ČSN P CEN/TS 17642 Within the context of 112-eCall (operating requirements defined in EN 16072), this document defines specifications for the provision of 112-eCall for regulated commercial vehicles, including rigid body trucks and variants thereof, prime mover and trailer combinations (sometimes called "semi's", road trains [one prime mover with multiple trailers]) and other regulated commercial vehicles (for example vans carrying medical supplies or radioactive material). The work of CEN/TS 16405 is adopted and extended in this document. (A revised version of CEN/TS 16405 will remain the principal reference document for the content and definition of the commercial vehicle optional additional data set). As with the existing provisions for 112-eCall for Category M1/N1 vehicles, these are specified within the paradigm of being OEM fit equipment supplied with new vehicles. The scope of this specification is limited to the provision of eCall from a commercial vehicle prime mover /rigid body truck) designed for conveying cargo. (UNECE Category N). This document specifies the requirements for the use of 112-eCall by a commercial vehicle prime mover /rigid body truck and defines the interface between the PSAPs and an external transport database. Unless superseded by European Regulation at some future date, all data schemas specified herein and defined in a revision of CEN/TS 16405 are "Optional Additional Data" (OAD) concepts, as enabled in accordance with EN 15722:2020 as part of the minimum set of data As OAD they, and the elements within them, are, by definition, "optional" with use at the discretion of the operator of the vehicle. This document defines how eCall for commercial vehicles is expected to interact with the future eFTI standards and the prerequisites for these standards to allow the access to the relevant freight information for the PSAPSs in case of an eCall. NOTE 1 - The provision of eCall from IVS located within trailers is not included in this document, but could be the subject of a further standards deliverable. NOTE 2 - 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 commercial vehicles, will use this document as a principle reference point. NOTE 3 - 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, although in the case of 112-eCall for commercial vehicles, links to third party provision of service aspects (such as cargo contents) could be required.

ČSN ISO 3089 Tato mezinárodní norma specifikuje s odkazem na ISO 230-1 geometrické zkoušky a odpovídající tolerance pro samostředicí ručně ovládaná sklíčidla pro obráběcí stroje s více než dvěma čelistmi. Tento typ sklíčidla má čelisti známé jako "jednodílné tvrdé čelisti", jejichž relativně velký zdvih umožňuje rychlé přizpůsobení nejrůznějším velikostem obrobků bez demontáže. Tato mezinárodní norma se zabývá pouze kontrolami přesnosti otáčení sklíčidla rovnání a vystředění obrobků. Není použitelná pro jiné dynamické veličiny, jako je měření vyvažování nebo měření uchopovacích sil.

ČSN EN ISO 18589-1 This document specifies the general requirements to carry out radionuclides tests, including sampling of soil including rock from bedrock and ore as well as of construction materials and products, pottery, etc. using NORM or those from technological processes involving Technologically Enhanced Naturally Occurring Radioactive Materials (TENORM) e.g. the mining and processing of mineral sands or phosphate fertilizer production and use. For simplification, the term "soil" used in this document covers the set of elements mentioned above. This document is addressed to people responsible for determining the radioactivity present in soils for the purpose of radiation protection. This concerns soils from gardens and farmland, urban or industrial sites, as well as soil not affected by human activities. This document is applicable to all laboratories regardless of the number of personnel or the extent of the scope of testing activities. When a laboratory does not undertake one or more of the activities covered by this document, such as planning, sampling or testing, the requirements of those clauses do not apply. This document is to be used in conjunction with other parts of ISO 18589 that outline the setting up of programmes and sampling techniques, methods of general processing of samples in the laboratory and also methods for measuring the radioactivity in soil. Its purpose is the following: - define the main terms relating to soils, sampling, radioactivity and its measurement; - describe the origins of the radioactivity in soils; - define the main objectives of the study of radioactivity in soil samples; - present the principles of studies of soil radioactivity; - identify the analytical and procedural requirements when measuring radioactivity in soil. This document is applicable if radionuclide measurements for the purpose of radiation protection are to be made in the following cases: - initial characterization of radioactivity in the environment; - routine surveillance of the impact of nuclear installations or of the evolution of the general territory; - investigations of accident and incident situations; - planning and surveillance of remedial action; - decommissioning of installations or clearance of materials.

ČSN EN ISO 18589-6 This document provides a method that allows an estimation of gross radioactivity of alpha- and beta-emitters present in soil samples. It applies, essentially, to systematic inspections based on comparative measurements or to preliminary site studies to guide the testing staff both in the choice of soil samples for measurement as a priority and in the specific analysis methods for implementation. The gross alpha or beta radioactivity is generally different from the sum of the effective radioactivities of the radionuclides present since, by convention, the same alpha counting efficiency is assigned for all the alpha emissions and the same beta counting efficiency is assigned for all the beta emissions. Soil includes rock from bedrock and ore as well as construction materials and products, potery, etc. using naturally occurring radioactive materials (NORM) or those from technological processes involving Technologically Enhanced Naturally Occurring Radioactive Materials (TENORM), e.g. the mining and processing of mineral sands or phosphate fertilizer production and use. The test methods described in this document can also be used to assess gross radioactivity of alpha- and beta-emitters in sludge, sediment, construction material and products following proper sampling procedure. For simplification, the term "soil" used in this document covers the set of elements mentioned above.
