Acoustics - Noise test code for compressors and vacuum pumps Engineering method (grade 2) (ISO 2151:2004)

This noise test code specifies methods for measurement, determination and declaration of the noise emission from compressors and vacuum pumps: a) measurement of the sound pressure level at the indicated position of the operator; b) derivation of the noise emission expressed as the sound power level of the machine under specified load conditions. This noise test code applies to stationary and portable compressors as specified in EN 1012-1, "Compressors - Safety" and vacuum pumps as specified in EN 1012-2 "Vacuum Pumps - Safety".

Kompressoren und Vakuumpumpen - Bestimmung der Geräuschemission - Verfahren der Genauigkeitsklasse 2 (ISO 2151:2004)

Diese Geräuschprüfvorschrift legt Verfahren zur Messung, Bestimmung und Angabe der Geräuschemission von Kompressoren und Vakuumpumpen fest: a) Messung des Schalldruckpegels am angegebenen Bedienerplatz; b) Ableitung der Geräuschemission ausgedrückt als Schalleistungspegel der Maschine unter festgelegten Belastungsbedingungen. Diese Geräuschprüfvorschrift ist anwendbar auf stationäre und mobile Kompressoren gemäß EN 1012-1 "Kompressoren - Sicherheit" und Vakuumpumpen gemäß EN 1012-2 "Vakuumpumpen - Sicherheit".

Acoustique - Code d'essai acoustique pour les compresseurs et les pompes à vide - Méthode d'expertise (classe de précision 2) (ISO 2151:2004)

Le présent code d'essai acoustique fixe des méthodes de mesurage, de détermination et de déclaration de l'émission sonore provenant des compresseurs et des pompes à vide: a) mesurage du niveau de pression acoustique à la position indiquée de l'opérateur; b) calcul de l'émission sonore exprimée en niveau de puissance acoustique de la machine dans des conditions de charge spécifiées. Le présent code d'essai acoustique s'applique aux compresseurs fixes et mobiles tels que spécifiés dans l'EN 1012-1 "Compresseurs-Sécurité" et aux pompes à vide telles que spécifiées dans l'EN 1012-2 "Pompes à vide-Sécurité".
