Introduction

GB/T 4798 "Environmental Condition Classification Environmental Parameter Group Classification and Severity Classification" covers the product in storage, transportation and handling, Environmental conditions that may be encountered during installation and use: For different conditions of use (such as fixed use with weather protection, installation on the ground vehicle On-vehicle, transport and handling) products are given separate parameter classes: These classifications also take into account the extent to which the product is limited in use: degrees, from severely restricted conditions (such as in a temperature-controlled room) to unlimited conditions: GB/T 4798 is proposed to be composed of the following 10 parts: --- Part 1: Storage: The purpose is to give the classification of the environmental parameters and their severity during the storage process of the product: --- Part 2: Transport and handling: The purpose is to give the environmental parameter group and its severe cool rating: --- Part 3: Stationary use in weather-protected places: The purpose is to give the products that are subjected to fixed use in weather-protected places Environmental parameter groups and their severity ratings: --- Part 4: Stationary use without weather protection: The purpose is to give the product to withstand the fixed use in the place without weather protection Environmental parameter groups and their severity ratings: --- Part 5: Use of ground vehicles: The purpose is to give the environmental parameters to which products installed in vehicles but not constituting vehicles are subjected Groups and their severity ratings: --- Part 6: Marine: The purpose is to give the environmental parameter group and its severity classification that the products installed on the ship are subjected to: --- Part 7: Portable and non-stationary use: The purpose is to give the environmental parameter groups that the products for portable and non-fixed use are subjected to and its severity rating: --- Part 9: Microclimate inside the product: The purpose is to give the environmental parameter group and its severe degree that the internal components of the product are subjected to degree grading: --- Part 10: Introduction: The purpose is to give guidelines for the use of GB/T 4798: --- Part 11: Environmental severity distribution map drawing: The purpose is to draw the distribution map of the severity of the service environment of the product method: This revision to GB/T 4798:3 is equivalent to adopting IEC 60721-3-3:2019 "Classification of Environmental Conditions Part 3-3: Environmental Parameters Group classification and its severity classification are fixed for use in climate protection places: After revision, it is consistent with the level of international standards, which is conducive to Eliminate technical barriers to trade and better promote trade, exchanges and technical cooperation: Classification of environmental conditions Classification of Environmental Parameter Groups and Severity Grading Part 3: Fixed use in weather protected places
