Foreword

GB/T 20159 "between the environmental conditions classification Classification of environmental conditions and environmental tests Relationship and Conversion Guide" is divided into the following section.

--- Storage;

---transport;

--- Use weather protected locations fixed;

--- No fixed workplace climate protection use;

--- Ground vehicles;

--- Marine;

--- Portable and non-stationary use;

---preface.

This is Part 4 GB/T 20159 of.

This section drafted in accordance with GB/T 1.1-2009 given rules.

This section identical with the international standard IEC 60721-4-4:2003 "Classification of environmental conditions - Part 4-4. IEC 60721-3 Environmental Condition Classification and IEC 60068-2 relationship between the environment and conversion guide test without using a fixed workplace climate protection. " this part of the IEC 60721-4-4 made the following editorial changes.

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

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

--- Cited international standards of our standards, rather than international standards, and change the order in which to fit the national conditions of China;

--- Remove the IEC 60721-4-4 foreword and introduction;

--- Increase the national standard foreword;

--- To IEC standard chart made editorial changes.

This part is proposed by the China Electrical Equipment Industrial Association.

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

1 Scope and purpose

This section GB/T 20159 elaboration of the relationship between environmental conditions and environmental tests and conversion guide.

Environmental composed by a number of environmental conditions, such as climate, biological and chemical active substances due to the active substance, and mechanical machinery Other effects produced. This section only consider the mechanical and climatic conditions.

The purpose of this section is to provide a set of guidelines and to facilitate the application form, so the form of interrelated conditions and conversion.
