer divided into small classes. 2.2 Major categories Chemical reagents are divided into the following ten categories according to product use. a) basic inorganic chemical reagents; b) basic organic chemical reagents; c) high purity reagents; d) reference materials/standard samples and controls (excluding biochemical reference materials/standard samples and controls); e) chemical reagents for chemical analysis; f) chemical reagents for instrumental analysis; g) chemical reagents for life sciences (including biochemical reference materials/standard samples and controls); h) isotope chemical reagents; i) special chemical reagents; j) Other chemical reagents. 2.3 Medium and small classes Each major category is divided into the following intermediate and minor categories according to their different characteristics and their internal relationship. a) Basic inorganic chemical reagents are divided into 8 sub-categories and 78 sub-categories according to the elemental or compound structure; b) Basic organic chemical reagents are divided into 28 subclasses and 124 subcategories according to the structure of the compound; c) High purity reagents are divided into 10 intermediate categories according to their use; d) Standard materials/standard samples and reference materials are divided into 3 sub-categories and 24 sub-categories according to their purposes; e) Chemical reagents for chemical analysis are divided into 6 sub-categories and 9 sub-categories according to their purposes; f) Chemical reagents for instrumental analysis are divided into 19 intermediate categories according to their use; g) chemical reagents for life sciences are divided into 8 sub-categories and 18 sub-categories according to the combination of compound structure, properties and uses; h) Isotope chemical reagents are divided into 2 subclasses and 14 subcategories according to their purposes; i) Special chemical reagents are divided into 11 sub-categories and 20 sub-categories according to their purposes; j) Inclusion of other chemical reagents for chemical agents that cannot be classified as described above. ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of GB/T 37885-2019_English be delivered?Answer: Upon your order, we will start to translate GB/T 37885-2019_English as soon as possible, and keep you informed of the progress.
