    Significance and Use

    5.1 This guide is intended to describe various methods for determining the dynamic properties of vulcanized rubber materials, and by extension, products utilizing such materials in applications such as springs, dampers, and flexible load-carrying devices, flexible power transmission couplings, vibration isolation components and mechanical rubber goods in general. As a guide, it is intended to provide descriptions of options available rather than to specify the use of any one in particular.

    1. Scope

    1.1 This guide covers dynamic testing of vulcanized rubber and rubber-like (both hereinafter termed “rubber” or “elastomeric”) materials and products, leading from the definitions of terms used, through the basic mathematics and symbols, to the measurement of stiffness and damping, and finally through the use of specimen geometry and flexing method, to the measurement of dynamic modulus.

    1.2 This guide describes a variety of vibratory methods for determining dynamic properties, presenting them as options, not as requirements. The methods involve free resonant vibration, and forced resonant and nonresonant vibration. In the latter two cases the input is assumed to be sinusoidal.

    1.3 While the methods are primarily for the measurement of modulus, a material property, they may in many cases be applied to measurements of the properties of full-scale products.

    1.4 The methods described are primarily useful over the range of temperatures from −70°C to +200°C (−100°F to +400°F) and for frequencies from 0.01 to 100 Hz. Not all instruments and methods will accommodate the entire ranges.

    1.5 When employed for the measurement of dynamic modulus, the methods are intended for materials having complex moduli in the range from 100 to 100 000 kPa (15 to 15 000 psi) and damping angles from 0 to 90°. Not all instruments and methods will accommodate the entire ranges.

    1.6 Both translational and rotational methods are described. To simplify generic descriptions, the terminology of translation is used. The subject matter applies equally to the rotational mode, substituting “torque” and “angular deflection” for “force” and “displacement.”
