                             Introduction to Five Standards of Common Locks

      Different standards are often encountered in the selection of locks and hardware. At present, European and American standards are commonly used for handlocks. There are mainly the following standards in locks and hardware: British standard BS (BS5872-1982), European standard EN (PREN12529), American standard ANSI (ANSI 156.2-1999), Australian standard AS (AS4145.45). 2-1993) is the most stringent "trade barrier"; the Japanese standard JIS (JISA1510-1995) is more relaxed for the European and American standards of one-way comparison as follows. American National Standard: ANSI 156.4, UL10C, American Insurer Laboratory. The number of first-level standard opening: > 2 million times; the number of second-level standard opening: > 1 million times; the number of third-level standard opening: > 500,000 times. European standard CE: EN1154 (performance test) and EN1634 (fire test), opening number index: > 500,000 times.

          From the above comparison, it can be seen that the durability parameters of American standard products are generally higher than those of European standard products, which is also the reason why American standard locks or hardware products are more expensive on the market at present. For a large commercial building, the number of connecting rod locks may be thousands or even thousands. It is a very complicated and tedious work how to choose the best price-ratio lock and hardware scheme for different parts and different use requirements to ensure a longer service life and the lowest maintenance quantity in the future. The best overall solution of hardware locks should be the integration of convenience, safety and durability.

         The selection principle of locks for electrical cabinets synthesizes the above. When choosing the electric locks and hardware schemes for intelligent buildings, the following basic selection principles should be followed: the place used and its importance should be considered to be used in the doors, halls, rooms, bathrooms or passages in order to select products suitable for the required functions; the environment and conditions for the use of locks for switchgear cabinets require consideration of the use of rings. The advantages and disadvantages of the environment, such as the frequency of use, whether it is a fire door, the structure, weight, thickness of the door, etc. Consider the situation of frequently used personnel, whether there are elderly people, children or disabled people; Consider the coordination of electrical cabinet locks and decorative environment, should consider the coordination and matching with its decorative environment.
