WebThe ASTMs Brinell hardness test standard is used by alloy and metal suppliers and users, and its a basic requirement for all hardness testing equipment. Most of LWRs use the uranium fuel, which is in the form of uranium dioxide (chemically UO2). Rubber moulded products are widely used industrially (and in some household applications) in the form of rubber goods and appliances. Methane is a fuel and can be used in industrial chemical processes and may be transported as a refrigerated liquid (liquefied natural gas, or LNG).
