Standard Test Methods for Rubber Properties in Compression or Shear (Mechanical Oscillograph)
| 분야 | |
|---|---|
| 적용범위 | 1.1 These test methods cover the use of the Yerzley mechanical oscillograph for measuring mechanical properties of rubber vulcanizates in the generally small range of deformation that characterizes many technical applications. These properties include resilience, dynamic modulus, static modulus, kinetic energy, creep, and set under a given force. Measurements in compression and shear are described.2,3 1.2 The test is applicable primarily, but not exclusively, to materials having static moduli at the test temperature such that forces below 2 MPa (280 psi) in compression or 1 MPa (140 psi) in shear will produce 20 % deformation, and having resilience such that at least three complete cycles are produced when obtaining the damped oscillatory curve. The range may be extended, however, by use of supplementary masses and refined methods of analysis. Materials may be compared either under comparable mean stress or mean strain conditions. 1.3 Computerized data acquisition systems and data evaluation methods for Yerzley Mechanical Oscillograph are included The mechanical portion of the oscillograph remains the same. In the computerized type (digital data acquisition and recording), the mechanical recording mechanism has been replaced with a displacement transducer and digital data acquisition system, by which the required calculations are such that the results are available immediately and recorded in real time. 1.4 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only. 1.5 This standard does not purport to address all of the safety concerns, 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. For a specific warning see 12.14. |
