This Recommendation | International Standard specifies the means by which messages are routed through the MHS, and supplements the procedures defined in 14.3 of ITU-T Rec. X.411 | ISO/IEC 10021-4. Other Recommendations | parts of ISO/IEC 10021 define other aspects of the MHS. ITU-T Rec. F.400/X.400 | ISO/IEC 10021-1 defines the user-oriented services provided by the MHS. ITU-T Rec. X.402 | ISO/…

This Recommendation | Technical Report specifies the means by which the administrator of various aspects of an MHS system may configure information into the directory for MTAs to use to determine the routing of messages. ITU-T Rec. X.412 | ISO/IEC 10021-10 provides a set of directory structures that may be configured in many different ways to support a particular MHS routing strategy. In order to…

Describes a serial, uni-directional, self-clocking interface for the interconnection of digital audio equipment for consumer and professional applications, using linear PCM coded audio samples. It provides the basic structure of the interface. Separate documents define items specific to particular applications.

This Recommendation I International Standard: defines a general framework for context-relative naming, refining and elaborating on the naming concepts defined in Part 2 of the ODP-RM; identifies and characterizes functions necessary to handle names in the context of a federation of different naming systems; and clarifies the relationship between the concepts of name management (i.e. federation…

This Recommendation | International Standard defines a set of lossless (bit-preserving) and nearly lossless (where the error for each reconstructed sample is bounded by a pre-defined value) compression methods for coding continuoustone, gray-scale, or colour digital still images. This Recommendation | International Standard ? specifies a process for converting source image data to compressed…

Provides guidance for assessing the fire hazard of electrotechnical products and for the resulting development of fire hazard testing as related directly to harm to people, animals or property. Products, as defined in this standard, relate to materials, components or complete end-use products. Contains a new informative Annex with an example of the fire hazard assessment technique. The example is…

This part of IEC 60774 is applicable to frequency modulation (FM) audioi recording fully compatible with the VHS system defined in IEC 60774-1. The object of this standard is to define the electrical and mechanical characteristics fo FM audio recording which will provide for the interchangeability of recorded cassettes. The requirements given relate to 525 line-60 field and 625 line-50 field…

1 PURPOSE This standard specifies the physical and dimensional characteristics of prefabricated reinforced concrete and unreinforced concrete pipes and monolithic lateral connections. This standard also specifies control and test methods to verify these requirements. 2 SCOPE This standard applies to round sections of reinforced concrete and unreinforced concrete pipes intended for burial…
