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, manufacture, and installation of fixed metal guardrails and platforms used in workplaces within industrial enterprises. It explicitly excludes installations on nuclear facilities, ships, lifting machinery, power transmission towers, mast towers, communication towers, and meteorological towers. This standard is mandatory for industrial facilities operating in China. It serves as a crucial compliance document for engineers designing industrial access systems.

技術要求

The standard outlines general requirements, including platform inclination angles, material selection, and the setup of guardrails and toe boards. Manufacturers must ensure guardrails are installed when the vertical height exceeds 1200mm. It also covers anti-corrosion and lightning protection grounding requirements. It details structural requirements for guardrails, specifying guardrail heights based on the vertical height to the falling surface. The standard regulates the spacing of posts, top rails, handrails, and intermediate rails to prevent falls. Specific dimensions for toe boards are also established to prevent object drop hazards. For platform structures, it defines the minimum dimensions for work platforms, walking platforms, and intermediate platforms. It specifies overhead clearance requirements and platform board specifications, including anti-slip measures and maximum allowable gaps between adjacent plates or gratings. A significant update in this version is the introduction of requirements for self-closing gates and mezzanine gates, including their load capacities and structural functions. Additionally, it mandates the provision of usage instructions and warning information, referencing GB 2894 for safety colors and signs.

試験方法

While primarily a design and installation standard, it specifies structural load verification procedures to ensure safety. Guardrails and platforms must withstand specific concentrated live loads and distributed live loads, with strict limits on allowable deflection. Construction quality acceptance must align with referenced standards such as GB 50205 and GB 50576. Compliance verification involves structural load testing and installation quality inspection. Materials must also meet performance requirements for bearing capacity and deformation under environmental conditions.
