Adhesive Bond Tension Test Fixture
Contact failure refers to lack of glue lines being in contact due to uneven surfaces, poor pressure distribution, d89. ASTM D e1. Describe the method of obtaining the thickness of the adhesive layer including procedure, location of measurements, and range of measurements.
ASTM D is primarily comparative. However, it does have application as a discriminator in determining variations in adherend asrm preparation parameters and adhesive environmental durability.
NOTE 1—Cohesive failure may be obtained by observing how much of the failure has occurred in the adhesive itself. This aetm 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. That is, if the cement has adhered to the metal test pieces and no voids are visual, it represents a percent cohesive failure. Forces up to 10 kN 2, lbf Low force tabletop systems Modular series of five frame options with awtm test space Affordable testing option for tension, compression, bend, peel and much more.
By means of our adhesive testing expertise and modular product design, we will help find the testing solution that is right for you. Last previous edition D — Precision and Bias dd897 We are confident that we have what you are looking for. 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.
Load ratings of 20 kN and 50 kN 4, lbf and 11, lbf Maximum specimen thickness of 16 mm 0. 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.
Current edition approved Oct.

The ASTM International takes no position respecting the validity of any patent rights asserted in connection with any item mentioned in this standard.
ASTM D – 08() Standard Test Method for Tensile Properties of Adhesive Bonds
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. It is preferable to grind all metal specimens at the same time. Adhesion failure refers to the lack of adhering to metals being fastened. This standard has been approved for use by agencies of the Department of Defense.

Express the result in grams per square millimetre pounds per square inch and if possible report to three signi? 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?
Reuse of the specimens is allowed by resurfacing those surface areas that contained the adhesive. The grips shall be attached to the? Load ratings from kN to kN 22, lbf tolbf Best for higher force requirements. It should be stated whether this temperature is that of the bond line, or of the atmosphere at which zstm assembly is to be maintained.

Give one of our application engineers a call today for help with creating the best budget and testing plan according to ASTM D The test method has found applications in controlling surface preparations, primer, and adhesive systems for determining strength properties of tested systems.
However, it does have application as a discriminator in determining variations in adherend surface preparation parameters and adhesive environmental durability. The values given in parentheses are for information only. This will be based on a visual inspection. Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend.
ASTM D determines comparative tensile properties of the adhesive bonds of metal to metal. Do this by grinding the adhesive-faced surface?
