Introduction

The design of all electrical and electronic products needs to consider the fire risk and potential fire hazard. Design of components, circuits and parts

And the purpose of material screening is to reduce the potential fire risk to allowable even if foreseeable misuse, failure and failure occur.

s level. The purpose of GB/T 5169 "Fire Hazard Test for Electrical and Electronic Products" is to reduce the number of fires or reduce the severity of fires.

To save lives and protect property. It can be passed.

--- As far as possible to prevent live parts from triggering ignition, if ignition occurs, the scope of the fire should also be limited to the enclosure of electrical and electronic products;

--- Minimize the spread of the flame to the product shell as much as possible, and burn including heat, smoke, toxic or corrosive gases, etc.

The harmful effects of the product are minimized.

GB/T 5169 is now composed of 33 parts, divided into three sub-fields.

--- Fire hazard test evaluation guidelines and terminology standards, including 1 term and 5 evaluation guidelines, aimed at the professional field

Provide guidelines and reference procedures for fire hazard assessment;

---Small-scale fire test standards, including 4 glow wire/hot wire basic test methods, 8 flame test methods, and 2 abnormal resistance

The thermal capacity test method is intended to introduce the methods applicable to electrical and electronic equipment manufacturers and testing institutions, based on specific heat source models.

A small-scale test method for the heat source that is intended to cause a fire;

---The hazard assessment standard of combustion flow, including 2 corrosiveness, 2 smoke blur, 5 toxicity, 2 heat release, 2 flame surface

Spread, the purpose is to provide measurement of the combustion flow toxicity, corrosivity, smoke blur and heat release of electrical and electronic products and their materials

The guidelines and current technical status of test methods.

The fire hazard test of electrical and electronic products is best to accurately reproduce the actual fire conditions. If it is not feasible,

The near ground simulates the actual occurrence conditions and the exposure of materials, parts, components or components under this condition to conduct a fire hazard test. Book

The document gives guidelines for the evaluation and selection of alternative materials, components or assemblies for the manufacture of finished products based on preselected tests.

This revision of GB/T 5169.9 is consistent with the level of international standards after the revision, which is conducive to improving my country's electrical and electronic products

To better promote trade, exchanges and technical cooperation.

Fire hazard test for electric and electronic products

Part 9.Guidelines for Fire Hazard Assessment

General rules for pre-selection test procedures

1 Scope

This document provides guidelines for the evaluation and selection of alternative materials, components or components for the manufacture of finished products based on preselected tests.

This document describes how the pre-selection provides a comparative fire hazard test method to evaluate the performance of the sample, and in the design process of the finished product

How to use preselection to select materials, parts, components and assemblies. At the same time, it further describes how to use standardized test methods as

A part of the decision-making process to minimize the fire hazards of electrical equipment. It takes into account the expected response to the fire performance of the finished product to

And the environmental conditions may have an impact on the performance of the finished product.

This document is intended for product committees to prepare standards based on the principles specified in IEC Guide104 and ISO /IEC Guide51.

One of the tasks of the Product Committee is to use this series of standards wherever applicable when compiling standards in this field. Unless relevant

The standard specifically mentions or lists, otherwise the requirements, test methods or test conditions of this document will not apply.
