32、ork Equipment Earthquake Resistance. This standard sets forth test setups, performance requirements, and acceptance criteria for determining the robustness of chassis, subracks, and associated plug-in units according to the IEC 60297 and IEC 60917 series that may provide a level of survivability and

33、 preserve functionality during and after a seismic occurrence (an earthquake). This standard does not replace regional seismic system, installation standards, or specifications. The intent of this standard is to provide a common methodology to perform and report seismic test conformance of chassis,

34、subracks, and plug-in units according to the IEC 60297 and IEC 60917 series within a specified weight category. Mass distribution is based on the intended use. The terms “intended use” or “simulation of service condition” or “worst-case simulated configuration” are widely used in the telecom industr

35、y but also in the electronics industry. Seismic ground motion occurs simultaneously and randomly in all directions. Single-axis or tri-axis tests may be selected to simulate the seismic environment for testing. BS EN 61587-5:201461587-5 IEC:2013 7 MECHANICAL STRUCTURES FOR ELECTRONIC EQUIPMENT TESTS

36、 FOR IEC 60917 AND IEC 60297 Part 5: Seismic tests for chassis, subracks and plug-in units 1 Scope and object This part of IEC 61587 specifies seismic test requirements for chassis, subracks, and plug-in units as defined in the IEC 60297 and IEC 60917 series. It applies in whole or in part, only to

37、the mechanical structures of chassis, subracks, and plug-in units for electronic equipment, according to the IEC 60297 and IEC 60917 series, and does not apply to electronic components, equipment or systems within the mechanical structures. NOTE Subracks may be an integral part of a chassis (often c

38、alled in the industry a shelf or a crate). The object of this standard is to establish a level of physical integrity of chassis, subracks, and plug-in units according to IEC 60297 and IEC 60917 series that may provide a level of survivability that will preserve functionality during and after a seism

39、ic occurrence. It is intended to provide the user with a high level of confidence in the selection of an equipment practice to meet such needs. Since IEC 60297 and IEC 60917 series chassis, subracks, and plug-in units come in many sizes, weights and mechanical complexities, it is not possible to def

40、ine a single minimum seismic test requirement for all weight categories. Therefore, overall mass categories are defined in this standard. However, the mass distribution inside a chassis and subrack is considered “application-specific” and herein defined as “intended use”. The single-axis or tri-axis

41、 acceleration for the seismic testing is selectable. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
