ČSN EN 1776 (38 6435) This document specifies functional requirements for the design, construction, testing, commissioning/decommissioning, operation, maintenance and, where appropriate, calibration, together with suitable documented provisions for all new gas measuring systems and any major changes of existing systems. This document also specifies accuracy classes of measuring systems and thresholds applicable to these classes. Demonstration of compliance is achieved through the selection, installation and operation of appropriate measurement instruments, together with suitable documented provisions for calculations. Examples of demonstration of compliance are provided for each accuracy class; however, they are not prescriptive solutions. This document is applicable for gases of the 2nd family as classified in EN 437. It is also applicable for treated non-conventional combustible gases complying with EN 437 and for which a detailed technical evaluation of the functional requirements (such as injected biomethane) is performed ensuring there are no other constituents or properties of the gases that can affect the metrological and physical integrity of the measuring systems. This version mentions technical topics to consider when hydrogen and natural gas / hydrogen blends flow through the measuring systems. Blends with a hydrogen content between 20mol% and 98 mol% are not considered by this standard. This document applies to hydrogen with a purity as specified in CEN/TS 17977 for rededicated natural gas systems. This document can also be used as a guideline for measuring systems for other gases e.g. gaseous CO2 for CCUS. This document does not apply to for raw or sour gases. This document does not apply to for gas measurement in CNG filling stations. This document gives guidelines when designing, installing and operating gas meters with additional functionalities (smart gas meters). Communication protocols and interfaces for gas meters and remote reading of gas meters are outside the scope of this document and are covered by the appropriate parts of the EN 13757 series. which provide a number of protocols for meter communications. Supervisory control and data acquisition protocols (SCADA) are also not covered by this document. Unless otherwise specified all pressures used in this document are gauge pressures. For associated pressure regulating systems the requirements of EN 12186 and/or EN 12279 apply. For requirements on design, housing, lay-out, materials for components, construction, ventilation, venting and overall safety of gas measuring systems within the scope of this document, the EN 15001 series, EN 12186, EN 12279 and/or EN 1775 apply additionally, where relevant.

ČSN EN ISO 16757-5 This document describes how product catalogue data for building services products is exchanged by means of ISO 16739-1 (Industry Foundation Classes, IFC) and EN 17549-2 from manufacturers to designers of building services systems. This document specifies how the product catalogue structures and content are set up using the definitions stored in a data dictionary. In scope of this document are: - processes for the provision and exchange of product catalogues; - rules for the geometrical representation of products; - representation of products, product classes, ports, in/outlets, components and accessories by using IFC; - representation of properties in IFC and the use of IFC constraints for the representation of product variants; - representation of parametric geometry and the generation of IFC geometries for selected variants; - calculation of article number. The resulting product catalogue can be used by designers to select the desired products and integrate them into their model of the building services system. The expected audience of this document are software providers for the built environment sector and professionals working in the sector who create product catalogues or use product catalogues by means of software tools. Not in scope of this document is the representation of properties in data dictionaries. The use of data dictionaries is described in ISO 16757-4.

Exclusions: This document is not applicable to the following machines: - machines that were manufactured before the date of publication of this document by CEN; - conveyors that connect palletizers and depalletizers with machines that are not in the scope of this document. Conveyors in the scope of this document also fall in the scope of EN 619:2022, however, this document describes the additional or specific hazards for conveyors fitted into palletizers and depalletizers and so the requirements of this document take precedence over the requirements of EN 619:2022. This document does not consider the following hazards: - the use of palletizers and depalletizers in a potentially explosive atmosphere; - the health, safety or hygiene hazards associated with the products that are contained in the unit load handled by palletizers and depalletizers except for the spillage of hazardous substances caused by the malfunction of a machine.

Plate hooks, which are those, assembled of one or several parallel parts of rolled steel plates, are not covered by this document. The significant hazardous situations and hazardous events that could result in risks to persons during intended use and reasonably foreseeable misuse are identified in Annex N. Clauses 4 to 6 of this document provide requirements and methods to reduce or eliminate the risks of exceeding the limits of strength (yield, ultimate, fatigue, brittle fracture) considering temperature limits of material. The hazards covered by this document are identified in Annex N. This document is applicable to hooks installed in cranes manufactured after the date of approval of this European Standard by CEN and serves as a reference base for product standards of particular crane types.

ČSN EN IEC/IEEE 80005-1 This part of IEC/IEEE 80005 describes high-voltage shore connection (HVSC) systems, onboard the ship and on shore, to supply the ship with electrical power from shore. This document is applicable to the design, installation and testing of HVSC systems and addresses HV shore distribution systems, shore-to-ship connection and interface equipment, transformers/reactors, semiconductor/rotating frequency convertors, ship distribution systems, and control, monitoring, interlocking and power management systems. It does not apply to the electrical power supply during docking periods, for example dry docking and other out of service maintenance and repair. Additional and/or alternative requirements can be imposed by national administrations or the authorities within whose jurisdiction the ship is intended to operate and/or by the owners or authorities responsible for a shore supply or distribution system. It is expected that HVSC systems will have practicable applications for ships requiring 1 MVA or more or ships with HV main supply. Low-voltage shore connection systems are not covered by this document.
