This test method describes the procedure, using constant-rate-of-elongation equipment, for determining four tensile breaking properties of paper and paperboard: tensile strength, stretch, tensile energy absorption, and tensile stiffness. This procedure is applicable to all types of paper and paperboard within the limitations of the instruments used, whether the instruments perform horizontal or vertical tests or whether they are manually operated or computer controlled. It is also applicable to handsheets, with modifications, as specified in TAPPI T 220 Physical Testing of Pulp Handsheets. It does not apply to combined corrugated board. TAPPI T 404 Tensile Breaking Strength and Elongation of Paper and Paperboard (Using Pendulum-Type Tester) describes a procedure for measuring tensile strength and stretch using constant rate of loading instruments.
