Give one of our d8977 engineers a call today for help with creating the best budget and testing plan according to ASTM D Adhesion failure refers to the lack of adhering to metals being fastened. It is preferable to grind all metal specimens at the same time. A superscript epsilon e indicates an editorial change since the last revision or reapproval.

Contact failure refers to lack of glue lines being in contact due to uneven surfaces, poor pressure distribution, etc. Have a question about conducting the test for this standard? ASTM D is primarily comparative. However, it does v897 application as a discriminator in determining variations in adherend surface preparation parameters and adhesive environmental durability.

Unless otherwise agreed upon by the manufacturer and the purchaser, the bonding conditions shall be prescribed by the manufacturer of the adhesive.

Adhesive Bond Tension Test Fixture

Reuse of the specimens is allowed by resurfacing those surface areas that contained the adhesive. 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. 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.

Load ratings from 25 kN to kN 5, lbf tolbf Jaws move laterally in stationary position while grip body moves on adjustment Works well with round or flat specimens.

ASTM D – TENSILE PROPERTIES OF ADHESIVE BONDS

By means of our adhesive testing expertise and modular product design, we will help find the testing solution that is right for you. A number in parentheses indicates the year of last reapproval. NOTE 1—Cohesive failure may be obtained by observing how much of the failure has occurred in the astk itself.

The grips shall be attached to the? This will be based on a visual inspection. We are confident that we have what you are looking for. G Mechanical Wedge Grip.

That is, if the cement has adhered to the metal test pieces and no voids are visual, it represents a percent cohesive failure. Last previous edition D — Individual reprints single or multiple copies of this standard may be obtained by contacting ASTM at ast, above address or at phonefaxor service astm.

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

Load ratings of 20 kN and 50 kN 4, lbf and 11, lbf Maximum specimen thickness of 16 mm 0. Load ratings from kN to kN 22, lbf toast, Best for higher force requirements. 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.

The test method has found applications in controlling surface preparations, primer, and adhesive systems for determining strength properties of tested systems. However, it does zstm application as a discriminator in determining variations in adherend surface preparation parameters and adhesive environmental durability. Current edition approved Oct.

Describe the method of obtaining the thickness of the adhesive layer including procedure, location of measurements, and range of measurements.

Precision and Bias ASTM D determines comparative tensile properties of the adhesive bonds of metal to metal. In order to ensure that complete information is available to the individual conducting the tests, the manufacturer of the adhesive shall furnish numerical values and other speci?
