(Guide)Standard Guide for Sampling Plan and Core Sampling for Prebaked Anodes Used in Aluminum Production
Standard Guide for Sampling Plan and Core Sampling for Prebaked Anodes Used in Aluminum Production
SIGNIFICANCE AND USE
Core sampling is an acceptable way of obtaining a test specimen without destroying the usefulness of an anode block.
4.1.1 Test specimen obtained by this guide can be used by producers and users of carbon anodes for the purpose of conducting the tests in Note 1 to obtain comparative physical properties.
Sampling shall not weaken the anode or increase the likelihood of premature failure.
SCOPE
1.1 This 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.
1.1.1 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. Anodes used in the production of aluminum have specific requirements for sampling and while the statistical basis for sampling given in ISO 5022 applies, further or modified requirements may also apply.
1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.
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 C 559, C 611, C 651, C 747, C 1025, C 1039, and E 1225.
