Full Description

1.1This guide covers sampling for prebaked carbon anodes used in the production of aluminum, and details procedures for taking test samples from anode blocks. It covers equipment and procedures for obtaining samples from anode blocks in a manner that does not destroy the block or prevent its subsequent use as originally intended. However, the user must determine the subsequent use of the sampled anode blocks. Preferred locations for taking samples from single units of anodes are covered in this guide.

1.1.1Information for sampling of shaped refractory products, in general, is given in ISO5022. This standard details the statistical basis for sampling plans for acceptance testing of a consignment or lot. Anodes used in the production of aluminum have specific requirements for sampling and while the statistical basis for sampling given in ISO5022 applies, further or modified requirements may also apply.

1.2The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

1.3This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

Note 1:The following ASTM standards are noted as sources of useful information: Test Methods C559, C611, C651, C747, C1025, C1039, and E1225.
