If someone specifies -
"manufacture and delivery of 4 no doors in "C" class fr material and including all running gear"
in respect of bi-fold doors. What makes the doors conform to the "C" class fire retardent standard? I assume that itis the finish that is applied, and the standard/quality of glass? I assume that metal running gear would conform?

As I understand it'll either be built to a BRS spec or to a spec which has been tested and shown to conform. What makes it qualify may be down to materials, design, finishes or various combinations of these. The supplier should be able to tell you, after all he is legally committing himself to supplying goods to the standard.

Not sure I've heard of this one.
Heard of 0 class, which is non combustinle paint.
Whatever it is don't say yes until you're sure.
If you are making the doors and supplying running gear, glass, ironmongery and paint from different sources , they must al be up to standard( think it's BWF).
You're company holds responsibility.

basic rule is that they have to specify what they mean by "c" since they are using it as a material clause, they must inform you of all the details therof. next, you will have to see whether you will be able to comply, and also whether the supplier of the other bits meets class "c" too frankly until they tell you, don't take the job on  paul  |

Looking at Hendersons site, just because the main part of the door gear is metal does not make it comply with fire regs. They do a special FR kit for their Marathon runners that will self close in the event of fire and has extra seals around the track as well as intumescent strips.
The only ref I could find to class C was on a foriegn site where it refered to self closing. Boards are generally class 0 or 1 spread of fire.

It looks like it is probably a UL (Underwriter's Laboratory = Yank) classification.

Had another look - it's the glass I think I think that refers to impact resistance not fire resistance. Jason |

any helpThe class c part seems to refer to the position of the doors. although this is american, im sure our regs will be similar. a phone call to your local BCO could be helpful. You will probably find the doors, their finish, glass and sliding gear all have to be fire rated. Cheers, Gazza.
