Causte hardware selection process often come into contact with different standards. At present, the commonly used handle lock standards are the European standard and the American standard. The current global standards for locks and hardware mainly include the following: British Standard BS ( BS5872-1982) is 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 as follows. American National Standard: ANSI156.4, Underwriters Laboratories UL10C. First-level standard opening times: ≥2 million times; second-level standard opening times: ≥1 million times; third-level standard opening times: ≥500,000 times. European standard CE: EN1154 (performance test) and EN1634 (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 door locks or hardware products on the market are more expensive. For a large commercial building, the number of door locks may be hundreds or even thousands. How to choose the most cost-effective door locks and hardware solutions 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. causte Hardware provides customers with a complete set of door lock hardware solutions.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.
