ČSN EN 1279-3 Tato norma stanovuje požadavky a popisuje zkušební metody pro prvky utěsnění okraje a vložné prvky. To zahrnuje identifikaci, stanovení fyzikálních vlastností a hodnocení charakteristik pro použití v rámci pravidel náhrady podle EN 1279-1:2018. Pro účely prokázání, že prvky utěsnění okraje umožní, aby bylo izolační sklo ve shodě s požadavky uvedenými v EN 1279-1:2018, kapitola 6, se využijí též EN 1279-2:2018 a EN 1279-3:2018.

ČSN EN 12697-31 This document specifies the method for compaction of cylindrical specimens of bituminous mixtures using a gyratory compactor. The method is used for: - determination of the air voids content of a mixture for a given number of gyrations or derivation of a curve density (or void content) versus number of gyrations; - preparation of specimens of given height and/or at a predetermined density, for subsequent testing of their mechanical properties. Annex A and Annex B describe method of complying for the equipment. This document applies to bituminous mixtures (both those made up in laboratory and those resulting from work site sampling), with an upper aggregate size not larger than 31,5 mm.

ČSN EN ISO 21084 This document specifies the method for the determination of extractable alkylphenols (AP) without derivatization step in textile and textile products.

ČSN EN ISO 13438 This document specifies a screening test method for determining the resistance of geotextiles and geotextile-related products to oxidation. The test is applicable to products as follows: - Method A for material consisting solely in polypropylene (PP), polyethylene (PE), polyamide (PA), aramide (AR); - Method B for material consisting solely in polyvinyl alcohol (PVAL). The data are suitable for screening purposes but not for deriving performance data such as lifetime, unless supported by further evidence.

ČSN EN ISO 12957-1 This document specifies an index test method to determine the friction characteristics of geosynthetics in contact with a standard sand as described in EN 196-1, i.e. with a specified density and moisture content, under a normal stress and at a constant rate of displacement, using a direct shear apparatus. The same testing procedure can be used with any type of soil with the density and moisture content that are required to evaluate the performance under specific conditions or with another geosynthetic under a normal stress and at a constant rate of displacement, using a direct shear apparatus. The procedure can also be used for testing geosynthetic barriers.

ČSN EN ISO 23753-2 This document specifies a method for determining activity of dehydrogenases in soil, using 2-(4-iodophenyl)-3-(4-nitrophenyl)-5-phenyltetrazolium chloride (INT)[1]-[5]. As the INT reduction is less sensitive to O2, the method is more robust than the TTC-method described in ISO 23753-1.

ČSN EN ISO 23753-1 This document specifies a method for determining the activity of dehydrogenases enzymes in soil using 2,3,5-triphenyltetrazolium chloride (TTC).

ČSN EN ISO 7886-4 This document specifies requirements for sterile single-use hypodermic syringes made of plastic and rubber materials with or without needle, and intended for the aspiration of fluids or for the injection of fluids immediately after filling and of design such that the syringe can be rendered unusable after use. This document is not applicable to syringes made of glass [specified in ISO 595 (withdrawn)], auto-disable syringes for fixed dose immunization (ISO 7886-3) and syringes designed to be pre-filled. It does not address compatibility with injection fluids. Other standards can be applicable when syringes are used for any other intended purpose than those specified in this document. NOTE - Syringes designed to reduce the risk of needle-stick injuries can also comply with this document with regard to their re-use prevention properties, but it is stressed that anti-needle-stick properties of syringes are not in themselves addressed in this document.

ČSN ETSI EN 319 521 V1.1.1 Tento dokument stanovuje obecně použitelné požadavky politiky a bezpečnosti na poskytovatele služeb elektronického doporučeného doručování (ERDSP) včetně služeb, které poskytují. Tento dokument je použitelný pro: - požadavky politiky a bezpečnosti na poskytovatele ERDSP a ERDSP kvalifikované v EU; - obecné a bezpečnostní požadavky na služby elektronického doporučeného doručování (ERDS) a ERDS kvalifikované v EU z hlediska integrity zpráv; ochrana před ztrátou, odcizením, poškozením nebo neoprávněnou změnou přenášených dat; silná identifikace odesílatele a příjemce; časová reference; a doklad o odeslání a přijetí dat. Tento dokument nestanovuje požadavky na propojení.

ČSN P CEN/TS 17313 This document provides a description for voluntarily consenting vendors (subsequently referred to as 'participating service providers'), who wish to provide TPS-eCall service in an open market environment, where users can select and change the service provider. It focusses on the use case 'TPS-eCall service', as standardized in EN 16102, only (and for clarification, does not apply in respect of 112-eCall, where no TPS provider is involved.) The document determines the preconditions, requirements and functional means needed in order that users of a TPS-eCall service can choose and change her/his preferred service provider (TPSP) out of a range of available TPSPs, who are participating in the open market provisions determined in this specification. Outside the scope of this document are: a) any commercial considerations (e.g. whether the service is offered for free or a charged service or part of a commercial service package offer), b) any contractual considerations (e.g. how a service contract between an user and a TPSP is established), c) any IT-security related issues in conjunction with the TPS in-vehicle system, d) any considerations regarding communication costs (for voice and data) related to the TPS-eCall service e) any PSAP related considerations (towards the PSAPs there is no impact related to provider change, since any TPSP needs to negotiate acceptance of its service offering with the PSAPs in the countries where the service is provided, before such service can be provided).
