This standard is a revision of GB/T5153-1985. Foreword
GB/T5153-2003
This standard defines a new brand naming rule, and according to this plan, the brands of the original standard are renamed. In accordance with international development, 13 screens such as M99.95, AZ31HAZ61A.AZ63B.AZ80AAZUID.MIC, AZIT.A231S.AZ61SAZ805, M25.ZK615, etc. are added.
This standard will replace GB/T515.3-1985 from the date of implementation. Appendix A of this standard is a regulatory appendix and Appendix I is an informative appendix. This standard was proposed by China Nonferrous Metals Industry Association, issued by National Technical Committee for Standardization of Nonferrous Metals, drafted by Northeast Light Metal Co., Ltd. This standard was issued by China Nonferrous Metals Standardization and Metrology Research Institute, and drafted by Ling Oufeng, Ge Wenxin, Wang Jie, Fu Mingshuang, Shan Changzhi, Yu Juncai, Fan Zhike, Zhu Yuhua, and Ma Cunzhen. This standard was issued by National Technical Committee for Standardization of Nonferrous Metals and is responsible for interpretation. The previous version of this standard is: GB/T5153-1585. 1 Scope Grades and chemical compositions of wrought magnesium and magnesium alloys This standard specifies the grades and chemical compositions of wrought magnesium and magnesium alloys. CB/T·5153-2003 This standard applies to wrought magnesium and carbon alloy products (plates, bars, tubes, molds, etc.) and the bricks and plates used therein. 2 Normative references The clauses in the following documents become the clauses of this standard through reference in this standard. All previous dated reference documents and all subsequent amendments (excluding other contents) or revised versions are not applicable to this standard. However, the provisions of this standard shall not apply to any other documents. The parties to the agreement shall study whether the latest version of this document can be used. For undated references, the latest version shall follow this standard. GB/T8170 Validity Rules
