ASTM D6354-12(2017)

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.
Designation: D6354 − 12 D6354 − 12 (Reapproved 2017)
Standard Guide for
Sampling Plan and Core Sampling of Carbon Cathode
Blocks Used in Aluminum Production
This standard is issued under the fixed designation D6354; the number immediately following the designation indicates the year of
original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A
superscript epsilon (´) indicates an editorial change since the last revision or reapproval.
1. Scope*Scope
1.1 This guide covers sampling of carbon cathode blocks used in the production of aluminum, and details procedures for taking
samples from single cathode blocks. It covers equipment and procedures for obtaining samples from cathode blocks in a manner
that does not destroy the cathode 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 cathode blocks 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 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 standard. No other units of measurement are included in this standard.
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 safety, health, and healthenvironmental 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
C1225.
1.4 This international standard was developed in accordance with internationally recognized principles on standardization
established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued
by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

3. Terminology
3.1 Definitions of Terms Specific to This Standard:
3.1.1 cathode block, n—one manufactured unit used as a negative carbon electrode.
3.1.2 sample, n—a portion of carbon obtained from a cathode block.
3.1.3 test specimen, n—a representative piece of a sample.
4. Significance and Use
4.1 Core sampling is an acceptable way of obtaining a test specimen without destroying the usefulness of a cathode block.
