Specifies the general principles to be observed in the preparation of test methods for determining the bending stiffness of all types of paper and board using static methods, by applying line loading to which the mass of the test piece makes negligible contribution. In detail, it describes principle, apparatus, limitations on use of instruments, sampling, conditioning, preparation of test pieces, procedure, expression of results, test report.
