This part of ISO 1924 specifies a method of measur-ing the tensile strength of paper and board using an instrument operating at a constant rate of application of tensile force (constant rate of loading) which causes failure of the test piece in a mean time of 20 s ± 5 s. It also specifies methods for calculating the breaking length and tensile index.
It applies, within the limitations of the instruments used, to all papers and boards with the exception of corrugated board, but may be applied to the compo-nents of such board.
This part of ISO 1924 is of general application and is not limited to any particular type of tensile testing apparatus.
