1.1 本规程规定了在实验室中操作和评估质量和管理系统的要求，该实验室使用煤炭和焦炭D05委员会管辖下的ASTM标准提供煤炭、焦炭和来自煤炭或焦炭的灰分的样品收集、样品制备或测试服务。 注1: “实验室”一词在本规范中用于指代提供煤炭采样或测试服务或两者兼有的组织。然而，人们认识到，该词可能不适用于不进行实际实验室样品测试的组织。 1.2 国际标准ANSI/ISO/IEC 17025应为规定实验室管理、技术能力和评估要求的管理文件。 注2: 实验室服务的认证机构或用户也可以施加ANSI/ISO/IEC 17025中未明确规定的技术或非技术要求，前提是这些要求不会使ANSI/ISO/IEC 17025的要求无效。 1.3 本规程仅用于评估实验室明确要求的能力。 1.4 除非另有说明，否则所有百分比均为质量分数百分比。 1.5 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的用户有责任在使用前制定适当的安全和健康实践，并确定监管限制的适用性。 ====意义和用途====== 3.1 国际标准ANSI/ISO/IEC 17025提倡使用记录在案的责任和质量控制程序，以确保实验室及其客户能够在其采样、样品制备和测试活动的日常执行中产生技术有效的数据和结果。 3.2 实验室应使用ANSI/ISO/IEC 17025制定其质量体系。ANSI/ISO/IEC 17025第4条规定了声音管理的要求。ANSI/ISO/IEC 17025第5条规定了实验室承担的测试或校准类型或两者的技术能力要求。 3.3 除了符合ANSI/ISO/IEC 17025的要求外，本标准实施规程的附录还包含了对合格煤炭和焦炭取样或测试设施的评估和运行或两者都重要的信息。 本附录中的信息在ANSI/ISO/IEC 17025或适用ASTM方法中未涵盖的地方提供。 3.4 认可测试和校准实验室能力的实验室客户、监管机构和认证机构可以使用本标准惯例作为其评估的基础。 3.5 本实践的主要意义在于确定实验室要生成可追溯到国际单位制的测量值，必须: 3.5.1 清楚了解客户要求的工作。 3.5.2 符合国际公认的ANSI/ISO/IEC 17025标准的质量体系要求。 3.5.3 使用已证明可追溯到国际单位制测量单位的测试方法。 3.5.4 能够证明实验室在进行测量时处于统计控制状态。

1.1 This practice specifies requirements to operate and evaluate the quality and management systems in a laboratory that provides services with respect to sample collection, sample preparation, or testing of coal, coke, and ash derived from coal or coke using ASTM standards that are under the jurisdiction of Committee D05 on Coal and Coke. Note 1: The word “laboratory” is used throughout this practice when referring to an organization that provides services in coal sampling or testing, or both. It is recognized, however, that the word may not be appropriate to an organization that does not perform actual laboratory sample testing. 1.2 International standard ANSI/ISO/IEC 17025 shall be the governing document specifying requirements for management, technical competence and evaluation of a laboratory. Note 2: An accrediting body or user of laboratory services can also impose technical or non-technical requirements not specifically addressed in ANSI/ISO/IEC 17025 provided they do not invalidate the requirements of ANSI/ISO/IEC 17025. 1.3 This practice is used to evaluate only those capabilities specifically claimed by a laboratory. 1.4 All percentages are percent mass fractions unless otherwise noted. 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 and health practices and determine the applicability of regulatory limitations prior to use. ====== Significance And Use ====== 3.1 International standard ANSI/ISO/IEC 17025 promotes the use of documented accountability and quality control procedures to assure a laboratory and its clients that the laboratory can produce technically valid data and results in the routine performance of its sampling, sample preparation and testing activities. 3.2 A laboratory shall use ANSI/ISO/IEC 17025 to develop its quality system. Clause 4 of ANSI/ISO/IEC 17025 specifies the requirements for sound management. Clause 5 of ANSI/ISO/IEC 17025 specifies the requirements for technical competence for the type of tests or calibrations, or both the laboratory undertakes. 3.3 In addition to complying with the requirements of ANSI/ISO/IEC 17025, the Annex of this standard practice contains information that shall be considered important for the evaluation and operation of a competent Coal and Coke sampling or testing facility, or both. The information in this Annex is presented where it is not otherwise covered in ANSI/ISO/IEC 17025 or the applicable ASTM methods. 3.4 Laboratory clients, regulatory authorities, and accreditation bodies that recognize the competence of testing and calibration laboratories can use this standard practice as the basis for their evaluation. 3.5 The primary significance of this practice is to establish that for a laboratory to generate measurements traceable to SI units, it must: 3.5.1 Have a clear understanding of the work requested by the client. 3.5.2 Meet the quality system requirements of the internationally accepted ANSI/ISO/IEC 17025 standard. 3.5.3 Use test methods which have been shown to be traceable to SI units of measurement. 3.5.4 Be able to demonstrate that the laboratory is in statistical control at the time the measurements are made.
