scope:
This test method defines the equipment and techniques for measuring stiffness, as indicated by the deflection distance when the spider is loaded at its center by a specified mass. Stiffness can then be calculated in newtons per millimeter (N/mm), or merely stated in deflection versus mass, as is customary in the loudspeaker industry.
This Standard is issued to improve correlation of measurements in the industry by a standard test method. There is no other industry standard test method.
