I am familiar with how products are tested. But I don't know how that is interpreted by building control. I'm dont know about non ceiling light questions! I was interested in the original thread, as the inspector was asking for an unknown test. So they may have some policy or interpretation...
Not sure how I unlock my profile. Paying around £10K per ceiling type test and you get a test certificate for that type. So test the 30min ceiling and you get lights rated for 30mins. You need to test, 30, 60, and 90 to pass on the certification. I don't know who is liable if a 90minute light...
Sorry, that's from my research. We are about to invest in fire testing some products. Investing in a 30minute ceiling test probably covers more installation types, but everyone thinks 90 minutes is better, but 3 layer ceilings are less common. Exova is one of the main UK test bodies.
I haven't found a test house that would agree with this. Sorry. They would only sign a document to say a 90minute product is suitable for a 90min ceiling. not a 90min product to a 30min ceiling. -If it hasnt been tested in that scenario.
This is where the miss-understanding comes from as the tests are very specific. There are many ceiling types, but the main ones tested are 30minute (1 FR plasterboard layer),
60minute (2 FR plasterboard layers), 90minute (3 FR plasterboard layers).
If a 90 minute rated luminaire is fitted to a...
Wow, thanks for the detailed reply. It still feels odd he can compell you to do extra work without the test standard to refer to. - Just making it up. I've been doing a lot of research on fire ratings, and I dont think it's well known how to interpret them. There is no fire test for lights! -...
Do you mind sharing what the result with the building inspector was? I think he was asking for certifcates for a test that Doesn't exist. Did he ask for any british standard
It's a good idea, that I think will come out soon from the huge manufacturers. The tooling & testing cost is fairly massive. I looked at it, but out of our range at the moment. Probably a 2 year development, so some may be launching soon.
I'll make a sponsored post soon, and write about them. - Better is a difficult term, we have chosen a market and quality standard and designed products to hopefully suit it. The job is always to get a better balance between the competing factors (& compromises) of price, specification...
This is the reason why it's quite nerveracking for me to post here! No messing around. And probably why not many companies invite fairly brutal feedback.
Thanks Dan, fair enough. Promo thread is the way to go I think. This wasn't in the marketing plan, to tie up forums. - Rather a place where I could give back some behind the scenes stuff that isnt very salesy. The challenges that we came up against, answering questions etc.
