ASTM E1363-97e1

Standard Test Method for Temperature Calibration of Thermomechanical Analyzers

SCOPE
1.1 This test method covers the temperature calibration of thermomechanical analyzers from -50 to 1100°C. (See Note 2.)  
1.2 Computer or electronic based instruments, techniques, or data treatment equivalent to this test method may be used.  
Note 1-Users of this test method are advised that all such instruments or techniques may not be equivalent. It is the responsibility of the user of this test method to determine the necessary equivalency prior to use.  
1.3 The values stated in SI units are to be regarded as the standard.  
1.4 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. Specific precautionary statements are given in Section 9 and Note 9.
