ČSN EN 14789 This European Standard specifies the standard reference method (SRM) based on the paramagnetic principle for the determination of the oxygen concentrations in flue gases emitted to the atmosphere from ducts and stacks. It includes the sampling and the gas conditioning system as well as the analyser. This European Standard specifies the performance characteristics to be determined and the performance criteria to be fulfilled by portable automated measuring systems (P-AMS) based on this measurement method. It applies to periodic monitoring and the calibration or control of automated measuring systems (AMS) permanently installed on a stack, for regulatory or other purposes. This European Standard specifies criteria for demonstration of equivalence of an alternative method (AM) to the SRM by application of EN 14793:2017. This European Standard has been validated during field tests on waste incineration, co-incineration and large combustion plants and on a recognized test bench. It has been validated for sampling periods of 30 min in the range from 3 % to 21 %. Oxygen concentration values, expressed as volume concentrations, are used to allow results of emission measurements to be standardised to the oxygen reference concentration and dry gas conditions required e.g. by EU Directive 2010/75/EC on industrial emissions. NOTE: The characteristics of installations, the conditions during field tests and the values of repeatability and reproducibility in the field are given in Annex A.

ČSN EN 14790 This European Standard specifies the standard reference method (SRM) based on a sampling system with a condensation/adsorption technique to determine the water vapour concentration in the flue gases emitted to atmosphere from ducts and stacks. This European Standard specifies the performance characteristics to be determined and performance criteria to be fulfilled by measuring systems based on the measurement method. It applies to periodic monitoring and to the calibration or control of automated measuring systems (AMS) permanently installed on a stack, for regulatory or other purposes. This European Standard specifies criteria for demonstration of equivalence of an alternative method to the SRM by application of EN 14793:2017. This European Standard is applicable in the range of water vapour content from 4 % to 40 % as volume concentrations and of water vapour mass concentration from 29 g/m3 to 250 g/m3 as a wet gas, although for a given temperature the upper limit of the method is related to the maximum pressure of water in air or in the gas. In this European Standard all the concentrations are expressed at standard conditions (273 K and 101,3 kPa). NOTE 1: For saturated conditions the condensation/adsorption method is not applicable. Some guidance is given in this European Standard to deal with flue gas when droplets are present. This European Standard has been validated during field tests on waste incineration, co-incineration and large combustion plants. It has been validated for sampling periods of 30 min in the volume concentration range of 7 % to 26 %. NOTE 2: The characteristics of installations, the conditions during field tests and the values of repeatability and reproducibility in the field are given in Annex A.

ČSN EN 14793 This European Standard specifies a procedure to demonstrate the equivalence of an alternative method (AM) with the reference method (RM) or the standard reference method (SRM), both implemented to determine the same measurand. In particular, this European Standard provides the statistical tools and different criteria to evaluate the alternative method. This does not release the body performing the equivalence testing from bearing technical and analytical judgement on the evaluation of the different criteria. Three steps are required for demonstration of equivalence: - description of the alternative method and setting of the field of application (measurement range and type of gas matrix); - determination of the performance characteristics of the alternative method and calculation of the expanded uncertainty where appropriate and check of compliance with the maximum expanded uncertainty allowed for the reference method; - check of repeatability and lack of systematic deviation of the alternative method in the field or on a recognized test bench in comparison with the reference method for the type of matrix defined in the field of equivalence. This European Standard requires that a reference method has been defined and validated. This European Standard only considers the case of linear quantitative methods. This European Standard is applicable to manual and automated methods. This European Standard has been drawn up for laboratories working in air quality measurements and consequently an example taken from this sector are presented in Annex A.

ČSN ETSI EN 302 066 V2.1.1 The present document specifies the requirements for Ground- and Wall- Probing Radar imaging systems applications. Ground Probing Radars (GPR) and Wall Probing Radars (WPR) are used in survey and detection applications. The scope is limited to GPR and WPR radars, in which the system is in close proximity to the materials being investigated. It does not include radars operated from aircraft or spacecraft. The GPR/WPR applications in the present document are not intended for communications purposes, and the intended signal is not radiated into free space. NOTE: Equipment covered by the present document is intended to be used by competent professional personnel. Equipment covered by the present document operates in accordance with ECC/DEC(06)08 "ECC Decision of 1 December 2006 on the conditions for use of the radio spectrum by Ground- and Wall- Probing Radar (GPR/WPR) imaging systems" [i.2].

ČSN EN 16120+A2 This European Standard specifies safety requirements and test methods for chair mounted seats intended to be positioned on an adult chair to raise the sitting position of a child able to sit unaided up to an age of 36 months or a maximum weight of 15 kg. This European Standard does not apply to cushions, pads and to products only aimed at restraining the child on a chair without raising the child's sitting position.

ČSN EN ISO 21298 This International Standard defines a model for expressing functional and structural roles and populates it with a basic set of roles for international use in health applications. Roles are gene-rally assigned to entities that are actors. This will focus on roles of persons (e.g. the roles of he-alth professionals) and their roles in the context of the provision of care (e.g. subject of care). Roles can be structural (e.g.: licensed general practitioner, non-licensed transcriptionist) or functional (e.g.: a provider who is a member of a therapeutic team, an attending physician, prescriber, etc). Structural roles are relatively static, often lasting for many years. They deal with relationships between entities expressed at a level of complex concepts. Functional roles are bound to the realisation of actions and are highly dynamic. They are normally expressed at a decomposed level of fine-grained concepts. The role concepts defined in this standard are refe-renced and reused in many international standards created, e.g., by ISO, CEN, HL7 International. Examples are ISO 22600 "Health informatics - Privilege management and access control", HL7 International "HL7 Healthcare privacy and security classification system (HCS)", HL7 International "HL7 Security and privacy ontology", HL7 International "The HL7 RBAC Healthcare Permission Catalog" or HL7 International "HL7 Composite security and privacy domain analysis model DSTU".Roles addressed in this International Standard are not restricted to privilege management purposes, though privilege management and access control is one of the applications of this International Standard. This standard does not address specifications related to permissions. This document treats the role and the permission as separate constructs. Further details regarding the relationship with permissions, policy, and access control are provided in ISO 22600.
