ČSN ISO 20035 Kooperativní adaptivní tempomat (CACC) je rozšířením stávajícího řízení s adaptivním tempomatem s použitím bezdrátové komunikace s vpředu jedoucím vozidlem (V2V) a/nebo s infrastrukturou (I2V). Tento dokument popisuje data vozidel V2V i infrastruktury I2V. Při využití dat CACC lze použít menší časový rozestup mezi vozidly a přesnější řízení odstupu, což umožňuje zvýšit dopravní propustnost a snížit spotřebu paliva.

ČSN EN IEC 61000-3-2 ed. 5 Tato část souboru norem se zabývá omezením proudů harmonických injektovaných do veřejné napájecí sítě. Stanovuje meze harmonických složek vstupního proudu, které mohou být vytvářeny zařízením zkoušeným za stanovených podmínek. Tato část IEC 61000 se týká elektrických a elektronických zařízení se jmenovitým vstupním fázovým proudem až do 16 A včetně, u nichž se předpokládá připojení do veřejných distribučních sítí nízkého napětí. Zařízení pro obloukové svařování, které není profesionálním zařízením, se jmenovitým vstupním fázovým proudem do 16 A včetně, je v této normě zahrnuto. Zařízení pro obloukové svařování určené pro profesionální použití specifikované v IEC 60974-1 není v této normě zahrnuto a může být předmětem omezení instalace podle IEC 61000 3 12. Zkoušky podle této normy jsou typové zkoušky. Pro sítě se jmenovitými napětími menšími než, ale ne rovnými 220 V (fázový vodič - nulový vodič) nebyly meze zatím uvažovány.

ČSN EN ISO 11704 This document specifies a method for the determination of gross alpha and gross beta activity concentration for alpha- and beta-emitting radionuclides using liquid scintillation counting (LSC). The method is applicable to all types of waters with a dry residue of less than 5 g/l and when no correction for colour quenching is necessary. Gross alpha and gross beta activity measurement is not intended to give an absolute determination of the activity concentration of all alpha- and beta-emitting radionuclides in a test sample, but is a screening analysis to ensure particular reference levels of specific alpha and beta emitters have not been exceeded. This type of determination is also known as gross alpha and beta index. Gross alpha and beta analysis is not expected to be as accurate nor as precise as specific radionuclide analysis after radiochemical separations. The method covers non-volatile radionuclides below 80 °C, since some gaseous or volatile radionuclides (e.g. radon and radioiodine) can be lost during the source preparation. The method is applicable to test samples of drinking water, rain water, surface and ground water as well as cooling water, industrial water, domestic and industrial waste water after proper sampling and test sample preparation (filtration when necessary and taking into account the amount of dissolved material in the water). The method described in this document is applicable in the event of an emergency situation, because the results can be obtained in less than 4 h by directly measuring water test samples without any treatment. It is the laboratory's responsibility to ensure the suitability of this test method for the water samples tested.

ČSN P CEN/TS 17274 This document provides protocol guidelines for determining explosivity and flammability characteristics of powders containing manufactured nano-objects. These explosivity and flammability characteristics are needed for safety data sheets for safe storage, handling and transport of any powder. In particular, this document will provide protocol guidelines concerning: - the determination of flammability characteristics of powders containing nano-objects with regard to sensitivity to ignition sources; - the ability of a powder containing nano-objects to generate an explosive atmosphere and the assessment of its explosion characteristics. This document is not suitable for use with recognized explosives, such as gunpowder and dynamite, explosives which do not require oxygen for combustion, or substances or mixtures of substances which may under some circumstances behave in a similar manner. Where any doubt exists about the existence of hazard due to explosive properties, it is best to seek expert advice.

This document specifies acceptance levels and calibration procedures. It can also be applicable to the testing of circular hollow sections. NOTE - As an alternative, see ISO 10893-6 for film-based radiographic X-ray testing.

ČSN P CEN/TS 17249-4 In respect of 112-eCall (operating requirements defined in EN 16072), this document defines additional specifications for the provision of eCall for agricultural/forestry vehicles. As with the existing provisions for eCall for Category M1/N1 vehicles, these systems are specified within the paradigm of being OEM fit equipment supplied with new vehicles. NOTE 1 - The provision of eCall for vehicles via the aftermarket (post sale and registration) will be the subject of other work, and in respect of the operational requirements for any such aftermarket solutions for agricultural/forestry vehicles, will use the specifications of this Technical Specification as a principle reference point. NOTE 2 - The 112-eCall paradigm involves a direct call from the vehicle to the most appropriate PSAP. (Third party service provision by comparison, involves the support of an intermediary third party service provider before the call is forwarded to the PSAP). The specifications herein relate only to the provision of 112-eCall or IMS-112-eCall, and do not provide specifications for third party service provision of eCall.
