CEN ISO/TS 21911-2:2022 固体回收燃料自热的测定第2部分：篮式加热试验（ISO/TS 21911-2:2022）

This document gives guidance on basket heating tests for characterization of self-heating properties of solid recovered fuels (SRFs). This document includes: a) a compilation of basket heating test methods; b) guidance on the applicability and use of basket heating tests for SRF; c) information on the application of basket heating test data for calculations of critical conditions in storage. Data on spontaneous heat generation determined using this document is only associated with the specific quality and age of the sample material. The information derived using this document is intended for use in quality control and in hazard and risk assessments related to the procedures given in ISO 21912.

EN ISO 21646:2022 固体回收燃料.样品制备

This document specifies methods for sample preparation to ensure representativeness of the samples throughout the preparation procedures to produce general analysis samples. Suitable test portions can be taken from the laboratory or general analysis samples and used for analysis according to the specific requirements defined in the corresponding analytical procedures. This document specifies the correct sample preparation sequence to be applied to: a) the composite sample, in order to produce a laboratory sample (taking into account large pieces of solid recovered fuel); b) each sub-sampling step throughout the testing programme; c) the laboratory sample, in order to obtain suitable test portions; d) ensure the representativeness of the test portions that have been taken according to the sample preparation plan, prior to physical analysis, chemical analysis or both (e.g. extractions, digestion, analytical determinations). The methods specified in this document can be used for sample preparation, for example, when the samples are to be tested for bulk density, biomass content determination, mechanical durability, particle size distribution, moisture content, ash content, ash melting behaviour, calorific value, chemical composition, impurities and self-heating properties. The methods are not intended to be applied to the very large samples required for the testing of bridging properties.

ASTM D5709-22 石油焦筛分分析的标准试验方法

1.1 This test method details a procedure for performing particle size distribution analysis by dry sieve testing on green petroleum coke with a topsize of no more than 75 mm and calcined petroleum coke with a topsize of no more than 25 mm. Size fractions go down to and include 4.75 mm for green petroleum coke and 75 µm for calcined petroleum coke. NOTE 1—To convert units, see Table 1 on nominal dimensions in Specification E11. For example, 75 mm is approximately equivalent to a nominal sieve opening of 3 in. and 25 mm to a nominal sieve opening of 1 in. Likewise, 4.75 mm can be converted to approximately 0.187 in. and 75 microns to 0.0029 in. 1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.2.1 The sieve size is reported as U.S.A. standard test series in any units listed in Table 1 on nominal dimensions of Specification E11, or their commercial size equivalents. 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 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.

ASTM D2944-22 园艺用加工泥炭材料取样的标准实施规程

1.1 This practice covers the procedure for obtaining a representative sample of processed peat material from compressed bales or bulk loose material sources. This procedure is applicable for sampling peat materials for horticultural purposes and produces a sample that is representative of peat materials that may be heterogeneous in nature. Producing a representative sample of a material is central to the validity of the results for any testing or analytical procedure which can be used to verify the grade of peat. 1.2 Units—The values stated in SI units are to be regarded as the standard. The values given in parentheses are provided for information only and are not considered standard. 1.3 All observed and calculated values shall confirm to the guidelines for significant digits and rounding established in Practice D6026. 1.3.1 The procedures used to specify how data are collected/ recorded or calculated in this standard are regarded as the industry standard. In addition, they are representative of the significant digits that generally should be retained. The procedures used do not consider material variation, purpose for obtaining the data, special purpose studies, or any considerations for the user’s objectives; and it is common practice to increase or reduce significant digits of reported data to be commensurate with these considerations. It is beyond the scope of this standard to consider significant digits used in analysis methods for engineering design. 1.4 This practice offers a set of instructions for performing one or more specific operations. This document cannot replace education or experience and should be used in conjunction with professional judgment. Not all aspects of this practice may be applicable in all circumstances. This ASTM standard is not intended to represent or replace the standard of care by which the adequacy of a given professional service must be judged, nor should this document be applied without consideration of a project’s many unique aspects. The word ”Standard” in the title of this document means only that the document has been approved though the ASTM consensus process. 1.5 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.6 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.

1.1 This test method gives equations to enable analytical data from the application of RDF analysis procedures to be expressed on various different bases in common use. Such bases are: as-received; dry; dry, ash-free; and others. 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 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.
