Describes a method to check, in terms of functional parameters, that the constancy of the quality of images produced by intra-oral dental X-ray equipment is maintained after installation, calibration and adjustment have been carried out. This standard defines: - the functional parameters, which describe the performance of X-ray equipment for intra-oral dental radiographic examination; - methods…

Applies to those components of X-ray equipment which a) generate, influence the propagation of, and detect X-radiation, and b) process, present and store diagnostic X-ray images in radiological installations with diagnostic X-ray systems for indirect radioscopy and indirect radiography which use X-ray image intensifiers in conjunction with analogue and/or digital storage systems: - closed-circuit…

Applies to those components of X-ray equipment which - generate, influence the propagation of and detect X-radiation; - process, record and present radiographic information in radiological installations with mammographic X-ray equipment using intensifying screens with radiological films. This standard defines - the essential parameters which describe or affect the performance of the above…

Applies to data communication in Open Trains. Defines interfaces so as to achieve plug-in compatibility between equipment located in different vehicles and between equipment located within the same vehicle. Allows for interoperability of individual vehicles within Open Trains in international traffic. Guidelines for conformance testing are included.

Defines generic requirements, which govern SCSI-3 implementation standards, and implementation requirements that apply to all SCSI-3 devices. Implementation requirements specify behavior in terms of measurable or observable parameters pertaining to an implementation. Generic requirements are transformed to implementation requirements by an implementation standard. This standard contains a…

Defines type, production and optional test on thyristor valves used in thyristor controlled reactots (TCR), Thyristor switched reactor (TSR) and thyristor switched capacitors (TSC) forming part of static VAR compensators (SVC) for power system applications. the requirements of the standard apply both to single valve units (one phase) and to multiple valve units (several phases). Clauses 4 to 7…
