Introduction

Almost all (including for electric and electronic products) non-metallic materials when heated will produce smoke. Tobacco is one of the risk of fire, smoke Cause human and material damage and obstruct fire fighting. Therefore, reducing the rate of fire during the material/product can reduce smoke generation equipment Damage conducive evacuation and emergency services to intervene.

This section provides the use of GB/T 5169.27-2008 instrument described electric and electronic products in the material was measured to produce smoke blur experiment method.

GB/T 5169.28-2008/IEC/TS60695-6-31:1999 Fire hazard testing for electric and electronic products Part 28. Smoke obscuration - Small-scale static test -material

1 Scope

GB/T 5169 provisions of this section under certain experimental conditions, materials in confined spaces (ie no ventilation) perpendicular to the presence or absence of exposure Measurement of optical density when pilot flame heat radiation generated by the smoke.

This section applies to planar solid electrical and electronic products used in non-metallic material samples.

This method is not used to test the thermal non-planar products, such as wire and cable insulation, because such samples can not get a satisfactory Flux distribution.

From the current perception of the actual fire point of view, this method may not be used under the direct impact of the heat flux will melt and flow away without distributing Material smoke.
