subject: Thermostat Business Easily Face: The Safety Performance Of The National Standard Published [print this page] thermostat is a lot of Home Appliances Product must be equipped with the key components, product variety and wide application. In recent years, with the rapid development of China's home appliance industry, the whole plant purchases on the thermostat up year after year, joined the production team of businesses thermostat more and more. Industrial development process, manufacturers gradually realize that relying on national standards thermostat competition in the industry is becoming increasingly important. ( Click to enter the appliance accessories Column )
2009 , GB14536.10-2008 "for household and similar use automatic temperature sensing controls of the special requirements" (hereinafter referred to as "the special requirements for temperature sensing controls"), GB/T22687-2008 "Household and similar dual-metal temperature controller "(hereinafter referred to as" household and similar bimetallic temperature controller "), GB/T22688-2008" household and similar pressure type temperature controller "(hereinafter referred to as" pressure type of household and similar purposes temperature controller ") three national standards have been or to be implemented. On the thermostat manufacturers, the concern criteria, in accordance with the standards of the adjustment of product specifications become one of the important work this year.
Safety of primary importance
2008 9 19, the State General Administration of Quality Supervision, Inspection and Quarantine, the Standardization Administration issued a "special requirements for temperature sensing controls." June 1, 2009, began the formal implementation of this standard. According to the China Institute of Electric
Huangkai Yun said that "the special requirements for temperature sensing controls" for the enforcement of the national product safety standards, equivalent to using the International Electrotechnical Commission IEC60730-2-9: 2004 (2.2 version), "Household and similar use automatic controller 2? Part 9: Particular requirements for temperature sensing controls "in place of GB14536.10-1996" Household and similar use automatic temperature sensing controls of the special demands. " "Particular requirements for temperature sensing controls" applicable to the rated voltage not exceeding 690V, rated current up to 63A of household and similar electrical equipment used in electric automatic temperature-sensitive controller, or its terms together electronic automatic temperature-sensitive controller. Compared with the 1996 version of the standard, in breaking the limit devices based on the classification of increased ambient temperature for cooking utensils controller, self-cleaning type oven controller and Food Processing apparatus controller of structure containing the liquid metal parts increase the controller.
In addition, the "special requirements for temperature sensing controls," added the "thermal resistance requirements of the controller" and "The controller of agricultural greenhouse" normative appendix.
Reference to "special requirements for temperature sensing controls" on June 1 implementation of the "electrical" interview to the thermostat manufacturers have all said to be in strict accordance with national standards for production, testing. There are also thermostats manufacturers that the "special requirements for temperature sensing controls" in the specification of a number of technical parameters of production levels below the industry standard index set at some low. In response, Huang Kaiyun told reporters: "" the special requirements for temperature sensing controls "is a product safety standards, the industry's access threshold is a temperature control products for all the minimum requirements, its purpose is to ensure the implementation of machine product safety thermostat to prevent occurrence of accidents on this part. "
Performance beyond the standard
Thermostat products for performance requirements, December 31, 2008 release of "household and similar bimetallic temperature controller" and "household and similar pressure type temperature controller," in 2009 on November 1 start date.
Through the interview, "Electric" is understood that these two criteria are based on previous amendments to published industry standards, not mandatory implementation of standards. "Household and similar bi-metal temperature controller" for household and similar purposes in the assembly does not exceed the rated voltage 690V, rated current up to 63A electrical appliances on, double-metal components for the temperature to control the temperature of the bi-metallic temperature-sensitive controller and to prevent overheating for the purpose of temperature-sensitive bimetallic limiter.
