ASTM D Standard Test Method for Tensile Properties of Adhesive Bonds. ASTM D determines comparative tensile properties of the adhesive bonds of metal to metal. ASTM D is primarily comparative. However, it does have. ASTM D TENSILE PROPERTIES OF ADHESIVE BONDS. This test method covers the determination of the comparative tensile properties of the adhesive.

It is preferable to grind all metal specimens at the same time.
While the design of grips of this type is optional, one that has been found satisfactory is shown in Fig. The test method has found applications in controlling surface preparations, primer, and adhesive systems for determining strength properties of tested systems.
This standard has been approved for use by agencies of the Department of Defense. This standard is subject to revision at any time by the responsible technical committee and must be reviewed every? 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 d879 with round or flat asm.
NOTE 1—Cohesive failure may be obtained asttm observing how much of the failure has occurred in the adhesive itself.
The values given in parentheses are for information only. 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 d8977 acceptable to both the manufacturer and the purchaser of the adhesive.
A superscript epsilon e indicates an editorial change since the last revision or reapproval. Give one of our application engineers a call today for help with creating the asym budget and testing plan according to ASTM D Describe the method of obtaining the thickness of the adhesive layer including procedure, location of measurements, and range of measurements.
If you feel that your comments have not received a fair hearing you should make your views known to the ASTM Committee on Standards, at the address shown below. Force range of 5 kN to kN 1, lbf tolbf Adjustable test space The most popular choice for static tension asfm compression tests These dual column testers are available in both tabletop and floor standing models.
Use the self-aligning type.
Metals conforming to the following ASTM speci? 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? However, it does have application as a discriminator in determining variations in adherend surface preparation parameters and adhesive environmental durability.
Current edition approved Oct. Have a question about conducting the test for this standard? 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.
It is the responsibility of the user of this standard to establish appro1 This test method is under the jurisdiction of ASTM Committee D14 on Adhesives and is the direct responsibility of Subcommittee D A number in parentheses indicates the year of last reapproval.
ASTM D determines comparative tensile properties of the adhesive bonds of metal to metal. Reuse of the specimens is allowed by resurfacing those surface areas that contained the adhesive. We offer machines, apparatus, testers, tensile grips, test fixtures, clamps, holders, jigs, faces, jaws, extensometers, environmental and humidity satm, furnaces, baths and custom solutions for unique applications.
Start test loading of the specimen as quickly as possible. It should axtm stated whether this temperature is that of the bond line, or of the atmosphere at which the assembly is to be maintained. This will be based on a visual inspection. We are confident that we have what you are looking for. Express the result in grams per square millimetre pounds per square inch and if possible report to three signi?
That is, if the cement has adhered to the metal test pieces and no voids are visual, it represents a percent cohesive failure. The ASTM International takes no position astk the validity of any patent rights asserted in connection with any item mentioned in this standard. G Mechanical Wedge Grip. Individual reprints single or multiple copies of this standard may be obtained by contacting ASTM at the above address or at phonefax s897, or service astm.
However, it does have application as a discriminator in determining variations in adherend surface preparation parameters and adhesive environmental durability. By means of our adhesive testing expertise and modular product design, we will help find the testing solution that is right for you.
Load ratings from kN to kN 22, lbf tolbf Best for higher force requirements. The grips shall be attached to the? Unless otherwise agreed upon by the manufacturer and the purchaser, the bonding conditions shall be prescribed by the manufacturer of the adhesive.
