The doors were approved by certifire, they must have a copy of the original test evidence.

The issue for the many building operators that have Fire Doors manufactured by Leaderflush Shapland is that they must still maintain those doors to meet fire safety regulations.  Clearly these doors will have been installed some years ago and as this manufacturer is no longer in business the certification and data sheets for the doors are no longer available from the website of the third party certification company. 

However where those records are archived, the data sheet can be referenced to assist with inspections, maintenance and repairs. For example certificate data sheet CF113 (see excerpt attached) from the year 2007 is clearly no longer valid but the door in question would have been manufactured and installed of its time, therefore this is the correct document to use for maintenance and repair purposes - so there's your proof!

What Sean says would be correct in a scenario where a door supplier was attempting to market for sale new fire doors using that out of date certification, but clearly not where somebody is carrying out maintenance and repairs to an old fire door that bears the matching certification label!

This is really amazing Neil, so when inspecting a Leaderflush Shapland door would i hold that door to those 2007 standards or the current standards? and what about 60 minute Leaderflush doors? as the data sheet doesn`t mention them or any potential ironmongery. 

For a certificated fire door made in say 2007, the only certification you can reliably use would be the certification issued at that time.  This is because of the possibility that that certification published later may refer to a door design that has been revised in some way and therefore different to the original door. 

Obviously, the certification refers to a particular design of door and can only be applied as such. The same manufacturer may have many different door designs.

Hello, Can you clarify for me what could have cause the gap from 3/4 mm to have increased around some part of the door frame to become not compliant anymore ?  all the doors in the building had this exact problem.  (all doors were not damaged, not modified, or anything else done by owners) this is a new building and everything was fine until June 2025 fire door assessment. previous years all was perfect.

Thank you

 

What is the difference in measurements? If its only small (1 to 2 mm) its probably

1.      Operator eyesight

2.      Different operator

3.      Different expansion rates (walls, doors, wood)

4.      Movement of the building
