ČSN ETSI EN 300 468 V1.17.1 The present document specifies the Service Information (SI) data which forms a part of Digital Video Broadcasting (DVB) bitstreams, in order that the user can be provided with information to assist in selection of services and/or events within the bitstream, and so that the Integrated Receiver Decoder (IRD) can automatically configure itself for the selected service. SI data for automatic configuration is mostly specified within ISO/IEC 13818-1 [1] as Program Specific Information (PSI). The present document specifies additional data which complements the PSI by providing data to aid automatic tuning of IRDs, and additional information intended for display to the user. The manner of presentation of the information is not specified in the present document, and IRD manufacturers have freedom to choose appropriate presentation methods. It is expected that Electronic Programme Guide (EPG) will be a feature of Digital TeleVision (TV) transmissions. The definition of an EPG is outside the scope of the present document (i.e. the SI specification), but the data contained within the SI specified in the present document may be used as the basis for an EPG. Rules of operation for the implementation of the present document are specified in ETSI TS 101 211 [i.1].

ČSN EN IEC 61158-6-26 ed. 2 The fieldbus Application Layer (FAL) provides user programs with a means to access the fieldbus communication environment. In this respect, the FAL can be viewed as a "window between corresponding application programs". This part of IEC 61158 provides common elements for basic time-critical and non-time-critical messaging communications between application programs in an automation environment and material specific to Type 26 fieldbus. The term "time-critical" is used to represent the presence of a time-window, within which one or more specified actions are required to be completed with some defined level of certainty. Failure to complete specified actions within the time window risks failure of the applications requesting the actions, with attendant risk to equipment, plant and possibly human life.

ČSN EN 17549-2 This document defines a Model View Definition (MVD) of the IFC schema defined in EN ISO 16739-1:2020. The MVD described by this document is designated as CODview2. This document focuses on core and resource classes and relies on external data dictionaries to describe construction specific semantics. NOTE 1 - Core classes are those defined in EN ISO 16739-1:2020, 5. NOTE 2 - Resource classes are those defined in EN ISO 16739-1:2020, 8. This document does not provide any construction object schema as it considers that these are already defined in data dictionaries compliant with EN ISO 12006-3:2022. This document focuses only on the format of the exchanged data and not on the way to process them. CODview2 does not support the geometrical representations of construction objects but allows the exchange of geometrical properties. These properties may be used to define geometrical representations of construction objects.

ČSN EN IEC 60071-2 ed. 3 This part of IEC 60071 constitutes application guidelines and deals with the selection of insulation levels of equipment or installations for three-phase AC systems. Its aim is to give guidance for the determination of the rated withstand voltages for ranges I and II of IEC 60071 1 and to justify the association of these rated values with the standardized highest voltages for equipment. This association is for insulation co-ordination purposes only. The requirements for human safety are not covered by this document. This document covers three-phase AC systems with nominal voltages above 1 kV. The values derived or proposed herein are generally applicable only to such systems. However, the concepts presented are also valid for two-phase or single-phase systems. This document covers phase-to-earth, phase-to-phase and longitudinal insulation. This document is not intended to deal with routine tests. These are to be specified by the relevant product committees. The content of this document strictly follows the flow chart of the insulation co-ordination process presented in Figure 1 of IEC 60071-1:2019. Clauses 5 to 8 correspond to the squares in this flow chart and give detailed information on the concepts governing the insulation co-ordination process which leads to the establishment of the required withstand levels.

ČSN EN 15502-1+A1 This document specifies the common requirements and test methods, as well as the classification, marking and energy labelling of gas-fired central heating boilers that are fitted with atmospheric burners, fan assisted atmospheric burners or fully premixed burners, and are hereafter referred to as "boilers". This document is to be used in conjunction with the specific Parts 2 (Part 2-1, Part 2-2 and following ones). This document applies to boilers of types B and C: NOTE - For further background information on appliance types see EN 1749:2020. a) that use one or more combustible gases of the three gas families at the pressures stated in EN 437:2021; b) where the temperature of the water does not exceed 105 °C during normal operation; c) where the maximum operating pressure in the water circuit does not exceed 6 bar; d) which can give rise to condensation under certain circumstances; e) which are declared in the instructions for installation to be either a "condensing" boiler or a "low temperature boiler" or a "standard boiler" or an "other boiler". If no declaration is given the boiler is to be considered both a "standard boiler" and an "other boiler"; f) which are intended to be installed inside a building or in a partially protected place; g) which are intended to produce also hot water either by the instantaneous or storage principle as a single unit. This document applies to boilers designed for sealed water systems or for open water systems. NOTE - This general standard and the specific standards (see Part 2) provide requirements for boilers with known constructions. For boilers with any alternative constructions, which might not fully be covered by this standard or a specific standard, the risk associated with this alternative construction will need to be assessed. An example of an assessment methodology, based upon risk assessment, is given in Clause 11. This document is not intended to cover appliances intended for connection to gas grids where the quality of the distributed gas is likely to vary to a large extent over the lifetime of the appliance (see Annex AB). This document does not cover all the requirements for : aa) appliances above 1000 kW; ab) appliances designed and constructed to burn gas containing carbon monoxide or other toxic components; ac) appliance having a supplementary heater.
