ISO 14617-1:2005 serves as an introduction to all the other parts of ISO 14617. In particular, it gives information on the creation and use of registration numbers for identifying graphical symbols used in diagrams, rules for the presentation and application of these symbols, and examples of their use and application. It includes three indexes: an alphabetic index and an index of registration…

This International Standard provides methods for _ determining the composition of a calibration gas mixture by comparison with appropriate reference gas mixtures, _ calculating the uncertainty of the composition of a calibration gas mixture in relation to the known uncertainty of the composition of the reference gas mixtures with which it was compared, _ checking the composition attributed to a…

ISO 17744:2004 describes procedures for determining the specific volume of plastics as a function of temperature and pressure in both the molten and solid states. The standard specifies the use of a piston-equipped apparatus in which the test sample, held in a measurement cell, is pressurized by means of the piston. Measurements under conditions of constant pressure or constant temperature can be…

ISO 3170:2004 specifies the manual methods to be used for obtaining samples of liquid or semi-liquid hydrocarbons, tank residues and deposits from fixed tanks, railcars, road vehicles, ships and barges, drums and cans, or from liquids being pumped in pipelines. ISO 3170:2004 applies to the sampling of petroleum products, crude oils and intermediate products, which are stored in tanks at or near…

This International Standard specifies methods for the estimation of measurement uncertainty of chemical and physicochemical methods in single laboratories based on validation data and analytical quality control results obtained within the field of water analysis. NOTE 1 The principles of the estimation of uncertainty specified in this International Standard are consistent with the principles…

This document defines the requirements of capabilities of build and deployment tools to support and automate build, package, and deployment work. This document is intended for use in evaluating and selecting build and deployment tools according to the procedures defined in ISO/IEC 20741. By using these two standards together, objective and rational results can be derived for the evaluation and…

This document specifies: — the general principles governing the biological evaluation of medical devices within a risk management process; — the general categorization of medical devices based on the nature and duration of their contact with the body; — the evaluation of existing relevant data from all sources; — the identification of gaps in the available data…

ISO 4582:2017 specifies methods to determine changes in colour and other appearance properties, and variations in mechanical or other properties, of plastics that have been exposed to glass-filtered solar radiation, to natural weathering or to simulated solar radiation from a laboratory source. The procedure used to analyse data depends on whether the test used to characterize the materials being…

ISO 20289:2018 provides a chemical method for technicians working with Total Reflection X-ray Fluorescence (TXRF) instrumentation to perform measurements of water samples, according to good practices, with a defined degree of accuracy and precision. Target users are identified among laboratories performing routine analysis of large numbers of samples, which also comply with ISO/IEC 17025. ISO…

ISO/IEC 18026:2009 specifies the Spatial Reference Model (SRM) defining relevant aspects of spatial positioning and related information processing. The SRM allows precise and unambiguous specification of geometric properties such as position (location), direction, and distance. The SRM addresses the needs of a broad community of users, who have a range of accuracy and performance requirements in…
