BS EN 62459:2011

This standard BS EN 62459:2011 Sound system equipment. Electroacoustic transducers. Measurement of suspension parts is classified in these ICS categories:

• 33.180.99 Other fibre optic equipment
• 31.260 Optoelectronics. Laser equipment
• 33.160.50 Accessories

This International Standard 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.
