Foreword

This document is in accordance with the provisions of GB/T 1.1-2020 "Guidelines for standardization work Part

1.Structure and drafting rules for standardization documents" Drafting. This document replaces GB 30080-2013 "Safety Production Code for Copper and Copper Alloy Casting" and GB 30187-2013 "Safety Production Code for Copper and Copper Alloy Casting". Compared with GB 30080-2013 and GB 30187-2013, in addition to structural adjustments and editorial changes, the main technical The technical changes are as follows:

--- Changed terms and definitions (see Chapter 3, Chapter 3 of GB 30080-2013 and GB 30187-2013);

--- Added the setting requirements and safety protection requirements for the molten copper (slag) area (see 5.1.5, 5.1.7, 5.2.9, 5.2.10);

--- Added safety requirements for combustion devices (see 6.2.2.1, 6.2.2.2, 6.2.2.3, 6.2.3.1, 6.2.3.2, 8.2.8);

--- Changed the requirements for accident pits (see 6.2.1.9,

7.5 of GB 30187-2013);

--- Changed the requirements for emergency water (see 6.2.1.4, 6.3.2, 8.1.3, 6.2.2,

10.1.4 of GB 30187-2013);

--- Deleted the requirements for induction furnace lining erosion monitoring and furnace leakage early warning (see

6.2.6 of GB 30187-2013);

--- Deleted the following. The production of products containing toxic elements such as beryllium and cadmium must use vacuum melting and the combustion system of the vertical furnace should be set with an automatic air/fuel ratio Rate control system, etc. (see

6.2.8 of GB 30187-2013);

--- Deleted the combustion system requirements for shaft furnaces (see

1 Scope

GB 30080-2025 is the Chinese national standard on safety specification for design and production of copper and copper alloy melting and casting, in the field of environment and health protection, safety. It carries no /T suffix, which in the Chinese system means compliance is mandatory: a product or a practice within its scope has to meet it to be lawfully made, sold or carried out in China. It was issued on 1 August 2025 by the State Administration for Market Regulation; Standardization Administration of China, and has been in force since 1 February 2026. Classification: ICS 13.100, CCS H09. This page is published from the official record of the standard held by the Chinese standards administration: the identification, the dates, the classification and the issuing body are taken from there. The clause text, the tables and the numeric limits are in the document itself, which is delivered complete in English translation.

This document specifies the safety management, regional layout and building (structure), equipment design in the process of copper and copper alloy processing enterprises in the casting production process. Safety technical requirements for facilities, supporting public auxiliary systems and operations. This document applies to the design and production safety management of melting and casting projects for new construction, expansion and renovation of copper and copper alloy processing enterprises.
