This document applies to products that are stored, transported, handled, and used in dry and hot environments. Applicable items and levels can be selected according to the environmental shock and degree of the product.2 Normative referencesThe following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. GB/T 4798.10, Environmental conditions existing in the application of electric and electronic products - Guidance GB/T 20625, Special environmental condition - Terminology3 Terms and definitionsFor the purposes of this document, the terms and definitions defined in GB/T 20625 apply.4 Overview of environmental conditionsThe dry heat environmental conditions are described by climatic environmental conditions (K), special climatic environmental conditions (Z), biological environmental conditions (B), chemically active substances (C), mechanically active substances (S) and mechanical environmental conditions (M) respectively. Environmental condition classification allows for possible combinations of various environmental conditions. It can truly reflect the shock of environmental conditions on product storage, transportation, loading-unloading, and use. For some environmental parameters, it is difficult to quantify its severity level. According to GB/T 4798.10, the environmental condition level is characterized by the following identifications: - The first digit identifies the application condition (1 means storage; 2 means transportation and loading-unloading; 3 means fixed use in places with climate protection; 4 means fixed use in places without climate protection); - Letters: Climatic environmental conditions (K), special climatic environmental conditions (Z), biological environmental conditions (B), chemically active substances (C), mechanically active substances (S) and mechanical environmental conditions (M); - Another digit identifies the severity. Generally, the larger the value, the more severe the condition. A level can be further divided into H (high) and L (low). For example, temperatures may be very low, but high ambient conditions will not occur. Example: Level 2K3, in which: 2 means transportation and loading-unloading; K means climatic environmental conditions; 3 means severity level.5 Severity level for various environmental conditions5.1 Climatic environmental conditions (K) Choose the right level. It is necessary to pay attention to whether the climatic environmental conditions of the place with climate protection are affected by the environment of the place without climate protection, especially the temperature and solar radiation. The severity levels of climatic environmental conditions are shown in Table 1. 1K10: Suitable for indoor storage under dry and hot environmental conditions, without temperature and humidity control. 1K11: Suitable for outdoor sheltered storage under dry and hot environmental conditions. 1K12: Suitable for storage without shelter outdoors under dry and hot environmental conditions. 2K10: Suitable for climate-protected transport and loading-unloading in dry and hot ambient conditions, without temperature and humidity control in unventilated enclosures. 2K11: Suitable for transport and loading-unloading without weather protection in hot and dry ambient conditions. where industrial production activities are distributed throughout the area, or in cities with heavy traffic. 2C3: Suitable for transportation and loading-unloading in areas close to industrial chemical pollution sources. 3C1: Suitable for indoor stationary use in rural and urban areas with low industrial activity and moderate traffic. Heating in dense urban areas in winter can lead to increased pollution. 3C2: Suitable for indoor stationary use with general pollution levels, with industrial activities distributed throughout the region or in cities with heavy traffic. 3C3: Suitable for indoor stationary use near industrial sources of chemical emissions. 3C4: Suitable for indoor fixed use in industrial production plants, where high concentrations of chemical pollutants may occur. 4C1: Suitable for outdoor fixed use in rural and urban areas with a small amount of industrial pollution and low traffic. 4C2: Suitable for outdoor fixed use in cities with industrial pollution and heavy traffic. 4C3: Suitable for outdoor fixed use close to chemical pollution sources. 4C4: Suitable for outdoor fixed use in industrial processing plants. Chemical pollutant emissions are in high concentrations. 2S2: Suitable for transport and loading-unloading where limited (anti-sand) measures have been taken to minimize the presence of sand and dust, such as enclosed transport and loading-unloading. 2S3: Suitable for unenclosed transport and loading-unloading near sources of sand and dust, where no special precautions are taken to reduce the presence of sand and dust. 2S4: Suitable for transportation and loading-unloading in sand and dust areas. 3S1: Suitable for closed indoor fixed use where dust-proof measures have been taken to reduce the dust content to a minimum. 3S2: Suitable for closed indoor fixed use without special protective measures to minimize the content of dust and sand, but the place is not located near the source of dust or sand. 3S3: Suitable for closed indoor fixed use close to sand and dust sources, including places where sand or dust content is minimized in urban areas. 4S1: Suitable for outdoor fixed use where dust-proof measures have been taken to minimize the dust content. 4S2: Suitable for outdoor fixed use without special protective measures to minimize the content of dust and sand, but the place is not located near the source of dust or sand. 4S3: Suitable for places close to the source of sand and dust, including fixed outdoor use in urban areas without special protective measures to minimize the content of dust and sand. It is also suitable for outdoor stationary use not affected by natural dust storms or important industrial activities. 4S4: Suitable for outdoor fixed use with windy sand and dust in the air caused by natural conditions or industrial activities. ......Source: Above contents are excerpted from the full-copy PDF -- translated/reviewed by: www.ChineseStandard.net / Wayne Zheng et al.
