Give one of our application engineers a call today for help with creating the best budget and testing plan according to ASTM D Test a substitute specimen to replace the discarded result.

Last previous edition D — We offer machines, apparatus, testers, tensile grips, test fixtures, clamps, holders, jigs, faces, jaws, extensometers, environmental and humidity chambers, furnaces, baths and custom solutions for unique applications.

This standard has been approved for use by agencies of the Department of Defense. NOTE 1—Cohesive failure may be obtained by observing how much of the failure has occurred in the adhesive itself. Contact failure refers to lack of glue lines being in contact due to uneven surfaces, poor pressure distribution, etc. Precision and Bias Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM International Headquarters.

Load ratings from aastm kN to kN 5, lbf tolbf Jaws move astj in stationary position while grip body moves on adjustment Works well with round or flat specimens. Load ratings from kN to kN 22, lbf tolbf Best for higher force requirements. Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend.

It is the responsibility of the user of this standard to establish appro1 This test method is under the satm of ASTM Committee D14 on Adhesives and is the direct responsibility of Subcommittee D Unless otherwise agreed upon by the manufacturer and the purchaser, the bonding conditions shall be prescribed by the manufacturer of the adhesive.

Do this by grinding the adhesive-faced surface?

Adhesion failure refers to the lack of adhering to metals being fastened. However, it does have application as a discriminator in determining variations in adherend surface preparation parameters and adhesive environmental durability. Users of this standard are expressly advised that determination of the validity of any such patent rights, and the risk of infringement of such rights, are entirely their own responsibility. It should be stated whether this temperature is that of the bond line, or of the atmosphere at which the assembly is to be maintained.

A superscript epsilon e indicates an editorial change since the last revision or reapproval.

ASTM D is primarily comparative. Describe the method of obtaining the thickness of the adhesive layer including procedure, location of measurements, and range of measurements.

ASTM D897 Tensile Strength Test Equipment for Metal to Metal Adhesive Bonds

A range may be prescribed for any variable by the manufacturer of the adhesive if it can be assumed by the test operator that any arbitrarily chosen value within such a range or any combination of such values for several variables will be acceptable to both the manufacturer and the purchaser of the adhesive. A number in parentheses indicates the ast, of last reapproval. ASTM D determines comparative qstm properties of the adhesive bonds of metal to metal. Load ratings of 20 kN and 50 kN 4, lbf and 11, lbf Maximum specimen thickness of 16 mm 0.

That is, if the cement has adhered to the metal test pieces and no voids are visual, it represents a percent cohesive failure. However, it does have application as a discriminator in determining variations in adherend surface preparation parameters and adhesive environmental durability.

It is preferable to grind all metal specimens at the same time. Use the self-aligning type. Force range of 5 kN to kN 1, lbf tolbf Adjustable test space The most popular choice for static tension and compression tests These dual column testers are available in both tabletop and floor standing models.

Start test loading of the specimen as quickly as possible. Forces up to 10 kN 2, lbf Low force tabletop systems Modular series of five frame options with adjustable test space Affordable testing option for tension, compression, bend, peel and much more.

By means of our adhesive testing expertise and modular product design, we will help find the testing solution that is right for you. The grips shall be attached to the? Asgm will be based on a visual inspection.
