標準簡介

IEC 60068-2-2:2007 Deals with dry heat tests applicable both to heat-dissipating and non heat-dissipating specimens. For non heat-dissipating specimens, Tests Bb and Bd do not deviate essentially 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 the temperature 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 achieve temperature stability during the performance of the test procedure. The main changes from the previous edition are as follows: Tests Ba and Bc have been deleted since they were more severe tests than Test Nb, IEC 60068-2-14: Change of temperature. Secondly it was considered justified to delete the 3 % value on the temperature difference between the chamber air and the wall temperatures. Thirdly it is proposed that the test specimen be powered throughout the test where required; and, finally, the annexes have been removed. It has the status of a horizontal standard in accordance with IEC Guide 104
