- Tensile strength is the maximum tensile force developed in a test specimen before rupture on a tensile tester carried to rupture under prescribed conditions. Tensile Tester "PARAM XLW(EC)" from LABTHINK is a vertical single-column tensile tester designed for testing of paper and low elongation films and foil. On this machine, we can change sample width, gauge length, and loading rate. Output results are paper strength in force units (standard or metric), elongation at break as a percent from the original gauge. Output results are paper strength in force units (standard or metric), elongation at break as a percent from the original gauge length. Tensile strength given is the force per the width of the test specimen, which is 1 inch, usually.

- ASTM D828 - Tensile Properties of Paper and Paperboard Using Constant-Rate-of-Elongation Apparatus

- Bursting strength is the maximum pressure required to rupture the tested material. The sample is held at the perimeter while the hydrostatic pressure is increased at a controlled constant rate under a rubber diaphragm until sample rupture. The L&W Burst-o-matic is designed to measure the bursting strength of sheet materials. Output results are paper burst strength in pressure units (standard or metric), commonly psi.

- The energy consumed to tear the test sample (usually 4 plies of the sheet material) a certain distance is used to calculate the average tearing force. The L&W Tearing Tester measures the tearing strength of paper, fabric, plastic foil, ect. The tearing energy is measured through positional change of machine’s pendulum. Output results is the paper tearing strength in force units standard or metric (usually pounds).

- A strip of sheet (paper) under a standard tension is subjected to double folding oscillations until break. The logarithm to the base 10 of the number of double folds is considered as “Folding Endurance”. It measures the ability of a sheet of material (paper) to withstand repeated folding. It is also useful for indicating the deterioration of material upon aging.

- TAPPI T511 - Folding endurance of paper (MIT tester)

- A strip of sheet (paper) is clamped in two pair of clamps 0.7 mm apart. moving towards each other, sample is compressed in the edge direction. The maximum force causing failure is measured and given in pound. The L&W Compression Strength Tester uses the STFI method of testing for edgewise compression strength of containerboard in the range of 100 – 400 g/m

- The Hagerty Paper Smoothness Tester tests the surface smoothness of paper especially coated. This method is a measurement of the air flow between the specimen (backed by flat glass on the bottom side) and two pressurized, concentric annular lands that are impressed into the sample from the top side. The rate of air flow is related to the surface roughness of paper or paperboard. We use a Haggerty test device to measure Sheffield smoothness.
