Liquefied petroleum gas and light hydrocarbons. Determination of density or relative density. Pressure hydrometer method Ingestion-build-100580 Number of testsWhat is BS 3993: 1966? BS 3993 specifies two types of hydrochloric acid. The standard sets out the requirements for residue on evaporation, sulphated residue on ignition, total sulphate, iron, arsenic, lead, copper, mercury, oxidizing and reducing substances. It also looks at a variety of test methods. How does it work? BS 3993 first looks at the material essentially a liquid solution of hydrogen chloride, HCI. This should be clear, ranging from
