[ASTME2019]
self-heating or self-heating
spontaneobs heating or self heating in the space between two single-ion conductors noun a thermal reaction of a material resulting in a temperature above that of its surroundings due to a slow or incomplete reaction. [ASTM E 771]
spontancous heating temperature or self-heating temperature noun the lowest temperature at which spontaneous heating or self-heating occurs under specific experimental conditions. This temperature is the autoignition temperature of the material in the initial stage of the reaction.
【ASTM E 771]
strikingsurface
noun a hard, smooth, rounded bottom surface of an intermediate tool used to test a specimen. [ASTM E 680]
GB/T 22233-2008
temperature rise
temperature rise
noun the difference between T and the initial set temperature of the cooked board. LASTME2021
thresholdtemperature noun - the temperature at which the exothermic reaction begins when the T-T curve declines, and the sample begins to spontaneously generate heat. [ASTM E 476]
thermal-runaway time
time-to-thermal-runaway
noun - the time required for an exothermic reaction to reach the thermal breakdown point in an insulated container (i.e., no heat exchange with the environment). [ASTME1231]
noun the highest temperature measured during the test. ASTM E 2021]
uriconfined test
unconfined test
noun - a test in which the test sample is placed directly on the platform and is not constrained by the near boundary. LASTM E 680]
Upper limit off flammability or upper flammable limit cUFL? Noun: The maximum concentration of a flammable material that can cause the reaction mixture of a susceptible material and a gaseous oxidant to produce fire under specific laboratory conditions.
