Mechanical vibration and shock. Characterization of the dynamic mechanical properties of visco-elastic materials - Dynamic stiffness method1 Scope This part of ISO 18437 specifies a direct method for measuring the complex dynamic moduli of elasticity (the Young, shear and bulk moduli, and their respective loss factors corresponding to the tensile, shear and all compressive strains) for polymeric (rubbery and viscous polymers, as well as rigid plastics) materials over a wide frequency and temperature range. Measurements are performed by the dynamic stiffness method, which uses electric

The aim of BS 6336 is to provide best industry guidance in the development of standardized test methods that will minimize fire hazards
