ČSN EN 13368-2 Tato evropská norma specifikuje metodu chromatografického stanovení železa chelatovaného každým individuálním orto(hydroxy)-orto(hydroxy) izomerem chelatačního činidla [o,o] EDDHA, [o,o] EDDHMA a HBED v hnojivech obsahujících jednu nebo více těchto látek, kromě směsí [o,o] EDDHMA a HBED. Tato metoda umožňuje identifikaci a stanovení celkové koncentrace vodorozpustného železa chelatovaného těmito chelatačními činidly. Také, po derivatizaci pomocí Fe, může být stanoveno rozpuštěné množství chelatačního činidla, jsou-li jiné mikroelementy mimo Fe, přítomny v hnojivech obsahujících [o,o] EDDHA, [o,o] EDDHMA nebo HBED. Tato metoda je použitelná pro hnojiva ES uvedená v nařízení (ES) č. 2003/2003 [4]. Je použitelná pro stanovení hmotnostního zlomku chelatovaného kovu nejméně 0,625 %.

ČSN EN 13588 Tato evropská norma určuje metodu pro měření koheze asfaltových pojiv při teplotách v rozmezí (+10 °C) až (+70 °C) a pro vyjádření vztahu mezi kohezí a teplotou. U ředěných a fluxovaných asfaltů a u asfaltových emulzí může zkoušené pojivo být výsledkem specifické destilace, zpětného získání a/nebo stabilizace. Metoda může být též použita na pojiva, která byla podrobena specifickému postupu stárnutí. VÝSTRAHA - Použití této normy může být spojeno s používáním nebezpečných materiálů, pracovních postupů a zařízení. Tato norma adresně neupozorňuje na všechny bezpečnostní problémy spojené s jejím použitím. Uživatel této normy je zodpovědný za to, že předem provede příslušná opatření z hlediska bezpečnosti a ochrany zdraví a stanoví pro její použití regulační omezení.

ČSN EN 16766 This European Standard sets the requirements for bio-based solvents in terms of their bio-based content, their technical properties and test methods. It lays down the characteristics and details for assessment of bio-based solvents that: - are fit for purpose in terms of performance related properties; - comply with the health, safety and environmental requirements which apply generally to solvents; and - are derived from biomass. This European Standard specifies solvent classes, based on the percentage of bio-based carbon content and bio-based content. NOTE: EN 16575 defines the term "bio-based" as derived from biomass and clarifies that "bio-based" does not imply "biodegradable". In addition, "biodegradable" does not necessarily imply the use of "bio-based" material. In addition, this document sets requirements on information to be provided regarding sustainability aspects.

ČSN EN ISO 20108 This document sets out requirements for the quality and transmission of sound and image input to interpreters and specifies the characteristics of the audio and video signals. The components of typical interpreting systems are specified in ISO 20109. Together with either permanent (see ISO 2603) or mobile (see ISO 4043) booths, these interpreting systems form the interpreters' working environment. In addition to setting out the requirements for on-site interpreting, where participants (speakers and members of the audience) and interpreters are at the same location, this document specifies requirements for different varieties of distance interpreting situations in which the interpreters are not at the same location as one or more of the conference participants. This document also addresses the work of manufacturers and providers of simultaneous interpreting equipment and technical staff. In conjunction with either ISO 2603 or ISO 4043, this document and ISO 20109 provide the relevant requirements both for the quality and transmission of sound and image provided to interpreters and for the equipment needed in the booths, the conference room and the distant site(s).

ČSN EN ISO 9696 This document specifies a method for the determination of gross alpha activity in non-saline waters for alpha-emitting radionuclides which are not volatile up to 350 °C. The method is applicable to raw and potable waters. The range of application depends on the amount of total soluble salts in the water and on the performance characteristics (background count rate and counting efficiency) of the counter. It is the laboratory's responsibility to ensure the suitability of this method for the water samples tested.

ČSN EN 342 Tato evropská norma stanoví požadavky a zkušební metody pro užitné vlastnosti oděvních souprav (tj. dvoudílných obleků nebo kombinéz, pro oděvní součásti platí EN 14058) k ochraně proti účinkům chladného prostředí s teplotou rovnající se -5 °C nebo nižší. Tyto účinky zahrnují nejen nízkou teplotu vzduchu, ale také vlhkost a rychlost proudění vzduchu. Ochranné vlastnosti a požadavky na obuv, rukavice a samostatné pokrývky hlavy jsou z oblasti působnosti této normy vyňaty.

ČSN EN ISO 11508 This document specifies two methods for the determination of particle density of soils calculated from the mass and the volume of soil particles. The first method (4.1) is applicable to fine soil (2 mm diameter). The particle density can be used for the calculation of the proportion of solids and of the porosity of soil layers in combination with the procedure given in ISO 11272.
