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. We are confident that we have what you are looking for. This standard has been approved for use by agencies of the Department of Defense.
ASTM D is primarily comparative. Express the result in grams per square millimetre pounds per square inch and if possible report to three signi? Describe the method of obtaining the thickness of the adhesive layer including procedure, location of measurements, and range of measurements.
ASTM D – 08() Standard Test Method for Tensile Properties of Adhesive Bonds
Originally published as D — ASTM D e1. 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. While the design of grips of this type is optional, one that has been found satisfactory is shown in Fig. However, it does have application as a discriminator in determining variations in adherend surface preparation parameters and adhesive environmental durability.
Start test loading of the specimen as quickly as possible. 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. Reuse of the specimens is allowed by resurfacing those surface areas that contained the adhesive. Load ratings from kN to kN 22, lbf tolbf Best for higher force requirements. This will be based on a visual inspection. Adhesion failure refers to the lack of adhering to metals being fastened.
The test method has found applications in controlling surface preparations, primer, and adhesive systems for determining strength properties of tested systems.

Contact failure refers to lack of glue lines being in contact due to uneven surfaces, poor pressure distribution, etc. 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.
A range may be prescribed for any s897 by the manufacturer of the adhesive if it can be assumed by the d97 operator that any arbitrarily chosen value within such a range or any combination asm such values for several variables will be acceptable to both the manufacturer and the purchaser of the adhesive.
A number in parentheses indicates the year of last reapproval. Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM International Headquarters.
The values given in parentheses asm for information only. However, it does have application as a discriminator in determining variations in adherend surface preparation parameters and adhesive environmental durability. Precision and Bias Have a question about conducting the test for this standard?
Last previous edition D — 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. 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.
Load ratings of 20 kN and 50 kN 4, lbf and 11, lbf Maximum specimen thickness of 16 mm 0.
