This European Standard specifies the boundary conditions and the prove methods for the determination of the thermal output of hot water floor heating systems as a function of the temperature difference between the heating medium and the room temperature. This standard shall be applied to commercial trade and practical engineering if proved and certifiable values of the thermal output shall be used. This European Standard applies to heating and cooling systems embedded into the enclosure surfaces of the room to be heated or to be cooled. This Part of this European Standard applies to hot water floor heating systems. Applying of Part 5 of this European Standard requires the prior use of this Part of this European Standard. Part 5 of this European Standard deals with the conversion of the thermal output of floor heating systems determined in Part 2 into the thermal output of heating surfaces embedded in walls and ceilings as well as into the thermal output of cooling surfaces embedded in floors, walls and ceilings. The thermal output is proved by a calculation method (Clause 6) and by a test method (Clause 9). The calculation method is applicable to systems corresponding to the definitions in EN 1264 1 (type A, type B, type C, type D). For systems not corresponding to these definitions, the test method shall be used. The calculation method and the test method are consistent with each other and provide correlating and adequate prove results. The prove results, expressed depending on further parameters, are the standard specific thermal output and the associated standard temperature difference between the heating medium and the room temperature as well as fields of characteristic curves showing the relationship between the specific thermal output and the temperature difference between the heating medium and the room.

8. Scope This European Standard applies to heating and cooling systems embedded into the enclosure surfaces of the room to be heated or to be cooled. This document deals with the use in practical engineering of the results coming from part 2 and 5 and is applicable to floor-, ceiling- and wall heating systems, as well floor-, ceiling- and wall cooling systems. For heating systems, physiological limitations are taken into account when specifying the surface temperatures. In the case of floor heating systems the limitations are realised by a design based on the characteristic curves and limit curves determined in accordance with part 2 of this Standard. For cooling systems, only a limitation with respect to the dew point is taken into account. In predominating practice, this means that physiological limitations are included as well.

This European Standard applies to water based heating and cooling systems embedded into the enclosure surfaces of the room to be heated or to be cooled. Part 5 of this standard deals with the recalculation of values determined in Part 2 of this European Standard for the system in question, using it for floor heating applications. The recalculation method described in this part of the standard enables the conversion of the calculation and test results of Part 2 into results for other surface orientations in the room, i. e. for ceiling and wall heating, as well as for the application as cooling surfaces, i. e. for floor, ceiling and wall cooling. It has to be emphasised that the test results of Part 2 of this European Standard are the basis of all calculation. Therefore the use of this prove method is necessary whether or not the system in question is used for heating or cooling application. This European Standard shall be applied to commercial trade and practical engineering if proved and certifiable values of the thermal output shall be used.

This Recommendation | International Standard specifies the syntax and semantics of video usability information (VUI)

parameters and supplemental enhancement information (SEI) messages. The VUI parameters and SEI messages defined

in this standard may be conveyed within coded video bitstreams in a manner specified in a video coding specification or

may be conveyed by other means as determined by the specifications for systems that make use of such coded video

bitstreams. This document is particularly intended for use with coded video bitstreams as specified by Rec. ITU-T H.VVC |

ISO/IEC 23090-3, although it is drafted in a manner intended to be sufficiently generic that it may also be used with other

types of coded video bitstreams.

This document is written in a manner such that it is intended to be referenced by other technical specifications. Such other

technical specifications are to be written in a manner to specify certain necessary elements to enable the use of the VUI

parameters and SEI messages.

VUI parameters and SEI messages can assist in processes related to decoding, display or other purposes. However, unless

otherwise specified in a referencing specification, the interpretation and use of the VUI parameters and SEI messages

specified in this document is not a required functionality of a video decoder or receiving video system. Although semantics

are specified for the VUI parameters and SEI messages, decoders and receiving video systems may simply ignore the

content of the and VUI parameters and SEI messages or may use them in some manner not specified in this document.

This Recommendation | International Standard specifies a video coding technology known as Versatile Video Coding, comprising a video coding technology with a compression capability that is substantially beyond that of the prior generations of such standards and with sufficient versatility for effective use in a broad range of applications.

Only the syntax format, semantics, and associated decoding process requirements are specified, while other matters such as pre-processing, the encoding process, system signalling and multiplexing, data loss recovery, post-processing, and video display are considered to be outside the scope of this Recommendation | International Standard. Any encoding process that produces bitstream data that conforms to the specified bitstream syntax format requirements of this Recommendation | International Standard is considered to be in conformance with the requirements of this Recommendation | International Standard. Additionally, the internal processing steps performed within a decoder are also considered to be outside the scope of this Recommendation | International Standard; only the externally observable output behaviour is required to conform to the specifications of this Recommendation | International Standard. The decoding process is specified such that all decoders that conform to a specified combination of capabilities known as the profile, tier, and level will produce numerically identical cropped decoded output pictures when invoking the decoding process associated with that profile for a bitstream conforming to that profile, tier and level. Any decoding process that produces identical cropped decoded output pictures to those produced by the process described herein (with the correct output order or output timing, as specified) is considered to be in conformance with the requirements of this Recommendation | International Standard.

This Recommendation | International Standard is designed to be generic in the sense that it serves a wide range of applications, bit rates, resolutions, qualities and services. Applications should cover, among other things, digital storage media, television broadcasting and real-time communications. In the course of creating this Recommendation | International Standard, various requirements from typical applications have been considered, necessary algorithmic elements have been developed, and these have been integrated into a single syntax. Hence, this Recommendation | International Standard will facilitate video data interchange among different applications.

Considering the practicality of implementing the full syntax of this Recommendation | International Standard, however, a limited number of subsets of the syntax are also stipulated by means of "profiles", "tiers" and "levels". These and other related terms are formally defined in Clause 3.

A "profile" is a subset of the entire bitstream syntax that is specified in this Recommendation | International Standard. Within the bounds imposed by the syntax of a given profile, it is still possible to require a very large variation in the performance of encoders and decoders depending upon the values taken by syntax elements in the bitstream such as the specified size of the decoded pictures. In many applications, it is currently neither practical nor economical to implement a decoder capable of dealing with all hypothetical uses of the syntax within a particular profile.

In order to deal with this problem, "tiers" and "levels" are specified within each profile. A level of a tier is a specified set of constraints imposed on values of the syntax elements in the bitstream. These constraints may be simple limits on values. Alternatively they may take the form of constraints on arithmetic combinations of values (e.g., picture width multiplied by picture height multiplied by number of pictures decoded per second). A level specified for a lower tier is more constrained than a level specified for a higher tier.

Coded video content conforming to this Recommendation | International Standard uses a common syntax. In order to achieve a subset of the complete syntax, flags, parameters and other syntax elements are included in the bitstream that signal the presence or absence of syntactic elements that occur later in the bitstream.

Rec. ITU-T H.SEI | ISO/IEC 23002-7 specifies the syntax and semantics of the video usability information (VUI) parameters and supplemental enhancement information (SEI) messages that do not affect the conformance specifications in Annex C. These VUI parameters and SEI messages may be used together with this Recommendation | International Standard.

This is the first version of this Recommendation | International Standard.

This European Standard provides an accepted "terminology" for switch and crossing work. With the assistance of diagrams, the various components are given definitions, and these specific names are regarded as obligatory.

The definitions cover the constituent parts and design geometry of switch and crossing work, and include the movement of switches. Additional terminology of a more specific nature will be defined in the relevant part of the series.

The present definitions set out the terms most generally used for the geometrical form and the construction of switches and crossings, omitting those of too special a nature.
