Foreword

This standard is designed for use in conjunction with other documents such as the IEEE 1101 group of standards, the IEEE 896 group of standards, the IEEE 1596 group of standards, the IEEE 1014 group of standards, and ISO/IEC 10861: 1994. This standard is one of the IEEE P1156.x series for environmental specifications. It is intended to be used as a core specification. It contains minimum environmental withstand conditions applicable to computer systems and all of their associated components. It has been created to provide general environmental withstand conditions for one or more of the above listed computer busses or interconnect standards, and electronic equipment in general.

With the introduction of numerous standards for computer hardware, components, circuit packs, backplanes, systems, etc., the Microprocessor and Microcomputer Standards Subcommittee of the IEEE Computer Society found it appropriate to write a separate standard for core environmental withstand conditions for computers.

This standard provides design engineers and system engineers with requirements for core environmental conditions that computer systems should be able to withstand, depending upon their environment. These include (but are not limited to) thermal, atmospheric, shock, vibration, flammability, and corrosion stresses during storage and operation.

Scope

This standard is designed for use in conjunction with other standards such as the IEEE 1101 group of standards (Mechanical Specification for Microconnectors and Eurocard Form Factors), the IEEE 896 group of standards (Futurebus+®), the IEEE 1596 group of standards (Scalable Coherent Interface), the IEEE 1014 group of standards (VMEBus), and ISO/IEC 10861:1994 (MULTIBUS II).

This standard is one of the IEEE P1156.x series for environmental specifications. It is intended to be used as a core specification. It contains minimum environmental withstand conditions applicable to computer systems and all of their associated components. It has been created to provide general environmental withstand conditions for one or more of the above listed computer busses or interconnect standards, and electronic equipment in general.

While this standard was specifically created for use with IEEE Computer Society bus standards, nothing herein is intended to restrict its use for other applications, where applicable. A supplier and user may agree to more or less restrictive environmental specifications than those listed below. However, if their specifications are less restrictive than those listed herein, neither supplier nor user may claim conformance to this standard.
