GB/T 34924-2017 Guidelines for safety related risk assessment and risk reduction for low voltage equipment

Scope

This standard is based on ISO/IEC Guide 51 and proposes general principles for risk assessment aimed at ensuring the safety of low-voltage electrical equipment. Based on knowledge and experience gained from the design, use, accidents, incidents, and injuries related to low-voltage electrical equipment, and in accordance with Chapter 6, the standard evaluates risks at all stages of the equipment's life cycle and implements risk reduction measures. Technical committees should appropriately adopt this standard. The standard provides additional guidance information for implementing risk assessment based on ISO/IEC Guide 51, GB/T 20002.1-2008, and GB/T 20002.2-2008. It specifies procedures for identifying hazards, estimating and evaluating risks (including risk comparison), and implementing necessary risk reduction measures. The risks covered by this standard include potential harm to people, property, and livestock. Technical committees are not required to adopt the standard's structure. The standard aims to provide guidance for technical committees in making safety decisions for low-voltage electrical equipment and preparing various supporting documents based on implemented risk assessments. When manufacturers can foresee the intended use, they can evaluate components that are not used independently. The standard applies to all types of electrical equipment with an AC voltage of 1,000 V or lower and a DC voltage of 1,500 V or lower. Low-voltage electrical equipment with inaccessible internal voltages exceeding 1,000 V AC or 1,500 V DC also falls within the scope of this standard. Product standards require that equipment manuals include necessary information for safe use of the equipment. The standard does not address electrical distribution systems, electrical systems, or components used in machinery, as the risks of these components largely depend on their use and assembly in electrical systems or devices. Note: The protective measures taken by product users depend on
