I'm having one of those days - you know when you think you know the answer but doubt creeps in? As far as I am concerned fire resisting glazing must be identified by an acid etched trade name and BS476 part 22. If either is missing the glazing is not fire resisting and must be replaced. I came across a brand new FR door today with etched marking "WOODS BS 6206 A TOUGH" in one corner and as far as I am concerned this is not to be accepted. Am I right?

I seem to recall Building Regulations require kitemark and BS visible at one corner of plain glass. Does Georgian Wired Polished Plate not also qualify as acceptable though?

SW is quite right; I'd suggest you check the Pilkington site for more information on fire resisting glass. http://www.pilkington.co...reprotection/default.htm BS 6206 defines the term breaks safely by reference to the outcome of the impact test. • Toughened glass breaks safely if the glass breaks into sufficiently small fragments after impact, I.e. if the weight of the 10 largest crack-free particles weigh less than the equivalent of 6500mm2 of the original sample. • Laminated glass, wired glass and filmed glass are deemed to have broken safely if, after the impact, any glass fragments which fall off are not too large (defined in BS 6206) and it is not possible to pass a 75mm diameter sphere through any opening formed in the glass. Other glass products used for glazing, e.g. annealed (ordinary) glass, or heat strengthened glass, do not break safely, and can only pass the requirements if they do not break in the test. The test requires either a standard size or the maximum size of pane available if this is smaller than the standard size. The test specimen size is 865x1930mm. A safety glass only complies with BS6206 if it is marked as doing so. The standard requires that all installed panels shall be marked to include the following: • An identifiable name or trademark or other mark capable of identification through a suitable source • The type of material • The number of the British Standard, i.e. BS 6206 • The classification relating to impact test behaviour (Class A, B or C). These marks shall be permanent and applied before installation in a position to remain visible after installation. All suppliers of final cut sizes of safety glass should mark the glass in accordance with BS 6206. BS 6206 has now been superseded and replaced by EN 12600. Marking of safety glass has now changed. Please see BS 6262 Part 4 for requirements or contact the Technical Advisory Service on (01744) 69 2000 for guidance.

Chris, we could start a whole new thread about fire doors being installed incorrectly; we have some "not so expert" installers here who have created a huge problem by them and their supervisors not sticking to the specification. Fortunatley not my area of responsibilty, but a minefield nonetheless. It's Friday afternoon and a bank holiday weekend ..... Yipee :-) Have a good one all.

That's a little underhand isn't it? The FRA & completion certificate are completely separate items and for BC to demand to see a RP's FRA seems dodgy. My initial thoughts are that BC haven't a right to see/demand it. Is this happening elsewhere?

The GGF have some decent publications also. http://www.ggf.org.uk/publications
