Full Description



This method describes a procedure, using constant rate-of-elongation equipment, for determining three tensile breaking properties of paper and paperboard, namely: (1) tensile strength, (2) stretch, and (3) tensile energy absorption (Tensile strength is indicative of the serviceability of papers, such as wrapping, bag, gummed tape, cable wrapping and printing papers, which are subjected to direct tensile stress. Stretch is indicative of the ability of paper to conform to a desired contour and is important for towels, napkins, decorative papers, cup stock, industrially-used paper tapes and bags used for lining cans, barrels or cartons. Tensile energy absorption is indicative of the durability of papers which will be subjected in use to repetitive straining or impact through rough handling, such as multiwall sacks, carrier boards, and other packaging materials.). The method is applicable to all types of paper and board within the limitations of the instruments used. It does not apply to high stretch creped papers or combined corrugated board.

The testing and evaluation of a product against this method may require the use of materials and/or equipment that could be hazardous. This document does not purport to address all the safety aspects associated with its use. Anyone using this method has the responsibility to consult the appropriate authorities and to establish appropriate health and safety practices in conjunction with any existing applicable regulatory requirements prior to its use.
