Fire tests for B-class doors: UK21/F008
Adopted EU recommendation FIRE-025. UK approved recommendation on the testing of B-class doors.
Question
The question concerns approved B-class bulkhead as supporting construction for B-class door and approved B-class ceilings incorporating fittings.
Integrity failure may occur along one of the joints in the approved B-class bulkhead. Shall this integrity failure be considered a failure of the door construction as well?
The same question may apply to approved B-class ceiling incorporating fittings.
Recommendation
Bulkheads
As long as the failure in the joints of the B-class bulkhead does not occur in the area immediately surrounding the doorframe, the integrity failure shall not be considered a failure of the door construction.
Ceilings
In case of ceiling incorporating fittings, the failure of joints between ceiling and fittings is to be considered a failure of the integrity of the B-class division when incorporating such fittings, not a failure of the basic performance of the approved B-class ceiling itself as tested when no fittings are installed.
In case of failure the following actions shall be taken by the UK approved body:
- Inform the Approved Body issuing the production conformity certificate
- Inform the manufacturer of the supporting construction
- Inform the administration
