My new house all the glass without the 3C logo, is not unqualified?
I told you about the popular ah:
You can go to humiliate your property:
First of all, 1750 * 1750 so big glass must be safe glass, the current practice is to strengthen the steel or steel
Second, all the hollow windows are finished, not to the scene cut, there is no corresponding equipment such as butyl rubber machine, two-component plastic machine, the production line (this can not, but the effect is very poor pressure , A direct result of watertight and air tightness) is not made of hollow glass,
Then, the tempered glass is not cut
Finally, the insulating glass, tempered glass can be safe glass, but the safety of glass not only two of them, the current safety glass is mainly steel and plastic, and then use them to synthesize hollow,
In summary, you can certainly say that your home windows are not in accordance with the requirements of the installation of the corresponding glass, this is in the affirmative.
1, if you want to check whether the glass is qualified, it should be cut before the glass is not checked, after cutting you can not check the 3C Peugeot. (In general this is the case).
2, insulating glass: insulating glass invented by the Americans in 1865, is a good insulation, noise, beautiful and applicable, and can reduce the building weight of the new building materials, it is two (or three) glass , The use of high-strength high air tightness composite binder, the glass and desiccant containing aluminum alloy frame bonding, made of high-performance insulation glass insulation. Hollow glass is superior to ordinary double-layer glass, so it has been recognized around the world, the insulating glass is two or more pieces of glass with effective support evenly separated and sealed around the seal, so that the formation of dry between the glass layer of gas Space glass products. The main material is glass, aluminum spacing, bending bolt, butyl rubber, polysulfide, desiccant.
3, safety glass: a class of severe vibration or impact is not broken, even if broken is not easy to hurt the glass. Including tempered glass, laminated glass and so on. For doors and windows of cars, aircraft and special buildings.
4, tempered glass: tempered glass is actually a kind of prestressed glass, in order to improve the strength of the glass, usually using chemical or physical methods, the formation of compressive stress on the glass surface, the glass bear the external force first offset the surface stress, thereby enhancing the carrying capacity , Enhance the glass itself, wind pressure, cold and heat, impact and so on.
Property funny funny, actually come up with this naive ridiculous argument to come. Tempered glass will play 3c, but can also choose not to play. For the tempered glass is certainly not 3c. Do you understand that?
Is not unqualified, but because the glass is ordinary glass, ordinary glass is no 3C logo, and tempered glass has 3C logo, because the tempered glass is a mandatory product catalog, and ordinary glass is not.
3C logo:
CCC is the abbreviation of "china compulsory certification". CCC constitutes the basic pattern of China's compulsory certification mark. According to the "Regulations on the Administration of Compulsory Product Certification" (May 26, 2009, the People's Republic of China State Administration of Quality Supervision, Inspection and Quarantine No. 117, since September 1, 2009 shall come into force), the state on human health and safety, animal and plant Life and health, as well as environmental protection and public safety products to implement a mandatory certification system. As of February 12, 2017, mandatory product catalog a total of 21 categories of 149 kinds of products.
