PD CEN/TS 16921:2016 个人身份识别-移动生物识别系统的边界和执法应用概况

This Technical Specification primarily focuses on biometric aspects of portable verification and identification systems for law enforcement and border control authorities. The recommendations given here will balance the needs of security, ease of access and data protection. ISO/IEC has published a series of standards dealing with biometric data coding, interfaces, performance tests as well as compliance tests. It is essential for interoperability that all these standards are applied in European deployments. However, ISO/IEC standards do not consider national or regional characteristics; in particular, they do not consider European Union privacy and data protection regulation as well as accessibility and usability requirements. This Technical Specification extends the ISO standards by emphasizing specific European needs (for example EU data Protection Directive 95/46/EC and European databases access). The Technical Specification systematically discusses issues to be considered when planning, deploying and using portable identity verification systems and gives recommendations for those types of systems that are or will be in use in Europe. Communication, infrastructure scalability, and security aspects other than those related to biometrics are not considered. This document also does not consider hardware and security requirements of biometric equipment and does not recommend general identification procedures.

ASTM E691-16 开展实验室间研究以确定试验方法精度的标准实施规程

4.1 ASTM regulations require precision statements in all test methods in terms of repeatability and reproducibility. This practice may be used in obtaining the needed information as simply as possible. This information may then be used to prepare a precision statement in accordance with Practice E177. Knowledge of the test method precision is useful in commerce and in technical work when comparing test results against standard values (such as specification limits) or between data sources (different laboratories, instruments, etc.). 4.1.1 When a test method is applied to a large number of portions of a material that are as nearly alike as possible, the test results obtained will not all have the same value. A measure of the degree of agreement among these test results describes the precision of the test method for that material. Numerical measures of the variability between such test results provide inverse measures of the precision of the test method. Greater variability implies smaller (that is, poorer) precision and larger imprecision. 4.1.2 Precision is reported as a standard deviation, coefficient of variation (relative standard deviation), variance, or a precision limit (a data range indicating no statistically significant difference between test results). 4.1.3 This practice is designed only to estimate the precision of a test method. However, when accepted reference values are available for the property levels, the test result data obtained according to this practice may be used in estimating the bias of the test method. For a discussion of bias estimation and the relationships between precision, bias, and accuracy, see Practice E177. 4.2 The procedures presented in this practice consist of three basic steps: planning the interlaboratory study, guiding the testing phase of the study, and analyzing the test result data. 4.2.1 The planning phase includes forming the ILS task group, the study design, selection and number of participating laboratories, selection of test materials, and writing the ILS protocol. A well-developed test method, including a ruggedness test to determine control of test method conditions, is essential. Note 1: In this practice, the term test method is used both for the actual measurement process and for the written description of the process, while the term protocol is used for the directions given to the laboratories for conducting the ILS. 4.2.2 The testing phase includes material preparation and distribution, liaison with the participating laboratories, and handling of test result data received from the laboratories. 4.2.3 The data analysis utilizes tabular, graphical, and statistical diagnostic tools for evaluating the consistency of the data so that unusual values may be detected......

EN 13757-5:2015 仪表通信系统.第5部分:无线计量总线中继

This European Standard specifies the protocols to use when performing relaying in wireless meter readout networks. This European Standard is an extension to wireless meter readout specified in EN 13757-4. It supports the routing of modes P and Q, and simple single-hop repeating of modes S, T, C, F and N. The main use of this European Standard is to support simple retransmission as well as routed wireless networks for the readout of meters. NOTE Electricity meters are not covered by this standard, as the standardization of remote readout of electricity meters is a task for IEC/CENELEC.

This practice may be used in obtaining the needed information as simply as possible. This information may then be used to prepare a precision statement in accordance with Practice E177. Knowledge of the test method precision is useful in commerce and in technical work when comparing test results against standard values (such as specification limits) or between data sources (different laboratories, instruments, etc.). 4.1.1 When a test method is applied to a large number of portions of a material that are as nearly alike as possible, the test results obtained will not all have the same value. A measure of the degree of agreement among these test results describes the precision of the test method for that material. Numerical measures of the variability between such test results provide inverse measures of the precision of the test method. Greater variability implies smaller (that is, poorer) precision and larger imprecision. 4.1.2 Repeatability and Reproducibility—These two terms deal with the variability of test results obtained under specified laboratory conditions and represent the two extremes of test method precision. Repeatability concerns the variability between independent test results obtained within a single laboratory in the shortest practical period of time by a single operator with a specific set of test apparatus using test specimens (or test units) taken at random from a single quantity of homogeneous material obtained or prepared for the ILS. Reproducibility deals with the variability between single test results obtained in different laboratories, each of which has applied the test method to test specimens (or test units) taken at random from a single quantity of homogeneous material obtained or prepared for the ILS. 4.1.2.1 Repeatability Conditions—The single-operator, single-set-of-apparatus requirement means that for a particular step in the measurement process the same combination of operator and apparatus is used for every test result and on every material. Thus, one operator may prepare the test specimens, a second measure the dimensions and a third measure the breaking force. “Shortest practical period of time” means that the test results, at least for one material, are obtained in a time not less than in normal testing and not so long as to permit significant changes in test material, equipment or environment. 4.1.2.2 Reproducibility Conditions—The factors that contribute to variability in a single laboratory, such as operator, equipment used, calibration of the equipment, and environment (for example, temperature, humidity, air pollution) will generally have different effects in other laboratories, and the variability among laboratories will be greater . 4.1.3 Precision is reported as a standard deviation, coefficient of variation (relative standard deviation), variance, or a precision limit (a data range indicating no statistically significant difference between test results). 4.1.4 This practice i......
