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 specifies a thermal conductimetric method after fusion under inert gas for the determination of nitrogen in steel and iron. The method is applicable to nitrogen contents between 0,002 % (m/m) and 0,6 % (m/m).

This International Standard specifies a potentiometric titration method for the determination of chromium content in steel and iron. The method is applicable to chromium contents between 1 % (m/m) and 35 % (m/m). Vanadium contents in steel and iron should be less than 1 % (m/m) for chromium contents higher than 10 % (m/m) and less than 0,2 % (m/m) for chromium contents less than 10 % (m/m).

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 part of ISO 13584 specifies an application programming interface that enables an application program to generate geometric models that are independent of the target user system. The interface allows portability of programs that describe parametric shape representations of parts families held in an ISO 13584 parts library. The following are within the scope of this International Standard: —…

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 International Standard specifies the essential dimensional requirements for size "S" fuel nozzles used in diesel engines. These requirements allow the assembly and interchangeability of the nozzles in the corresponding nozzle holders. This International Standard is applicable to size "S" nozzles, which comprise hole type, long-stem nozzles (types A1 and A2) and pintle…

This International Standard applies to implementation and application of test charts for colour copying machines. This International Standard serves for testing of reproduction properties of colour copying machines, in order to help to recognize the possibilities and limits of various machines and for their comparison. To use this International Standard, make copies of at least two test charts (…

This International Standard specifies the physical and magnetic characteristics of a 12,7 mm wide, 128-track magnetic tape cartridge, to enable physical interchangeability of such cartridges between drives. It also specifies the quality of the recorded signals, a format - called Digital Linear Tape 3 Extended (DLT 3-XT) - and a recording method, thereby allowing data interchange between drives.…
