ASTM D429 is a testing specification that includes eight test methods for testing the static adhesion strength of rubber to rigid materials. Methods A, B, C, D, and E are used for obtaining comparative adhesion test data and Methods A, B, C, and D are applicable to testing end products in which rubber is used for controlling vibration.
Method A: Rubber part assembled between two parallel metal plates- Determines adhesion values and test the effectiveness of different processing techniques and different adhesive systems.
Method B: 90 degree stripping test – Rubber part assembled to one metal plate- Determines the adhesive strength of rubber-to-metal bonding agents.
Method C: Measuring adhesion of rubber-to-metal with a conical specimen- Provides data for the development and control of bonding systems and components.
Method D: Adhesion test: Post-vulcanization (PV) of bonding of rubber to metal- Determines the strength of adhesion of rubber to metal when the bond is formed after rubber has been vulcanized.
Method E: 90 degree stripping test- Rubber tank lining- assembled to one metal plate- Determines the adhesive strength of rubber tank lining to tank wall.
Method F: Rubber part assembled between two parallel convex-shaped metal plates- Determines the adhesive strength of rubber-to-metal bonding agents.
Method G: Measuring bond durability for rubber-to-metal bonded components with a double shear cylindrical specimen- Determines the relative bond durability between various adhesives.
Method H: Measuring bond durability of rubber-to-metal bonded components with quadruple lap shear specimen- Same as Method G except that no fixture imparting the shear stress is required, only a simple block inserted into the test piece once the pre-strain has been applied.
Before conducting ASTM D429, it is important to read the entire specification in the relevant ASTM publication.
