3.1 shelf life
period of time starting with the completion of the production of the batch in which injection water (3.5),stored under specific conditions, remains within the specification defined in Table 1
3.2 production batch of Iw
quantity of injection water (3.5) produced at one operation at a site where the product has (last) beenphysically or chemically modified to reach compliance with the specification defined in Table 1
Note 1 to entry: Mixing of lW volumes does not constitute a physical or chemical modification so long as thequality of the volumes before mixing complies with the specification given in this document.
3.3 bulk operation
handling of injection water (3.5) in large containers
Note 1 to entry: Large containers can be, for example,road tankers, rail cars, storage tanks and vessels.3.4
packaged shipment
handling of injection water (3.5) in small containers
Note 1 to entry: Small containers can be, for example, drums, cans, bottles and intermediate bulk containers(IBCs].
3.5 injection waterIw
water very low in inorganic,organic or colloidal contaminants,produced, for example, by singledistillation, by deionization, by ultra-filtration or by reverse osmosis manufacture
4 IW analysis parameters
