Cancels and replaces the first edition (1985). Specifies a method of measuring the tensile strength, stretch at break and tensile energy absorption of paper and board using a test instrument operating at a constant rate of elongation. Also specifies methods for calculating the tensile index, the tensile energy absorption index and the modulus of elasticity. Applies to all papers and boards, including papers with a high stretch at break if the results are within the capacity of the test instrument. Also applies to the components of corrugated board but not, however, to corrugated board itself.
