Legislation, Compatibility and Compliance
Aim: To achieve effective fire protection of buildings, contents and occupants.
Critical Responsibility: TDSL believe that
- Compatibility (meets or exceeds requirement specification) and
- Compliance (meets or exceeds legislative framework and standards)
are critical responsibilities for all concerned.
Essential Components Are:
- Correct specification
- All components work together
- Critical ironmongery effective at both FD30 and FD60 to prove suitability and possibly FD90 and FD120
- Correct installation
- Correct maintenance
All are governed by
- Building Regulations and
- British Standards (various)
Legislation: All TDSL doorsets:
- Conform to the fire performance evidence appropriate to their use (FD30, FD60, FD90 and FD120 rating) and
- Carry third-party certification that TDSL doors and critical ironmongery meet the legislative requirements of BS 476 Part 22. 1987.
(Details of all tests conducted are available on request. Certificates of conformity to standards are available to download as .pdf files.)
Laboratory tests determine the fire resistance (smoke, fire, heat), acoustic performance and emission protection (x-rays) of elements of construction when subjected to defined heating and pressure, sound and radiation conditions.
- How The Third Party Tests Are Performed

How The Third Party Tests Are Performed
The methods are to BS approved procedures and conditions and were introduced by innovative market leader TDSL, ahead of building regulation requirement changes.
Testing provides a means of quantifying the ability of elements to withstand exposure to high temperatures, by setting criteria by which the load-bearing capacity, the fire containment (integrity) and the thermal transmittance (insulation) functions can be measured.
A representative sample of the element is exposed to a specified regime of heating and the performance of the test sample is monitored on the basis of criteria described in the standard.
Tests are also carried out on the whole assembly including the frame and fittings. Fire resistance of the test element is expressed as the time for which appropriate criteria have been satisfied. The times obtained are a measure of the adequacy of the construction in a fire but have no direct relationship with the duration of a real fire.

Note, diagrams are indicative of structure for easier client discussions and help in the requirements specification as you consider all the elements of your project. They are not to scale. TDSL's policy is to provide full drawings when required on appointment as supplier/contractor and order placed and look forward to answering your specific questions. TDSL will add more to meet customer demand, and welcome your suggestions.

Service Life and Durability
A rigorous undertaking
Doors often need to perform a number of functions in their service life. They may need to be fire resistant as well as an effective means of providing access between areas of a building.
In hospital wards and corridors, doors get a heavy, frequent use. They can be subject to more physical abuse, so it is vital that they are durable and able to continue to perform their everyday function….as well as maintain their fire resistance and other specialist functions.
Following consultation with Chiltern Dynamics, TDSL undertook a series of full size rigorous tests based on Chiltern's 'Classification for Service Life' Test Programme to assess doorset durability performance for all categories up to severe duty. Performance against the test's characteristics allows classification terms of the doorset's duty relating to the sort of wear and tear typical of cross-corridor locations in hospitals, schools and large offices, with severe being the most demanding classification. The results and information gained from this testing programme will enable facilities management teams to evaluate, with real certainty, full service life costing's for doorset assemblies.

Timbmet Doors - Rigorous Fire Test Evidence
In 1993, soon after Timbmet Doors was formed, there was confusion, ignorance and negligence to fire safety in fire door products across the business. We were so concerned, that we began testing, for ourselves, the products that we were sourcing.
We realised particularly that manufacturers' fire test evidence could easily be invalidated when incorrect glazing, ironmongery, leaf re-sizing, frame specification and intumescent products become part of the equation. Existing manufacturers' evidence needed to be extended.
As a distributor of products that could be effected in this way, we felt we had an additional and very serious responsibility to our customers and a desire, even in those early days, to drive up standards. Through Chiltern International Fire, we very quickly created a bank of Timbmet Doors generated fire test reports and global assessments.
We embraced the idea of independent third-party certification and believe we were one step ahead of other suppliers when the UK Government amended Building Regulations - Approved Document B to Include its recommendation that a third-party certified fire door assembly should always be used.
Today, the list of Timbmet Door Solutions products with independent third-party certification is comprehensive and continuously growing.
