Foreword

GB/T 20159 "between the environmental conditions classification Classification of environmental conditions and environmental tests Relationship and Conversion Guide" is currently divided into the following if Cadre points. --- GB/T 20159.1 Classification of environmental conditions Environmental conditions of the relationship between the classification and environmental testing and conversion guidelines storage; --- GB/T 20159.2 environmental conditions and the relationship between the free conversion guide transportation Classification of environmental conditions and environmental tests; --- GB/T 20159.3 between environmental conditions classification Classification of environmental conditions and environmental tests have climate relationship and Conversion Guide Stationary use protective properties; --- GB/T 20159.4 Classification of environmental conditions between the Classification of environmental conditions and environmental tests the relationship between climate and no conversion guide Stationary use protective properties; --- GB/T 20159.5 between environmental conditions classification Classification of environmental conditions and environmental tests Relations and ground vehicles Transition Guide Transport vehicles; --- GB/T 20159.6 relationship between environmental conditions classification Classification of environmental conditions and environmental tests and Conversion Guide Marine; --- GB/T 20159.7 relationship between environmental conditions classification Classification of environmental conditions and environmental testing and conversion guide and carry Non-stationary use; --- GB/T 20159.8 Classification of environmental conditions and environmental conditions to convert the relationship between the classification and Environmental Testing Guide Introduction; This is Part 7 GB/T 20159 of. The partial modification using IEC TR60721-4-7.2003 "Classification of environmental conditions. Part 4-7. IEC 60721-3 Environmental conditions in points Classes and IEC 60068 in the relationship between the environmental testing and conversion guide to carry and use non-fixed "(in English). Taking into account the actual situation in China, this part of the IEC 60721-4-7 made the following modifications. --- "IEC 60721 Part of the present" was changed to "GB/T 20159 in this section." --- The "Technical Report" to "in this section." --- Remove the IEC 60721-4-7 foreword. --- Increase the national standard foreword. --- Cited international standards of our standards, rather than international standards, and change the order in which to fit the national conditions of China. --- For the original IEC referenced in IEC 60068-2-56. 1988 (corresponding to test Cb), due to the merger has now revised IEC 60068-2-78.2001 (corresponding to test Cab), this section uses when referring to reference the appropriate GB/T 2423.3- 2006, corresponding to the test for the Cab. --- According to GB/T 4798.7 parameters Appendix A Form A. c 1) is the relative humidity level in line arguments made repair 7K5 Changed from "4%" is replaced by "5%", and the corresponding increase in footnotes. --- Within each table after the table name in parentheses narrative level, according to GB/T 4798.7 the content of IEC 's narrative be repaired Changes and additions. --- For the mechanical conditions of Table 5, Table 6, Table 7 acceleration spectral density (ASD) unit, IEC original use m2/s3, in this section According to China's relevant mechanical conditions test GB instead (m/s2) 2/Hz, and add the corresponding footnote in Table 6. Appendix A of this section is an informative annex.
