Polyethylene (PE) materials for piping systems. Determination of Strain Hardening Modulus in relation to slow crack growth. Test method1 Scope This International Standard specifies a method for the determination of the strain hardening modulus which is used as a measure for the resistance to slow crack growth of polyethylene. The strain hardening modulus is obtained from stress strain curves on compression moulded samples. This International Standard describes how such measurement is performed and how the strain hardening modulus shall be determined from such a curve. Details of the

Recommendation for the maximum length of the intra-oral mirror has been reduced from 178 mm to 173 mm in 1

The purpose of these methods is an optimal materials application for weight reduction or enhanced capability and lifespan of the components
