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 5 GB/T 20159 of.

This section identical with IEC TR60721-4-5:2003 "Classification of environmental conditions. Part 4-5. IEC 60721-3 Environmental conditions in points IEC 60068 and class relations and the conversion between the guide surface of the vehicle environmental testing using the "(in English).

Taking into account the actual situation in China, this part of IEC TR60721-4-5 made the following editorial changes.

--- "IEC 60721 Part of the present" was changed to "GB/T 20159 in this section";

--- The "Technical Report" to "this Part";

--- Remove the IEC 60721-4-5 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;

--- Within each table after the table name in parentheses narrative level, according to GB/T 4798.5 in the content of the IEC text narratives Changes and additions;

--- For the mechanical conditions of Table 3, Table 4 and Table 5 in the 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.

This part of the National Electrical and Electronic Products Environmental conditions and environmental tests for Standardization Technical Committee (SAC/TC8) and focal points.

This section is drafted. Guangzhou Electric Apparatus Research Institute.

1 Scope

GB/T 20159 This part is related to GB/T 4798.5 Environmental conditions and environmental tests GB/T 2423 and transferred between Change guide.

Environment can consist of many environmental conditions and the composition, such as mechanical, climate, and biological active substances due to chemical and mechanical actives Other effects of mass produced. This section only considers mechanical conditions and climatic conditions.

The purpose of this section is to provide a set of guidelines and to facilitate the application form for the specification writer, form these conditions are interrelated and conversion.
