Tappi T494 paper and paperboard Tensile Test Machine

Tensile properties of paper and paperboard
(using constant rate of elongation apparatus)
(Revision of T 494 om-01)
(Underlines indicated changes/corrections since last draft)

Scope

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.
