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 section drafted in accordance with GB/T 1.1-2009 given rules.
This section uses redrafted Law Amendment uses ISO 14422.1999 "carbonaceous materials used in aluminum cold ramming paste sampling method." This section
Modify using ISO 14422.1999, it will be its catalog, foreword, normative references as well as terms and definitions to delete, and scope
Ramming paste extended from the cold cathode paste for all. According to the domestic situation and the cathode paste was carried out in the specific application of technical repair the cell
change. At the same time, to make it easier sampling operation, additions and modifications to some provisions that a single vertical line identifies the article to which they are involved

Carbonaceous materials used in aluminum sampling method
Part 4. cathode paste
1 Scope
This section GB/T 26297 specifies the cathode paste sampling methods and conditions.
This section applies to the cathode paste sample.
2 General
2.1 Types of sampling devices, sample preparation and processing should not change the performance of the sample to be measured, and the supply and demand sides to this
Agreement.
2.2 In the case of mobile sampling, also should not change the characteristics of the sample to be measured, such as shipping and delivery when handling, packaging (see 4.4.5).
2.3 In the sampling, reduction of sub-sample or preparation and storage process, to prevent any change in other factors to be measured sample performance.
2.4 If necessary, and agreed by both sides, to be divided into several independent inspection lot consignment separately sampled (for example, the
When the consignment by different production batches and they constitute a clear separation between production batches, the consignment or different visual grounds, can be a single
Only when the number of divisions composition).
2.5 A complete sampling process, all parts of the required samples distributed throughout the consignment, and shall be a fixed amount or fixed
Sampling a given time interval, additionally, the entire delivery of quality or divided into a plurality of time intervals, samples were taken at intervals each, in the initial sample is first
1 randomly selected time interval to complete.
3 equipment and tools
3.1 should ensure that containers containing samples, sampling devices and anything that might be taken with a sample contact auxiliary equipment clean and dry.
3.2 Bifurcation four. four blade rigid metallic material non-permeable material or between them at right angles to each other even in the center
Together. Four each blade fork height ratio should be placed under the flat column-like height of the stack height (see 4.4.2), its length should
Than flattened sample stack a large radius.
3.3 Sampling spoon. Take the product according to the size of the largest particles in the sample to determine the spoon in width, at least six times the maximum particle size, and can
The minimum sample volume increment 1 as claimed in the following table was filled.
Table 1 Minimum sample volume increment
Maximum particle size/mm minimum increment sampling volume/g
20 2000 ± 200
10 500 ± 50
3 200 ± 20
1 50 ± 5
3.4 Sampling gun. Figures 1 and 2, the minimum inner diameter D should be taken six times the maximum product particle size, and can be filled in Table 1 below
The minimum increment sample size required. Sampler length L should be about 10% longer than the depth of the product is taken.
