Recently, the State Administration for Market Regulation released the "2024 National Supervision and Sampling Inspection Report on the Quality of 32 Products Including Household Electric Washing Machines". This report involves the national sampling of 73 batches of explosion-proof lamps. The results of this national sampling show that 73 batches of products from 73 explosion-proof lamp-related production and sales units in Zhejiang, Jiangsu, Shanghai, Beijing, Hebei, Guangdong, Anhui, Heilongjiang, Liaoning and other provinces (cities) were sampled. 21 batches of products were found to be unqualified, with an unqualified detection rate of 29%, which is consistent with the unqualified detection rate of the national sampling in 2023.


From the perspective of the unqualified items of the national sampling products, all 21 batches of unqualified products have unqualified product safety items. Among them, 14 batches of products failed the explosion-proof joint surface, with an unqualified detection rate of 19%, which was 2 percentage points lower than the national sampling in 2023; 8 batches of products failed the impact resistance test, with an unqualified detection rate of 10%, which was 1 percentage point lower than the national sampling in 2023; 8 batches of products failed the shell pressure resistance test, with an unqualified detection rate of 10%, which was 1 percentage point higher than the national sampling in 2023; 7 batches of products failed the clamping test of non-armored cables and cables with braided covering layers, with an unqualified detection rate of 10%, which was 9 percentage points lower than the national sampling in 2023; 1 batch of products failed the internal ignition non-explosion test, and the unqualified situation of this project was newly discovered this year. In addition, in this national sampling, 1 batch of products was also found to have failed the internal ignition non-explosion test.

        Explosion-proof lights are important industrial products related to production safety, and their quality is closely related to public safety and the safety of people's lives and property. From the perspective of unqualified items, there are still cases where the requirements of relevant mandatory national standards are not met. For mandatory national standards that should be 100% met, there is still room for improvement, which needs to be paid great attention by relevant companies.
