The National Standardization Management Committee released the nine home appliance after-sales service standards on the 7th. This is the first batch of "national" prefix common standards in the field of home appliance service in China. The content covers the general requirements of after-sales service in the home appliance industry and 8 refrigerators, air conditioners and water heaters. Special requirements for category. Experts in the industry stated that under the current situation of the lack of service standards for home appliances and uneven service levels, such a batch of standard collectives will be introduced to implement, which will greatly standardize China's home appliance after-sales service market and promote the overall level of home appliance service.
For a long time, China's home appliance after-sales service market has no clear standard for service companies, employees, and safety requirements. The lack of relevant standards has made home appliance business services their own services and their service levels have been uneven.
Although there are some sporadic standards in the field of home appliance service, most of them are behaviors of the enterprises themselves. Although some may be called industry standards, they are also limited to a certain category of household appliances and a certain aspect. The general standards of the entire industry, National standards are still blank. In response to this problem, Haier undertook the secretariat's National Household Electrical Appliances Standardization Technical Committee Household Appliances Service Subcommittee to organize the drafting and validation of nine national standards such as the General Requirements for After-sale Service of Household and Similar Electrical Appliances.
Qi Yunshan, Director of Services of the China Region of Haier Group, said on site that the release of nine national standards is just a starting point. Haier, as a leading company in the after-sales service of home appliances, will continue to work hard to promote the implementation of national standards in various enterprises and continue to participate in the revision and improvement of home appliances. The service standard system promotes the overall level of the home appliance service industry.
The aspheric lens uses a single element design, which helps reduce the number of lenses in the optical assembly. Unlike spherical lenses, aspheric lenses have a more complex surface, and the curvature of the surface gradually changes from the center of the lens to the edge of the lens. The most significant advantage is that it can correct the spherical aberration caused by the Spherical Lens in the collimation and focusing system. One of the applications of aspheric lenses includes focusing the output from a laser diode, which not only reduces the overall cost, but also outperforms components designed using traditional spherical optical lenses.
The asphere's more complex surface profile can reduce or eliminate spherical aberration and also reduce other optical aberrations such as astigmatism, compared to a simple lens. A single aspheric lens can often replace a much more complex multi-lens system. The resulting device is smaller and lighter, and sometimes cheaper than the multi-lens design.Aspheric elements are used in the design of multi-element wide-angle and fast normal lenses to reduce aberrations. Small molded aspheres are often used for collimating diode lasers.
