Output results are paper strength in force units standard or metricelongation at break as a percent from the original gauge length. The Burst Tester is designed to meet international standards for tests on paper, foils, paper boards, corrugated board, textiles etc.

The clamp pressure is adjustable making it possible to simulate different printing settings.

This method is a measurement ashm the air flow between the specimen backed by flat glass on the bottom side and d7774 pressurized, concentric annular lands that are impressed into the sample from the top side.

This test method provides a quick reliable means to measure the zero-span tensile strength of a randomly oriented specimen of fibers when dry.

Determination of bending strength by the three-point method. The instrument is used for fine paper, coated paper, newsprint, coated board, linerboard, films and foils, packaging and carton board. Tearing Tester 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.

Testing Capabilities by D747 Test Methods. Models are available to test a variety of materials.

Tensile strength, strain at break, tensile energy absorption and tensile stiffness. The maximum force causing failure asstm measured and given in pound. TMI Gurley Gurley is the standard instrument for measuring porosity, air permeability, or the air resistance of paper products. ASTM D This test method provides a quick, reliable means to measure the wet zero-span tensile strength of a specimen of sheeted material.

It measures the ability of a sheet of material paper to withstand repeated folding. Gurley is the standard instrument for measuring porosity, air permeability, or the air resistance of paper products. In our wet processing and testing laboratory, we have a whole line of machines from wood chip digesters, pulpers, repulpers, mixers, to handsheet paper making.

Models are available to test paper, foils, and tissue. The Hagerty Paper Smoothness Tester tests the surface smoothness of paper especially coated. Method for determination of the tensile strength of paper and board after immersion in water. The resistance to bending is calculated from the bending moment and given in Taber units. These test methods measure the wet tensile breaking strength of paper, paper products, and paperboard excluding corrugated board when saturated with water.

The Electronic Micro Gauge measures specimen thickness within the 0 — 3 mm range. Hagerty Paper Smoothness Tester: This test method provides a quick, reliable means to measure the wet zero-span tensile strength of a specimen of sheeted material. Taber Bending Stiffness This instrument measures the bending moment required to deflect the free end of a 1.

The rate of air flow is related to the surface roughness of paper or paperboard.
