cementmeans a finely ground inorganic material which, when mixed with water, forms a paste that sets and hardens by means of hydration reactions and processes and which, after hardening, retains its strength and stability even under water;
cementitious materialmeans a material that contains a hydraulic cement in sufficient proportion to act as the main binder by forming a hydrate structure which governs the performance of the material;
ceramic materialsmeans inorganic poly- or single crystalline, non-metallic solid materials subjected to high temperature in manufacture;
enamelmeans a material that is a vitreous material obtained by melting at temperatures higher than 1200 °C and fritting of a mixture of inorganic substances;
materialmeans a solid, semi-solid or liquid that is used for the manufacturing of a product that is:
maximum tolerable concentration at the tap(MTCtap) means the maximum permitted concentration of a substance transferred from a specific material into water intended for human consumption.
metallic materialmeans a metal or metal alloy used either in bulk form or as metallic plating;
monomermeans a substance which is capable of forming covalent bonds with a sequence of additional like or unlike molecules under the conditions of the relevant polymer-forming reaction used for the particular process;
monomer unitmeans the reacted form of a monomer substance in a polymer;
non-intentionally added speciesmeans either one of the following:
Not applicablemeans that the metal is not hazardous and no MTCtap applies.
organic cementitious constituentmeans an organic substance that is used in the manufacture of cementitious materials;
organic materialmeans a material that mainly consist of carbon-based substances;
polymermeans a substance consisting of molecules that are characterised by the sequence of one or more types of monomer units ant that are distributed over a range of molecular weights wherein differences in the molecular weight are primarily attributable to differences in the number of monomer units comprising the following:
polymerised partmeans the part of a substance composition consisting of molecules characterised by the sequence of one or more types of monomer units.
