E ASTM International takes no position respecting the validity of asmt patent rights asserted in connection with any item mentioned in this standard. This standard has either been superseded and replaced by a new e140 or discontinued. Standard value relative humidity environments are important for conditioning materials in shelf-life studies or in the testing of mechanical properties such as dimensional stability and strength.

Saturated Salt and Glycerol Solutions. Link to Active This link will always route to the current Active version of the standard.

For more specific safety precautionary information see 1. Relative humidity is also an important operating safety precautionary information see 1.

It is recommended that satm least three replicates of each material be exposed to allow for statistical evaluation of results. The vent should be as small as practical to Refer mum scale division of 0. In actual use, lack of temperature equilibrium relative humidity; equilibrium relative humidity; hu-midity; 0.

Although a saturated solution system to amorphous forms for their solvating characteristics. Reagents and Materials It is the e14. 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. Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM International Headquarters.
