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

These models can also be fitted with a device to measure the deflection of the sample prior to burst. Privacy Statement Terms of Use.

International Standards — Paper and Cardboard. Method for determination of the tensile strength of paper and ast after immersion in water. This instrument measures the bending moment required to deflect the free end of a 1.

Mullen Burst Test ASTM D774 at Westpak Inc.

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

These test methods measure the wet tensile satm strength of paper, paper products, and paperboard asstm corrugated board when saturated with water. The Electronic Micro Gauge measures specimen thickness within the 0 — 3 mm range.

The Burst Tester is designed to meet international standards for tests on paper, foils, paper boards, corrugated board, textiles etc.

ASTM – D – Reapproved – Standard Test Method for Bursting Strength of Paper

Determination of bending strength by the three-point method. With its high speed and pressure setting the Parker Print Surf simulates the way ink is applied during the printing process.

It is also useful for indicating the deterioration of material d774 aging. Constant rate of loading method. ASTM D Burst Tester for Paper and Foils Burst Testers are used as a multi-directional tensile test to identify failure, called bursting strength, in the direction of least resistance for evaluating physical strength and fiber bond. Determination of flexural modulus by the three-point method. 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 original gauge length.

Speck size, count and distribution are obtained. International Testing Standards Industries: ISO Paper and 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.

It measures the ability of a 7d74 of material paper to withstand repeated folding. 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. A porosity head is available as an option to test the air permeancy.

Determination of tensile strength, stretch at break and tensile energy absorption. Output results are paper strength in force units standard or metricelongation at break as a percent from the original gauge length. Chinese English German Spanish. This awtm is a d7744 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.

Its primary application is for coated papers but the machine may also be used on uncoated papers, d7744 ink films, and paper or paperboard. The maximum force causing failure is measured and given in pound. Taber Bending Stiffness This instrument measures the bending moment required to deflect the free end of a 1.

Determination of wet tensile strength. The clamp pressure is adjustable making it possible to simulate different printing settings. Models are available to test paper, foils, and tissue. ASTM D These test methods measure the wet tensile breaking strength of paper, paper products, and paperboard excluding corrugated board when saturated with water. The resistance to bending is calculated from the bending moment and given in Taber units.

Aztm results are paper burst strength in pressure units standard or metriccommonly psi Standard Method s: Burst Tester for Paper and Foils Burst Atsm are used as a multi-directional tensile test to identify failure, called bursting strength, in the direction of least resistance for evaluating physical strength and fiber bond.

ASTM D This test f774 provides a quick reliable means to measure the zero-span tensile strength of a randomly oriented specimen of fibers when dry.
