Plastics. Small enclosures for conditioning and testing using aqueous solutions to maintain the humidity at constant value1 Scope This International Standard establishes guidelines for the construction and use of enclosures with volumes less than 200 dm3, in order to obtain atmospheres of constant relative humidity at given temperatures, using saturated aqueous salt solutions, glycerol water solutions or sulfuric acid water solutions, for conditioning and testing plastics. It specifies the procedures to be followed to maintain the relative humidities of the conditioning

This part of IEC 61191 also includes recommendations for good manufacturing processes
