Some standard content:
GB/T 4879—1999
Rust-proof packaging is a protective measure taken to prevent the metal surface of the product from chemically changing during circulation and causing corrosion, which may affect the product quality.
This standard mainly revised the following contents when GB/T4879—1985 Rust-proof Packaging was revised: the rust-proof packaging grades A, BCD in the original standard were revised to rust-proof 1, 2 and 3 packaging. Appendices A, B, C and D in the original standard were cancelled. The cleaning, drying, rust-proofing and packaging of the rust-proof packaging methods were revised to Appendix A. From the date of implementation, this standard will replace GB/T4879—1985. Appendix A of this standard is a prompt appendix.
This standard was proposed by China Packaging Corporation. This standard is under the jurisdiction of the National Technical Committee for Packaging Standardization. The responsible drafting units of this standard are: Mechanical Science Research Institute, Wuhan Anti-Rust Paper Factory, and Hangzhou Lin'an Special Adsorbent Factory. The main drafters of this standard: Li Xuelong, Xiao Huaibin, Jia Xinlong, Dong Yiliang, Li Xiaofeng. This standard was first issued on January 28, 1985. 390

Table 1 Anti-rust packaging grades
It is difficult for water vapor to penetrate, and the trace amount of water vapor that penetrates is absorbed by the desiccant. After the product is cleaned and dried by the anti-rust packaging, there is no oil stain or water mark on the surface of the product. Only a small amount of water vapor can penetrate when the methods A3 and A4 in Appendix A are used alone or in combination. After the product is cleaned and dried by the anti-rust packaging, there is no oil stain, sweat mark or water mark on the surface of the product. Only a small amount of water vapor can penetrate when the methods A3 and A4 in Appendix A are used alone or in combination. After the product is cleaned and dried by the anti-rust packaging, there is no dirt or oil mark on the surface of the product. Only a small amount of water vapor can penetrate when the methods A3 and A4 in Appendix A are used alone or in combination. 5.1.1 Determine the anti-rust packaging grade and package it according to the grade requirements to ensure that the product does not rust during the anti-rust period. 5.7.2 The anti-rust packaging operation process should be continuous. If it is interrupted, temporary anti-rust treatment should be taken. 5.1.3 During the anti-rust packaging operation, organic pollutants such as hand sweat should be avoided from contaminating the product. 5.1.4 If the product that needs to be treated with anti-rust is in a hot state, in order to avoid the loss or decomposition of the anti-rust agent due to heat, it should be cooled to near room temperature before treatment.
5.1.5 If the product coated with rust inhibitor needs to be wrapped with inner packaging materials, neutral, dry and clean packaging materials should be used. 5.1.6 For products that use rust inhibitors to prevent rust, the rust inhibitors should generally be removed when unsealed for use. If the coating or removal of rust inhibitors will affect the performance of the product, rust inhibitors should not be used. 5.2 Material requirements
5.2.1 The following materials can be used for indirect rust prevention: desiccant (silica gel, montmorillonite, etc.), vapor phase corrosion inhibitor (dicyclohexyl nitrite, benzotriazole, etc.).
5.2.2 The following materials can be used for direct rust prevention: anti-rust oil, anti-rust grease, anti-rust paper, anti-rust agent, anti-rust liquid, vapor phase rust oil, vapor phase rust paper, etc.
5.2.3 The quality of the anti-rust materials used in the product should comply with the provisions of the relevant product standards. 5.2.4 The desiccant should comply with the relevant provisions of GB/T5048. 5.2.5 Gas phase anti-rust packaging materials shall comply with the relevant provisions of GB/T14188. 5.2.6 Inner protective packaging materials shall comply with the relevant provisions of GB/T12339. 5.2.7 In addition to the necessary relevant tests, the compatibility of anti-rust packaging materials shall comply with the relevant provisions of GB/T16265, the contact corrosion of packaging materials shall comply with the relevant provisions of GB/T16266, and the gas phase corrosion inhibition capacity of packaging materials shall comply with the relevant provisions of GB/T16267.

5.3 Environmental requirements
Anti-rust packaging operations should be carried out in a clean, dry environment with small temperature differences. 6 Anti-rust packaging methods
6.1 Anti-rust packaging is divided into four steps: cleaning, drying, anti-rusting and packaging. 6.2 The anti-rust packaging method of the product should be determined according to the following conditions: a) the characteristics of the product and the degree of surface processing; b) the period of transportation and storage; c) the environmental conditions of transportation and storage; d) the degree of load that the packaging bears during the circulation of the product; e) the anti-rust packaging level. 6.3 After determining the anti-rust packaging method, the method A1 in Appendix A can be used for cleaning to remove dust, grease residue, sweat and other foreign matter on the surface. 6.4 After cleaning the metal surface of the product, the method A2 in Appendix A can be used to dry it immediately. 6.5 After cleaning and drying the metal surface of the product, the method in Table A3 in Appendix A can be used for rust prevention. 6.6 After cleaning, drying and rust prevention of the metal surface of the product, the method in Table A4 in Appendix A can be used for packaging. Test Method
7.1 The anti-rust packaging test shall be carried out in accordance with the provisions of the periodic exposure test A in GJB145A. For level 1 packaging, 3 periodic exposure tests may be selected. For level 2 packaging, 2 periodic exposure tests may be selected. For level 3 packaging, 1 periodic exposure test may be selected. 7.2 After the periodic exposure test, unpack and check whether the product and the selected materials have rust, aging, cracks or other abnormal changes. 8 Marking
The packaging should be marked with moisture and heat-sensitive signs according to the provisions of GB191. 393
