I have encountered ITE with UL, CSA and TUV certification that uses wood as
the interior frame and enclosure. One must demonstrate that it is impossible
for a fire to start and to invoke clause 1.4.1 of IEC 950.

Never saw wood in ITE equipment . . . other than in the 'Pirates of
Silicon Valley' movie. The
first Apple was built out of wood. I don't suppose we'd find too
much of that these days.
Seems to me that there should also be a spec for 'long term'
enclosure stability
based on 'termite resistance'!
Sorry . . . couldn't resist.

Dear All,
There is a UL 1950 "PAG" stating that hardwood or presswood of
"substantial" construction is accepted without flammability tests
per Annex
A for products covered under UL1950.
The questions are:
1. What thickness is considered "substatntial"?
2. What other types of wood are considered acceptable without
flammability
tests?
3. What do European Test Houses require from the flammability
standpoint of
wooden enclosures or internal wooden materials?
Thanks
