Introduction

GB/T 4798 "Environmental Condition Classification Environmental Parameter Group Classification and Severity Classification" covers the product in transportation, installation, storage and Environmental conditions that may be encountered during use: For different conditions of use (such as fixed use with weather protection, installation on ground vehicles, Shipping and handling) products are given individual parameter grades: These classifications also take into account the degree of restriction of the product in use, ranging from strict from limited 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 environmental parameters and severity classification of the product during storage: --- 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 4798:4 is equivalent to adopting IEC 60721-3-4:2019 "Classification of Environmental Conditions Part 3-4: Environmental Parameters Group classification and its severity classification "Fixed use in places without climate protection", the revision 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 4: Stationary use in places without weather protection

1 Scope

3 Terms and Definitions

The following terms and definitions apply to this document: The URLs of the main ISO and IEC technical data used in this document are as follows: ISO online browsing platform: http://www:iso:org/obp 3:1 fixed use stationaryuse The use of products that are securely mounted to a structure or permanently placed in a specific location: 3:2 Locations where the product cannot be protected from direct exposure to the weather: 3:3 sheltered location Locations where the product is protected from structures subject to direct weather, such as direct sunlight, rain:

4 General requirements

A product may be exposed to a wide range of environmental conditions during its service life: These environmental conditions are specified in IEC 60721-3 (all parts) It is used to define the extreme value of short-term environmental stress that the product can withstand: However, these classifications do not provide a long-term or comprehensive information on environmental stresses during service life: This means that product stability or service life reliability cannot be determined solely from
