In terms of tracking and spot checks, 35 companies were found to be unqualified in the previous spot check. 8 companies still failed the spot check and 27 companies were qualified.
In terms of household gas appliances, a total of 435 batches of household gas appliances produced by 431 companies were inspected in this random inspection, and 31 batches of products were found to be unqualified. The unqualified detection rate was 7.1%.
The overall unqualified discovery rates for this type of products in the past three years are 11.1%, 9.5%, and 7.1%.
Among these products, the unqualified detection rate of gas-fired water heaters is the lowest at 1.4%.
Household gas appliances are appliances that use the heat released by gas combustion to heat food, prepare hot water, and provide heating. They can meet the needs of cooking, bathing, and heating, and are closely related to people's lives.
The spot check involved 15 provinces (cities) including Guangdong, Beijing, Tianjin, Hebei, among which 361 batches of industrial cluster Guangdong Province were spot-checked, accounting for 83.0% of the total number of spot checks, and the unqualified discovery rate in Guangdong Province was 7.8%.
The inspection items of household gas appliances are divided into safety performance indicators and use performance indicators. The safety performance indicators include the air tightness of the gas system and the carbon monoxide content in the flue gas in an airless state. The use performance indicators include thermal efficiency.
The spot check of each product is as follows.
Household gas instantaneous water heaters: This time, a total of 137 batches of products produced by 137 enterprises in 9 provinces (municipalities) were spot-checked, and 12 batches of products were found to be unqualified. The unqualified detection rate was 8.8%, a decrease of 1.7 percentage points from the previous spot check.
The unqualified items involve flame stability, thermal efficiency, safety devices for preventing dry burning, carbon monoxide content in flue gas in an airless state, hot water production rate, grounding measures, etc.
Household gas stoves: Randomly inspected 228 batches of products produced by 224 enterprises in 10 provinces (municipalities). Among them, 18 batches of products were unqualified. The unqualified detection rate was 7.9%, which was 3.1 percentage points lower than the previous random inspection.
The unqualified items involve heat load, dry flue gas concentration, flameout protection devices, thermal efficiency, and gas ducts.
Gas-fired heating water heaters: 70 batches of products produced by 70 enterprises in 8 provinces (municipalities) were randomly inspected. One batch of products was unqualified. The unqualified discovery rate was 1.4%, which was a decrease of 0.6% compared with the previous random inspection.
The unqualified items involve failures of water temperature limiting devices and thermostats.
The reason for the disqualification was that the safety temperature limiter, which should be installed at the outlet end of the batch of products, was mistakenly installed at the return water end during assembly, which caused the outlet water temperature to be too high, and no installation problems were found during the factory inspection, resulting in the product disqualification.
In terms of explosion-proof electrical products, 159 batches of explosion-proof electrical products produced by 158 companies were randomly checked this time. 157 batches were inspected and 37 batches of products were found to be unqualified. The unqualified detection rate was 23.6%. The qualified discovery rate exceeds 25%.
From 2019 to 2021, the overall unqualified detection rate for this type of product is 25.6%, 32.4%, and 23.6%.
Explosion-proof electrical products are special products, mainly used in coal, oil and gas, petrochemical and chemical industries, and are directly related to safe production.
This time, the focus was spot-checked on safety items such as impact resistance test, explosion-proof joint surface, and enclosure pressure test.
Among the unqualified items found, the explosion-proof joint project accounted for the highest proportion, reaching 26 batches, 9 batches of impact resistance test projects, and 5 batches of shell pressure test projects.
The spot check of each product is as follows.
Explosion-proof lamps and lanterns: 67 batches of products produced by 67 enterprises in 11 provinces (autonomous regions and municipalities) were spot-checked, and 19 batches of products were found to be unqualified. The unqualified discovery rate was 28.4%.
The unqualified items involve impact resistance test, clamping test of non-armoured cables and cables with braided coating, additional requirements for the introduction of flameproof enclosures, flameproof joints, enclosure pressure test, and maximum surface temperature.
This time, the focus was spot-checked on the production enterprises in two industrial concentration areas in Zhejiang Province and Guangdong Province, and the unqualified detection rates were 24.3% and 25.0% respectively.
Explosion-proof motors: 24 batches of products produced by 24 companies in 7 provinces (autonomous regions and municipalities) were randomly checked. One batch was suspected of being produced without CCC certificate, which has been handed over to the market supervision department where the company is located.
23 batches of products were inspected, and 9 batches of products were found to be unqualified. The unqualified discovery rate was 39.1%. The unqualified items were impact resistance test and flameproof joint surface.
Explosion-proof electrical appliances: 68 batches of products produced by 67 enterprises in 11 provinces (autonomous regions and municipalities) were randomly checked. One batch was suspected of being produced without CCC certificate and has been handed over to the market supervision and management department where the company is located.
67 batches of products were inspected, and 9 batches of products were found to be unqualified. The unqualified discovery rate was 13.4%.
The unqualified items involve flameproof joints, creepage distance, enclosure pressure test, impact resistance test, and maximum surface temperature.
According to the analysis of technical institutions, the main reasons for the quality problems of explosion-proof electrical products are: First, there are many types of explosion-proof electrical products. Most of the company's product parts or accessories need to be purchased externally, and some of the suppliers’ products cannot meet the requirements of explosion-proof, and the company does not comply with the requirements. Carry out purchase inspection; second, the requirements for the processing technology of the flameproof joint surface are high, and the ability of the workers is insufficient; the third is that some companies cut corners in the production process of the product shell, resulting in insufficient shell strength; fourth, the internal electrical components are selected incorrectly or the use of inferior products is used. The product generates a large amount of heat and affects the maximum surface temperature of the product.
