Over deze norm
Specifies methods for sampling and preparing samples prior to testing of binder pitch used in the manufacture of electrodes for the electrolytic production of aluminium. These methods are applicable to grades of pitch or sold form, the latter having softening points higher than 30°C (determined according o the method specified in ISO 5940), in bulk, or in a number of containers making up ne batch at sites of manufacture, storage, or delivery. Sampling methods and sampling plans for large consignments, or lots, of pitch in liquid form during the loading and unloading of ships are included.
