ČSN EN IEC 60118-16 Tato část normy uvádí definice běžných funkcí sluchadel, jako je redukce šumu nebo redukce zpětné vazby atd. Uvažují se pouze akustické vstupy. Binaurální funkce nejsou v současné době v tomto dokumentu zahrnuty. Kromě toho jsou popsány postupy měření k ověření funkcí sluchadel. Cílem není hodnotit výkonnost funkcí, ale ověřit jejich existenci a funkčnost. Definice a postupy jsou navíc co nejobecnější, aby bylo možné tento dokument použít pro různé typy slucha-del, například pro sluchadla se vzdušným vedením nebo sluchadla s kostním vedením. Za tímto účelem je přijata obecná definice pojmu "sluchadlo" uvedená v IEC 60118-0 a tento dokument neodkazuje na žádný konkrétní simulátor ucha nebo akustickou spojku, ale používá obecnou definici spojky. Pokud však obecný pohled není použitelný nebo vede k nejasné nebo složité formulaci, uvažuje se situace pouze pro sluchadlo se vzdušným vedením. Nicméně je uvedeno vysvětlení, jak lze tento dokument použít pro sluchadla, která nepoužívají vzdušné vedení.

ČSN ETSI EN 300 175-6 V2.9.1 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 identities and addressing structure of the Digital Enhanced Cordless Telecommunications (DECT) Common Interface (CI). There are four categories of identities to be used for identification and addressing in a general DECT environment. These four categories are: - Fixed Part (FP) identities; - Portable Part (PP) identities; - connection-related identities; - equipment-related identities. Fixed part identities and portable part identities are used for: - access information from fixed parts to portable parts; - access requests from portable parts; - identification of portable parts; - identification of fixed parts and radio fixed parts; - paging; - billing. These identities support: - different environments, such as residential, public or private; - supply to manufacturers, installers, and operators of globally unique identity elements with a minimum of central administration; - multiple access rights for the same portable; - large freedom for manufacturers, installers, and operators to structure the fixed part identities, e.g. to facilitate provision of access rights to groups of DECT systems; - roaming agreements between DECT networks run by the same or different owners/operators; - indication of handover domains; - indication of location areas, i.e. paging area; - indication of subscription areas of a public service. The present document also provides for length indicators and other messages that can override the default location and/or paging area and domain indications given by the structure of the identities. Connection related identities are used to identify the protocol instances associated with a call and are used for peer to peer communication. Equipment related identities are used to identify a stolen PP and to derive a default identity coding for PP emergency call set up. Coding of identity information elements for higher layer messages is found in ETSI EN 300 175 5 [5], clause 7.7. User authentication and ciphering need additional key information and is outside the scope of the present document, but is covered in other parts of ETSI EN 300 175 [1] to [8], e.g. ETSI EN 300 175-7 [7]. 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.

ČSN EN ISO/IEEE 11073-40102 For Personal Health Devices (PHDs) and Point-of-Care Devices (PoCDs), a security baseline of application layer cybersecurity mitigation techniques is defined by this standard for certain use cases or for times when certain criteria are met. The mitigation techniques are based on an extended confidentiality, integrity, and availability (CIA) triad and are described generally to allow manufacturers to determine the most appropriate algorithms and implementations. A scalable information security toolbox appropriate for PHD/PoCD interfaces is specified that fulfills the intersection of requirements and recommendations from the National Institute of Standards and Technology (NIST) and the European Network and Information Security Agency (ENISA). A mapping of this standard to the NIST cybersecurity framework; IEC TR 80001-2-2; and the Spoofing, Tampering, Repudiation, Information Disclosure, Denial of Service, and Elevation of Privilege (STRIDE) classification scheme is defined.

ČSN EN 15112 This document provides information on methods suitable for assessing the likelihood of leakage due to external corrosion of well casings and to evaluate the need for cathodic protection, as well as methods of providing cathodic protection to the external part of these wells in contact with the soil. It also defines requirements for monitoring of performance of CP systems. Onshore and offshore wells are included in the scope. However, for offshore wells where protection is provided by anodes on the wellhead structure, it is recognized that it might not be practical to achieve full protection of well casings. This document applies to any gas, oil or water well with metallic casing, whether cemented or not. However, in special conditions (shallow casings: e.g. 50 m, and homogeneous soil), EN 12954 can be used to achieve the cathodic protection and assess its efficiency. The general requirements of EN 12954 apply; this document details additional, specific, requirements for CP of well casings. This document applies to production and injection wells. References later in this document to production also apply to injection.
