This document serves as a replacement of GB/T 14092.2-2009 Environmental Condition for Machinery Products - Cold. In comparison with GB/T 14092.2-2009, apart from structural adjustments and editorial modifications, the main technical changes are as follows: a) The content of the chapter “Environmental Condition of Usage” is modified, and the title of the chapter is modified into “Environmental Condition” (see Chapter 4; Chapter 3 of Version 2009); b) The content of the section “parameter values of various environmental conditions” is modified, and the title is modified into “severity levels of various environmental conditions” (see Chapter 5; 3.7 of Version 2009); c) The contents of “environmental condition of climate”, “environmental condition of special climate”, “environmental condition of chemical active substance”, “environmental condition of mechanical active substance” and “mechanical environmental condition” are modified, and the new classification is used to replace the old classification (see Table 1 ~ Table 5; Table 1, Table 2, Table 4 and Table 5 of Version 2009); d) The content of “biological environmental condition” is added (see 5.6). Please be noted that certain content of this document may involve patents. The institution issuing this document does not undertake the responsibility of identifying these patents. Environmental Condition for Machinery Products - Part 2: Cold 1 Scope This document specifies the environmental parameters and severity levels of machinery products in the environmental condition of cold. This document applies to machinery products used in the environmental condition of cold. The environmental condition stipulated in this document include the environmental parameters and severity levels that the products are subject to and affected by. Applicable items and levels are selected for various types of products in accordance with the degree of environmental impact that they are subject to. 2 Normative References The contents of the following documents constitute indispensable clauses of this document through the normative references in the text. In terms of references with a specified date, only versions with a specified date are applicable to this document. In terms of references without a specified date, the latest version (including all the modifications) is applicable to this document. GB/T 4798.10 Environmental Conditions Existing in the Application of Electric and Electronic Products - Guidance 3 Terms and Definitions This document does not have terms or definitions that need to be defined. 4 Environmental Condition The environmental condition of cold is respectively and hierarchically described by the environmental condition of climate (K), the environmental condition of special climate (Z), the condition of chemical active substance (C), the condition of mechanical active substance (S), the condition of mechanical environment (M) and the condition of biological environment (B). The classification of environmental conditions allows possible combinations of multiple environmental conditions, which can truly reflect the impact of environmental conditions on product storage, transportation and usage. For some environmental parameters, it is quite difficult to quantify their severity levels. In accordance with GB/T 4798.10, the level of environmental condition is marked as follows: ---The first digit, which identifies the application conditions (1 indicates storage, 2 indicates transportation, 3 indicates fixed use in a place with weather protection, and 4 indicates fixed use in a non-weather-protected place); ---Letter, the environmental condition of climate (K), the environmental condition of special climate (Z), the condition of chemical active substance (C), the condition of mechanical active substance (S), the mechanical environmental condition (M) and the biological environmental condition (B); ---Another digit, which identifies the severity level. Generally, the larger the value, the more severe the condition. For example: level 2K30, in which, 2 indicates transportation; K indicates the environmental condition of climate; 30 indicates the severity level. 5 Severity Levels of Various Environmental Conditions 5.1 Environmental Condition of Climate (K) When choosing an appropriate level, it is necessary to pay attention to whether the environmental condition of climate in the place with weather protection is affected by the environment without weather protection, especially the impact of temperature and solar radiation. The severity levels of the environmental condition of climate are shown in Table 1. 1K40: applicable to storage with weather protection in the environmental condition of cold, without the control of temperature and relative humidity. 1K41: applicable to outdoor sheltered storage in the environmental condition of cold. 1K42: applicable to outdoor storage without shelter in the environmental condition of cold. 2K40: applicable to transportation with weather protection in the environmental condition of cold, in an unventilated box, without the control of temperature and relative humidity. 2K41: applicable to transportation without weather protection in the environmental condition of cold. 3K40: applicable to fixed use with weather protection in the environmental condition of cold, without the control of temperature and relative humidity. 4K40: applicable to outdoor sheltered fixed use without weather protection in the environmental condition of cold. 4K41: applicable to outdoor fixed use without shelter and weather protection in the environmental condition of cold. 1S4: applicable to open-air storage where windy sand and dusty air are generated by natural conditions or industrial activities. 2S1: applicable to transportation, loading and unloading where dust prevention measures have been taken to reduce the content of sand and dust to a minimum. 2S2: applicable to transportation, loading and unloading where limited (anti-sand and dust) measures have been taken to reduce the presence of sand and dust to a minimum, such as: enclosed transportation, loading and unloading. 2S3: applicable to non-enclosed transportation, loading and unloading near the source of sand and dust, where no special protective measures are taken to reduce the presence of sand and dust to a minimum. 2S4: applicable to transportation, loading and unloading in sandy and dusty areas. 3S1: applicable to closed indoor fixed use where dust prevention measures have been taken to reduce the dust content to a minimum. 3S2: applicable to closed indoor fixed use without special protective measures to reduce the content of dust and sand to a minimum, but the places are not located near the source of dust or sand. 3S3: applicable to closed indoor fixed use close to the source of dust and sand, including places in urban areas where measures are taken to reduce the content of sand or dust to a minimum. 4S1: applicable to outdoor fixed use where dust prevention measures have been taken to reduce the content of dust to a minimum. 4S2: applicable to outdoor fixed use where no special protective measures are taken to reduce the content of sand and dust to a minimum, but the places are not located near the source of dust or sand. 4S3: applicable to places close to the source of sand and dust, including outdoor fixed use in urban areas where there are no special protective measures to reduce the content of dust and sand to a minimum. It is also applicable to outdoor fixed use not affected by natural sandstorms or important industrial activities. 4S4: applicable to outdoor fixed use where windy sand and dusty air are generated by natural conditions or industrial activities. ......
