- Scope
- This document specifies the test method for adjusting a closed container with a volume less than 200dm3 to achieve constant relative humidity at a given temperature by using saturated saline solution, glycerol/water solution or sulfuric acid solution, and also specifies the adjustment requirements that can be maintained at the relevant standard state at a specific temperature method within the range of deviation. This document applies to the conditioning of a small amount of material and also to tests that can be performed in small closed containers, such as electrical tests. This document does not apply to closed containers that need to be opened frequently.
