Porcelain keyless lamp holder is made out of an electrical insulating material that can withstand high temperatures. Electrical insulators such as Porcelain prevent heat and electricity from transferring from one metallic device to another. Replacement Porcelain keyless lamp holder is corrosion resistant and can come with a moisture gasket that makes it suitable for outside use. Porcelain light sockets are found in antique lamps, vintage lamps and lamps that use halogen light bulbs or heat bulbs.
Lamp holder Fire and flame testing:
Insulating parts retaining live parts and the external shock of the insulating parts, should be able to withstand the GB / T 5169.10 glow-wire test requirements:
Sample is finished lamp. In order to test the lamp can be removed from the independent part, but must ensure that the test conditions and practical conditions are basically the same.
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.
