Description / Abstract:
These test methods cover procedures for determining whether a
material does or does not flash at a specified temperature or for
determining the lowest finite temperature at which a material does
flash when using a small scale closedcup apparatus.2 The test
methods are applicable to paints, enamels, lacquers, varnishes, and
related products having a flash point between 0 and 110°C (32 and
230°F) and viscosity lower than 150 St at 25°C (77°F).
NOTE 1—Tests at higher or lower temperatures are possible.
NOTE 2—More viscous materials may be tested in accordance with
Annex A4.
NOTE 3—Organic peroxides may be tested in accordance with Annex
A5, which describes the applicable safety precautions.
NOTE 4—The U.S. Department of Labor (OSHA, Hazard
Communications), the U.S. Department of Transportation (RSPA), and
the U.S. Environmental Protection Agency (EPA) have specified Test
Methods D3278 as one of several acceptable methods for the
determination of flash point of liquids in their regulations.
NOTE 5—These test methods are similar to International Standards
ISO 3679 and ISO 3680.
The values stated in SI units are to be regarded as the
standard. The values given in parentheses are for information
only.
This standard should be used to measure and describe the
response of materials, products, or assemblies to heat and flame
under controlled conditions and should not be used to describe or
appraise the fire-hazard or fire-risk of materials, products, or
assemblies under actual fire conditions. However, results of the
test may be used as elements of a fire-hazard or a fire-risk
assessment which takes into account all of the factors which are
pertinent to an assessment of the fire hazard or fire risk of a
particular end use.
This standard does not purport to address all of the safety
concerns, if any, associated with its use. It is the responsibility
of the user of this standard to establish appropriate safety and
health practices and determine the applicability of regulatory
limitations prior to use. For specific hazard statements, see
8.1 and 11.2.
