Note 2 to entry: The relationship between stress and strain is not linear in the case of carbonaceous and graphite materials. The static modulus of elasticity, which is determined from the slope of the straight line from the origin to a stress/strain data point to be defined (secant modulus) is always smaller than the dynamic modulus of elasticity which is derived from the tangent in the origin of the stress-strain curve (tangent modulus).
Sampling and sample preparation shall be in accordance with ISO 8007-1 or ISO 8007-2 or ISO 8007-3 unless otherwise agreed.
If another sampling and method of sample preparation are agreed, then the specific procedures used shall be described in the test report.
Rod-shaped specimens of uniform cross section, preferably of circular or rectangular cross section,shall be used. The end faces shall be perpendicular to the longitudinal axis. The length shall be at least three times the largest cross-sectional dimension of the specimen. In no direction shall the specimen be smaller than two times the diameter of the largest particle size.BS ISO 18142 pdf free download.
