TLJ locks achieve UKCA certification

We're delighted to announce that UKCA (UK Conformity Assessed) marking can now be used on all TLJ locks cases and lever sets.

It replaces the old 'CE' marking which became obsolete in the UK following Brexit, though it is a like-for-like replacement in all important respects. Thorough testing of TLJ's battery powered locksets was carried out by approved inspection, testing and certification company Warringtonfire Limited. Certain UKCA adaptations for Northern Ireland were included in the testing, which we also achieved. The certification is valid until the end of March 2025.

Some performance highlights during testing include:
  • Achieved 100,000 lock operating cycles with a 25N side load on the latch, to simulate the mechanical stress of multiple door closures
  • Exceeded 30 and 60 min fire tests. Often overlooked, but the door set must be tested/burnt from both sides of the door, sustaining at least 30 minutes in both tests
  • Included factory production control and sampled specimen audit. Not only is the manufacturing process audited, but the hardware tested in the mechanical cycle testing is sampled. This means that the items are chosen at random, directly at the factory by the notified body. This ensures the tests are not manipulated and that the items tested are a true resemblance of those installed in the field
  • For the mechanical cycle testing, it's worth noting that the minimum pass requirement is 50,000 cycles with no side load. The performance shown throughout this test reveals just how far ahead of mandated requirements are TLJ's products. Double the number of openings, with a side load, means it's unlikely any level of usage will ever reach the real-world operational limits of a TLJ lock.
About UKCA marking

The UKCA marking is a new UK product marking that is used for goods being placed on the market in Great Britain (England, Wales and Scotland). It covers most goods which previously required the CE marking, known as ‘new approach’ goods.

The UKCA marking came into effect on 1 January 2021. However, to allow businesses time to adjust to the new requirements, firms will still be able to use the CE marking until 1 January 2023 in most cases.

The UKCA marking alone cannot be used for goods placed on the Northern Ireland market; additional testing must be undertaken in this case.
