Deadbolt & handle breaking strength test

To assure better security and locking strength, product undergoes dead bolt's lateral pressure test, pushing test and handle's static vertical load test, tension load test with a higher standard than Korean Standard. Table below shows the result,

Test	KS / KC standard	Company standard
Mortise lateral pressure/pushing	2,451N / 1,470N	2,940N / 1,764N
Dead Bolt lateral pressure	2,451N	2,940N
Dead Bolt Pushing test	1,470N	1,764N
Handle vertical / tension	2,451N each	2,940 N each

External shock on product

To assure the product durability on damage or external shock, the below table shows the result of freefalling test under KS Standard

Test	KS /KC standard	Company standard
Freefall test	Free fall 540g steel ball from 1.3m high, shock outside of the product. the product should not malfunction.	Same standard with KS / KC standard but test on all 5 sides of the door lock, and no malfunctioning should happen.

Opening/shutting lifespan

The below table shows the results of high frequent opening and closing lifespan.

Test	KS /KC standard	Company standard
Button key test	20,000 times	120,000 times
RF card test	40,000 times	120,000 times
Automating open/shut	40,000 times	120,000 times

High temp, high humidity and low temp test

Tested and assured to use the product in hot and high humid place, also in cold places

Test
High temp	In 60-+ 3 degrees, leave it for 48 hours and should function perfectly in 5 min.
High humid	95%-+ 2/-3 condition, leave for 48 hours and should function perfectly in 5 min.
Low temp	-25 -+ 2 degrees, leave for 48 hours and should function perfectly in 5 min.

Salt spray test/corrosion test

Tested and assured durability, resistance to corrosion of the products

Testing
Saline water concentration	5.0% -+ 0.5%
Testing temp	35 -+ 2 degrees Celsius
Number of Sample	More than 2
Testing time	72 hr.
Sprayed capacity	Sprayed pressure 0.7~1.8kg/cm^2, 1 min in every 10 min.

Waterproof test

The products are waterproof. Product functions perfectly on the outside, in heavy rain area. (not KS standard test)

Condensation test

Tested and assured working of the product when outside/inside temperature differs a lot in hot summer or winter. (not KS standard test)

Secure test in case of fire

If there is a fire inside, the door will be opened automatically for people inside to evacuate quickly. KS / KC standard: it will detect fire's high tem (65 -+ 5), door lock will get automatically opened

Fireproof technology

On fireproof door where digital door lock is installed, no fire should go outside not to be spread. All door locks are tested according to KC standard (in 1000 degree, non-thermal barrier, no fire should be seen from outside for more than 10 sec when fire was shot at for an hour)
