ASTM D429 PDF
ASTM D determines the adhesion strength of rubber to rigid materials, such as metals. The standard requires that the testing machine conform to practices. This standard is issued under the fixed designation D ; the 1 These test methods are under the jurisdiction of ASTM Committee D11 on. This standard is issued under the fixed designation D ; the number These test methods are under the jurisdiction of ASTM Committee D11 on For.

To prepare ashm specimens for Method D, 6 rubber pucks are mounted in an assembly with a clamp to hold compressive force. The challenges of testing to this standard: Once the samples have cooled, clamp the bonded assembly to the tension testing machine using tensile grips. Users of previous versions of software such as Bluehill 2 and Bluehill 3 can easily upgrade to the newest version of Bluehill.
Concrete, Asphalt and Rock. How can we help you?
ASTM D429 Rubber Property – Adhesion to Rigid Substrates
Place the tab in the grip and apply a steady load at the rate of 50 mm 2. Either the rubber material fails internally or at the adhesion surface to the metal.
The sample also lends itself to testing the effectiveness of asrm processing techniques and various adhesive systems.
Method B of ASTM D is intended to determine the adhesive strength of rubber to metal bonding agents by 90 degree peel strip test.

This will help avoid slipping in the test. Software for Series Systems.
Users of previous versions of software such as Bluehill 2 and Bluehill 3 can easily upgrade to the newest version of Bluehill.
Prepare the rubber specimen for this test by vulcanizing it to the metal material of the tank. Peel fixtures provide a condition of use to measure the bond strength between laminated surface coatings, films, packaging, asmt their rigid backings, as well as other bonded structures.
A shear test is done until a break occurs at a depth of 5 mm at the rubber-metal bond interface. Secrets of Reliable Testing. This ensures that the line of tensile force remains concentric with the grip body. Samples for Method A are cylinder assemblies consisting of a cylinder of rubber 3.
Peel fixtures provide a condition of use to measure the bond strength between laminated surface coatings, films, packaging, and their rigid backings, as well as other bonded structures. The standard calls out several test types related to rubber adhesion c429 however, Methods A and B are the most common.

Works very well with flat, thin specimens Eccentric design increases gripping force with tension. Record the total load at the time of failure. Next Checking to see if you ast, a returning visitor…. Rubber is typically bonded to metal during the vulcanizing or heating process, but this method is for glue or other materials that are used after the rubber is made via vulcanizing.
We highly recommend not using deadweights as those are outdated methods of retrieving data. D42 A describes a tension test used to determine the bond of a rubber part assembled between two parallel metal plates. Test Method C of ASTM D helps determine the adhesive strength of rubber-to-metal bonding agents when applied to conical or cone-shaped samples.

Common application examples that use tests in ASTM D are vehicle engine mounts, vehicle suspension bushings, rubber-coated metal parts, and rubber-lined tanks and containers.
How can we help you? Pneumatic grips also provide constant clamping force throughout the test to avoid specimen slippage. The metal pieces are made with tabs on the backsides for gripping in the test machine. Have a question about conducting the test for this standard?
