and recycling machines when they are used as intended and under the conditions of misuse which are
reasonably foreseeable by the manufacturer associated with the whole life time of the machine (see
Annex C).
The requirements of this part are complementary to the common requirements formulated in
ISO 20500-1.
This document does not repeat the requirements from ISO 20500-1, but adds or replaces the
requirements for application for soil-stabilising machines and recycling machines.
The following significant and relevant hazards are not covered in this document:

Noise test code for soil-stabilising machines and recycling machines
A.1 Scope
This noise test code specifies all the information necessary to carry out efficiently and under standardized
conditions the determination, declaration and verification of the noise emission characteristics of soil-
stabilising machines and recycling machines.
Noise emission characteristics include emission sound pressure levels at workstations and the sound
power level. The determination of those quantities is necessary for:
— manufacturers to declare the noise emitted;
— comparing the noise emitted by machines in the family concerned;
— purposes of noise control at the source at the design stage.
The use of this noise test code ensures reproducibility of the determination of the noise emission
characteristics within specified limits determined by the grade of accuracy of the basic noise
measurement meth
