There are rules at home and trade marks at home. As an important category of hardware, what are the standards? The selection of electric locks and hardware often meets different standards

At present, the commonly used standards are European standards and American standards. At present, there are mainly the following standards in locks and hardware around the world:

The one-way comparison between European Standard and American Standard is as follows:

1. American national standard: ANSI156.4, UL 10C.

Level I standard opening times: ≥ 2 million times;

Secondary standard opening times: ≥ 1 million times;

Level III standard opening times: ≥ 500000 times.

2. European standards CE: EN1154 (performance test) and EN1634 (fire test),

Index of opening times: ≥ 500000 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 American standard electric locks or hardware products are more expensive in 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 scheme for doors with different parts and different use requirements to ensure a long service life and the lowest maintenance amount in the future is a very complex and tedious work. A set of the best hardware lock overall solution should be a unity of convenience, security and durability

To sum up, when selecting the electric lock and hardware scheme of intelligent buildings, it is recommended to follow the following basic selection principles: the place used and its importance should be considered to be used on the gate, hall door, room, bathroom or passageway, so as to select the product suitable for the required function; The use environment and conditions shall consider the advantages and disadvantages of the use environment, such as the use frequency, whether it is a fire door, the structure, weight, thickness, etc. of the door; Consider the situation of frequently used personnel and whether there are elderly, children or disabled persons; The coordination with the decoration environment shall be considered, and the coordination and matching with the decoration environment shall be consistent. All living enterprises should be people-oriented and make green and healthy products suitable for our living.
