Standard Test Method for Storage Modulus Calibration of Dynamic Mechanical Analyzers

Fecha:
2018-08-21 /Active
Significance and Use:

5.1 This test method calibrates or demonstrates conformity of a dynamic mechanical analyzer at an isothermal temperature within the range of –100 °C to 300 °C.

5.2 Dynamic mechanical analysis experiments often use temperature ramps. This method does not address the effect of that change in temperature on the storage modulus.

5.3 A calibration factor may be required to obtain corrected storage modulus values.

5.4 This method may be used in research and development, specification acceptance, and quality control or assurance.

Scope:

1.1 This test method describes the calibration or performance confirmation for the storage modulus scale of a commercial or custom built dynamic mechanical analyzer (DMA) over the temperature range of –100 °C to 300 °C using reference materials in the range of 1 GPa to 200 GPa.

1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

1.3 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
