For measuring the initial wet web strength and elongation of tissue paper / newsprint strip or pulp. Digital Display with automatic return after rupture. Clamping length 50 & 100 mm, Max. stroke 30 mm. Deformation speed 1.5 ± 0.1 mm/sec. Measuring range 0-19.999 N.
Initial wet web tensile strength: The maximum tensile force per unit width that a wet test piece, made from a pulp under specified condition, will stand before breaking in a tensile test. Initial wet web tensile index: The initial wet web tensile strength divided by the gram mage oven dry basis of the test piece.
Initial wet web stretch: The ratio of the increase in length of a wet test piece, made from a pulp under specified conditions, at the moment when the maximum tensile force is reached during tensile test, to the initial test length. The test length is the free length between the clamps. In practice, the increase in length is measured at the point where the tensile force begins to decrease.
Initial wet web tensile energy absorption index: The initial wet web tensile energy absorption divided by the gram mage (oven dry basis) of the test piece.
