Scope

This standard specifies the measurement methods and rating criteria for the
vibration of the non-rotating and non-reciprocating parts of reciprocating diesel
engines. Shaft vibrations (including torsional vibrations) are outside the scope
of this standard.
This standard is applicable to the reciprocating-piston diesel engines with rigid
or flexible support. The typical applications are diesel engines for low-speed
trucks, three-wheeled vehicles, tractors, irrigation pumps, marine main engines,
marine auxiliary engines, generator sets, etc.
This standard also applies to matched machines that are driven by
reciprocating machines or that drive reciprocating machines. For the purposes
of this, it shall follow the relevant criteria and rating for assessment.
This standard does not apply to reciprocating diesel engines which have a
power greater than 100 kW and is installed on road vehicles (such as industrial
trucks).
The rating criteria as provided by this standard apply to operational monitoring
and acceptance tests, to assess the adverse effects of mechanical vibration of
diesel engines on equipment which is directly installed on diesel engines.
The rating criteria as provided in this standard do not apply to the assessment
of internal parts of diesel engines. For example, problems related to valves,
pistons, piston rings, etc. may not be reflected in the measurement, the
identification of these problems requires the use of research techniques. The
same noise is also not within the scope of this standard.

Summary	This standard specifies the methods of measurement and rating criteria for non-rotating and reciprocating diesel machine vibration of non- reciprocating parts. Shaft vibration (including torsional vibration) is not within the scope of this standard. This standard applies to rigid or flexible support of reciprocating piston engine. Typical uses for low-speed vehicles, three cars, tractor, irrigation pumps, marine host, marine auxiliary diesel engine and generator set. This standard also applies to reciprocating machines driven or driven by a reciprocating machinery supporting machines, which should be to assess the standards and classification. This standard does not apply to installation in road vehicles (such as industrial trucks) on a reciprocating engine power greater than 100kW.
