Scope
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 (Note 1).
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. Note 1: 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.
