Designation: D1002 - 10 Standard Test Method for Apparent Shear Strength of Single-Lap-Joint Adhesively Bonded Metal Specimens by Tension Loading (Metal-to Metal)1 This standard is issued under the fixed designation D1002; 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 (s) 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 by 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, the cleaning and drying of metal surfaces, and special surface treatments such as sanding that 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 flm, 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, relative humidity, 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, method of applying pressure (pressure bag, press platens, etc.), heat-up rate, and the temperature of the assembly when under pressure. It should be stated whether this temperature is that of the bondline 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. 1.
