ISO 11615:2017 establishes definitions and concepts and describes data elements and their structural relationships, which are required for the unique identification and the detailed description of Medicinal Products. Taken together, the standards listed in the Introduction define, characterise and uniquely identify regulated Medicinal Products for human use during their entire life cycle, i.e. from development to authorisation, post-marketing and renewal or withdrawal from the market, where applicable. Furthermore, to support successful information exchange in relation to the unique identification and characterisation of Medicinal Products, the use of other normative IDMP messaging standards is included, which are to be applied in the context of ISO 11615:2017.

 

This document outlines the concepts and principles for information management at a stage of maturity described as “information management according to ISO 19650”. This document provides recommendations for a framework to manage information including recording, versioning, organizing and making it available so that all actors achieve their objectives. This document is applicable to the whole life cycle of any asset, including strategic planning, initial design, engineering, development, documentation and construction, day-to-day operation, maintenance, refurbishment, repair and end-of-life. The framework can be adapted to assets or asset-related projects of any scale and complexity, so as not to hamper the flexibility and versatility that characterize the large range of potential procurement strategies and so as to address the cost of implementing this document.

 

This document specifies requirements for information management, in the form of a business process, within the whole life cycle of assets. This document can be applied to all types of assets, all stages of the asset life cycle, and all types of appointments, and applied by all types and sizes of organization.

 

This GNSS metrology document aims to provide a methodological reference framework for assessing the performance of GNSS based positioning terminals (GBPT) using GNSS (Global Navigation Satellite Systems) technology. In this document, the GBPT is specifically used for various types of vehicles—such as cars, drones, trains, and ships—and not for any timing-related applications. This document is the first part of the ISO 25082 series, specifically developed to structure interactions with clients within the context of test engineering activities. It sets precise conditions for receiving client requests and presenting test results, thereby ensuring clear, effective communication that meets the expectations of both parties. The document defines and characterizes specific operational needs, then translates them into technical requirements, thereby forming a solid foundation for designing relevant and representative test scenarios for various use cases. The approach ensures that the systems tested not only meet operational expectations but also fulfill the desired functionalities for their intended applications. To ensure alignment between requirements and actual performance, the fundamental principle of an assessment is based on measuring the deviations between a reference trajectory, considered ideal but subject to measurement uncertainties, and the trajectories recorded by the Device Under Test (GBPT) to a representative scenario. This comparison process methodically quantifies key parameters such as the accuracy, availability, and reliability of GBPT, taking into account the diverse environmental and operational conditions they may face. In this context, the metrics commonly used to define performance are systematically identified, defined, and classified by their features. These metrics include positioning, velocity, and attitude errors, as well as indicators such as service continuity and availability, performance over time, and data reliability. Each of these metrics can play a critical role in evaluating the overall performance of a GNSS Based Positioning Terminal (GBPT) across varied and sometimes complex scenarios. These same metrics also serve as the basis for defining performance classes to be applied to establish a declaration of compliance. By structuring performance assessments around these indicators, it is possible to ensure that the obtained results meet normative requirements and align with the expectations of clients and certification authorities. Furthermore, this document defines the minimum requirements to consider before selecting the most appropriate testing method from a metrological perspective. The goal is to choose an approach that ensures the validity and reliability of measurements. In addition to their representativeness, the results are repeatable and reproducible from one test to another for the same GBPT and scenario. This methodological rigor is essential for obtaining consistent and comparable data. For the test results are presented in a structured manner to meet the client's expectations, especially in cases where the results shall comply with type certification requirements. Clarity, precision, and rigor in presenting the measured performance are indispensable to ensure that a GNSS Based Positioning Terminal meets the standards and regulations in effect. Finally, this document is primarily aimed at accredited testing laboratories responsible for applying it within the scope of their engineering testing services. It defines the minimum requirements needed to ensure clear and effective communication with fitness-for-purpose-based clients and stakeholders. By rigorously applying these requirements, any organization seeking to plan GNSS tests can optimize the efficiency of its processes while ensuring the production of reliable and accurate results.

 

This document specifies the test method for the experimental characterisation of the out-of-plane permeability of fibrous reinforcements for liquid composite moulding. Requirements for test equipment, test method and data analysis are detailed, to ensure optimal accuracy and reproducibility of the results.

 

This document specifies the method for the characterisation of the compaction response of fibrous reinforcements used in liquid composite moulding. Specimens are compressed at a controlled speed to a predetermined thickness and the relative compressive load is measured. In this method, specimens are tested in both the saturated (“wet”) and unsaturated (“dry”) state. The following steps explain how to prepare the test setup and characterise the compaction response. This method specifies the speed of testing. It should be noted that testing at different speeds can yield different results which may not be comparable.

 

This document specifies the measurement of displacements by means of geodetic instruments carried out for geotechnical monitoring. It refers to position measurements where a signal travels through air/the atmosphere between an instrument and a measuring point (target). General rules of performance monitoring of the ground, of structures interacting with the ground, of geotechnical fills and of geotechnical works are presented in ISO 18674-1:2015. This document is applicable to measurements carried out for monitoring purposes by means of: — tachymeter (manual or robotic ); — level; In informative annexes, this document also refers to principles of some techniques that are commonly used for the monitoring of displacements of topographic surfaces: — satellite Interferometric Synthetic Aperture Radar (InSAR); satellite Interferometric Synthetic Aperture Radar (InSAR); terrestrial radar interferometry ; — laser scanning; — GNSS. NOTE 1 This document fulfils the requirements for the performance monitoring of the ground, of structures interacting with the ground and of geotechnical works by the means of geodetic instruments as part of the geotechnical investigation and testing in accordance with References [1] and [2]. NOTE 2 A key element of any and all monitoring is the ability to reflect the reality of what one intends to measure. There is a wide discrepancy and disagreement between the terms used to call this ability, depending on the field of application and country of origin. ISO/IEC guide 99:2007 defines terms for measurements of one quantity values, whereas in monitoring we generally try to measure change between quantity over time. The terms approaching best our needs in ISO/IEC seems to be “Precision” and “Uncertainty”.
