This method is only applicable to solid, non-metallic sample plane. Does not apply to non-planar samples such as insulated wires and cables, because such products can not obtain a uniform heat flux distribution. This standard does not provide for the material classification.

Introduction
Any circuit need to be considered a fire hazard. Element design, circuit design, material selection and design of equipment for the purpose of reducing
Less likelihood of fire, even in the foreseeable abnormal use, failure and failure is also the case.
Originally fire victims electric and electronic products, but may contribute to fire. One of the risk of fire is increased release of smoke, people depending on
Sleep and reduce (or) disoriented and not from building fire escape or influence.
In fact, all non-metallic materials (including those used in electric and electronic products) will release smoke when heated. Fire resulting
Smoke can cause human and material losses and the impact of fire fighting. Therefore, reducing the rate of fire of the material/product can reduce smoke generation equipment
Loss, ease of evacuation and emergency measures.
This section provides vertical test material exposed to radiation heat source (with or without a pilot flame) created under smoke than light density meter
Control, calibration procedures and basic test procedure.

Instrument Description
1 Scope
This section GB/T 5169 describes the determination of vertical material exposed to a radiant heat source (with or without a pilot flame) arising under smoke
The ratio of the optical density of the instrument calibration procedures and basic test procedure. Test sample size has been determined. Optical density was measured in advance with a reference
Controlled substance test calibrated pressure control box is carried out.
This method is only applicable to solid, non-metal plane samples. Does not apply to non-planar samples, such as wire and cable insulation, because it
Kind of products can not obtain a uniform heat flux distribution.
This section does not provide for the material classification.
This method is not applicable in the heat of the direct impact melt and flow out of the material, because it can not obtain reproducible results.
Warning. Because the test sample pyrolysis or burning will produce toxic and harmful gases, so to take appropriate security measures.
