Escopo e aplicabilidade

This standard specifies the basic safety requirements for various electrical equipments with AC rated voltages up to 1000V (1140V) and DC rated voltages up to 1500V, including handheld, movable, and fixed types used indoors and outdoors. It is applicable to products utilizing converted electrical energy from chemical, light, or wind sources. This standard is mandatory for manufacturers of general electrical equipment entering the Chinese market. It excludes materials, semi-finished products, medical electrical equipment, elevators, and specialized products for ships, aircraft, and railways.

Requisitos técnicos

The standard outlines comprehensive safety hazard protection requirements, covering protection against electric shock, mechanical hazards, and operational risks. It mandates a specific sequence of safety technical measures: direct, indirect, and indicative. Manufacturers must ensure products are designed to operate safely under expected and reasonably foreseeable use without endangering personnel or property. Chapter 6 details specific safety project requirements, including environmental adaptability, enclosure protection (IP codes), and protective earthing. It sets strict criteria for insulation properties, such as creepage distances, clearance, and dielectric strength, referencing GB/T 16935.1-2008 for specific coordination. Additional requirements cover thermal resistance, flame retardancy, and mechanical stability under various stress conditions. Furthermore, the standard addresses electromagnetic compatibility (EMC) for electronic circuits providing critical safety functions, requiring them to pass immunity tests like electrostatic discharge and voltage surges. It also specifies detailed requirements for safety signs, graphical symbols, nameplates, and user manuals to ensure proper safety information is conveyed. Compliance with all specified safety project requirements is verified through type testing.

Métodos de ensaio

Testing and conformity assessment are conducted as type tests in accordance with GB/T 25296. The standard allows for multiple testing methods for a single item, but the methods specified within the document serve as the arbitration methods. Key evaluations include dielectric strength tests, impulse voltage tests, mechanical impact and vibration tests, and EMC immunity tests. Products must pass all specified safety project tests on a single sample to be deemed compliant.

Perguntas frequentes

What products are regulated under GB 19517-2023?

It applies to handheld, movable, and fixed electrical equipments with AC voltages up to 1000V (1140V) and DC voltages up to 1500V, excluding medical equipment, elevators, and specialized transport products.

Are there any updates from the previous version of GB 19517-2023?

Yes, it replaces GB 19517-2009, adding normative references, terms, and a new chapter on safety project requirements, while deleting the implementation and supervision chapter.

How is conformity assessed under this standard?

Conformity is determined through type testing. A product is considered compliant only if it passes all specified safety project tests, typically conducted on a single sample.
