Standard Guide for Use of Adhesive-Bonded Single Lap-Joint Specimen Test Results
ASTM D4896-01
Organization:
ASTM - ASTM International
Year: 2024
Abstract: 4.1 Single-lap specimens are economical, practical, and easy to make. They are the most widely used specimens for development, evaluation, and comparative studies involving adhesives and bonded products, including manufacturing quality control. 4.2 Special specimens and test methods have been developed that yield accurate estimates of the true shear strength of adhesives. These methods eliminate or minimize many of the deficiencies of the thin-adherend single-lap specimens, but are more difficult to make and test. (See Test Methods D3983, D4027, D4562, and E229.) 4.3 The misuse of strength values obtained from such Test Methods or Practices as D906, D1002, D1144, D1151, D1183, D1780, D2294, D2295, D2339, D3163, D3164, D3165, D3434, D3528, D3632, and D5868, as allowable design-stress values for structural joints could lead to product failure, property damage, and human injury.

| scope | 1.1 This guide is directed toward the safe and appropriate use of strength values obtained from test methods using single-lap adhesive joint specimens. 1.2 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. 1.3 The discussion focuses on shear strength as measured with small thin-adherend, single-lap specimens. Many factors, however, apply to shear modulus, tensile strength, and tensile modulus measured by small laboratory specimens in general. This discussion is limited to single-lap specimens and shear strength only for simplification. 1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee. | |
