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

BS IEC 61334-3-1 specifies disturbance limits in the frequency range from 3 kHz up to 30 MHz

These diverse practices have

the average values (

and definitions relevant to either IEC or IEEE contexts and their use is described in Clause 4

which can be used to test and make a better product that conforms to the appropriate safety and quality norms

The methods of measurements and the necessary tolerances to secure the interchangeability of recordings are included

along with guidance on their relevance and familiarity to UK users and covers the following areas:

BS 5194-4 assists you regarding the material

It also gives the maximum diameter of the chuck nose

BS EN 1143-1 is the first part in the multi-series that specifies test methods

end-users and providers do not know each other and the structures common to traditional business transactions – such as guarantees and compensation mechanisms – are often absent
