It is preferable to grind all metal specimens at the same time.

While the design of grips of this type is optional, one that has been found satisfactory is shown in Fig. The test method has found applications in controlling surface preparations, primer, and adhesive systems for determining strength properties of tested systems.

This standard has been approved for use by agencies of the Department of Defense. This standard 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. Load ratings from 25 kN to kN 5, lbf tolbf Jaws move laterally in stationary position while grip body moves on adjustment Works d879 with round or flat asm.

NOTE 1—Cohesive failure may be obtained asttm observing how much of the failure has occurred in the adhesive itself.

The values given in parentheses are for information only. 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 d8977 acceptable to both the manufacturer and the purchaser of the adhesive.

A superscript epsilon e indicates an editorial change since the last revision or reapproval. Give one of our application engineers a call today for help with creating the asym budget and testing plan according to ASTM D Describe the method of obtaining the thickness of the adhesive layer including procedure, location of measurements, and range of measurements.
