For the imperial system The mechanical structure of electronic equipment for column and metric series modular series and harmonized dimensional standards requires the establishment of a set of climatic, mechanical environment and safety requirements. The required test specifications and requirements to meet the functional and reliability requirements of electronic equipment. The main problems it solves are. ---Specify the general climate, mechanical environment and safety test specifications and requirements for the mechanical structure of electronic equipment; ---Provide the combination of performance level and protection level of the mechanical structure of electronic equipment; ---Specify the seismic test and requirements for the mechanical structure of electronic equipment; ---Specify the electromagnetic shielding performance test specifications and requirements for cabinets and sub-boxes. GB/T 18663 "Mechanical structure of electronic equipment metric series and inch series test" is for the mechanical structure of electronic equipment (machine A series of environmental test standards formulated by cabinets, racks, sub-boxes, chassis and plug-ins), and it is proposed to be composed of five parts. --- Part 1.Climatic, mechanical testing and safety requirements for cabinets, racks, sub-boxes and chassis. Designed to specify mechanical junctions of electronic equipment Climatic, mechanical environment, and safety requirements common to organizations (cabinets, racks, sub-boxes, and enclosures). --- Part 2.Seismic tests of cabinets and racks. Designed to specify seismic test conditions and criteria for cabinets and racks to evaluate cabinets Or the ability of a rack mechanical structure to withstand a specific seismic intensity. --- Part 3.Electromagnetic shielding performance test of cabinets and sub-boxes. Designed to regulate empty cabinets and sub-boxes at 30MHz~3000MHz Electromagnetic shielding performance tests and class requirements in the frequency range. --- Part 4.Combination of performance levels for modular cabinets. Designed for modular cabinets in IP codes, climate classes, static and dynamic loads Testing, electromagnetic shielding and seismic requirements provide a combination of different protection levels for ease of selection and procurement. --- Part 5.Seismic tests of enclosures, sub-boxes and plug-ins. To specify seismic test conditions and standards for enclosures, sub-boxes and plug-ins, To assess the ability of chassis, sub-box and plug-in mechanical structures to withstand specific seismic intensities. This document specifies the configuration, conditions, sequence, performance requirements and acceptance criteria for seismic testing of electronic equipment enclosures, sub-boxes and plug-in structures Evaluate the mechanical structure strength of electronic equipment chassis, sub-box or plug-in, so that it has certain use and maintenance during and after the earthquake function to help determine an economical seismic solution for the intended use of electronic equipment. Mechanical structure of electronic equipment Metric series and imperial series tests Part 5.Seismic testing of enclosures, subracks and plug-ins1 ScopeThis document specifies the seismic test requirements for enclosures, sub-racks and their plug-ins as defined in the IEC 60297 and IEC 60917 series. according to IEC 60297 and IEC 60917 series, which only apply in whole or in part to the mechanical structure of enclosures, sub-boxes and their plug-ins for electronic equipment, not Suitable for electronic components, equipment or systems within mechanical structures. NOTE. A subrack can be an integral part of a chassis (often referred to in the industry as a subrack or chassis). The purpose of this document is to ensure the physical integrity of enclosures, sub-racks and plug-ins as defined by IEC 60297 and IEC 60917 so that their Maintain certain use and maintenance functions during and after the earthquake. It is designed to provide users with sufficient confidence. Due to the various sizes, weights and mechanical complexities of the IEC 60297 and IEC 60917 series of enclosures, sub-racks and inserts The quality category specifies a minimum seismic test requirement. Therefore, overall quality categories are specified in this document. However, inside the chassis and slot Mass distribution is considered "specific application" and is defined here as "intended use". Uniaxial acceleration or triaxial acceleration for seismic testing is optional.2 Normative referencesThe contents of the following documents constitute essential provisions of this document through normative references in the text.
