Sound system equipment - Electroacoustic transducers - Measurement of suspension parts
IEC 62459:2010(E) 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.

Equipements pour systèmes électroacoustiques - Transducteurs électroacoustiques - Mesure 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.
Oprema zvokovnega sistema - Elektroakustični pretvorniki - Meritve obesnih delov (IEC 62459:2010)
Ta mednarodni standard velja za obesne dele elektroakustičnih pretvornikov (na primer zvočniki). Določa parametre in metode merjenja za določevanje lastnosti obesnih delov, kot so pajki, ogrodja, diafragme ali stožci, vgrajeni v pretvornike. Rezultati merjenja so potrebni za tehnično projektiranje in za nadzor kakovosti. Poleg tega je ta metoda namenjena izboljšavi korelacije meritev med proizvajalci obesnih delov in proizvajalci zvočnikov. Merilne metode zagotavljajo parametre, zasnovane na linearnem in nelinearnem modeliranju obesnih delov ter uporabljajo statične in dinamične tehnike.

FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence
between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC itself does not provide any attestatio
