This document specifies a method for the determination of interlaminar shear strength at ambient temperature by the compression of a double-notched test piece and a method for the determination of interlaminar shear strength and modulus at ambient temperature by the Iosipescu test. This document applies to all ceramic matrix composites with a continuous fibre reinforcement, having unidirectional (1D), bidirectional (2D) and multidirectional (xD, with x > 2) fibre architecture, where a major part of reinforcements is a stack of plies.
This document is applicable to material development, material comparison, quality assurance, characterization, reliability and design data generation. The simpler compression test method of a double-notched test piece is applicable only when the shear strength has to be measured.

This document specifies a method for the determination of cyclosiloxanes in chemicals used in the tanning industry

This document specifies procedures suitable for the analysis of data which, when converted into logarithms
of the values, have either a normal or a skewed distribution. It is intended for use with test methods and
referring standards for glass-reinforced thermosetting plastics (GRP) pipes or fittings for the analysis of
properties as a function of time. However, it can also be used for the analysis of other data.
Two methods are specified, which are used depending on the nature of the data. Extrapolation using these
techniques typically extends a trend from data gathered over a period of approximately 10 000 h to a
prediction of the property at 50 years, which is the typical maximum extrapolation time.
This document only addresses the analysis of data. The test procedures for collecting the data, the number of samples required and the time period over which data are collected are covered by the referring standards and/ or test methods. Clause 6 discusses how the data analysis methods are applied to product testing and design.

This document specifies a procedure for a chamber test with different options of chamber sizes to measure the formaldehyde concentrations in air from wood products under defined test conditions of temperature, relative humidity, loading and air exchange rate.
Results obtained from this small-scale chamber test method can be used for quality control (factory production control – ‘FPC’) based on correlation established by reference chamber test methods according to ISO, EN or ASTM standards. The establishment of a correlation is described in Annex D.

This document sets out a review of the current methods and practices (including tools, assets, and conditions of acceptability) for
conformity assessment in respect to, among others, products, services, processes, management systems, organizations, or persons,
as relevant for the development and use of AI systems. It includes an industry horizontal (vertical agnostic) perspective as well as an
industry vertical perspective.
This document focuses only on the process of assessment and gap analysis of conformity. It defines the objects of conformity
related to AI systems and all other related aspects of the process of conformity assessment. The document also reviews to what
extent AI poses specific challenges with respect to assessment of, for example, software engineering, data quality and engineering
processes.
This document takes into account requirements and orientations from policy frameworks such as the EU AI strategy and those from
CEN and CENELEC member countries.
This document is intended for technologists, standards bodies, regulators and interested parties.

This document defines terms for the specification of important characteristics of alpine skis, cross-country skis (XC-skis) and snowboards.

This document provides a possible instantiation of the registry metamodel specified in ISO/IEC 11179-3, ISO/IEC 11179-31, ISO/IEC 11179-32 using the SQL database language as specified in ISO/IEC 9075-2.

The management of electronic transport regulations (METR) provides a means for METR users to obtain trustworthy, authoritative, machine-interpretable, publicly available and transport-related information for the use of the road network, in order to provide safer and more efficient, sustainable, comfortable, and equitable transport services. The scope of METR includes both rules that are relatively static (e.g. static speed limits) as well as those that are dynamic (e.g. variable speed limits, signalized intersections). Where appropriate, METR incorporates existing documents (e.g. ISO/TS 19091 for signalized intersections). This document defines terms specific to the ISO 24315 series on the management of electronic transport regulations.

This document is applicable to private sector, public sector or community organizations.

This document defines a CCSDS Recommended Practice (and ISO standard) on which to base the operations of the organization(s) which assess the trustworthiness of digital repositories using the latest version of CCSDS 652.0/ISO 16363 (reference REF R_652x0m2AuditandCertificationofTrustwor \h[1] 08D0C9EA79F9BACE118C8200AA004BA90B02000000080000002900000052005F00360035003200780030006D0032004100750064006900740061006E006400430065007200740069006600690063006100740069006F006E006F0066005400720075007300740077006F0072000000 ) and provide the appropriate certification. This document specifies requirements for bodies providing audit and certification of digital repositories, based on the metrics contained within ISO/IEC 17021-1 (reference REF R_ISOIEC170212011ConformityAssessmentReq \h \* MERGEFORMAT [4] 08D0C9EA79F9BACE118C8200AA004BA90B02000000080000002900000052005F00490053004F0049004500430031003700300032003100320030003100310043006F006E0066006F0072006D006900740079004100730073006500730073006D0065006E0074005200650071000000 ) and reference REF R_652x0m2AuditandCertificationofTrustwor \h[1] 08D0C9EA79F9BACE118C8200AA004BA90B02000000080000002900000052005F00360035003200780030006D0032004100750064006900740061006E006400430065007200740069006600690063006100740069006F006E006F0066005400720075007300740077006F0072000000 . It is primarily intended to support the accreditation of bodies providing such certification. ISO/IEC 17021-1 provides the bulk of the requirements on bodies offering audit and certification for general types of management systems. However, for each specific type of system, specific additional requirements will be needed, for example, to specify the standard against which the audit is to be made and the qualifications which auditors require. This document provides the (small number of) specific additions required for bodies providing audit and certification of candidate trustworthy digital repositories. Trustworthy here means that they can be trusted to maintain, over the long-term, the understandability and usability of digitally encoded information placed into their safekeeping. In order improve readability the section numbers are kept consistent with those of ISO/IEC 17021-1. Some subsections are applicable as they stand, and these are simply enumerated; otherwise additions to subsections are explicitly given. In the former case the sections may consist of just a few sentences. As a result this document must be read in conjunction with ISO/IEC 17021-1. The requirements contained in this CCSDS Recommended Practice need to be demonstrated in terms of competence and reliability by any organization or body providing certification of digital repositories.

This document establishes the acceptance criteria according to EN 50388-1:2022, 10.2 for compatibility between traction units and power supply for known phenomena and known technologies. That is in relation to: - co-ordination between controlled elements and also between these elements and resonances in the electrical infrastructure in order to achieve network system stability; - co-ordination of harmonic behaviour with respect to excitation of electrical resonances. The following electric traction systems are within the scope: - railways; - guided mass transport systems that are integrated with railways; - material transport systems that are integrated with railways. Public three-phase networks are out of the scope, but networks which are dedicated to railways are included. This document is applied in accordance with the requirements in EN 50388-1:2022, Clause 10. It does not apply retrospectively to rolling stock or railway power supply elements already in service. It is the aim of this Part 2 to support acceptance of new elements (rolling stock or infrastructure) by specifying precise requirements and methods for demonstration of compliance. This document acts as “code of practice” quoted in EN 50388-1:2022, 10.2. However, it is still admissible to use the process as defined in EN 50388-1:2022, 10.3 instead. This version of the standard only applies to AC systems. Later versions might include similar effects in DC networks in addition, see Annex D. The main phenomena identified and treated in this document are: - electrical resonance stability; - low frequency stability; - overvoltages caused by harmonics. The interaction with signalling (including track circuits) is not dealt with in this document.

This document defines a process assessment model for quantitative processes, conforming to the requirements of ISO/IEC 33004, for use in performing a process assessment in accordance with the requirements of ISO/IEC 33002.
