Standard Test Method for Impact Strength of Adhesive Bonds (Withdrawn 2003)

SCOPE
1.1 This test method covers the determination of the comparative impact strength of adhesive bonds in shear, when tested on standard specimens under specified conditions of preparation, conditioning, and testing.  
1.2 The values stated in SI units are to be regarded as the standard. The values in parentheses are for information only.  
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

This standard is issued under the fixed designation D 950; the number immediately following the designation indicates the year of
original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A
superscript epsilon (e) indicates an editorial change since the last revision or reapproval.
This standard has been approved for use by agencies of the Department of Defense.
INTRODUCTION
The accuracy of the results of strength tests of adhesive bonds will depend on the conditions under
which the bonding process is carried out. Unless otherwise agreed upon between the manufacturer and
the purchaser, the bonding conditions shall be prescribed by the manufacturer of the adhesive. 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 specific information for each of
the following variables:
(1) Procedure for preparation of surfaces prior to application of the adhesive, including the
moisture content of wood, the cleaning and drying of metal surfaces, and special surface treatments
such as sanding which are not specifically limited by the pertinent test method.
(2) Complete mixing directions for the adhesive.
(3) Conditions for application of the adhesive including the rate of spread or thickness of film,
number of coats to be applied, whether to be applied to one or both surfaces, and the conditions of
drying where more than one coat is required.
(4) Assembly conditions before application of pressure, including the room temperature, length of
time, and whether open or closed assembly is to be used.
(5) Curing conditions, including the amount of pressure to be applied, the length of time under
pressure and the temperature of the assembly when under pressure. 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.
(6) Conditioning procedure before testing, unless a standard procedure is specified, including the
length of time, temperature, and relative humidity.
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.
