(Practice)Standard Practice for Description of Thermal Analysis and Rheology Apparatus
Standard Practice for Description of Thermal Analysis and Rheology Apparatus
SIGNIFICANCE AND USE
Section 5 identifies essential instrumentation and accessories required to perform thermal analysis or rheometry for a variety of different instruments. The appropriate generic instrument description should be included in any test method describing use or application of the thermal analysis or rheometry instrumentation described herein.
Units included in these descriptions are used to identify needed performance criteria and are considered typical. Other units may be used when including these descriptions in a specific test method. Items underlined constitute required inputs specifically established for each test method (for example, sensitivity of temperature sensor).
Additional components and accessories may be added as needed, with the appropriate performance requirements specified. Items listed in these descriptions but not used in a test method (for example, vacuum system) may be deleted.
SCOPE
1.1 This practice covers generic descriptions of apparatus used for thermal analysis or rheometry measurements and its purpose is to achieve uniformity in description of thermal analysis and rheometry instrumentation throughout standard test methods. These descriptions are intended to be used as templates for inclusion in any test method where the thermal analysis instrumentation described herein is cited.
1.2 Each description contains quantifiable instrument performance requirements to be specified for each test method.
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 and health practices and determine the applicability of regulatory limitations prior to use.
