Research Of Solar Water Heater Detection Technology In China Compulsory Certification

China Compulsory Certification (CCC) for household appliances is to strictly control product quality and ensure safety of person and property, and solar water heaters with auxiliary electrical heating are within the scope of this certification.However, due to their special nature, there are a number of problems and disputes in CCC of these products. Therefore, scientific analysis and reasonable solution of these problems have important theoretical significance and application value to reasonably and efficiently implement the compulsory quality certification of such products, ensure their safety performance and better protect the interests of consumers.Based on the preliminary investigation and the complete review of domestic and overseas literature, this paper analyzed the current situation of domestic and overseas product certification systems, in particular the origin, development and problems of CCC.This paper mainly studied the solar water heater with auxiliary electrical heating, analyzed and researched the status of CCC testing technology for solar water heaters, summarized the problems existing in the existing type test and made suggestions to optimize and improve CCC type testing process.The author combined years of experience in testing such products, comprehensively analyzed the traditional type testing process, identified the causes of long test cycle and proposed the solution accordingly. The author then used the optimized solution for testing solar water heaters. The demonstration of the improved test process showed that the optimized testing solution effectively improved the testing efficiency and accuracy, greatly reduced CCC type testing cycle of such products, and brought important practical value and economic benefits to the testing organization and enterprise.After the type testing process of the solar water heater was optimized, the applicability of the existing testing standard was further studied. In combination with the temperature sampling test, feasible optimization and improvement of the testing standard were proposed, which further improved the certification and testing technology of the solar water heater and had certain practical significance for improving the certification and testing level of the solar water heater.Restricted by time and conditions, this paper is not enough for the applicability study of the existing certification standard, for it is not easy to improve a testing standard. The certification body is expected to pay attention to and encourage more people to participate in the study on the practicability of certification standards so as to better ensure the safety performance of products and protect the interests of consumers.
