ČSN ETSI EN 300 175-7 V2.6.1 The present document is one of the parts of the specification of the Digital Enhanced Cordless Telecommunications (DECT) Common Interface (CI). The present document specifies the security architecture, the types of cryptographic algorithms required, the way in which they are to be used, and the requirements for integrating the security features provided by the architecture into the DECT CI. It also describes how the features can be managed and how they relate to certain DECT fixed systems and local network configurations. The security architecture is defined in terms of the security services which are to be supported at the CI, the mechanisms which are to be used to provide the services, and the cryptographic parameters, keys and processes which are associated with these mechanisms. The security processes specified in the present document are each based on one of three cryptographic algorithms: - an authentication algorithm; - a key stream generator for MAC layer encryption; and - a key stream generator plus a Message Authentication Code generator for CCM authenticated encryption. The architecture is, however, algorithm independent, and either the DECT standard algorithms, or appropriate proprietary algorithms, or indeed a combination of both can, in principle, be employed. The use of the employed algorithm is specified in the present document. Integration of the security features is specified in terms of the protocol elements and processes required at the Network (NWK) and Medium Access Control (MAC) layers of the CI. The relationship between the security features and various network elements is described in terms of where the security processes and management functions may be provided. The present document does not address implementation issues. For instance, no attempt is made to specify whether the DSAA or DSAA2 should be implemented in the PP at manufacture, or whether the DSAA, DSAA2 or a proprietary authentication algorithm should be implemented in a detachable module. Similarly, the present document does not specify whether the DSC or DSC2 should be implemented in hardware in all PPs at manufacture, or whether special PPs should be manufactured with the DSC, DSC2 or proprietary ciphers built into them. The security architecture supports all these options, although the use of proprietary algorithms may limit roaming and the concurrent use of PPs in different environments. Within the standard authentication algorithms, DSAA2, DSC2 and CCM are stronger than DSAA and DSC and provide superior protection. DSAA2 and DSC2 are based on AES [10] and were created in 2011. CCM is also based on AES [10] and was added to the standard in 2012. The present document includes New Generation DECT, a further development of the DECT standard introducing wideband speech, improved data services, new slot types and other technical enhancements. The present document also includes DECT Ultra Low Energy (ULE), a low rate data technology based on DECT intended for M2M applications with ultra low power consumption.

ČSN ETSI EN 300 468 V1.15.1 The present document specifies the Service Information (SI) data which forms a part of DVB bitstreams, in order that the user can be provided with information to assist in selection of services and/or events within the bitstream, and so that the Integrated Receiver Decoder (IRD) can automatically configure itself for the selected service. SI data for automatic configuration is mostly specified within ISO/IEC 13818 1 [18] as Program Specific Information (PSI). The present document specifies additional data which complements the PSI by providing data to aid automatic tuning of IRDs, and additional information intended for display to the user. The manner of presentation of the information is not specified in the present document, and IRD manufacturers have freedom to choose appropriate presentation methods. It is expected that Electronic Programme Guides (EPGs) will be a feature of Digital TV transmissions. The definition of an EPG is outside the scope of the present document (i.e. the SI specification), but the data contained within the SI specified in the present document may be used as the basis for an EPG. Rules of operation for the implementation of the present document are specified in ETSI TS 101 211 [i.2].

ČSN EN ISO 13940 ISO 13940:2015 defines a system of concepts for different aspects of the provision of healthcare. The core business in healthcare is the interaction between subjects of care and healthcare professionals. Such interactions occur in healthcare/clinical processes and are the justification for the process approach of ISO 13940:2015. To be able to represent both clinical content and clinical context, ISO 13940:2015 is related to a generic healthcare/clinical process model as well as comprehensive concept definitions and concept models for the clinical, management and resource aspects of healthcare services. In practice ISO 13940:2015 covers the concept definitions needed whenever structured information in healthcare is specified as a requirement. The definitions are intended to refer to the conceptual level only and not to details of implementation. ISO 13940:2015 will cover all levels of specifications in the development of logical reference models within the information viewpoint as a common basis for semantic interoperability on international, national or local levels, information systems, and information for specified types of clinical processes.

