· British Standard BS (BS5872-1982) is the oldest;
· European standard EN (PREN12529) is all-encompassing;
· The American standard ANSI (ANSI 156.2-1999) is the most complete;
· Australian Standard AS (AS4145.2-1993) is the most stringent “trade barrierâ€;
· Japanese standard JIS (JISA1510-1995) is more relaxed.
The one-way comparison for the European standard and the American standard is as follows.
1. American National Standard: ANSI 156.4, American Underwriters Laboratories UL10C.
· The number of standard opening times: ≥ 2 million times;
· The number of secondary standards open: ≥ 1 million times;
· The number of three levels of standard opening: ≥ 500,000 times.
2, 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.
For a large commercial building, the number of doors 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.
Selection principle
In summary, when selecting intelligent building electrical locks and hardware solutions, it is recommended to follow the following basic selection principles:
The location used and its importance should be considered for use in gates, hall doors, rooms, bathrooms or passages in order to select the product that suits the desired function;
The environment and conditions used must consider the advantages and disadvantages 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 people who are frequently used and consider whether there are elderly people, children or people with disabilities;
Considering the coordination with the decorative environment, it should be considered that the coordination and matching with the decorative environment should be consistent;
Introduction to the five major standards for common locks
In the process of electric lock and hardware selection, different standards are often encountered. At present, the commonly used standards are European standard and American standard. The current standards in the world of locks and hardware mainly include the following:
