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.

It is the responsibility of the user of this standard asttm establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. In actual use, lack of temperature equilibrium relative humidity; equilibrium relative humidity; hu-midity; 0.

Users of this standard are expressly advised that determination of the validity of any such patent rights, and the risk of infringement of such rights, are entirely their own responsibility. There is also the erated using selected aqueous saturated salt solutions or possibility of corrosive vapors in the atmospheres over the various strength sulfuric acid-water systems. For more specific safety precautionary information see 1. The hydrometer s should have a mini- acid solutions should be regarded as hazardous materials.

Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM International Headquarters.
