Sound system equipment - Electroacoustical transducers - Measurement of suspension parts

IEC 62459:2010 applies to the suspension parts of electroacoustic transducers (for example, loudspeakers). It defines the parameters and measurement method to determine the properties of suspension parts like spiders, surrounds, diaphragms or cones before being assembled in the transducer. The measurement results are needed for engineering design purposes and for quality control. Furthermore, this method is intended to improve the correlation of measurements between suspension-part manufacturers and loudspeaker manufacturers. The measurement methods provide parameters based on linear and nonlinear modelling of the suspension part and uses both static and dynamic techniques. It cancels and replaces IEC/PAS 62459 published in 2006. It constitutes a technical revision. The main changes are:
- descriptions of the methods of measurement are adjusted to the state of the technology;
- addition of Clauses 5 to 13;
- integration of Annex A in the main body of the standard;
- overall textual review.
The contents of the corrigendum of November 2015 have been included in this copy.

Equipements pour systèmes électroacoustiques – Transducteurs électroacoustiques – Mesurage des pièces de suspension

L'IEC 62459:2010 s'applique aux pièces de suspension des transducteurs électroacoustiques (haut-parleurs, par exemple). Elle définit les paramètres et la méthode de mesurage pour déterminer les propriétés des pièces de suspension comme les spiders, les suspensions périphériques, les diaphragmes ou les cônes, avant leur assemblage dans le transducteur. Les résultats de mesurage sont nécessaires pour la conception technique et le contrôle qualité. En outre, cette méthode a pour objet d'améliorer la corrélation des mesures entre les fabricants de pièces de suspension et de haut-parleurs.
Les méthodes de mesurage fournissent des paramètres déterminés par une modélisation linéaire et non linéaire de la pièce de suspension; elles reposent sur des techniques statiques et dynamiques.
L'IEC 62459:2010 annule et remplace l'IEC/PAS 62459 parue en 2006. Elle constitue une révision technique. Les principales modifications sont les suivantes:
– la description des méthodes de mesurage a été adaptée à l'état de la technologie;
– les Articles 5 à 13 ont été ajoutés;
– l'Annexe A "Code de pratique" a été intégrée à la partie principale de la norme;
– le texte a été revu dans son intégralité.
The contents of the corrigendum of November 2015 have been included in this copy.
