This will be based on a visual inspection. The ASTM International takes no position respecting the validity of any patent rights asserted in connection with any item mentioned in this standard.

Current edition approved Oct. The values given in parentheses are for information only. We are confident that we have what you are looking for. NOTE 1—Cohesive failure may be obtained by observing how much of the failure has occurred in the adhesive itself.

Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend. 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. 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.

However, it does have application as a discriminator in determining variations in adherend surface preparation parameters and adhesive environmental durability. Have a question about conducting the test for this standard?

Use the self-aligning type.

ASTM D is primarily comparative. 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. While the design of grips of this type is optional, one that has been found satisfactory is shown in Fig. Contact failure refers to lack of glue lines being in contact due to uneven surfaces, poor pressure distribution, etc.

Load ratings of 20 kN and 50 kN 4, lbf and 11, lbf Maximum specimen thickness of 16 mm 0. Do this by grinding the adhesive-faced d97 Reuse of the specimens is allowed by resurfacing those surface areas that sstm the adhesive. ASTM D e1. We offer machines, apparatus, testers, tensile grips, test fixtures, clamps, holders, jigs, faces, jaws, extensometers, environmental and humidity chambers, furnaces, baths and custom solutions for unique applications.

Describe the method of obtaining the thickness of the adhesive layer including procedure, location of measurements, and range of measurements.

Astj number in parentheses indicates the year of last reapproval. A superscript epsilon e indicates an editorial change since the last revision or reapproval. Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM International Headquarters.

Unless otherwise agreed upon by the manufacturer and the purchaser, the bonding conditions shall be prescribed by the manufacturer of the adhesive.

Test a substitute specimen to replace the discarded result. Express the result in grams per square millimetre pounds per square inch and if possible asstm 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.

ASTM D determines comparative tensile properties of the adhesive bonds of metal to metal.

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.

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? Load ratings from kN to kN 22, lbf tolbf Best for higher force requirements.

Originally published as D — 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. It is preferable to grind all metal specimens at the same time.

Start test loading of the specimen as quickly as possible. 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 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.
