Foreword

This standard replaces GB/T 14091-1993 "machinery products Classification of environmental parameters and their severities." This standard compared with GB/T 14091-1993, mainly to do with the following modifications. --- According to GB/T 1.1-2000 "Standardization Guide Part 1. Structure and rules are written standard" requirements of the grid layout The formula has been modified; --- Remove the GB/T 14091-1993 Chapter 2, "reference standard" in this standard last increase "References"; --- Table 11 In addition to peak displacement 1.5mm, peak acceleration 10m/s2 and peak displacement of 2.5mm, peak acceleration 10m/s2 two sets of values, and the peak displacement 3mm, peak acceleration 10m/s2 to peak displacement 3.5mm, peak acceleration Of 10m/s2. This standard by the national electric and electronic products environmental conditions and environmental tests for Standardization Technical Committee (SAC/TC8) and focal points. This standard was drafted. Guangzhou Electric Apparatus Research Institute. The main drafters of this standard. Zhaopei Yu, Liu Kuifang, Yang. This standard replaces the previous standard release case. GB/T 14091-1993. Classification of environmental parameters and mechanical products Their severities

1 Scope

This standard specifies the classification of environmental parameters and mechanical products in the transportation, storage, installation and use in harsh environmental parameters encountered in the process Graded degrees. This standard is applicable to mechanical products, including farm machinery, internal combustion engines, construction machinery, mining machinery, heavy machinery, lifting the transport machinery, petrochemicals General machinery, electrical products, instruments, machine tools, common parts.

2 environmental parameters

2.1 Classification of environmental parameters This standard environmental parameters are divided into five categories. K --- climate parameters B --- biological environmental parameters C --- chemically active substance parameters S --- mechanical parameters of the active substance M --- mechanical environmental parameters 2.2 determine the environmental parameters 2.2.1 product under actual environmental conditions are often complex, and a combination of a plurality of environmental parameters. To determine if a product application when ring When environmental conditions, should consider the following two points. a) lists of environmental parameters affecting the product; b) according to the actual situation, select the appropriate parameters for each severity. 2.2.2 The standard of environmental parameters given, it is to ensure that Common influential parameters are considered at the same time, the product application conditions The choice of environmental parameters, it must also consider the relationship between a combination of environmental parameters.

3 individual environmental parameters severities

Level parameters listed in this standard refers to the degree of the product may be subject to harsh environmental parameters, has been given the parameters of severities, is fully It combines the nature of emerging environmental conditions and application of environmental conditions in the relevant series of standard grade, in order to obtain the environmental conditions in the product description Consistency, standardization purposes. Severities of the criteria listed, including the surrounding medium (air, water, soil, water vapor, ice, oil, etc.) temperature, the product itself does not include hair Temperature of the hot section. Severities primarily associated with the defined environmental conditions, including but not related to the measurement, calibration and other conditions. 3.1 climate parameters 3.1.1 Temperature (℃) -55, -50, -40, -35, -25, -20, -15, -10, -5, + 5, + 15, + 20, + 25, + 30, + 35, + 40, + 45, + 55, + 60, + 70, + 75, + 85, + 100, + 125, + 155, + 200 3.1.2 Temperature change Temperature changes include temperature shock, when the ambient temperature of the product to sudden changes, such as from outside the home, or when the product is exposed to the sun outdoors Light suddenly subjected to rain, water, water jet, the product that is subject to thermal shock. Temperature change rate. 0.1 ℃/min, 0.5 ℃/min, 1 ℃/min, 3 ℃/min, 5 ℃/min, 1 ℃/s, 5 ℃/s ......
