Recommended methods for the determination of the dielectric properties of insulating materials at frequencies above 300 MHz - GeneralWhat is BS 7737 1 Dielectric properties of insulating materials about? BS 7737 1 is an international standard that applies to the procedures for the determination of relative permittivity and dielectric dissipation factor and of quantities related to them, such as the loss index, of dielectric materials in the microwave frequency region (i. e. frequencies above about 300 MHz up to optical frequencies). Unlike the test methods employed at lower

BS 8213-4:2007 replaces the 1990 edition which is now withdrawn

The stated precision provides values for the magnitude of variability that can be expected between test results when the method described in ISO 6974-1 is applied in one or more competent laboratories

This part of BS 6400 applies to primary meter installations:

It describes methods for measuring the thickness of coatings applied to a substrate including for determining wet-film thickness
