ASTM D346/D346M-11
(Practice)Standard Practice for Collection and Preparation of Coke Samples for Laboratory Analysis
Standard Practice for Collection and Preparation of Coke Samples for Laboratory Analysis
SIGNIFICANCE AND USE
This practice may be used to provide a representative sample of the coke from which it is collected. Because of the variability of coke and the wide variety of sampling equipment, caution must be exercised in all stages of sampling, from system specifications and equipment procurement to equipment acceptance testing and actually taking the final sample.
This practice also provides an analysis sample of coke from the gross or divided sample. The analysis samples can be used to determine the value of the coke represented, its ability to meet specifications, as well as for other purposes.
SCOPE
1.1 This practice covers procedures for the collection and reduction of samples of coke to be used for physical tests, chemical analyses, and the determination of total moisture.
1.2 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.
1.2.1 Values in SI units [or inch-pound units] shall be obtained my measurement in SI units [or inch-pound units] or by appropriate conversion, using the Rules for Conversion and Rounding given in , of measurements made in other units [or SI units]. Values are state ins SI units when inch-pound units are not used in practice.
1.3 This standard does not purport to address the safety concerns 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.

INTRODUCTION
Coke, especially run of oven coke or foundry coke, or both, is a difficult material to sample. It is
imperative that every sample be collected and handled carefully and conscientiously and in strict
accordance with the standard procedure described herein.
Gross samples of not less than the quantities designated in this practice must be taken, whether the
coke to be sampled consists of a few tons or several hundred tons.
