ASTM D – TENSILE PROPERTIES OF ADHESIVE BONDS
Metals conforming to the following ASTM speci? It is preferable to grind all metal specimens at the same time. The values given in parentheses are for information only.
Reuse of the specimens is allowed by resurfacing those surface areas that contained the adhesive. However, it does have application as a discriminator in determining variations in adherend surface preparation parameters and adhesive environmental durability. ASTM D determines comparative tensile properties of the adhesive bonds of metal to metal.
Your d879 will receive careful consideration at a meeting of the responsible technical committee, which you may attend. The ASTM International takes no position respecting the validity of any patent rights asserted in connection with any item mentioned in this standard.
ASTM D897 Tensile Strength Test Equipment for Metal to Metal Adhesive Bonds
Start test loading of the specimen as quickly as possible. This standard has been approved for use by agencies of the Department of Defense. Contact failure refers to lack of glue lines being in contact due to uneven surfaces, poor pressure distribution, etc. Describe the method of obtaining the thickness of the adhesive layer including procedure, location of measurements, and range of measurements.
Originally published as D — While the design of grips of this type is optional, one that has been found satisfactory is shown in Fig. Test a substitute specimen to replace the discarded result. 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.
However, it does have application as a discriminator in determining variations in adherend surface preparation parameters and adhesive environmental durability. This standard is subject to revision at any time by the responsible technical committee and must be reviewed every? Do this by grinding the adhesive-faced surface? ASTM D e1. 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 adhesive itself. Individual reprints single or multiple copies of this standard may be obtained by contacting ASTM at the above address or at phonefaxor service astm. 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.
Adhesion failure wstm to the lack of adhering to metals being fastened. Unless otherwise agreed upon by the manufacturer and the purchaser, the bonding conditions shall be prescribed by the manufacturer of the adhesive.
That is, if the cement has adhered to the metal test pieces and no voids are visual, it represents a percent cohesive failure. ASTM D is primarily comparative. A superscript epsilon e indicates an editorial change ashm the last revision or reapproval.
Instron Adhesive Bond Tension – Instron
Load ratings from kN to kN 22, lbf tolbf Best for higher force requirements. Last previous edition D — We are confident that we have what you are looking for.
The test method has found applications in controlling surface preparations, primer, and adhesive atsm for determining strength properties of tested systems. Use the self-aligning type. Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM International Headquarters.
