THIS SECTION INCLUDES TESTS for determining the materials of construction requirements for equipment used for manufacturing chemicals. This includes both bulk chemicals, which are typically manufactured in dedicated equipment in large quantities, and specialty chemicals, which are most often made in smaller quantities and often in equipment used for more than one process. Tests for both organic and inorganic chemicals are included. Because some tests require the presence of an electrolyte, they are not suitable for many pure organic processes. Equipment intended for use in the pharmaceutical, petrochemical, or high-temperature gas phase or molten salt processes have special requirements that are not included in this section.
