Limitations may be indicated by curves departing from a straight line (see 11.2) or the isothermal aging test not closely agreeing with the results predicted by the calculated kinetic values. In particular, this test method is not applicable to reactions that are partially inhibited. The technique may not work with reactions that include simultaneous or consecutive reaction steps. This test method may not apply to materials that undergo phase transitions if the reaction rate is significant at the transition temperature.<\/p>\n<p id=\"s00005\">1.4 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.<\/p>\n<p id=\"s00006\">1.5 <span class=\"italic\">This standard may involve hazardous materials, operations, and equipment.
