What are the differences between American door lock standards and European door lock standards?

The American door lock standard is different from the European door lock standard mainly because of the differences in the building codes and regulations in the two regions. In the United States, the Underwriters Laboratories (UL) standard is used to certify door locks, while in Europe, the European Norm (EN) standard is used.


The UL standard focuses primarily on security and safety, ensuring that door locks can withstand various forms of impact, weathering, and tampering. The UL standard also regulates the durability and longevity of door locks, ensuring that they can withstand everyday wear and tear.


The EN standard, on the other hand, has a broader scope and covers various aspects of door locks, including their performance, functionality, and safety. In addition to security, it also focuses on issues such as fire safety, accessibility, and environmental sustainability.


Overall, while both standards aim to ensure the safety and security of door locks, they have different priorities and focuses, reflecting the different building codes and regulations prevalent in the regions they serve.


Here are the differences between the door lock test standard of UL and the door lock test standard of EN:

1. Testing Methods: UL uses a static load test, which involves applying a constant force to the lock until it fails. EN, on the other hand, uses a dynamic load test, which involves applying a series of impacts to the lock to simulate the force of a physical attack.

2. Test Criteria: UL tests for durability and strength, while EN tests for security against physical attack. UL requires the lock to withstand a certain amount of force without breaking, while EN requires the lock to resist a variety of attacks, including drilling, picking, and bumping.

3. Certification: UL certification is primarily focused on the safety and performance of the lock, while EN certification is focused on the security of the lock against physical attack. UL certification is required for locks used in North America, while EN certification is required for locks used in Europe.

4. Standards: UL is a US-based organization that sets standards for safety and performance, while EN is a European standard that sets standards for security and performance.

5. Testing Equipment: UL uses specialized testing equipment to simulate the forces that a lock may experience during use, while EN uses a variety of tools and techniques to simulate the different types of attacks that a lock may face.
