Abstract

Describes a method for determining the noise emitted by earth-moving machinery and agricultural tractors at the operator's position in terms of the equivalent continuous A-weighted sound pressure level while the machine is stationary.

Scope

This Standard describes a method for determining the noise emitted by earth-moving machinery and agricultural tractors at the operator's position in terms of the equivalent continuous A-weighted sound pressure level while the machine is stationary.

This Standard applies to the following types of machinery:
(a) Agricultural tractors.
(b) Crawlers and wheeled excavators.
(c) Crawlers and wheeled loaders.
(d) Crawlers and wheeled dozers.
(e) Backhoe loaders.
(f) Graders.
(g) Compactor/rollers.
(h) Four-wheel drive skid-steer machines.
