Different standards are often encountered in the selection process of electric locks and hardware. At present, the more commonly used standards are European and American standards. The current standards in locks and hardware around the world mainly include the following:
·British Standard BS (BS5872-1982) is the oldest
·European standard EN (PREN12529) covers everything
The American standard ANSI (ANSI156.2-1999) is the most complete
·The Australian Standard AS (AS4145.2-1993) is the most stringent “trade barrier”
·The Japanese standard JIS (JIS+A1510-1995) is looser.
The one-way comparison between the European standard and the American standard is as follows.
1. American National Standard: ANSI+156.4, American Underwriters Laboratory UL10C.
·First-level standard opening times: ≥ 2 million times
·Number of opening times of secondary standard: ≥1 million times
·Three-level standard opening times: ≥500,000 times
2. European standard CE: EN+1154 (performance test) and EN+1634 (fire test), index of opening times: ≥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. This is also the reason why American standard electric locks or hardware products on the market are more expensive.
For a large commercial building, the number of doors may be thousands or even thousands. How to choose the most cost-effective electric lock and hardware solution for doors with different parts and different usage requirements to ensure a long service life and the lowest maintenance in the future is a very complicated and tedious task. The best overall solution for hardware locks should be a unity of convenience, safety and durability.
