Historical Standard: ASTM D3762-98 Standard Test Method for Adhesive-Bonded Surface Durability of Aluminum (Wedge Test)
SUPERSEDED (see Active link, below)
ASTM D3762
1. Scope
1.1 This test method 2,3 simulates in a qualitative manner the forces and effects on an adhesive bond joint at metal-adhesive/primer interface. It has proven to be highly reliable in determining and predicting the environmental durability of adherend surface preparations. The method has proven to be correlatable with service performance in a manner that is much more reliable than conventional lap shear or peel tests (Note 2).
Note 1-While this test method is intended for use in aluminum-to-aluminum applications it may be used for determining surface durability of other metals and plastics provided consideration is given to thickness and rigidity of the adherends. Note 2-This test method is not a quantitative fracture strength test method. To measure fracture strength see Practice D3433.1.2 This standard does not purport to address all of the safety problems, 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.
