Foreword
This standard is an amendment to GB/T13586-92 "Aluminum and aluminum alloy waste, waste classification and technical conditions".
Compared with GB/13586-92, this standard has the following changes:
1. The physical classification of the original standard waste is grouped by the winning combination number. After revision, they are still classified in physical form, but the group revisions are grouped according to the name of the waste;
2. The original standard was too fine for the level of waste (mostly 6), and it was not easy to operate. After the revision, the level was reduced to 3 to 5, making it simple, versatile and easy to operate, and moving closer to ISRI standards;
3. The original standard is mainly aimed at the waste generated by the aluminum processing industry, which is convenient for enterprises to classify and recycle and use them directly. The revised standard also applies to the recycling, processing, and domestic and foreign trade of aluminum scrap in circulation;
4. Revised standards, with appropriate modifications to the technical requirements of waste, emphasizing the environmental requirements for waste;
5. Delete the reference standard in the original standard test method, emphasize the negotiation of supply and demand, and if there is any objection, carry out according to the analysis standards of the relevant country; this standard is proposed by China Nonferrous Metals Industry Association; this standard is measured by China Non-ferrous Metal Industry Standards. The institute is responsible for the administration. The standard was drafted by Beijing Zhongxue Recycled Metal Research Institute. This standard was drafted by Hebei Lizhong Nonferrous Metals Co., Ltd., Shanghai Xinge Nonferrous Metals Co., Ltd. and Zhejiang Wantai Aluminum Industry Co., Ltd.; the main drafters of this standard: Wang Jiwei, Zhang Xizhong, Yang Xiaojun, Ye Zonghui, Xu Hong, Li Xiarong. The standard is the National Technical Committee of Non-ferrous Metals Standardization Technical Committee responsible for the interpretation ()

1 Scope
This standard specifies the technical requirements, test methods, inspection rules and signs, packaging, transportation, and storage of aluminum and aluminum alloy scraps and wastes.
This standard is applicable to the recycling, processing and domestic and foreign trade of aluminum alloy scraps and scraps in the circulation field. It also applies to scrap aluminum scraps and scraps used in nonferrous metal smelters and processing plants.
