The official website of the State Administration of Market Supervision notified the national supervision and spot check results of the quality of explosion-proof lamps and products, and 13 batches of products did not meet the standards.
This time, a total of 26 batches of explosion-proof lighting products produced by 26 enterprises in 7 provinces and municipalities including Liaoning, Shanghai, Jiangsu, Zhejiang, Jiangxi, Shandong and Guangdong were sampled.
This spot check is based on GB 3836.1-2010 "Explosive environment Part 1: General requirements for equipment", GB 3836.2-2010 "Explosive environment Part 2: Equipment protected by flameproof enclosure "d"", GB 3836.3-2010 "Explosive environment Part 3: Requirements for standards such as equipment protected by increased safety "e", explosion-proof signs, warning signs, grounding connections, impact tests, clearances, creepage distances, cables and conduits for explosion-proof luminaire products Clamping and sealing test of the device (cable clamping test, sealing device sealing performance test), flameproof joint surface parameters, outer casing pressure test, internal ignition non-explosion test, temperature, thermal drastic test (temperature measurement, thermal shock) Tests and other 10 items were tested.
The spot check found that 13 batches of products did not meet the requirements of the standard, involving explosion-proof signs, warning signs, grounding connections, impact tests, clamping and sealing tests for cables and conduit entries (cable clamping test, inlet sealing performance) Test), flameproof joint surface parameters, shell pressure test, temperature, thermal shock test (temperature measurement) project.
