Solid recovered fuels — Guidance for the specification of solid recovered fuels (SRF) for selected u...
This document addresses the provision of background references that are helpful in defining a more detailed specification for SRF according to its specific end use for energy conversion (EfW plants) and to support the SRF market. The aim is to enable all the interested stakeholders – producers, end users, legislators, local authority bodies and standardization bodies – to guarantee that the SRF…
Space systems — General test methods for spacecraft, subsystems and units
This document provides the baseline standard on the subject of testing at the system, subsystem and unit levels for applicable unmanned spacecraft programmes. It also provides the requirements for documentation associated with testing activities.
This document contains provisions for qualification and acceptance testing, or proto-flight testing (PFT). It assumes that hardware development is…
Water quality — Determination of microcystins — Method using liquid chromatography and tandem mass s...
This document specifies a method for the quantification of twelve microcystin variants (microcystin-LR, -LA, -YR, -RR, -LY, -WR, -HtyR, -HilR, -LW, -LF, [Dha7]-microcystin-LR, and [Dha7]-microcystin-RR) in drinking water and freshwater samples between 0,05 µg/l to 1,6 µg/l. The method can be used to determine further microcystins, provided that analytical conditions for chromatography and mass…
Information technology — Open systems interconnection — Part 7: The Directory: Selected object class...
1 Scope
This Recommendation | International Standard defines a number of object classes and name forms which may be found useful across a range of applications of the Directory. The definition of an object class involves listing a number of attribute types which are relevant to objects of that class. The definition of a name form involves naming the object class to which it applies and listing…
Information technology — Open systems interconnection — Part 8: The Directory: Public-key and attrib...
1 Scope
This Recommendation | International Standard addresses some of the security requirements in the areas of authentication and other security services through the provision of a set of frameworks upon which full services can be based. Specifically, this Recommendation | International Standard defines frameworks for:
–public-key certificates; and
–attribute certificates.
The public-key…
Information technology — Open systems interconnection — Part 9: The Directory: Replication
1 Scope
This Recommendation | International Standard specifies a shadow service which Directory system agents (DSAs) may use to replicate Directory information. The service allows Directory information to be replicated among DSAs to improve service to Directory users. The shadowed information is updated, using the defined protocol, thereby improving the service provided to users of the Directory.

1 Scope
The scope of this Recommendation | International Standard is threefold.
This Recommendation | International Standard provides guidance on how to prepare new and old protocols for cryptographic algorithm migration, and defines auxiliary cryptographic algorithms to be used for migration purposes.
This Recommendation | International Standard specifies a general wrapper protocol that…
Information technology — Metamodel framework for interoperability (MFI) — Part 3: Metamodel for onto...
1 Scope
This document specifies the metamodel that provides a facility to register administrative and evolution information related to ontologies.
The metamodel is intended to promote interoperability among application systems, by providing administrative and evolution information related to ontologies, accompanied with standardized ontology repositories that register ontologies themselves in…
Information technology for learning, education and training — Catalogue model for virtual, augmented...
1 Scope
This document describes how to search for virtual reality (VR), augmented reality (AR) and mixed reality (MR) content through a curriculum catalogue based on curriculum and achievement standards information. The curriculum catalogue metadata is defined in order to search for educational VR and MR content information.
