Introduction

All electrical and electronic products must be designed with fire risk and potential fire hazard in mind. Design of components, circuits and components

And the screening of materials is designed to reduce the potential risk of fire to even the foreseeable abnormal use, failure and failure.

To accept the level. This section together with GB/T 5169.2 and GB/T 5169.44 provides guidance on how to achieve this.

The primary purpose is to prevent ignition of the live parts, and if ignition occurs, the fire is also limited to the outer casing of the electrical and electronic products.

The secondary purpose is to minimize the extent to which the flame spreads outside the product, and to include heat, smoke, toxic or corrosive combustion products.

Harmful effects are minimized.

Fires involving electrical and electronic products may also be caused by non-electric external sources of ignition. This factor should be considered in the overall risk assessment.

Fire safety engineering refers to the improvement of scientific principles based engineering methods by analyzing specific fire conditions or quantifying a set of fire risks.

An application designed to assess the environmental aspects of the building to achieve the purpose of fire safety engineering.

This section provides fire protection safety engineering methods and performance test information for the product committee. The technical content relates to the original fire safety engineering.

And instructions for use, guidelines for the use of fire safety engineering in the design of electrical and electronic products, terms and definitions of fire safety engineering, fire protection

Performance, data, and test guidelines required for safety engineering assessment.
