ČSN EN 17936 This document addresses the measurement of source terms for environmental noise calculation for rail traffic (including light rail, such as trams, metros, etc.). It is applicable to the measurement of in-service trains on operational tracks. It is not applicable to type acceptance testing of rolling-stock or tracks, or to derive source terms for time domain models. The following rail traffic noise source types are in the scope: - rolling noise; - traction and equipment noise; - aerodynamic noise; - impact noise (e.g. rail joints, switch and crossings, wheel flats); - braking noise; - bridge noise; - squeal noise. Noise from rail vehicles at standstill, such as stationary engine idling and auxiliary equipment at yards and stations, is covered by EN ISO 3095:2013 for measurement procedures and operating conditions, and by EN ISO 3740:2019 and EN ISO 3744 for the determination of sound power. It is therefore not in the scope of this document. The calculation of the propagation of sound is part of generally standardized propagation models which are not addressed in this document. Noise from fixed installations (e.g. stations, depots, electricity sub-stations) is not in the scope of this document. Source terms are specific to a vehicle and track type. The scope includes measurement procedures and conditions and sampling requirements.

ČSN P CEN ISO/TS 7127 (36 0070) This technical specification identifies and clarifies lighting properties for digital building design and maintenance. This document provides all the needed properties to design and to describe lighting systems. These properties are intended to be used for mapping between data providers and requesters. The mapping of the identifiers enables the exchange of luminaire and sensing device data within different databases. The unambiguous mapping and description of properties improves the data quality, reduces misinterpretations and the processing time in digital environments. Therefore, the properties listed in this document establish the essential description of lighting systems in BIM systems and databases. The listed properties in this document are used to structure the product data sheet which is complemented with real product information.

ČSN EN ISO 17573-3 This document specifies the syntax and semantics of data objects in the field of electronic fee collection (EFC). The definitions of data types and assignment of semantics are provided in accordance with the abstract syntax notation one (ASN.1) technique, as specified in ISO/IEC 8824-1. This document defines: - ASN.1 (data) types within the field of EFC; - ASN.1 (data) types of a more general use that are used more specifically in standards related to EFC. This document does not seek to define ASN.1 (data) types that are primarily related to other fields that operate in conjunction with EFC, such as cooperative intelligent transport systems (C-ITS), the financial sector, etc.

ČSN EN 12953-6 This document specifies the minimum requirements for safety related equipment for shell boilers (generator and/or assemblies) as specified in EN 12953-1:2012, to ensure the boiler operates within the allowable limits (pressure, temperature, etc.) and if the limits are exceeded the energy supply is automatically interrupted and locked out, irrespective of the degree of intervention. NOTE 1 - For this document, the term "boiler" is applicable for generator and/or assemblies. NOTE 2 - The maximum time of operation without manual (human) intervention can be specified for each boiler system. NOTE 3 - Annex C gives recommendations of operation and testing of the boiler system with a maximum time of operation without manual (human) intervention of 24 h and 72 h.

ČSN EN 1846-2 (38 9301) 1.1 - This document specifies the common requirements for safety and the (minimum) common performance requirements of firefighting and rescue service vehicles as designated in EN 1846-1:2011. NOTE 1 - Categories and mass classes of these vehicles are given in EN 1846-1:2011. NOTE 2 - Vehicle means terrestrial vehicles that can also drive on rails and amphibious vehicles When drafting this document, it has been assumed that the finished standard automotive chassis (or the chassis designed in accordance with the same principles) that is the basis for the firefighting or rescue vehicle offers an acceptable safety level for its basic transport functions within the limits specified by the manufacturer. Therefore, this document does not formulate requirements for this chassis. This document deals with all significant hazards, hazardous situations and events relevant to firefighting and rescue service vehicles, when they are used as intended and under the conditions of misuse which are reasonably foreseeable by the manufacturer. Complementary specific requirements for aerial appliances are the subject of the following European Standards: - EN 1777:2010: Hydraulic platforms (HPs) for firefighting and rescue services, - EN 14043:2014: Turntable ladders with combined movements, - EN 14044:2014: Turntable ladders with sequential movements. NOTE 3 - Additional regulations, not dealt with in this document, can apply in relation with the use of the vehicles on public roads. This document deals with firefighting and rescue vehicles intended for use in a temperature range from -15 °C to +40 °C. NOTE 4 - In the case of utilization outside this temperature range, additional measures might be necessary as agreed between the manufacturer and the user. Such requirements are outside the scope of this document. 1.2 - This document does not deal with the following types of firefighting or rescue vehicles or equipment: - vehicles designed exclusively for carrying personnel; - vehicles with a gross laden mass not exceeding 3 t; - boats; - aircraft; - exclusively railway vehicles; - ambulances (see EN 1789:2020+A1:2023); - provisions for non-firefighting removable equipment driven by PTO; - airport vehicles in the scope of the recommendations of the International Civil Aviation Organization (ICAO). 1.3 - This document deals with the technical requirements to minimize the hazards listed in Annex K which can arise during operational use, routine checking and maintenance of firefighting and rescue service vehicles when carried out in accordance with the specifications given by the manufacturer or his authorized representative. It does not cover the hazards generated by: - non-permanently installed equipment i.e. portable equipment carried on the vehicle; - use in potentially explosive atmospheres; - commissioning and decommissioning; - electromagnetic compatibility. Additional measures not dealt with in this document might be necessary for specific use (e.g. fire in natural environment, flooding, etc.). 1.4 - This document is not applicable to machines that are manufactured before its date of publication as a European Standard.

ČSN EN 17632-2 This document (part 2) provides extended standard semantic modelling patterns for (at least) the following domain-specific asset aspects: - support for distinction between two subtypes of physical objects: spatial regions and real ("tangible") objects; the latter being discrete or continuous ("bulk matter"); - support for the materialization of physical objects, adding generic chemistry aspects directly relevant for the built environment dealing with materials like concrete, steel, wood and asphalt; - support for the interaction between objects including connections, interfaces and ports. Interactions being defined as activities where material, information, energy or forces are transferred; - support for the definition of unstructured, human-interpretable, requirements, coming from appointing party needs, laws and regulations or sector recommendations; - support for implicit groups having no explicit members (to model situations like "all main girders of some steel bridge"); - support for the explicit modelling of measurements reusing the existing W3C SOSA ontology (as a lightweight but self-contained SSN core ontology); - support for spatial geometry (location/shape) reusing OGC GeoSPARQL (GML/WKT) and the WGS84_pos ontology (GPS).
