IEC **********0(UL *4)Flammability Classification testing to  Plastics Material

Ecosafene Products Service Co.,Ltd have rich experience to provideIEC **********0(UL *4)Flammability Classification testing to Plastics Material

IEC **********0(UL *4)Flammability Classification testing to Plastics Material- Principle

IEC **********0 Fire hazard testing - Part ****0: Test flames **0 W horizontal and vertical flame test methods

IEC **********0(UL *4)Flammability Classification testing to Plastics Material - Scope

IEC **********0:***3 specifies small-scale laboratory test procedures intended to compare the burning behaviour of different materials used in electrotechnical products when vertically or horizontally oriented test bar specimens are exposed to a small flame ignition source with a nominal thermal power of *0 W.

These test methods determine either the linear burning rate or the self-extinguishing properties of materials.

These test methods are applicable to solid and cellular materials that have an apparent density of more than **0 kg/m3, determined in accordance with ISO **5.

Two test methods are described.

Method A is a horizontal burning test and is intended to determine the linear burning rate of materials under specific test conditions.

Method B is a vertical burning test and is intended to determine whether materials self-extinguish under specific test conditions.
