NF EN ISO 20361
Liquid pumps and pump units - Noise test code - Grades 2 and 3 of accuracy
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.

Le présent document spécifie les méthodes de détermination du niveau de bruit émis par les groupes motopompes ou les pompes prises seules de ces mêmes groupes. En fonction des conditions de réalisation de l'essai (banc spécifique, banc d'essai classique, mesure sur site), et de la puissance de la pompe ou du groupe moto-pompe, il précise les normes de base qui sont préférentiellement à utiliser ainsi que les conditions particulières d'essais.

The Requirements department helps you quickly locate within the normative text:
- mandatory clauses to satisfy,
- non-essential but useful clauses to know, such as permissions and recommendations.
The identification of these types of clauses is based on the document “ISO / IEC Directives, Part 2 - Principles and rules of structure and drafting of ISO documents ”as well as on a constantly enriched list of verbal forms.
