GB/T 26297.2-2010Sampling of carbonaceous materials used for aluminium production -- Part 2: Sidewall blocks (English PDF)

Foreword

GB/T 26297 "sampling method of carbon material with aluminum" is divided into six parts.

--- Part 1. Bottom charcoal;

--- Part 2. side carbon block;

--- Part 3. prebaked anode;

--- Part 4. cathode paste;

--- Part 5. coal tar pitch;

--- Part 6. calcined petroleum coke.

This is Part 2.

This section drafted in accordance with GB/T 1.1-2009 given rules.

This section uses redrafted Law Amendment uses ISO 8007-3:2003 "carbonaceous materials used in aluminum Sampling plans and sampling from a single block Part 3. the side of charcoal. " The partial modification of the use of ISO 8007-3:2003, it will be its preface, introduction, normative references and definitions Delete, and modify them according to a technical domestic situation. At the same time, to make it easier sampling operation, a number of additions and modifications Provisions, which identifies a single vertical line in which they are involved in terms of margin. To facilitate comparison, listed in Appendix A this part of the clauses and the corresponding ISO 8007-3:2003 section of the table as well as the technical differences. Such modifications and provisions are.

--- Clearly defines the direction perpendicular to the sample to Omo;

--- Advice from a random sample of each batch of charcoal in charcoal and charcoal in the amount of sample taken to meet the meet the inspection requirements.

The non-ferrous metal part by the National Standardization Technical Committee (SAC/TC243) centralized.
