コンプライアンス概要

この概要は現在英語のみで提供しています。

適用範囲

This standard applies to the design and management of newly built, expanded, and reconstructed foundry workshops, including technical renovation and technology introduction projects. It covers facilities involved in steel casting, iron casting, and non-ferrous metal casting. Existing foundry workshops and manufacturers of foundry equipment must also comply with these regulations.

技術要求

The standard mandates comprehensive dust control measures starting from process and equipment design, requiring the use of low-dust generating technologies. It specifies detailed requirements for enclosure and sealing of all crushing, screening, mixing, and cleaning equipment to prevent dust escape. Manufacturers must ensure that all dust-generating processes are equipped with appropriate local exhaust ventilation systems. It outlines specific dust removal strategies for various foundry operations, including furnace melting (electric arc furnaces, cupola furnaces, and non-ferrous furnaces), raw material handling, molding, core making, shakeout, and casting cleaning. The standard dictates the use of mechanical exhaust and purification devices, such as bag filters and electrostatic precipitators, tailored to the specific equipment and process. The standard also sets strict criteria for the design of ventilation and dust removal systems, including ductwork sizing, airflow velocity requirements, and the selection of filtering materials based on gas temperature, humidity, and chemical properties. System interlocking with process equipment is required to ensure ventilation activates prior to production equipment. Additionally, it includes mandatory requirements for the management and supervision of dust control work, integrating it into overall safety production management. This includes establishing maintenance systems, regular testing of dust concentrations, and mandatory training for personnel working in dust-exposed environments.

試験方法

The standard outlines evaluation procedures primarily based on airflow velocity measurements at enclosure openings and exhaust hood faces. It requires regular monitoring of dust emission concentrations and system performance parameters, including air volume and pressure. Facilities must conduct semi-annual tests of dust concentration in work areas and exhaust emissions to verify compliance with national occupational health and environmental standards.

よくある質問

What facilities are regulated under GB 8959-2007?

The standard applies to the design and management of new, expanded, or renovated foundry workshops for steel, iron, and non-ferrous castings. Existing foundry workshops and equipment manufacturers must also comply.

Are there any significant updates from the previous GB 8959-1988 version?

The 2007 version restructures the content based on the foundry process flow for easier reference. It adds definitions, introduces new dust removal equipment for large-capacity melting furnaces, updates parameters for resin sand processes, and removes obsolete limestone sand processes.

Does GB 8959-2007 reference any other specific standards?

It references several national standards, including GB 9078 for industrial furnace air pollutant emissions, GB 16297-1996 for comprehensive air pollutant emissions, and GB 50019 and GB 50243 for HVAC design and construction acceptance.
