Foreword

GB/T 14093 "Technical Requirements for Mechanical Products" includes the following seven parts.

---GB/T 14093.1 Environmental requirements for mechanical products, hot and humid environment

---GB/T 14093.2 Mechanical products Environmental technical requirements Cold environment

---GB/T 14093.3 Mechanical product environmental technology requirements plateau environment

---GB/T 14093.4 Mechanical products Environmental technical requirements Industrial corrosion environment

---GB/T 14093.5 Mechanical product environmental technical requirements dry heat environment

---GB/T 14093.6 Mechanical product environmental technical requirements marine environment

---GB/T 14093.7 Mechanical products environmental technology to show the mine environment This part is the fifth part of GB/T 14093. This part replaces GB/T 14093.5-1997 "Environmental technical requirements for mechanical products for dry heat environment". Compared with GB/T 14093.5-1997, the main changes in this part are as follows:

--- According to the requirements of GB/T 1.1-2000 "Standardization Work Guide Part 1. Standard Structure and Writing Rules" Modifications have been made;

--- "This standard" was changed to "this section";

--- Updated the reference standard. Appendix A, Appendix B and Appendix C of this part are informative annexes. This part is proposed and managed by the National Technical Committee for Environmental Conditions and Environmental Testing Standardization of Electrical and Electronic Products (SAC/TC8). This section drafted by: Guangzhou Electric Apparatus Research Institute. The main drafters of this section. Liu Kuifang, Xiao Li. The previous versions of the standards replaced by this part are. GB/T 14093.5-1997. GB/T 14093.5-2009 Mechanical product environmental technical requirements Dry heat environment

1 Scope

GB/T 14093.5-2009 is the Chinese national standard on environmental technology requirements of machinery products for dry heat environments, in the field of testing. The /T suffix marks it as a recommended standard: it is not compulsory by itself, but it becomes binding as soon as a contract, a tender or a customer specification calls it up - which in practice is how most foreign buyers meet it. It was issued on 6 May 2009 by the General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China; Standardization Administration of China, and has been in force since 1 November 2009. Classification: ICS 19.020, CCS A21. This page is published from the official record of the standard held by the Chinese standards administration: the identification, the dates, the classification and the issuing body are taken from there. The clause text, the tables and the numeric limits are in the document itself, which is delivered complete in English translation.

This part specifies the types of protection, environmental conditions, technical requirements, test methods, acceptance rules and standards for mechanical products used in dry heat environments. Requirements for packaging, packaging, transportation and storage. This section applies to general purpose mechanical products used in dry and hot climate zones as specified in GB/T 4797.1-2005. Large product The categories include agricultural machinery, internal combustion engines, construction machinery, lifting and transportation machinery, heavy machinery, petrochemical general machinery, electrical products, instrumentation, machine tools. With general parts and so on.
