Siemens and the new flight, etc. The new domestic gas was sampled with failure - Gas stove, water he

To enhance product quality supervision, protection of life and property safety, and guide consumers rational consumption, Guangdong Provincial Quality Supervision Bureau in the domestic fuel products with a random inspection. Relevant information is as follows:

(A) of the sample results The sample of 227 domestic gas production of 336 batches of a product, on examination, qualified 264 batches, the batch of qualified products was 78.57%. One sample of household Gas stoves 202 batches of products, qualified 142 batches, batch passing rate of 70.30 percent, up batches of such products in 2007 passing rate of 27.50%, increased by 42.8 percentage points; domestic gas instantaneous Water heater 128 batches of products, qualified 116 batches, batch passing rate of 90.63%, up batches of such products in 2007 passing rate of 70.54 percent, increased 20.09 percent; dual-use furnace 6 batches of products, qualified six batches , lot 100% pass rate.

(B) Overall quality and substandard project analysis
Sampling results show that the Government departments to enhance the quality of the product control production processes, through special rectification of failed companies to track the checks and so on, enables companies to enhance the quality consciousness, to further improve product quality. The supervision and random household gas with product quality compared with a 2007 has been enhanced, but there are some problems. Unqualified items mainly include: air tightness, thermal aquatic rate Electric Performance, flame stability, heat load and deviation, the flue gas carbon monoxide content, function, thermal efficiency, gas source identification, the general structure of the flame failure protection devices and the size and structure of the intake manifold.

Failed largely because companies in the assembly process is not strictly, factory inspection process have not been examined or not tight; manufacturers to cut costs, reduce the number of heat exchanger on the heat transfer film, resulting in smoke high temperature, high temperature flue gas heat has not been fully absorbed, resulting in inefficient water heater's heat exchanger; the same time, increase the heat load will affect the combustion conditions, a company with a hot load of small burner to replace a large burner heat load , resulting in thermal aquaculture, thermal load and thermal efficiency of all surpassed the accuracy of a negative bias, or does not meet requirements; water heater thermal load of the structure does not match with the combustion chamber, combustion is not enough space required, the burner injector pipe size too small, can not guarantee an adequate air coefficient, can not guarantee the normal combustion, or combustion in the flue jams worsening rapid increase of carbon monoxide in the flue gas; business understanding of the standard deviation in the ground terminal connected to the valve or valves on have not taken measures to compression, grounding and unreliable; selected key components - pressure switch often pass, can not play too much pressure to cut off electrical circuit functions; business is not seriously implement the new standards, still remain in the heat load on the old standard, unqualified failure for the C class of knowledge items.

(C) after processing Found for this sample the quality of various products, our bureau in accordance with relevant laws and regulations, increased post-processing efforts: First, order the product failure and to recover the failed enterprise deadline for correction products; the second is serious quality-standard requirements companies have to inform the Municipal Quality Supervision Bureau, according to the law for investigation; 3 is incorporated into the production license and the compulsory product certification and production enterprise, be dealt with according to law. Fourth, product quality analysis will be held, please give business experts to explain the standards for quality, substandard products to help manufacturers identify problems, analyze the reasons for product failure to formulate corrective measures and urge the enterprises to implement; 5 is released according to the law of this good quality spot check some of the products and their manufacturers and part of the list of serious quality problems of products and manufacturers list, guide consumption; 6 is the problem for the existing regional quality products focused on the quality of alerts sent out to conduct special rectification. Also failed to further increase product quality supervision and spot check tracking and regulating the market, promoting production enterprises to improve product quality.
