Standard value relative humidity environments are important for conditioning materials in shelf-life studies or in the testing of mechanical asgm such as dimensional stability and strength. Hydrated reagents are often preferred evidenced by free liquid. There is also the possibility of corrosive vapors in the atmospheres over the saturated salt solutions. Refer also to 9.

Relative humidity is also an important operating variable for the calibration e1044 many species of measuring instruments. The reference document by Greenspan9 contains information 8.

A superscript epsilon indicates an editorial change since the last revision or reapproval. 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. Relative humidity is also an important operating variable for the calibration of many species of measuring instruments.
