MH/T 6040 Test method for smoke density of aviation materials  –  Overview of standards

This standard specifies solid aviation materials or components （ Including insulated conductor ） Method for determination of smoke density of combustion or thermal decomposition . This standard is applicable to measuring and describing the thermal reaction and fire reaction of aviation materials under controlled conditions , Not applicable to describing or evaluating materials 、 product 、 Hazards or dangers of structures or components under actual fire conditions .

MH/T 6040 Test method for smoke density of aviation materials – Test principle

The basic principle of the test method specified in this standard is Bouguer's law （Bouguer’sLaw）, That is, the smoke accumulated in the closed box according to the combustion or thermal decomposition of the tested material （ Suspended solids or liquid particles ） The resulting light attenuation , The smoke density is derived from the geometric factor and the measured light transmittance .
