ČSN EN ISO 12696 This document specifies performance requirements for cathodic protection of steel in cement-based concrete, in both new and existing structures. It covers building and civil engineering structures, including carbon steel reinforcement and prestressed reinforcement embedded in the concrete. It is applicable to uncoated steel reinforcement and to organic-coated steel reinforcement. It is not applicable to reinforced concrete containing electrically conductive fibres (e.g. carbon or steel). This document applies to steel embedded in atmospherically exposed, buried, immersed and tidal elements of buildings or structures. This document is only applicable to the applications of cathodic protection to steel in concrete which are designed with the intention to, and can be demonstrated to, meet the criteria of protection specified in 8.6. This requires the provision of sufficient performance monitoring systems as specified in 6.3 to all parts of the structure intended to be protected, in order to assess the extent to which the criteria in 8.6 are met. This document does not apply to galvanic anodes or systems applied into patch repairs to reduce the effects of 'incipient anodes'. This document does also not apply to any form of cathodic protection systems or other electrochemical treatments that either cannot meet the requirements of 8.6 or are not provided with the performance monitoring systems (see 6.3) that are necessary to assess whether the criteria of protection specified in 8.6 are met. NOTE 1 - Annex A gives guidance on the principles of cathodic protection and its application to steel in concrete. NOTE 2 - This document, while not specifically intended to address cathodic protection of steel in any electrolyte except concrete, can be applied to cathodic protection of steel in other cementitious materials such as are found, for example, in early 20th century steel-framed masonry, brick and terracotta clad buildings. In such applications, additional considerations specific to these structures are required in respect of design, materials and installation of cathodic protection; however, the requirements of this document can be applied to these systems.

ČSN EN 16603-35-06 ECSS-E-ST-35-06 belongs to the Propulsion field of the mechanical discipline, and concerns itself with the cleanliness of propulsion components, sub-systems and systems The standard - defines design requirements which allow for cleaning of propulsion components sub-systems and systems and which avoid generation or unwanted collection of contamination, - identifies cleanliness requirements (e.g. which particle / impurity / wetness level can be tolerated), - defines requirements on cleaning to comply with the cleanliness level requirements, and the requirements on verification, - identifies the cleanliness approach, cleaning requirements, (e.g. what needs to be done to ensure the tolerable level is not exceeded, compatibility requirements), - identifies, specifies and defines the requirements regarding conditions under which cleaning or cleanliness verification takes place (e.g. compatibility, check after environmental test). The standard is applicable to the most commonly used propulsion systems and their related storable propellant combinations: Hydrazine (N2H4), Mono Methyl Hydrazine (CH3N2H3), MON (Mixed Oxides of Nitrogen), Nitrogen (N2), Helium (He), Propane (C3H8), Butane (C4H10) and Xenon (Xe). This standard is the basis for the European spacecraft and spacecraft propulsion industry to define, achieve and verify the required cleanliness levels in spacecraft propulsion systems. This standard is particularly applicable to spacecraft propulsion as used for satellites and (manned) spacecraft and any of such projects including its ground support equipment. External cleanliness requirements, e.g. outside of tanks, piping and aspects such as fungus and outgassing are covered by ECSS-Q-ST-70-01. This standard may be tailored for the specific characteristic and constraints of a space project in conformance with ECSS-S-ST-00.

ČSN EN 16603-50 This Standard specifies the requirements for the development of the endtoend data communications system for spacecraft. Specifically, this standard specifies: - The terminology to be used for space communication systems engineering. - The activities to be performed as part of the space communication system engineering process, in accordance with the ECSS-E-ST-10 standard. - Specific requirements on space communication systems in respect of functionality and performance. The communications links covered by this Standard are the space-ground (i.e. spacetoground and ground-to-space) and spacetospace links used during spacecraft operations, and the communications links to the spacecraft used during the assembly, integration and test, and operational phases. Spacecraft endtoend communication systems comprise components in three distinct domains, namely the ground network, the space link, and the space network. This Standard covers the components of the space link and space network in detail. However, this Standard only covers those aspects of the ground network that are necessary for the provision of the endtoend communication services. NOTE - Other aspects of the ground network are covered in ECSS-E-ST-70. This Standard may be tailored for the specific characteristics and constraints of a space project in conformance with ECSS-S-ST-00.

ČSN EN ISO 14708-6 This document specifies requirements that are applicable to implantable cardioverter defibrillators and CRT-Ds and the functions of active implantable medical devices intended to treat tachyarrhythmia. The tests that are specified in ISO 14708 are type tests and are to be carried out on samples of a device to show compliance. This document was designed for tachyarrhythmia pulse generators used with either endocardial leads or epicardial leads. At the time of this edition, the authors recognized the emergence of technologies that do not use endocardial or epicardial leads for which adaptations of this part will be required. Such adaptations are left to the discretion of manufacturers incorporating these technologies. This document is also applicable to some non-implantable parts and accessories of the devices (see Note 1). The characteristics of the implantable pulse generator or lead shall be determined by either the appropriate method detailed in this document or by any other method demonstrated to have accuracy equal to, or better than, the method specified. In the case of dispute, the method detailed in this document shall apply. Any aspect of an active implantable medical device intended to treat bradyarrhythmias or cardiac resynchronization is covered by ISO 14708-2. NOTE 1 - The device that is commonly referred to as an active implantable medical device can in fact be a single device, a combination of devices, or a combination of a device or devices and one or more accessories. Not all of these parts are required to be either partially or totally implantable, but there is a need to specify some requirements of non-implantable parts and accessories if they could affect the safety or performance of the implantable device. NOTE 2 - In this document, terms printed in italics are used as defined in Clause 3. Where a defined term is used as a qualifier in another term, it is not printed in italics unless the concept thus qualified is also defined.
