Load ratings from kN to kN 22, lbf tolbf Best for higher force requirements. However, it does have application as a discriminator in determining variations in adherend e897 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.
We are confident that we have what you are looking for. A superscript epsilon e indicates an editorial change since the last revision or reapproval. 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. Originally published as D — A number in parentheses indicates the year of last reapproval. Give one of our application engineers a call today for help with creating the best budget d89 testing plan according to ASTM D Do this by grinding the adhesive-faced surface?
This standard is subject to revision at any time by the responsible technical committee and must be reviewed every?
ASTM D – 08() Standard Test Method for Tensile Properties of Adhesive Bonds
Precision and Bias Contact failure refers to lack of glue lines being in contact due to uneven surfaces, poor pressure distribution, etc. G Mechanical Wedge Grip.
Reuse of the specimens is allowed by resurfacing those surface areas that contained the adhesive. Use the self-aligning type. While the design of grips of this type is optional, one that has been found satisfactory is shown in Fig.
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.
Load ratings d97 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.
Test a substitute specimen to replace the discarded result. Have a question about conducting the test for this standard? Describe the method of obtaining the thickness of the adhesive layer including procedure, location of measurements, and range of measurements.
It is preferable to grind all metal specimens at the same time. By means of our adhesive testing expertise and modular product design, we will help find the d879 solution that is right for you.
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.
Adhesive Bond Tension Test Fixture
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. That is, if the cement has adhered to the metal test pieces and no voids are visual, it represents a percent cohesive failure.
Metals conforming to the following ASTM speci? Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM International Headquarters. The test method has found applications in controlling surface preparations, primer, and adhesive systems for determining strength properties of tested systems.
Individual reprints single or multiple copies of this standard may be obtained by contacting ASTM at the above address r897 at phonefaxor service astm.
Last previous edition D — Adhesion failure refers to the lack of adhering to metals being fastened. Load ratings of 20 kN and 50 kN 4, lbf and 11, lbf Maximum specimen thickness of 16 mm 0.
Start test loading of the specimen as quickly as possible. 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.
ASTM D897 Tensile Strength Test Equipment for Metal to Metal Adhesive Bonds
In order d879 ensure that complete information is available to the individual conducting the tests, the manufacturer of the adhesive shall furnish numerical values and other speci? Current edition approved Oct. Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend.
However, it does have application as a discriminator in determining variations in adherend surface preparation parameters and adhesive environmental durability. The grips shall be attached d8897 the? This standard has been approved for ast, by agencies of the Department of Defense.
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 f897 available in both tabletop and floor standing models. ASTM D is primarily comparative. This will be based on a visual inspection. Express the result in grams per square millimetre pounds per square inch and if possible report to three signi? ASTM D determines comparative tensile properties of the adhesive bonds of metal to metal.
