ČSN EN ISO 20888 This document defines the terms used to describe the distinctive characteristics of an individual's mouth by dentists and forensic dental experts. These terms are organized by concepts based on a forensic approach to the characteristics of a mouth, with many concepts specific to the identification domain that are not defined elsewhere in ISO dentistry vocabularies (e.g. "present tooth"). The hierarchical structure of this document is designed to describe attributes of a tooth, the mouth and a prosthesis/orthosis with increasing levels of discriminative characteristics (e.g. material characteristics, restored tooth surface) and the possibility to connect any level of description of an attribute with the most comprehensive concept. This document is intended to be used for data exchange between antemortem and postmortem files and remove ambiguity on the terms used to describe an individual's mouth. This document is intended to be used in conjunction with ISO 1942 and ISO 3950.

ČSN EN ISO 12967-2 This document specifies the fundamental characteristics of the information model implemented by a specific architectural layer (i.e. the service architecture) of the information system to provide a comprehensive and integrated storage of the common enterprise data and to support the fundamental business processes of the healthcare organization, as defined in ISO 12967-1.

ČSN EN 12493 This document specifies minimum requirements for materials, design, construction and workmanship procedures, and tests for welded LPG road tanker pressure vessels and their welded attachments manufactured from carbon, carbon/manganese and micro alloy steels. There is no upper size limit as this is determined by the gross vehicle weight limitation. This document does not cover pressure vessels for pressure vessel containers. NOTE 1 - In the context of this document, the term "road tanker" is understood to mean "fixed tanks" and "demountable tanks" as defined in ADR. NOTE 2 - The equipment for the pressure vessels and the inspection and testing after assembly is covered by EN 12252 and EN 14334, respectively. NOTE 3 - The design type of the road tanker is subject to approval by the competent authority, as required by ADR. NOTE 4 - This document is intended for LPG only; however, for other liquefied gases see EN 14025.

ČSN EN ISO 15156-2 This document gives requirements and recommendations for the selection and qualification of carbon and low-alloy steels for service in equipment used in oil and natural gas production and natural gas treatment plants in H2S-containing environments, whose failure can pose a risk to the health and safety of the public and personnel or to the environment. It can be applied to help to avoid costly corrosion damage to the equipment itself. It supplements, but does not replace, the materials requirements of the appropriate design codes, standards or regulations. This document addresses the resistance of these steels to damage that can be caused by sulfide stress cracking (SSC) and the related phenomena of stress-oriented hydrogen-induced cracking (SOHIC) and soft-zone cracking (SZC). This document also addresses the resistance of these steels to hydrogen-induced cracking (HIC) and its possible development into stepwise cracking (SWC). This document is concerned only with cracking. Loss of material by general (mass loss) or localized corrosion is not addressed. Table 1 provides a non-exhaustive list of equipment to which this document is applicable, including exclusions. This document applies to the qualification and selection of materials for equipment designed and constructed using load controlled design methods. For design utilizing strain-based design methods, see ISO 15156-1:2020, Clause 5. Annex A lists SSC-resistant carbon and low alloy steels, and A.2.4 includes requirements for the use of cast irons. This document is not necessarily suitable for application to equipment used in refining or downstream processes and equipment.

ČSN ETSI EN 301 925 V1.6.1 The present document specifies the minimum requirements for shipborne radio transmitters and receivers for fixed installations operating in the VHF frequency bands between 156 MHz and 174 MHz used by the maritime mobile service, using both 25 kHz and 12,5 kHz channels and capable of Radiotelephony and Digital Selective Calling communications within the Global Maritime Distress and Safety System. The present document incorporates the requirements of the relevant resolutions of the International Maritime Organization (IMO) and is primarily intended to specify equipment suitable for fitting to ships subject to the SOLAS Convention [i.2] and complying with the Council Directive 2014/90/EU [i.3] of 23 July 2014 on marine equipment (the European Marine Equipment Directive). The present document does not address the testing of ancillary equipment on a stand-alone basis, i.e. separately from the radio equipment with which it is to be used.

ČSN EN IEC 60603-7 ed. 3 Tato norma pokrývá 8pólové nestíněné volné a pevné konektory, odkazuje na rozměry, mechanické a elektrické charakteristiky, charakteristiky prostředí a zkoušky pro konektory řady IEC 60603-7-x. Tyto konektory jsou vzájemně zasunutelné (v souladu s IEC 61076-1 úroveň 2) a schopné vzájemné činnosti (interoperativní) s dalšími konektory souboru IEC 60603-7.

ČSN EN IEC 62566-2 This part of IEC 62566 provides requirements for achieving highly reliable HDL-Programmed Devices (HPDs), for use in I&C systems of nuclear power plants performing functions of safety category B or C as defined by IEC 61226. The programming of HPDs relies on Hardware Description Languages (HDL) and related software tools. They are typically based on blank Field Programmable Gate Arrays (FPGAs) or similar micro-electronic technologies such as Programmable Logic Devices (PLD), Complex Programmable Logic Devices (CPLDs), etc. General purpose integrated circuits such as microprocessors are not HPDs. Annex B.8 provides descriptions of a number of different types of integrated circuits.

ČSN EN IEC 60268-22 This part of IEC 60268 applies to transducers converting an electrical input signal into a mechanical or acoustical output signal. However, if the electrical input terminals and the surface of the radiator are accessible, this document can also apply to passive and active sound systems such as loudspeakers, headphones, TV-sets, multi-media devices, personal portable audio devices, automotive sound systems and professional equipment. This document describes only electrical and mechanical measurements that help assess the transfer behaviour of the device under test (DUT). This includes operating the DUT in both the small- and largesignal domains. The influence of the target application's acoustical boundary conditions (e.g. car interior) can also be considered in the physical evaluation of the sound system. Perception and cognitive evaluations of the reproduced sound and the impact of perceived sound quality are outside the scope of this document.

ČSN ISO 1928 Tento dokument specifikuje metodu pro stanovení spalného tepla tuhých paliv při konstantním objemu a referenční teplotě 25 °C ve spalovací nádobě kalorimetru, kalibrované spálením certifikované kyseliny benzoové. Výsledek, získaný touto metodou, je spalné teplo analytického vzorku při konstantním objemu s celkovou vodou ze zplodin hoření v kapalném stavu. V praxi se palivo spaluje za konstantního (atmosférického) tlaku a voda nekondenzuje, ale odchází jako pára ve spalinách. Za těchto podmínek je účinným teplem výhřevnost paliva při konstantním tlaku. Lze také používat výhřevnost při konstantním objemu; vzorce pro výpočet obou hodnot jsou uvedeny.
