That's really what one would expect. BAS has already illustrated the lunacy of taking "non-combustible" completely literally.I can't find that term in 61439-1 or -3. I have seen, in other standards, the term "essentially non-combustible" used, which looks like an attempt to address the fact that just about anything would combust if dropped onto the surface of the sun.Is it therefore your view that the Standards do define what is regarded as 'non-combustible'? Do they actually use the term 'non-combustible'?
That sound very reasonable. So, if one takes that view, then what of the second question I asked - what meaning or sense can you make out of "shall comply with BS EN 614393 and shall be constructed out of non-combustible material"???If we regard the term as meaning "non-combustible under the expected conditions of use, then yes, I would say that 61439 has addressed that by the tests referred to in my extract.
