Table 3 - Temperature limits
Key words:

Decision taken by
ETF3 and confirmed
by CTL at its 38th
meeting, in Toronto
Question:
How can the requirements of this clause be used for parts in contact with liquids. Where can
the figures for Fire Point be obtained?
Decision and Explanation
This requirement should only be applied where a hazard may arise.
Figures for fire point are available in ANSI/NFPA 497-1997, published by the National Fire
Protection Association, Quincy, Massachusetts, USA.
Table 2-1 of NFPA 497 identifies flash points, autoignition temperatures
(fire points), lower and upper flammable limits (in %), vapor densities,
vapor pressures, minimum ignition energies, minimum ignition current ratios,
and maximum experimental safe gaps of approximately 225 common liquids and
gases.
