TMI Gurley Gurley is the standard instrument for measuring porosity, air permeability, or the air resistance of d7774 products. Auburn University Auburn, Alabama webmaster eng.

Wherever you are located, it is a practical, cost-effective way to make sure your instruments maintain proper working performance. 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 xstm.

Constant rate of loading method. This test method provides a quick reliable means to measure the zero-span tensile strength of a randomly oriented specimen of fibers when dry. ASTM D This test method covers measurements of the bursting strength of paper and paper products occurring as single or laminated flat sheets not over 0.

The TSO Tester is an ultrasonic instrument for measuring Tensile Stiffness Index or Tensile Stiffness Orientation properties on sheets in machine and cross directions sheet paper samples.

These models can also be fitted with a device to measure the deflection of the sample prior to burst. Taber Bending Stiffness This instrument measures the bending moment required to deflect the free end of a 1.

Determination of tensile strength, stretch at break and tensile energy absorption. Burst Tester for Corrugated and Board Burst Testers are used as a multi-directional tensile test to identify failure in the direction of least resistance for evaluating bursting strength and fiber bond.

Determination of tensile properties. It is also useful for indicating the deterioration of material upon aging. Output asmt are paper strength in force units standard or metricelongation at break as a percent from the original gauge length. The Brightimeter Micro S5 measures brightness, opacity, color, and fluorescence. The clamp pressure is adjustable making it possible to asstm different printing settings.

The maximum force causing failure is measured and given aatm pound. Models are available to test paper, foils, and tissue.

Output results are paper strength in force units standard or metricelongation at break as a percent from the original gauge Output results are paper strength in force units standard or metricelongation at break as a percent from the astk gauge length.

Models are available to test a variety of materials. ASTM D These test methods measure the wet tensile breaking strength of paper, paper products, and paperboard excluding corrugated board when saturated with water. 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. On this machine, we can change sample width, gauge length, and loading rate.

Method for determination of the tensile strength of paper and board after immersion in water. ASTM D certified calibration services and product sales for paper burst testers. Determination of bending strength by the three-point method.

International Standards — Paper and Cardboard. With its high speed and pressure setting the Parker Print Surf simulates the way ink is applied during the printing process.

ASTM D 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. This test method covers measurements of the bursting strength of paper and paper products occurring as single or laminated flat sheets not over 0. Determination of flexural modulus by the three-point method.

Speck size, count and distribution are obtained. 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. Chinese English German Spanish. It measures the ability of a sheet of material paper ast, withstand repeated folding. ASTM D This test method provides a quick reliable means to measure the zero-span d77 strength of a randomly oriented specimen of fibers when dry.
