The goal of the non-repudiation service is to generate, collect, maintain, make available and validate evidence concerning a claimed event or action in order to resolve disputes about the occurrence or non-occurrence of the event or action. Provides descriptions of generic structures that can be used for non-repudiation services, and of some specific communication-related mechanisms which can be used to provide non-repudiation of origin (NRO) and non-repudiation of delivery (NRD). Other non-repudiation services can be built using the generic structures described in this standard in order to meet the requirements defined by the security policy. Relies on the existence of a trusted third party (TTP) to prevent fraudulent repudiation or accusation.
This standard describes the Link Services requirements. The Physical Interface requirements are described in Fibre Channel-Physical Interfaces - 2 (FC-PI-2). The Framing and Signaling requirements are described in Fibre Channel-Physical Framing and Signaling - 3 (FC-FS-3). This standard is recommended for new implementations but does not obsolete the existing Fibre Channel standards.
Specifies two methodologies for the measurement of specific print quality attributes of two-dimensional bar code symbols printed within the requirements of Digital Postage Marks. One of these methodologies is applicable to multi-row bar code symbologies and the other to two-dimensional matrix symbologies. Defines methods for grading print quality attributes and deriving an overall assessment of symbol quality. Gives information on possible causes of deviation from optimum grades so as to assist users and postal operators in taking appropriate corrective action.

Defines a protocol for the transport of commands and data over High Performance Serial Bus. The transport protocol, Serial Bus Protocol 2 or SBP-2, requires implementations to conform to the requirements of this standard as well as to ISO/IEC 13213:1994 and permits the exchange of commands, data and status between initiators and targets connected to Serial Bus.

Defines a file format that integrates 3D graphics and multimedia. Conceptually, each VRML file is a 3D time-based space that contains graphic and aural objects that can be dynamically modified through a variety of mechanisms. This part of ISO/IEC 14772 defines a primary set of objects and mechanisms that encourage composition, encapsulation, and extension.
Establishes the structure of a geographic information classification system, together with the mechanism for defining and registering the classifiers for such a system. It specifies the use of discrete coverages to represent the result of applying the classification system to a particular area and defines the technical structure of a register of classifiers in accordance with ISO 19135.

ISO/IEC 1001:2012 specifies the file structure and the labelling of magnetic tapes for the interchange of information between users of information processing systems. It specifies - volume and file structure, - basic characteristics of the blocks containing the records constituting the file, - recorded labels for identifying files, file sections and volumes of magnetic tapes, and - four nested levels of interchange.

This standard defines the concepts of conformance testing for biometric data interchange formats and defines a general conformance testing framework. It specifies common (modality-neutral) elements of the testing methodology, such as test methods and procedures, implementation conformance claim, and test results reporting. It also provides the assertion language definition and sets forth other testing and reporting requirements, and outlines other aspects of the conformance testing methodology that are generally applicable and not modality-specific. As part of the conformance testing methodology, different types and levels of conformance testing are described, as well as their applicability. The conformance testing methodology specified in ISO/IEC 29109-1:2009 is concerned only with data interchange format records and systems that produce or use these records.
