Interpretation of the National Standard of the People's Republic of China GB/T 13936-2014

Comparison and interpretation of standard frameworks

Implementation suggestions and precautions

1. Equipment selection: Use a tensile testing machine that complies with GB/T 17200 to ensure that the force measurement accuracy meets the requirements. For high-precision testing, it is recommended to use equipment with an error of less than or equal to ±1%.

2. Material preparation: Select appropriate metal sheets and rubber sheets according to the recommended materials, and strictly prepare the specimens according to the standard size. Pay attention to avoid surface contamination and bonding surface misalignment exceeding 0.2mm.

3. Environmental control: The test should be carried out in an environment with a temperature of (23±2)℃ and a humidity of (50±5)%. For highly sensitive adhesives, special attention should be paid to humidity control.

4. Data recording: Record the maximum load, failure type, and use three significant digits to express the results when calculating the tensile shear strength. At the same time, the influence of the failure type on the bonding performance needs to be analyzed.

Explanation of professional terms

• Tensile testing machine: Professional equipment used to measure the load and failure point of materials when stretched.
• Bond surface misalignment: Refers to the surface position deviation when the metal sheet and the rubber sheet are bonded, which must be controlled within 0.2mm to ensure the accuracy of the test.
• Cohesive failure: The type of failure caused by the internal fracture of the adhesive, reflecting the insufficient performance of the adhesive.
