Foreword
GB/T 14092 "Machinery Products Environmental Conditions" includes the following seven sections.
--- GB/T 14092.1 machinery products humid environmental conditions
--- Cold GB/T 14092.2 machinery products environmental conditions
--- GB/T 14092.3 machinery products environmental conditions of high altitude
--- GB/T 14092.4 environmental conditions of marine machinery products
--- GB/T 14092.5 environmental conditions of industrial machinery products corrosion
--- GB/T 14092.6 mining machinery products environmental conditions
--- GB/T 14092.7 machinery products environmental conditions dry heat
This section GB/T 14092 Part 7.
This Part replaces GB/T 14092.7-1997 "machinery products Environmental conditions dry heat."
This section compared with the GB/T 14092.7-1997, 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;
--- "This standard" be replaced by "this section";
--- Table 2 in the ambient air movement in weather protected place second 3Za4 to 3Za5;
--- Table 7 footnote c of 22.5 ℃ to 22.5 °;
--- Stationary random vibration table, row 7, the "acceleration" a change "acceleration power spectral density";
--- FIG. 1, "the first shock of the maximum response spectrum" to "the impact of the first order maximum response spectrum."
Appendix A of this section is informative appendix.

Machinery products Environmental conditions dry heat
1 Scope
This section provides mechanical products in the dry and hot area environmental parameters and their severities.
This section applies to the dry and hot climate zones for general purposes GB/T 4797.1 predetermined mechanical products, including farm machinery, internal combustion engines, engineering machines
Machinery, mining machinery, heavy machinery, material handling equipment, petrochemical general machinery, electrical products, instruments, machine tools and general parts.

3 Environmental Conditions
Each of environmental conditions by a wide range of environmental parameters. Such as climatic conditions by the environmental parameters temperature, relative humidity and other components. And each ring
Due to the different environmental parameters of the actual situation, it can be divided into a number of severity, such as high temperature into 45 ℃, 50 ℃, 55 ℃ and so on several levels.
Environmental conditions are divided into eight kinds. aeolian geomorphology, groundwater, climatic conditions, the special climatic conditions, biological conditions, chemically active material conditions, machine
Mechanical active material conditions and mechanical conditions.
3.1 Environmental Code
Environmental conditions characteristic represented by the environment code. Environmental Code are generally composed by the site of use, environmental conditions, type, severity of three parts.
Code with numbers and alphabet representation.
The first use of a numerical places. 3 --- weatherprotected stationary use; 4 --- no fixed workplace climate protection use.
The second English letters certain environmental conditions. D --- aeolian geomorphology conditions; W --- groundwater conditions; K --- climatic conditions;
Z --- special climatic conditions (Zh --- thermal radiation; Za --- ambient air movement; Zw --- other water sources other than rain); B --- Bio
Conditions; C --- chemically active material conditions; S --- Mechanical active material conditions; M --- mechanical conditions.
The third digital representation of the severity of environmental conditions, in general the larger the number, the more severe conditions. After the number "L" or "S" table
Some parameter values \u200b\u200bare shown with the original at a different level.
For example, 3K5 indicates weather protected place climatic conditions 5th grade.
3.2 climatic conditions
Climatic condition grade are shown in Table 1.
Note. Dry hot desert climate parameters differ from some type 4K4S 4K4L, other environmental parameters are selected outdoor dry heat type values.
