DIN 53512 - Determination of Rebound Elasticity of Rubber Using the Schob Pendulum

DIN 53512 specifies a test method for determining the rebound elasticity of rubber and elastomers. This standard evaluates the energy recovery capacity of materials subjected to impact, using the Schob pendulum device. It is commonly used for rubber materials with Shore A or IRHD hardness values between 30 and 85.

Scope

Testing Methodology

  • A rubber specimen of standard dimensions is subjected to impact using a Schob pendulum.
  • The rebound height of the pendulum is measured, and the material’s rebound elasticity is calculated as a percentage.

Applicability

  • Suitable for evaluating the dynamic behavior of elastomeric materials.
  • Can be used for automotive, construction, and consumer product applications.

Assessment Parameters

  • Measures the energy recovery efficiency of rubber under dynamic conditions.
  • Provides critical data on material flexibility and durability.

Applications

  • Material Quality Control: Ensures rubber materials meet performance standards in production.
  • Performance Testing: Evaluates the dynamic properties of elastomers under impact conditions.
  • Research and Development: Aids in developing rubber products with enhanced flexibility and durability.
