This International Standard defines how user oriented performance of computer-based software systems (CBSS) may be measured and rated. A CBSS is a data processing system as it is seen by its users, e.g. by users at various terminals, or as it is seen by operational users and business users at the data processing center. A CBSS includes hardware and all its software (system software and…

This International Standard specifies the test apparatus, test gas mixtures, sampling procedures and analytical techniques used to determine the performance of refrigerant recovery and/or recycling equipment (hereinafter, "equipment"). This International Standard also specifies the refrigerants to be used for the evaluation of equipment, i.e. halogenated hydrocarbon refrigerants and…

This part of ISO/IEC 16500 describes the management architecture and protocol for managing the DAVIC System. The DAVIC system management architecture is the TMN-based (Telecommunication Management Network) architecture defined in ITU-T Recommendation M.3010. This management architecture allows for automatic administration, configuration, monitoring, billing, and maintenance of the Service…

ISO/IEC 8632 provides a file format suitable for the storage and retrieval of picture description information. The file format consists of an ordered set of elements that may be used to describe pictures in a way that is compatible between systems of different architectures, compatible with devices of differing capabilities and design, and meaningful to application constituencies. This picture…

This International Standard specifies requirements for epoxy powders for use in preparing fusion-bonded epoxycoated steel reinforcing bar, wire and welded fabric. This International Standard also includes requirements for sealing material used to repair damaged areas and cut ends on reinforcing steel. This International Standard defines a flexible (type A) coating and a nonflexible (type B)…

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 connectionless-mode…

This Recommendation | International Standard specifies: a) procedures for the transfer of information among application-service-objects (ASOs); and b) the abstract and concrete syntax for the representation of the A-UNIT-DATA ACSE APDU. The A-UNIT-DATA procedure is defined in terms of: a) The interactions between peer ACSE protocol machines by the use of a supporting service; and b) the…

This International Standard describes an open-loop test method for determining vehicle reactions during a straightline braking manoeuvre on a surface having a split coefficient of friction. It applies to passenger cars as defined in ISO 3833. The method is valid for all braking efforts up to full ABS operation for vehicles so equipped, or just up to the locking limit of the wheels on the high-…

This Recommendation | International Standard provides the specification of management information within an Open System related to those operations of the OSI Physical Layer specified by the specifications in this Recommendation | International Standard. Specifics on how Physical Layer management is accomplished is beyond the scope of this Recommendation | International Standard. Physical Layer…

This part of ISO/IEC 16500 describes an Abstract System Reference Model (ASRM) at the highest level first and then creates a specific instance of this abstract model to define the DAVIC System Reference Model (DSRM). The ASRM and DSRM are not intended to indicate preferred implementations of the DAVIC System; but are to be used as a tool to guide the definition of DAVIC specifications.…
