Resumen

ISO 6257:2002 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 in liquid or solid form, the latter having softening points higher than 30 °C (determined according to the method specified in ISO 5940), in bulk, or in a number of containers making up one 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.
