Test Method A is applicable to low <span style=\"font-style:italic;font-weight:normal\">n<\/span>th order reactions. Test Methods B and C are applicable to accelerating reactions such as thermoset curing or pyrotechnic reactions and crystallization transformations in the temperature range from 300 to 900 K (nominally 30 to 630\u00b0C). This test method is applicable only to these types of exothermic reactions when the thermal curves do not exhibit shoulders, double peaks, discontinuities or shifts in baseline.<\/p>\n<\/p><\/div>\n<div class=\"SectionLevel2\">\n<p class=\"subsec1\">1.2&nbsp;Test Methods D and E also determines the activation energy of a set of time-to-event and isothermal temperature data generated by this or other procedures<\/p>\n<\/p><\/div>\n<div class=\"SectionLevel2\">\n<p class=\"subsec1\">1.3&nbsp;The values stated in SI units are to be regarded as standard.
