 【摘要】  This standard deals with dry heat tests applicable both to heat-dissipating and non heatdissipatingspecimens. For non heat-dissipating specimens, Tests Bb and Bd do not deviateessentially from earlier issues.The object of the dry heat test is limited to the determination of the ability of components,equipment or other articles to be used, transported or stored at high temperature.These dry heat tests do not enable the ability of specimens to withstand or operate during thetemperature variations to be assessed. In this case, it would be necessary to use IEC 60068-2-14 Test N: Change of temperature.The dry heat tests are subdivided as follows:Dry heat test for non heat-dissipating specimens– with gradual change of temperature, Bb.Dry heat tests for heat-dissipating specimens– with gradual change of temperature, Bd;– with gradual change of temperature, specimen powered throughout, Be.The procedures given in this standard are normally intended for specimens that achievetemperature stability during the performance of the test procedure.
