The 1680 family of standards defines environmental performance criteria for electronic products. The scope of this document is to provide guidelines and implementation procedures for the standards included in the 1680 family of standards.
Standard for Environmental Assessment of Electronic Products
This standard describes the installation and maintenance procedures for feeder and plug-in busways and accessories rated 600 Volts AC or less, and 100 Amperes or more. It also covers periodic routine maintenance procedures for busway, and special procedures used after adverse operating conditions such as a short-circuit, ground-fault, or immersion in water. This publication does not cover lighting busway, trolley busway, cable-bus, or medium-voltage or metal-enclosed busway.

The purpose of this standard is to create an I/O mezzanine module, which works intimately with an FPGA processing device.
FPGA Mezzanine Card (FMC) Standard
This standard specifies a high-performance backplane bus for use in microcomputer systems that employ single or multiple microprocessors. It is based on the VMEbus specification, released by the VME Manufacturers' Group in August of 1982. The bus includes four subbuses: data transfer bus, priority interrupt bus, arbitration bus, and utility bus. The data transfer bus supports 8-, 16-, and 32-bit transfers over a non-multiplexed 32-bit data and address highway.
Standard for a Versatile Backplane Bus: VMEbus
The basic dimensions of a range of modular subracks conforming to IEC 60297-3 (1984-01) and IEC 60297-4 (1995-03) for mounting in equipment according to IEC 60297-1 (1986-09) and ANSI/EIA 310-D-1992, together with the basic dimensions of a compatible range of plug-in units, printed boards, and backplanes, are covered. The dimensions and tolerances necessary to ensure mechanical function compatibility are provided. This standard offers total system integration guidelines (advantages: shorter design and development time, etc.).
