Door Lock and Door Hinge Endurance Test Bench

This test bench is used for the door lock opening and closing durability test of the front door and rear door of the vehicle (including the durability test of the lock device itself in the high and low temperature box), the number of door lock failures during the test; By designating the operation force during the test, it can also be used for the car side door hinge vertical stiffness test, door opening strength test, and door sink and hinge deformation simulation to judge the qualification of products; It provides accurate testing parameters for the development, designing and research of the products.

Test Items

Various car locks test:

· The test bench is suitable for testing the durability of various cars’ side door locks (front, rear, left, right), luggage compartment lock, engine hood lock, and side sliding door real car door lock.

· Side door lock durability test includes opening, closing, outside opening, inside opening, child lock. Luggage compartment lock test includes internal opening, external opening and other testing action. Engine hood lock test includes opening and closing actions. Side sliding door real car door push and pull, door lock opening and closing. All the above various locks’ action can be arbitrarily set.

· Check the normal opening of the door lock and the number of control device failures.

· Simulate the door lock state of the real car. Simultaneously achieve the durability test of four door locks (two side door locks, one luggage compartment lock and one engine hood lock.)

· Simulate the door hinge state of the real car. Simultaneously achieve the durability test of four door lock hinges (two side door hinges, one luggage compartment hinge and one engine hood hinge)

FAQ

(1)What is a Door Lock and Door Hinge Endurance Test Bench used for?

A Door Lock and Door Hinge Endurance Test Bench is used to evaluate the service life and mechanical durability of door hardware components through repeated operation cycles. The equipment simulates actual usage conditions such as door opening, closing, locking, and unlocking to assess whether door locks, hinges, latches, and related components can maintain normal function after long-term operation.

(2)How is the durability of a door lock tested?

Door lock durability is typically evaluated by repeatedly performing locking and unlocking operations for a specified number of cycles. During the test, the equipment monitors whether the lock mechanism continues to operate correctly and whether problems such as failure to lock, unlocking difficulty, abnormal wear, or component damage occur. The test method and cycle requirements depend on the door lock type and applicable standard.

(3)How do you test the service life of a door hinge?

Door hinge life testing is performed by repeatedly opening and closing the door assembly to simulate daily use. The test evaluates hinge performance after continuous operation, including smooth movement, structural wear, looseness, deformation, and any functional failure. This helps manufacturers verify whether hinge designs and materials meet expected durability requirements.

(4)Which standards are related to door lock and hinge endurance testing?

Door hardware endurance testing is usually performed according to the requirements of the specific product category and market. Commonly referenced standards include EN 12209 for mechanically operated locks and latches, EN 1935 for single-axis hinges, and ANSI/BHMA A156 series for architectural hardware performance requirements. The applicable standard depends on the door hardware type and certification requirements.

(5)Can one Door Lock and Door Hinge Endurance Test Bench test different types of door hardware?

The testing capability depends on the equipment design and fixture configuration. Many endurance test benches can be adapted for different door hardware components by using adjustable fixtures or customized mounting systems. Before testing, users should confirm the product type, installation method, operating movement, and required test conditions to ensure proper setup.

(6)Why is cycle testing important for door hardware manufacturers?

Door hardware is used repeatedly throughout its service life, and failures may not appear during basic inspection. Cycle testing helps manufacturers identify potential issues such as premature wear, loose components, mechanism failure, or reduced operating performance. The test data can be used for product improvement, production quality control, and verification before market release.

(7)What factors affect door lock and hinge durability test results?

Test results can be influenced by factors such as hardware material, product design, installation method, operating force, test frequency, load conditions, and environmental conditions. To obtain meaningful results, manufacturers need to maintain consistent test conditions and follow the requirements of the selected testing method.

(8)What should be considered when choosing a Door Lock and Door Hinge Endurance Test Bench?

When selecting an endurance test bench, users should consider the types of hardware to be tested, required test standards, fixture flexibility, cycle control capability, data recording requirements, and future testing needs. Door manufacturers and hardware suppliers should choose equipment that matches their actual products and quality control procedures rather than focusing only on basic machine specifications.
