ASTM D3164-03

Standard Test Method for Strength Properties of Adhesively Bonded Plastic Lap-Shear Sandwich Joints in Shear by Tension Loading

SIGNIFICANCE AND USE
Due to the increased use of adhesively bonded plastics as a result of the inherent advantages afforded by bonded rather than mechanically fastened joints, particularly the alleviation of stress risers and stress cracking, there is a need for standard tests by which joints of various substrates and adhesives can be compared. This test method is intended to meet such a need.
This test method is limited to test temperatures below the softening point of the subject adherends, and is not intended for use on anisotropic adherends such as reinforced plastic laminates.
The misuse of strength values obtained from this test method as design stress allowable values for structural joints could lead to product failure, property damage, and human injury.
The apparent shear strength of an adhesive obtained from a given small single-lap specimen may differ from that obtained from a joint made with different adherends or by a different bonding process. The normal variation of temperature and moisture in the service environment causes the adherends and the adhesive to swell and shrink. The adherends and adhesive are likely to have different thermal and moisture coefficients of expansion.
Even in small specimens, short-term environmental changes can induce internal stresses or chemical changes in the adhesive that permanently affect the apparent strength and other mechanical properties of the adhesive. The problem of predicting joint behavior in a changing environment is even more difficult if a different type of adherend is used in a larger structural joint than was used in the small specimen.
The apparent shear strength measured with a single-lap specimen is not suitable for determining allowable design stresses for designing structural joints that differ in any manner from the joints tested without thorough analysis and understanding of the joint and adhesive behaviors.
Single-lap tests may be used for comparing and selecting adhesives or bonding processes for susceptib...
SCOPE
1.1 This test method is intended to complement Test Method D 1002 and Test Method D 3163 and extend its application to single-lap-shear adhesive joints employing plastic adherends. The test method is useful for generating comparative shear strength data for joints made from a number of plastics. It can also provide a means by which several plastics surface treatments can be compared.
1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.
Note 1—A complete metric companion to Test Method D 3164 has been developed - D 3164M.
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.
