ČSN EN 16843 Tento dokument se zabývá kolejnicovými styky pro trvalou montáž u širokopatních kolejnic o hmotnosti 46 kg/m a vyšší. Předmětem dokumentu je stanovit požadavky na izolované a neizolované styky kolejnic se spojkami, na namáhané kolejnice (průběžná svařovaná kolejnice, CWR) a na nenamáhané kolejnice (bezstyková kolej), definovat mechanické a elektrické požadavky pro schválení typu a pro přejímku izolovaných kolejnicových styků, které jsou vyráběny ve výrobním závodě (dílenský kolejnicový styk) i montovány na staveništi (kolejnicový styk in situ). Dokument specifikuje minimální požadavky. Speciální aplikace, jako například tramvajové systémy, mohou v určitých odstavcích vyžadovat odlišné požadavky, které jsou dohodnuty mezi zákazníkem a dodavatelem. Dokument se vztahuje na kolejnicové styky tvořené dvojicí kolejnic s kolmými nebo šikmými konci kolejnice. Předmětem tohoto dokumentu nejsou v žádném případě takové typy styků kolejnic, které se používají pro dočasnou montáž v koleji, které se užívají například při stavbě kolejí nebo k zajištění lomů kolejnic a svarů před konečnou opravou. Předmětem dokumentu rovněž nejsou dilatační zařízení (uvedená v EN 13232-8) a speciální styky v konstrukcích výhybek.

ČSN EN 18001 This document provides product category rules (PCR) for Type III environmental declarations for curtain walling as defined in EN 13830:2015+A1:2020, excluding openable infills. Openable infills are addressed in EN 17213:2020. This document complements the core rules for the product category of construction products as defined in EN 15804:2012+A2:2019. This document complements EN 15804:2012+A2:2019 and does not replace it. The core PCR: - defines the parameters to be declared and the way in which they are collated and reported; - describes which stages of a product's life cycle are considered in the EPD and which processes are to be included in the life cycle stages; - defines rules for the development of scenarios; - includes the rules for calculating the life cycle inventory and the life cycle impact assessment underlying the EPD, including the specification of the data quality to be applied; - includes the rules for reporting the predetermined, environmental and health information that is not covered by life cycle assessment (LCA) for the product, construction process(es) and construction service(s), as relevant; - defines the conditions under which construction products can be compared based on the information provided by EPD. For the EPD of construction services the same rules and requirements apply as for the EPD of construction products.

ČSN EN ISO 20236 This document specifies a method to determine the total organic carbon (TOC), dissolved organic carbon (DOC), total bound nitrogen (TNb) and dissolved bound nitrogen (DNb) in the form of free ammonia, ammonium, nitrite, nitrate and organic compounds capable of conversion to nitrogen oxides. Cyanide, cyanate and particles of elemental carbon (soot), when present in the sample, can be determined together with the organic carbon. Dissolved nitrogen gas (N2) is not determined. NOTE - Generally, the method can be applied for the determination of total carbon (TC) and total inorganic carbon (TIC) - see Annex A. The method is applicable to water samples (e.g. drinking water, raw water, ground water, surface water, sea water, waste water, leachates). This document is applicable to determination of TOC and DOC >=1 mg/l and TNb and DNb >=1 mg/l. The upper working range is restricted by instrument-dependent conditions (e.g. injection volume). Higher concentrations can be determined after appropriate dilution of the sample. The determination of concentrations

ČSN P CEN ISO/TS 7552-3 This document specifies requirements and gives recommendations on the handling, storage, CTC enrichment, preparation for CTC staining, and documentation of venous whole blood specimens intended for staining of CTCs during the pre-examination phase before an examination is performed. This document is applicable to molecular in vitro diagnostic examinations including laboratory developed tests performed by medical laboratories. It is also intended to be used by laboratory customers, in vitro diagnostics developers, and manufacturers, biobanks, institutions, and commercial organizations performing biomedical research, and regulatory authorities. This document does not cover pre-analytical workflow requirements for viable CTC cryopreservation and culturing. Different dedicated measures are taken for stabilizing CTCs genomic DNA and RNA that are not described in this document; they are covered in ISO 7552-1 and ISO 7552-2. NOTE 1 - The requirements given in this document can also be applied to other circulating rare cells (e.g. foetal cells). NOTE 2 - International, national or regional regulations or requirements can also apply to specific topics covered in this document.

ČSN P ISO/TS 15638-26 Tento dokument popisuje koncepční rámec pro aplikaci služby výměny informací o dynamickém nabíjení (pouze) těžkých elektrických nákladních vozidel napájenými bateriemi, v možném režimu neregulovaných i regulovaných komerčních nákladních vozidel v ekosystému TARV. Potenciální implementace TARV je obecně založena na definovaném sdílení informací mezi: - provozovateli vozidel s palubními systémy, - poskytovateli služeb palubních aplikací TARV, - silničním správcem. Tento dokument umožňuje nový způsob řízení spotřeby energie a specifikuje rámec pro dálkový sběr informací o směru a množství energie při dynamickém připojení vozidla k nabíjecí infrastruktuře. Informace slouží v případě této aplikační služby také dodavateli poskytované energie. Dokument popisuje informační toky týkající se sledování stavu energie ve vozidle v souvislosti s efektivním nabíjením ze sítě. Za jízdy je elektrické nákladní vozidlo podle své potřeby nabíjeno z infrastruktury poskytovatele elektrické energie (při pozemní komunikaci), anebo má-li vozidlo svoji baterii dobitou, při zpomalení poskytuje energii zpět do sítě (formou rekuperace). Tento dokument nespecifikuje fyzické vybavení pro tyto účely na straně poskytovatele energie ani na straně nákladního vozidla
