International Standards and Conformity Assessment for all electrical, electronic and related technologies



Reference EN 62459:2011
Title Sound system equipment - Electroacoustic transducers - Measurement of suspension parts
Project Number 22166
Abstract/Scope 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.

Normative reference (6) HD 483.1 S2:1989

(1) Date of ratification (dor) date when the Technical Board notes the approval of an EN (and HD for CENELEC), from which time the standard may be said to be approved

(2) Date of availability (dav) date when the definitive text in the official language versions of an approved CEN/CENELEC publication is distributed by the Central Secretariat

(3) Date of announcement (doa) latest date by which the existence of an EN (and HD for CENELEC), a TS or a CWA has to be announced at national level

(4) Date of publication (dop) latest date by which an EN has to be implemented at national level by publication of an identical national standard or by endorsement

(5) Date of withdrawal (dow) latest date by which national standards conflicting with an EN (and HD for CENELEC) have to be withdrawn

(6) This list of normative references is purely indicative. The only official list of normative reference is the list of the published standard.
