Standard Guide for Sampling Plan and Core Sampling of Carbon Cathode Blocks Used in Aluminum Production


1.1 This sampling guide was developed for carbon cathode blocks used in the production of aluminum, and details procedures for taking test samples from single cathode blocks. It covers equipment and procedures for obtaining samples from cathode 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 cathode blocks. Preferred locations for taking samples from single units of cathodes are covered in this guide.

1.1.1 Information for sampling of shaped refractory products, in general, is given in ISO 5022. This standard details the statistical basis for sampling plans for acceptance testing of a consignment or lot. Cathode blocks used in the production of aluminum have specific requirements of sampling, and while the staistical basis or sampling given in ISO 5022 applies, further or modified requirements may, also, apply.

1.2 SI units are the standard in this guide.

1.3 This 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.

Significance and Use

Core sampling is an acceptable way of obtaining a test specimen without destroying the usefulness of a cathode block.

4.1.1 Test specimens obtained by this guide can be used by producers and users of cathode blocks for the purpose of conducting the tests in Note 1 to obtain comparative physical properties.

Sampling shall not weaken the cathode or increase the likelihood of premature failure. Extreme care shall be exercised when taking vertically drilled samples.
