Scope

This document specifies a test method for adjusting the relative humidity of a sealed container with a volume of less than 200 dm3 to a constant level using saturated brine solutions, glycerol/water solutions, or sulfuric acid solutions at a given temperature. It also stipulates a method for maintaining the deviation range within the relevant standard adjustment requirements at a specific temperature.
This document is applicable to the state adjustment of small amounts of materials and to tests that can be conducted in small sealed containers, such as electrical tests.
This document is not suitable for sealed containers that need to be opened frequently.
