GB/T 15000 It aims to establish guidelines that are generally applicable to the preparation, valuation, packaging, storage, distribution and application of standard sample producers. It consists of 8 parts. ---Part 1.General provisions for standard samples stated in technical standards. The purpose is to provide for the statement of standards in the formulation of technical standards General requirements for samples, the relationship between standard samples and technical standards, technical criteria for selecting standard samples, etc. ---Part 2.Commonly used terms and definitions. The purpose is to specify terms and definitions related to standard samples, especially those used for standard samples. terminology in product product instructions, certificates and corresponding development reports. ---Part 3.Standard sample determination and uniformity and stability evaluation. The purpose is to provide more specific guidance on technical issues Guide, and provide a basic model for the homogeneity, stability evaluation and setting process of standard samples. ---Part 4.Contents of certificates, labels and accompanying documents. The purpose is to establish standards applicable to the preparation of standard sample certificates, labels and attachments. Relevant requirements that need to be followed when bringing file content. ---Part 5.Internal development of quality control samples. The purpose is to standardize and guide the development and use of quality control samples. ---Part 6.General rules for standard sample packaging. The purpose is to establish basic rules applicable to standard sample packaging, storage and transportation. ---Part 7.General requirements for the capabilities of standard sample producers. The purpose is to stipulate relevant organizational management and operational requirements to ensure Standard sample producers can produce standard samples that meet the requirements. ---Part 8.Use of standard samples. The purpose is to provide guidance for the correct use of standard samples. This document gives usage suggestions in the form of examples, which in a sense also reflects the complexity of RM. The level of detail helps To anyone responsible for quality management in the laboratory (e.g. drafting of protocols, work instructions, standard operating procedures and similar documents (authors, reviewers, managers and reviewers, etc.) on the understanding of this document and the use of standard samples. Standard sample work guide Part 8.Use of standard samples1 Scope1.1 This document describes the standardized use of reference samples (RM), especially certified reference samples (CRM), during the measurement process. It mainly includes Assessment of precision and correctness of measurement methods, quality control, assigning values to other materials, calibration and establishment of agreed scales. This document also covers different Various applications of type RM key features. 1.2 The characteristic values of CRM are metrologically traceable and can be traced to international scales or other measurement standards. Although the RM characteristic value outside of CRM Although such traceability is usually not established, such RMs can still be used for part of the evaluation of the measurement procedure, including the evaluation of different levels of precision. 1.3 The main applications of RM include precision control (Chapter 8), bias assessment (Chapter 9), calibration (Chapter 10), calibration RM preparation (Chapter 9) Chapter 11) and maintaining the agreed upon scale (Chapter 12). Note. Not all types of RM can be used in all the above applications. 1.4 ISO Guide341)[1] and ISO Guide35[2] also involve the preparation of calibration standard samples. This document is only suitable for use in laboratory equipment such as The preparation and assignment of small quantities of RM for preparation purposes is not applicable to the production of large-scale RM for distribution purposes, which is included in in ISO Guide34 and ISO Guide35. 1) ISO Guide34.2000 was replaced by ISO 17034.2016, and the original guide document was abolished. ISO 17034.2016 has been equivalently converted into GB/T 15000.7-2021. 1.5 This document does not address the development of working standards for industries such as natural gas analysis, clinical chemistry and pharmaceuticals. Such activities are included in in ISO Guide34 and ISO Guide35.2 Normative reference documentsThe contents of the following documents constitute essential provisions of this document through normative references in the text.
