ČSN EN ISO 11073-10441 Within the context of the ISO/IEEE 11073 family of standards for device communication, this standard establishes a normative definition of the communication between personal cardiovascular fitness and activity monitoring devices and managers (e.g., cell phones, personal computers, personal health appliances, and set top boxes) in a manner that enables plug-and-play interoperability. It leverages appropriate portions of existing standards including ISO/IEEE 11073 terminology and information models. It specifies the use of specific term codes, formats, and behaviors in telehealth environments restricting optionality in base frameworks in favor of interoperability. This standard defines a common core of communication functionality for personal telehealth cardiovascular fitness and activity monitor devices. In this context, cardiovascular fitness and activity monitor devices are being used broadly to cover cardiovascular fitness and activity monitor devices that measure physical actions and the body's various physiological re-sponses to that activity.

ČSN EN 60728-101 This part of IEC 60728 is applicable to any cable network (including individual receiving systems) distributing only digital channels having in the forward path a coaxial cable output and primarily intended for television and sound signals operating between about 30 MHz and 3 000 MHz. This standard specifies the basic methods of measurement of the operational characteristics of a cable network having coaxial cable outputs in order to assess the performance of these systems and their performance limits.

ČSN ETSI EN 300 401 V2.1.1 The present document establishes a broadcasting standard for the Digital Audio Broadcasting (DAB) system designed for delivery of high-quality digital audio and video programmes and data services for mobile, portable and fixed reception from terrestrial transmitters in the Very High Frequency (VHF) frequency bands as well as for distribution through cable networks. The DAB system is designed to provide spectrum and power efficient techniques in terrestrial transmitter network planning, known as the Single Frequency Network (SFN) and the gap filling technique. The DAB system meets the required sharing criteria with other radiocommunication services. The present document defines the DAB transmission signal. It includes the coding algorithms for multiplexing of audio and video programmes and data services, channel coding and modulation. Provision is also made for transmission of additional data services which may be programme related or not, within the limit of the total system capacity. The present document provides information on the system configuration which includes information about the ensembles, services, service components and linking of them. The present document describes the nominal characteristics of the emitted DAB signal. The aspects related to the receiver design are outside the scope of the present document.

ČSN EN 62433-2 ed. 2 Tato norma specifikuje makromodely integrovaných obvodů (IO) určené pro simulaci elektromagnetických emisí šířených vedením na desce plošných spojů. Model je obvykle nazýván Emisní model integrovaného obvodu - emise vedením (ICEM-CE). ICEM-CE model může být použit pro modelování analogových a digitálních integrovaných obvodů. Emise vedením můžeme rozdělit do dvou skupin podle jejich původu a to emise šířené přes napájecí vývody a zemnící referenční struktury a emise šířené přes vstupní/výstupní vývody. Tato norma definuje struktury a komponenty makromodelů pro simulaci EMI s ohledem na vnitřní chování integrovaných obvodů. Tato norma má dvě hlavní části: - první je elektrický popis prvků makromodelu ICEM-CE; - druhá nabízí univerzální formát výměny dat nazývaný CEML založený na XML. Tento formát umožňuje kódování ICEM-CE ve více použitelné a všeobecné podobě pro simulace emisí šířených vedením.

ČSN EN ISO 16530-1 This document is applicable to all wells that are operated by the petroleum and natural gas industry. This document is applicable to any well, or group of wells, regardless of their age, location (including onshore, subsea and offshore wells) or type (e.g. naturally flowing, artificial lift, injection wells). This document is intended to assist the petroleum and natural gas industry to effectively manage well integrity during the well life cycle by providing: - minimum requirements to ensure management of well integrity; and - recommendations and techniques that well operators can apply in a scalable manner based on a well's specific risk characteristics. Assuring well integrity comprises two main building blocks: the first is to ensure well integrity during well design and construction, and the second is to manage well integrity throughout the remaining well life thereafter. This document addresses each stage of the well life cycle, as defined by the six phases in a) to f), and describes the deliverables between each phase within a Well Integrity Management system.

ČSN EN 61709 ed. 3 This document gives guidance on the use of failure rate data for reliability prediction of electric components used in equipment. The method presented in this document uses the concept of reference conditions which are the typical values of stresses that are observed by components in the majority of applications. Reference conditions are useful since they provide a known standard basis from which failure rates can be modified to account for differences in environment from the environments taken as reference conditions. Each user can use the reference conditions defined in this document or use their own. When failure rates stated at reference conditions are used it allows realistic reliability predictions to be made in the early design phase. The stress models described herein are generic and can be used as a basis for conversion of failure rate data given at these reference conditions to actual operating conditions when needed and this simplifies the prediction approach. Conversion of failure rate data is only possible within the specified functional limits of the components. This document also gives guidance on how a database of component failure data can be constructed to provide failure rates that can be used with the included stress models. Reference conditions for failure rate data are specified, so that data from different sources can be compared on a uniform basis. If failure rate data are given in accordance with this document then additional information on the specified conditions can be dispensed with. This document does not provide base failure rates for components - rather it provides models that allow failure rates obtained by other means to be converted from one operating condition to another operating condition. The prediction methodology described in this document assumes that the parts are being used within its useful life. The methods in this document have a general application but are specifically applied to a selection of component types as defined in Clauses 6 to 20 and I.2.
