ISO 7267-3 is a standard that specifies a method for measuring the dynamic mechanical properties of rubber and rubber-like materials using a torsional oscillation method. This standard is part of a series of ISO standards related to the measurement of dynamic mechanical properties of rubber materials, which are important mechanical properties that can affect the performance of rubber products in a variety of applications.

The test method specified in ISO 7267-3 involves subjecting a sample of the rubber material to a small, sinusoidal twist at a known frequency and measuring the resulting torque and phase angle of the twist. From these measurements, the loss factor and modulus of rigidity can be calculated, which provide information about the material’s ability to dissipate energy and resist deformation under dynamic loading.

ISO 7267-3 is widely used in the rubber industry for quality control and material specification purposes. It is also used in research and development to study the effects of various factors on the dynamic mechanical properties of rubber materials, such as temperature, frequency, and composition.

NextGen’s Pusey & Jones Portable Hardness Tester complies with ISO 7267-3 standard.
