21.240 - Rotary-reciprocating mechanisms and their parts

IEC 60297-3-100:2008 specifies the basic dimensions of front panels, subracks, chassis, racks and cabinets of the 482,6 mm (19 in) series. Subsequent standards of the associated IEC 60297-3 series provide detail dimensions for specific parts of the equipment practice, where the basic dimensions are used as interface to other associated parts.

Specifies the general conditions and procedures for the measurement and evaluation of vibration, using measurements made on the non-rotating parts of machines with power ratings above 100 kW. Typical examples of application are marine propulsion engines, engines in diesel generator sets, gas compressors and engines for diesel locomotives. Does not apply to machines installed in road vehicles.
