Guangzhou municipal quality and technical supervision 23, 2012 Guangzhou city holiday lantern product quality supervision and inspection results, there are 1 batches of enterprises do not meet the requirements of the standard.

It is reported that the total sample of 2 companies produced 2 batches of products, according to the national mandatory standards GB 7000.1-2007 "lighting part first: General requirements and tests," GB 7000.9-2008 "luminaires - Part 2-20: Particular requirements on" GB 17625.1-2003 ", light electromagnetic compatibility limits for harmonic current emission limits (equipment per phase the input current is less than or equal to 16A)," GB/T 15482 "product quality supervision of the small overall count of a sample testing program and sampling table" and other standards on the structure (conduit), external wiring (power connection), external wiring (cross-sectional area), internal wiring (cross-sectional area), protection against electric shock and durability test heat resistant and refractory, and tracking resistance (heat), heat and fire resistance and resistance to the mark (refractory), harmonic current test project.

The results showed that the nominal Guangzhou Municipal Lighting Company Limited production of a batch of LED lamp string (size: 3528 production date / batch number: 2012-2-14), protection against electric shock, fire and heat resistance, tracking resistance (heat) project failed.

Quality supervision department, said the heat resistance, fire resistance and electrical resistance marks (heat) project is the main material of the lamp string of the key performance indicators. Standard fixed charged parts material should be subjected to ball pressure test at 125 DEG C, the indentation should be less than 2mm, the lamp string fixed charged bolt materials subjected to ball pressure test, indentation is far greater than the standard requirements, respectively 7mm and 5.8mm, does not meet the standard requirements. Protection against electric shock protection project will be a threat to the user's personal safety.
