What is the difference between standard aluminum profiles and non-standard aluminum profiles?

What is not within the scope of the national standard is called non-standard, and what is within the scope of the national standard is called non-standard. \x0d\ At present, the domestic implementation standards for aluminum alloy profiles mainly include: \ x0d \ (1) GB 5237.1~ 5-2008, GB 5237.6-2004 \ x0d \ For aluminum alloy profiles for construction, that is to say, as long as they are used in the construction industry, their products. \x0d\(2)GB/T6892-2006 Industrial aluminum and aluminum alloy extruded profiles \x0d\ industrial aluminum alloy profiles refer to other aluminum extruded profiles except those used for building doors and windows, curtain walls and indoor and outdoor decoration. Except for a few products, most of the standards are GB/T6892-2006 Industrial Aluminum and Aluminum Alloy Extruded Profiles. \ x0d \ (3) GB/T 26014-2010 Non-architectural aluminum alloy decorative profile \ x0d \ Non-architectural aluminum alloy decorative profile refers to decorative aluminum alloy hot extrusion profile whose main purpose is to improve visual effect. If there are special requirements for the dimensional deviation of decorative profiles, it shall be indicated in the contract. Unless otherwise specified, it shall comply with GB/T 14846-2008 "Dimensional Deviation of Aluminum and Aluminum Alloy Extruded Profiles". Products are mainly used in automobile interior and exterior decoration, household appliances accessories, kitchen utensils, electronic appliances, interior decoration, medical equipment, instrumentation, office facilities and other fields. \x0d\(4)GB/T 14846-2008 Dimension Deviation of Extruded Aluminum and Aluminum Alloy Profile \x0d\ Another standard of industrial aluminum alloy profile should be GB/T 14846-2008 Dimension Deviation of Extruded Aluminum and Aluminum Alloy Profile. However, this standard is only for the extrusion size of industrial aluminum profiles, and only those with size requirements can be produced according to this standard. Other requirements are in line with GB/T6892-2006 standard. \x0d\(5) Advanced foreign standards \x0d\ Advanced foreign standards include: EU EN 12020-2, 6060 and 6063 Aluminum and aluminum alloy precision profiles Part 2: Allowable deviation of size and shape, EN755-2, aluminum and aluminum alloy bars, pipes and profiles-mechanical properties, and American ANSIH35.2. \x0d\(6) Enterprise Standards \x0d\ If there are no national standards, industry standards and local standards for the products produced by enterprises, corresponding enterprise standards shall be formulated as the basis for organizing production, and the enterprise standards shall be filed with the local technical supervision bureau according to the prescribed procedures. The quality and technical supervision system implements localized management. After market supervision spot checks and sampling, it is necessary to go to the quality and technical supervision bureau where the enterprise is located to read the filing standards before judging whether it is qualified. Production enterprises can immediately know that products are subject to supervision and spot checks, actively follow up the product inspection process and results in advance, and take corresponding treatment measures. Such as small materials, non-building profiles, decorative profiles and export profiles.
