To safeguard the legitimate rights and interests of consumers, State organizations on heating radiator products quality inspection for a country. Total check out Beijing, Tianjin, Hebei, Henan, and Shandong, Liaoning, Jilin, Shanghai, Zhejiang, etc. 9 provinces and municipalities 55 enterprises producing 55 kinds products (not involved in the export product), product quality sampling rate 95.4%.
This spot checks according to the GB/T13754 the heating radiator heat quantity measurement, JG220 the aerofoil copper aluminum compound radiator, steel plate JG2 the radiator "and other criteria, on heating radiator fin height, vertical and flange highly, highly, soldering surface quality, thickness, width, thread precision, paint film impact, film adhesion, heat resistance, thermal paint films, hydrostatic test, the same side and export Center distance, brass minimum wall thickness, coating surface, expansion combined stress, 17 projects were examined.
Checks in the major quality problems:
1. heat dissipation of the individual products. Heat dissipation is heating radiator products of key performance indicators. Spot checks in certain product heat emission indicator below standard requirements.
2. individual product thread precision is unqualified. By radiator must constitute a threaded connection to cycle heating system. Spot checks in certain product thread precision is not eligible to join easily heat sink is not good, can not even assembled correctly, even if reluctantly, assembled with even, it is easy to thread connection, leakage, seepage or burst.
For checks in the major quality problems, AQSIQ has tasked the quality and technical supervision departments around according to the product quality law and other related laws and regulations, on the spot checks in the quality of production enterprises in accordance with the law and grace period. At the same time on the quality of better products and production enterprises, guide consumption. The State will continue to increase heating radiator products inspection, and promote overall level the heat sink product quality.
