Standard Test Method for Humidity Calibration (or Conformation) of Humidity Generators for Use with Thermogravimetric Analyzers — 5 стр.
Значение и использование

This test method calibrates or demonstrates conformity of the humidity level in a purge gas generated by a humidity generator at a fixed temperature. Such calibration or demonstration of conformity may be required by quality initiatives.

Conformance demonstrates that the humidified purge gas is within some established limits.

Calibration provides an offset and or slope value that may be used for establishing the relative humidity scale of the apparatus.

Область применения

1.1 This test method describes the humidity calibration (or conformance) of humidity generators for use with thermogravimetric analyzers and other thermal analysis apparatus. The humidity range covered is 5 to 95 % relative humidity (%RH) and the temperature range is 0 to 80 °C.

1.2 The values stated in SI units are to be regarded as the standard.

1.3 There are no ISO equivalents to this 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.
