(Test Method)Standard Test Methods for Flash Point by Small Scale Closed Cup Tester
Standard Test Methods for Flash Point by Small Scale Closed Cup Tester
SIGNIFICANCE AND USE
Flash point measures the response of the specimen of the sample to heat and flame under controlled laboratory conditions. It is only one of a number of properties that must be considered in assessing the overall flammability hazard of a material.
Flash point is used in shipping and safety regulations to define flammable and combustible materials and classify them. One should consult the particular regulation involved for precise definitions of these classes.
Flash point can indicate the possible presence of highly volatile and flammable materials in a relatively nonvolatile or nonflammable material.
Requires smaller sample (2 to 4 mL) and therefore reduced test time (1 to 2 min).
SCOPE
1.1 These test methods cover procedures for the determination of the flash point by a small scale closed tester. The procedures may be used to determine the actual flash point temperature of a sample or whether a product will or will not flash at a specified temperature (flash/no flash). When used in conjunction with an electronic thermal flash detector, these test methods are also suitable for flash point tests on fatty acid methyl esters (FAME).

1.3 This standard should be used to measure and describe the properties of materials, products, or assemblies in response to heat and flame under controlled laboratory 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 this test may be used as elements of a fire risk assessment which takes into account all of the factors which are pertinent to an assessment of the fire hazard of a particular end useThis 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. Warning statements appear throughout. See also the Material Safety Data Sheets for the product being tested.

INTRODUCTION
The flash point method is generally used for testing a sample at a specific temperature. At a set
temperature, the specimen being tested and the air–vapor mixture above it are close to thermal
equilibrium. Test methods for other flash point equipment operated at a specific temperature are
described in Test Method D3941.
Flash point values are a function of the apparatus design, the condition of the apparatus used, and
the operational procedure carried out. Flash point can therefore only be defined in terms of a standard
test method, and no general valid correlation can be guaranteed between results obtained by different
test methods, or with test apparatus different from that specified.