ČSN EN 12602 This European Standard is for prefabricated reinforced components of autoclaved aerated concrete to be used in building construction for: a) Structural elements: - loadbearing wall components; - retaining wall components; - roof components; - floor components; - linear components (beams and piers). b) Non-structural elements: - non-loadbearing wall components (partition walls); - cladding components (without fixtures) intended to be used for external facades of buildings; - small box culverts used to form channels for the enclosure of services; - components for noise barriers. Depending on the type and intended use of elements for which the components are utilized, the components can be applied - in addition to their loadbearing and encasing function - for purposes of fire resistance, sound insulation and thermal insulation indicated in the relevant clauses of this European Standard. Components covered by this standard are only intended to be subjected to predominantly non-dynamic actions, unless special measures are introduced in the relevant clauses of this European Standard. The term "reinforced" relates to reinforcement used for both structural and non-structural purposes. This European Standard does not cover: - rules for the application of these components in structures; - joints (except their strength and integrity E of resistance to fire); - fixtures; - finishes for external components, such as tiling. NOTE: AAC components may be used in noise barriers if they are designed to fulfil also the requirements of EN 14388.

ČSN EN ISO 10328 IMPORTANT - This International Standard is suitable for the assessment of the conformity of lower limb prosthetic devices/structures with the strength requirements specified in 4.4 of ISO 22523:2006 (see NOTE 1). Prosthetic ankle-foot devices and foot units on the market, which have demonstrated their compliance with the strength requirements specified in 4.4 of ISO 22523:2006 through submission to the relevant tests of ISO 10328:2006, need not be retested to ISO 22675:2016. WARNING - This International Standard is not suitable to serve as a guide for the selection of a specific lower limb prosthetic device/structure in the prescription of an individual lower limb prosthesis! Any disregard of this warning can result in a safety risk for amputees. This International Standard specifies procedures for static and cyclic strength tests on lower-limb prostheses (see NOTE 2) which typically produce compound loadings by the application of a single test force. The compound loads in the test sample relate to the peak values of the components of loading which normally occur at different instants during the stance phase of walking. The tests described in this International Standard comprise - principal static and cyclic tests for all components; - a separate static test in torsion for all components; - separate static and cyclic tests on ankle-foot devices and foot units for all ankle-foot devices as single components including ankle units or ankle attachments and all foot units as single components; - a separate static ultimate strength test in maximum knee flexion on knee joints and associated parts for all knee units or knee-shin-assemblies and adjacent components that normally provide the flexion stop on a complete prosthesis; - separate static and cyclic tests on knee locks for all mechanisms which lock the knee joint in the extended position of the knee unit or knee-shin-assembly. The tests described in this International Standard apply to specific types of ankle-disarticulation prostheses (see NOTE 2), to transtibial (below-knee), knee-disarticulation and transfemoral (above-knee) prostheses and to the distal (lower) part of hip-disarticulation and hemi-pelvectomy prostheses (see NOTE 3). NOTE 1: The tests can be performed on complete structures, on part structures or on individual components. NOTE 2: The tests only apply to ankle-disarticulation prostheses which include (foot) components of prosthetic ankle-foot devices taken from the normal production line. NOTE 3: The distal part comprises the knee unit, the ankle-foot device and all parts between. Tests on hip units are described in ISO 15032.

ČSN EN 61162-1 ed. 4 Tato norma obsahuje požadavky na datové spojení mezi námořními elektronickými přístroji, navigačním a radiokomunikačním zařízením, když jsou vzájemně propojeny pomocí vhodného systému. Norma je zaměřena na podporu jednosměrného sériového datového přenosu od jediného vysílače (mluvčího) k jednomu nebo více přijímačům (posluchačům). Tato data jsou v tisknutelné formě ASCII a mohou obsahovat informaci jako je poloha, rychlost, hloubka, přidělené kmitočty, atd. Typické zprávy mohou být dlouhé zhruba od 11 do maximálně 79 znaků a obvykle není požadována větší rychlost přenosu než jedna zpráva za sekundu. Elektrotechnické definice v této normě nezahrnují širokopásmové aplikace jako je radarové nebo video zobrazování nebo aplikace pro přenos rozsáhlých databází a souborů. S ohledem na to, že zde není poskytována žádná záruka kvality doručení zpráv a také schopnost korekce chyb je omezená, je třeba, aby tato norma byla s tímto vědomím používána u všech aplikací bezpečnostního charakteru. V aplikacích, kde je nutná vyšší přenosová rychlost, je třeba odkázat na normu IEC 61162-2. U aplikací, týkajících se zařízeních automatického identifikačního systému (AIS), je třeba odkázat na soubor norem IEC 62320.
