In the process of electric lock and hardware selection, different standards are often touched. At present, the commonly used handle lock standards are European standard and American standard. The current standards in the world of locks and hardware mainly include the following: British Standard BS (BS5872- 1982) The oldest; European standard EN (PREN12529) is all-encompassing; American standard ANSI (ANSI156.2-1999) is the most complete; Australian standard AS (AS4145.2-1993) is the most stringent "trade barrier"; Japanese standard JIS (JISA1510) -1995) The one-way comparison between the European standard and the American standard is more relaxed as follows. American National Standard: ANSI 156.4, Underwriters Laboratories UL10C. The number of first-class standard opening times: ≥ 2 million times; the number of secondary standard opening times: ≥ 1 million times; the number of third-level standard opening times: ≥ 500,000 times. European standard CE: EN1154 (performance test) and EN1634 (fire test), open times indicator: ≥ 500,000 times.
It can be seen from the above comparison that the durability parameters of American standard products are generally higher than those of European standard products, which is also the reason why the American standard electric locks or hardware products are relatively expensive on the market. Electric cabinet door locks For a large commercial building, the number of connecting rod locks may be thousands or even thousands. How to choose the best cost-effective electric lock and hardware solution for different parts and different use requirements to ensure a long service life and the lowest maintenance in the future is a very complicated and cumbersome work. The best overall hardware lock solution should be a unit of convenience, safety and durability.
The principle of selection of electrical cabinet locks is comprehensive. When selecting intelligent building electric locks and hardware solutions, it is recommended to follow the following basic selection principles: the places used and their importance should be considered in the main entrance, hall door, room, bathroom. Or use on the channel to select the product suitable for the required function; the environment and conditions for the use of the switchgear lock require consideration of the pros and cons of the use environment, such as the frequency of use, whether it is a fire door, the structure of the door, weight, thickness, etc.; Consider the situation of the people who are frequently used, consider whether there are elderly people, children or people with disabilities; consider the coordination of the electrical cabinet lock and the decorative environment, should consider the coordination and matching with the decorative environment should be consistent
