This International Standard specifies test methods for determining the physical properties of synchronous belts used in driving engine parts, such as camshafts, fuel injection pumps, balancing shafts. These test methods are intended to provide a means of characterizing synchronous belt properties for belts which are evaluated and qualified by dynamic laboratory and field testing. NOTE The…

This International Standard specifies a method for the determination of lethal as well as sublethal effects of contaminated sediments on the ostracod crustacean Heterocypris incongruens after 6 d exposure. The method is applicable not only to fresh water sediments, but also by extension to solid wastes and soils after addition of (uncontaminated) water. The method can also be applied to…

This International Standard provides procedures for electron microprobe elemental-mapping analysis using wavelength-dispersive spectrometry. The choice between mapping with the electron beam moving digitally across the specimen (electron beam mapping) and mapping with stage movement only (large-area mapping) is assessed. It describes five types of data processing: the raw X‑ray intensity data…

ISO 27729:2012 specifies the International Standard name identifier (ISNI) for the identification of public identities of parties, i.e. the identities used publicly by parties involved throughout the media content industries in the creation, production, management and content distribution chains. The ISNI system uniquely identifies public identities across multiple fields of creative activity and…

ISO/TS 14033:2012 supports the application of standards and reports on environmental management. It provides guidelines on how to acquire quantitative environmental information and data and implement methodology. It gives guidelines to organizations on general principles, policy, strategy and activities necessary to obtain quantitative environmental information for internal and/or external…

This International Standard provides space system manufacturing organizations with the minimum interface related items and generic format for creating the interface control document (ICD) which subsystems or units suppliers prepare for spacecraft systems (SC) integrators. In this International Standard, ICD is not defined to contain descriptions regarding various properties of subsystems or units…

This International Standard specifies test methods and performance requirements for ensuring proper wheel or rim assembly on road vehicles by means of hexagonal nuts with a flat seating captive washer used with 18 mm, 20 mm and 22 mm studs. It is applicable to commercial vehicles as defined in ISO 3833 and to those nuts as specified in ISO 7575. It is not applicable to fasteners for less common…

1 Scope This Recommendation | International Standard defines ACSE services for ASO-association control in an open systems interconnection environment. ACSE supports two modes of communication service: connection-mode and connectionless-mode. The ACSE connection-mode service is provided by the use of the connection-mode ACSE protocol (see ITU-T Rec. X.227 bis | ISO/IEC 15954). The ACSE…

Scope This Technical Report specifies an extension to the programming language C, specified by the International Standard ISO/IEC 9899:1999. The extension provides support for decimal floating-point arithmetic that is intended to be consistent with the specification in IEEE 754-2008. Any conflict between the requirements described here and that specification is unintentional. This Technical…
