(Test Method)Standard Test Method for Floating Roller Peel Resistance of Adhesives
Standard Test Method for Floating Roller Peel Resistance of Adhesives
SCOPE
1.1 This test method covers the determination of the relative peel resistance of adhesive bonds between one rigid adherend and one flexible adherend when tested under specified conditions of preparation and testing.
1.2 A variation in thickness of the adherends will generally influence the test values. For this reason, the thickness of the sheets used to make the test specimens shall be specified in the material specification. When no thickness is specified, the flexible adherend shall be 0.63 mm (0.025 in.) thick and the rigid adherend shall be 1.63 mm (0.064 in.) thick.
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 .

Standard Test Method for
Floating Roller Peel Resistance of Adhesives
This standard is issued under the fixed designation D 3167; 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.
INTRODUCTION
The purpose of this test method is to provide for the determination of the metal-to-metal peel
strength of adhesives by a method that will provide good reproducibility at low-, as well as at
highstrength levels and yet allow for a simple method of test specimen preparation and testing.
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 the surfaces prior to application of the adhesive, 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 and length
of time.
(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 glue 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.
