standard by BSI Group, 04/30/1976
More info
Full Description
Method for determining the dynamic shear modulus and mechanical damping over a wide temperature range using free torsion oscillations of low frequency. Angles of deformation are such that the shear strain is below 0.5 per cent.Cross References: BS 903:Part A24*BS 907*
