GSO ISO/IEC Guide 98-4:2021 测量不确定度 第4部分：测量不确定度在合格评定中的作用

ISO/IEC Guide 98-4:2012 provides guidance and procedures for assessing the conformity of an item (entity, object or system) with specified requirements. The item might be, for example, a gauge block, a grocery scale or a blood sample. The procedures can be applied where the following conditions exist: the item is distinguished by a single scalar quantity (a measurable property) defined to a level of detail sufficient to be reasonably represented by an essentially unique true value; an interval of permissible values of the property is specified by one or two tolerance limits; the property can be measured and the measurement result expressed in a manner consistent with the principles of the GUM, so that knowledge of the value of the property can be reasonably described by (a) a probability density function, (b) a distribution function, (c) numerical approximations to such functions, or (d) a best estimate, together with a coverage interval and an associated coverage probability. The procedures developed in this document can be used to realize an interval, called an acceptance interval, of permissible measured values of the property of interest. Acceptance limits can be chosen so as to balance the risks associated with accepting non-conforming items (consumer's risk) or rejecting conforming items (producer's risk). Two types of conformity assessment problems are addressed. The first is the setting of acceptance limits that will assure that a desired conformance probability for a single measured item is achieved. The second is the setting of acceptance limits to assure an acceptable level of confidence on average as a number of (nominally identical) items are measured. Guidance is given for their solution. This document contains examples to illustrate the guidance provided. The concepts presented can be extended to more general conformity assessment problems based on measurements of a set of scalar measurands. The audience of this document includes quality managers, members of standards development organizations, accreditation authorities and the staffs of testing and measuring laboratories, inspection bodies, certification bodies, regulatory agencies, academics and researchers.

Uncertainty of measurement — Part 4: Role of measurement uncertainty in conformity assessment

GSO OIML R139-1:2021 车辆压缩气体燃料测量系统 第1部分：计量技术要求

In general, the measuring systems that are covered by this Recommendation are intended for the refueling of motor vehicles, small boats, and aircraft with compressed natural gas, hydrogen, biogas, gas blends or other compressed gaseous fuels. They may also be applicable to other vehicles, for instance trains. Measuring systems for liquid petroleum gas are not included in the scope of this Recommendation. These are within the scope of OIML R 117, which covers fluids in a liquid state. In principle, this Recommendation applies to all measuring systems fitted with a meter as defined in 3.2.2 (continuous measurement), whatever the measuring principle may be of the meters or their application. This Recommendation is not intended to prevent the development of new technologies. According to the state of the art, this Recommendation is intended for measuring systems providing mass indications.

Compressed gaseous fuel measuring systems for vehicles. Part 1: Metrological and technical requirements

GSO OIML D11:2021 测量仪器的通用要求 环境条件

2.1 This Standard specifies general metrological requirements applicable to measuring instruments concerning environmental influences and describes tests for verifying the compliance of an instrument with these requirements. 2.2 This Standard shall be taken into account by OIML Technical Committees, Subcommittees and Project Groups when establishing performance requirements and tests for a specific category of measuring instruments concerning their sensitivity to influence quantities. Note 1: This Standard does not cover requirements for measuring instruments which are not related to external influence quantities and which are to be covered by the specific OIML Recommendation. For example: requirements for zero-setting devices, totalizers, etc. Note 2: This Standard does not address aspects such as safety or emission of electromagnetic phenomena from measuring instruments. The requirements for these aspects are beyond the OIML scope and should be taken into account in accordance with the applicable international, regional or national regulations. Note 3: This Standard does not address aspects concerning transportation of measuring instruments while not in operation. Requirements concerning transportation-related durability, handling and maintenance aspects are beyond the OIML scope. 7 GSO OIML D 11:2018 GULF STANDARD Note 4: This Standard does not address aspects of influences by remote protocols such as software routines.

GSO IEC 62828-1:2021 测试工业和过程测量变送器的参考条件和程序 第1部分：所有类型变送器的通用程序

IEC 62828-1:2017 establishes a general framework for defining reference conditions and test procedures applicable to all types of industrial and process measurement transmitters (PMTs) used in measuring and control systems for industrial process and machinery. These reference test conditions are divided into “standard reference conditions”, which apply when determining the accuracy of measurement, and “ambient and process reference conditions”, which are used to assess the influence of external quantities on the measurement. The IEC 62828 series cancels and replaces the IEC 60770 series and proposes revisions for the IEC 61298 series.

GSO OIML G19:2021 测量不确定度在法定计量合格评定决策中的作用

important objective of this Guide is to demonstrate how measurement uncertainty can be taken into account, at least implicitly, for measuring instruments and systems that have been verified. This is important since uncertainty assessment is critical so that measurement results (values and uncertainties) that are obtained when subsequently using the verified instrument/system can have metrological traceability.

The role of measurement uncertainty in conformity assessment decisions in legal metrology

GSO OIML D32:2021 ISO/IEC 17065在法定计量认证机构评估中的应用指南

OIML guidance to clause 1 (G.1-1 to G.1-3) G.1-1 “Certification bodies” are national issuing authorities and OIML Issuing Authorities under the OIML-CS. G.1-2 “Third-party conformity assessment” is national type approval and issuing OIML Certificates. G.1-3 The word “product” shall be understood as meaning the measuring instrument type (including families of measuring instruments, modules, or families of modules) subject to national type approval or issuing OIML Certificates. Processes and services are not relevant to national type approval and issuing OIML Certificates.

GSO ISO/TS 17503:2021 不确定性评估的统计方法 使用二因素交叉设计评估不确定性的指南

ISO/TS 17503:2015 describes the estimation of uncertainties on the mean value in experiments conducted as crossed designs, and the use of variances extracted from such experiments and applied to the results of other measurements (for example, single observations). ISO/TS 17503:2015 covers balanced two-factor designs with any number of levels. The basic designs covered include the two-way design without replication and the two-way design with replication, with one or both factors considered as random. Calculations of variance components from ANOVA tables and their use in uncertainty estimation are given. In addition, brief guidance is given on the use of restricted maximum likelihood estimates from software, and on the treatment of experiments with small numbers of missing data points. Methods for review of the data for outliers and approximate normality are provided. The use of data obtained from the treatment of relative observations (for example, apparent recovery in analytical chemistry) is included.
