Tensile strength: The maximum tensile force developed in a test specimen before rupture on a tensile test carried to rupture under prescribed conditions. Tensile strength is the force per unit width of teste specimen. Tensile index:The tensile strength in N/m divided by gramage Stretch at rupture:The maximum tensile strain developed in the test specimen before rupture in a tensile test carried to rupture under prescribed conditions.The stretch is expressed as a pecentage, i.e., one hundred times the ratio of the increase in length of the test specimen to the original test span.

Roughness of paper or similar material is defined as the volume of air that forced by a specified pressure difference escapes in unit time by passing between the surface of the specimen and flat metal ring resting on a specimen and exerting a definite pressure on it.
A sample is placed on a perfect plane glass plate, measuring head on the test piece a controlled and small air pressure difference read off on selected rotameter tube.
The Bendtsen Smoothness & Porosity Tester is used for determines the smoothness and porosity of paper paperboard and similar material is based on air leak principle.

The freeness of pulp is designed to give a measure of the rate at which a dilute suspension of pulp (3 g of pulp in 1 L of water) may be drained. The freeness, or drainage rate (see TAPPI T 221 “Drainage Time of Pulp”), has been shown to be related to the surface conditions and swelling of the fibers. Besides these factors, the result is dependent also on conditions under which the test is carried out, such as stock preparation, temperature, and water quality.
The procedure was originally designed to yield a test value suitable primarily for the control of manufacture of ground wood. It is also widely used to follow the changes in drainage rate of various chemical pulps during beating and refining. Treatments which produce a large proportion of fines may sometimes cause an anomalous rise of freeness (false freeness) usually at values below 100 mL.
Freeness values do not necessarily correlate with the drainage behavior of pulp material on a commercial paper machine.
The freeness tester consists of a drainage chamber and a rate measuring funnel, mounted on a suitable 1support. The apparatus is manufactured to drawings and specifications and each instrument is inspected and calibrated before delivery. Some instruments may have a coating of marine varnish on the surface
