【国外标准】 IEEE Draft Guide for Determination of Test Specimens for Seismic Qualification for Building Code Applications

This guide establishes selection criteria that is used to determine representative components or devices and assembly specimen configurations (both indoor and outdoor) to test as part of seismic qualification efforts for attaining building code seismic conformance for nonstructural equipment in commercial and industrial applications. Additionally, guidance for specific acceptance criteria is provided. Equipment types covered by this guide include those covered by the following standards: * IEEE… read more Std C37.04, AC High-Voltage Circuit Breakers with Rated Maximum Voltages above 1000 V * IEEE Std C37.20.1, Metal-Enclosed Low- Voltage (1000 Vac and below, 3200 Vdc and below) Power Circuit Breaker Switchgear * IEEE Std C37.20.2, Metal-Clad Switchgear * IEEE Std C37.20.3, Metal-Enclosed Interrupter Switchgear (1 kV-38 kV) * IEEE Std C37.20.9, Metal-Enclosed Switchgear Rated 1 kV to 52 kV Incorporating Gas Insulating Systems * IEEE Std C37.21, Control Switchboards * IEEE Std C37.23, Metal-Enclosed Bus * IEEE Std C37.74, Subsurface, Vault, and Padmounted Load-Interrupter Switchgear and Fused Load-Interrupter Switchgear for Alternating Current Systems up to 38 kV * IEEE Std C37.121, IEEE Guide for Switchgear - Unit Substation - Requirements read less
