Give one of our application engineers a call today for help with creating the best budget and testing plan according to ASTM D Load ratings from kN to kN 22, lbf tolbf Best for higher force requirements. This standard has been approved for use by agencies atm the Department of Defense.

The test method has found applications in controlling surface preparations, primer, and adhesive systems for determining strength properties of tested systems. Express the result ast, grams per square millimetre pounds per square inch and if possible report to three signi? Asrm D e1. Reuse of the specimens aatm allowed by resurfacing those surface areas that contained the adhesive. 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 — Unless otherwise agreed upon by the manufacturer and the purchaser, the bonding conditions shall be prescribed by the manufacturer of the adhesive.

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.

Load ratings of 20 kN and 50 kN 4, lbf and 11, lbf Maximum specimen thickness of 16 mm 0. We are confident that we have what you are looking for. However, it does have application as a discriminator in determining variations in adherend surface preparation parameters and adhesive environmental durability.

ASTM D is primarily comparative. A range may be prescribed for any variable by the manufacturer of the adhesive if it can be assumed by the ast, 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 wstm the purchaser of astn adhesive.

While the design of grips of this type is optional, one that has been found satisfactory is shown in Fig. 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.

Metals conforming to the following ASTM speci? Have a question about conducting the test for this standard? NOTE 1—Cohesive failure may be obtained by observing how much of the failure has occurred in the adhesive itself.

Do this by grinding the adhesive-faced surface? Start test loading of the specimen as quickly as possible. This standard is subject to revision at any time by the responsible technical committee and must be reviewed every? The values given in parentheses are for information only.

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 e897lbf Jaws move laterally in stationary position while grip body moves on adjustment Works well with round or flat specimens.

ASTM D determines comparative tensile properties of the adhesive bonds of metal to metal. If you feel that your astk have not received a fair hearing you should make your views known to the ASTM Committee on Standards, at the address shown below. Precision and Bias 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, asttm and much more.

Adhesion failure refers to the lack of adhering to metals being fastened. Use the self-aligning type. Force range of 5 kN to kN 1, lbf tolbf Adjustable test space The most popular choice for qstm tension and compression tests These dual column testers are available in both tabletop and floor standing models.

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.

That is, if the cement has adhered to the metal test pieces and no voids are visual, it represents a percent cohesive failure. Describe the method of obtaining the thickness of the adhesive layer including procedure, location of measurements, and range of measurements.
