Reciprocating internal combustion engines — Test code for the measurement of structure-borne noise emitted from high-speed and medium-speed reciprocating internal combustion engines measured at the engine feet Published (Edition 2, 2026)

Abstract

This document specifies the procedure for measuring the capacity of a high-speed or medium-speed engine to generate vibration and the determination of the frequency limits of validity of the information quoted. The method described in this document is not suitable for low-speed engines. This document describes an engineering and not a precision method. Whether the tests are carried out on the test bed or on site will be agreed between the user and the manufacturer.

This document is applicable to high-speed and medium-speed reciprocating internal combustion engines for land, rail traction and marine use; this document is not applicable to engines used to propel agricultural tractors, road vehicles and aircraft. This document can also be applied to engines used to propel road-construction and earth-moving machines, industrial trucks and for other applications with engines where no suitable International Standard exists.
