Type I solvent is intended for use in the cleaning of space vehicle components, precision assemblies, oxygen systems and electronic equipment by the processes of spraying, flushing, vapor degreasing, or ultrasonics. The solvent is especially applicable for cleaning precision parts and assemblies in clean rooms and for use as a medium in testing the cleanliness of components that are assumed to be clean.

Types II and IIA are used when the requirements for purity and cleanliness are less stringent than those of a cleaning process using Type I solvent. Since solvent vapors are purer than the liquid which evolves them, Type II solvent is particularly suitable for vapor degreasing processes.
