Rigid cellular plastics shear strength tensile testing machine
1.introduction
This tensile testing machine is to determine the shear strength of rigid cellular plastics by applying a shear stress to a test specimen of defined shape by means of metal supports bonded to the specimen and it can also determine shear modulus of rigid cellular plastics.
2. test specimen size
a) length:250mm
b) width:50mm
c) thickness:25mm
3. test method
ISO 1922 rigid cellular plastics—determination of shear strength
GB/T10007 rigid cellular plastics—determination of shear strength
4. test assembly
