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

Adhesion failure refers to the lack of adhering to metals being fastened. Users of this standard are expressly advised that determination of the validity of any such patent rights, s897 the risk of infringement of such rights, are entirely their own responsibility.

Last previous edition D — Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend. 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 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. While the design of grips of astmm type is optional, one that satm been found satisfactory is shown in Fig.

Individual reprints single or multiple copies of this standard may be obtained by contacting ASTM at the above address or at phonefaxor service astm.

NOTE 1—Cohesive failure may be obtained by observing how much of the failure has occurred in the adhesive itself. The ASTM International takes no position respecting the validity of any patent rights asserted in connection with any item mentioned in this standard. Load ratings from kN to kN 22, lbf tolbf Best for higher force requirements. The grips shall be attached to the? X897 the self-aligning type.

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 asrm variables will be acceptable to both the manufacturer and the purchaser of the adhesive.

This will be based on a visual inspection. ASTM D is primarily comparative. 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? If you feel that your comments have not received a fair hearing you should make your views atsm to the ASTM Committee on Standards, at the address shown below.

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.

By means of our adhesive testing expertise and modular product design, we will help find the testing solution that is right for you. ASTM D e1. Express the result in grams per square millimetre pounds per square inch and if possible report to three signi?

A number in parentheses indicates the year of last reapproval. That is, if the cement has adhered to the metal test pieces and no voids are visual, it represents a percent cohesive failure.

The test method has found applications in controlling surface preparations, primer, and adhesive systems for determining strength properties of tested systems.

This standard is subject to revision at any time by the responsible technical committee and must be reviewed every? This standard has been approved for use by agencies of the Department of Defense.

It is preferable to grind all metal specimens at the same time. Contact failure refers to lack of glue lines being in contact due to uneven surfaces, poor pressure distribution, etc. Precision and Bias G Mechanical Wedge Grip. However, it does have 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. Metals conforming to the following ASTM speci?
