Standards and accreditation

UKAS schedule 28212, ISO/IEC 17025:2017
The fresh UKAS result links issue 004 dated 9 April 2026, limited to testing at the exact Preston address. The two building-hardware product rows and listed methods define this guide’s accreditation scope.
Controlled door-closing devices
BS EN 1154:1997 + A1:2002/AC:2006 is listed for operation at temperature extremes and mechanical performance/durability. The Single Action Only product restriction applies.
Electrically powered hold-open devices
The mechanical performance/durability row lists BS EN 1155:1997 + A1:2002/ AC 2003 / AC2 2003 / AC3 2006 for electrically powered hold-open devices for swing doors. The listed amendments and corrigenda are retained as written in the schedule.

What to confirm with the facility

  • UKAS and BWF identify Preston, while the owner homepage and contact footer say Wigan. This guide follows the exact current Preston register and schedule. The owner wording does not establish a second accredited site or move Preston testing to Wigan.
  • Controlled door closers are restricted to Single Action Only. Electrically powered hold-open devices for swing doors have a separate mechanical-performance/durability row. The schedule does not establish testing of every lock, hinge, door, window or roller shutter, or a fire-resistance service.
  • The owner’s wider corrosion, bespoke, R&D and rig-hire descriptions are general service context. They are not verified Preston accredited methods or equipment in this guide. No numerical temperature range, cycle rating, rig model, specimen envelope or hire capacity was verified.
  • The schedule is issue 004 dated 9 April 2026, with PDF creation and modification metadata on 21 April 2026. Confirm the current relevant product row, requested edition and report accreditation status before arranging tests.
  • Agree product drawings and configuration, sample preparation and quantity, delivery, test sequence and conditions, acceptance criteria, witness requirements, report content, costs and programme with the laboratory.

  3. Northwest Labs homepage and wider service context

    Northwest Labs · Reviewed

    The owner describes mechanical door-hardware testing and invites enquiries. Its footer says Wigan and mentions doors, windows and roller shutters, while the current schedule and BWF entry identify Preston. Its wider durability, corrosion, bespoke, R&D and rig-hire menu is not transferred to this Preston guide. Repeated 15 February 2024 blog dates are not homepage publication or modification dates. No homepage date metadata was verified.

  4. Northwest Labs general contact page

    Northwest Labs · Reviewed

    The page publishes 01772 348185, displays Info@northwestlabs.co.uk with a lowercase info@northwestlabs.co.uk mailto target, and offers an enquiry form. This is a general organisation route. Its footer repeats Wigan and broader product wording, without a Preston street address. The exact Preston address and primary email come from schedule 28212. No publication or modification date was verified.
