The specimen is mounted on the bracket, 1N force applied to the top of the pressure in the glow-wire, filament Preferably, the distance from the test piece 15 mm in the upper part or larger than 15 mm, while in the center of the test surface. Glow-wire penetration depth of the specimen is limited to use mechanical methods 7 mm.

Glow wire temperature at the top of 650 ℃. 30 s after the specimen from the glow wire 696.
Before starting the test, the glow-wire temperature and heating current should be constant 1 min. But to ensure that heat radiation during this period shall not affect the sample. Sheathed thermocouple wire using highly sensitive measuring glow wire temperature at the top, the structure of the thermocouple calibration should meet the GB / T 5169.10 requirements.
Move away from the glow wire specimen, the specimen should be on any combustion flame extinguished in the 30s, and the whereabouts of any burning substance should not be lit in the sample below horizontal distance of 200 mm ± 25 mm of tissue.
E27 Porcelain lamp holder is not subjected to this test.
