2000/14/EC - Noise emission in the environment by equipment for use outdoors

This document provides guidance on auditing management systems, including the principles of auditing,
managing an audit programme and conducting management system audits, as well as guidance on
the evaluation of competence of individuals involved in the audit process. These activities include the
individual(s) managing the audit programme, auditors and audit teams.
It is applicable to all organizations that need to plan and conduct internal or external audits of
management systems or manage an audit programme.
The application of this document to other types of audits is possible, provided that special consideration
is given to the specific competence needed.

This European Standard specifies all the information necessary to carry out efficiently and under standardized conditions the determination, declaration and verification of the airborne noise emission of liquid pumps or pump units (see 4.1). It specifies the noise measurement methods and the operating and mounting conditions that shall be used for the test.
Noise emission characteristics include emission sound pressure levels at specified positions and the sound power level. The determination of these quantities is necessary for:
- Declaring the noise emission values,
- Purpose of noise control at source at the design stage.
NOTE The determination of these quantities is also necessary for comparing the noise emitted by liquid pumps on the market.
The use of this European Standard ensures the reproducibility of the determination of the airborne noise emission characteristics within specified limits determined by the grade of accuracy of the basic airborne noise measurement method used. Noise measurement methods according to this European Standard are engineering methods (grade 2) and survey methods (grade 3).
This European Standard does not deal with the characterization of the structure-borne sound and liquid-borne noise generated by liquid pumps
This European Standard is intended to complement EN 809.

ISO 20361:2007 specifies all the information necessary to carry out efficiently and under standardized conditions the determination, declaration and verification of the airborne noise emission of liquid pumps or pump units. It specifies the noise measurement methods and the operating and mounting conditions that shall be used for the test.
The use of ISO 20361:2007 ensures the reproducibility of the determination of the airborne noise-emission characteristics within specified limits determined by the grade of accuracy of the basic airborne noise measurement method used. Noise measurement methods according to ISO 20361:2006 are engineering methods (grade 2) and survey methods (grade 3).
ISO 20361:2007 does not deal with the characterization of the structure-borne sound and liquid-borne noise generated by liquid pumps.
