ČSN EN IEC 61591 ed. 3 This document applies to cooking fume extractors incorporating a fan for the recirculation or extraction mode situated in a household kitchen. It can also be used for cooking fume extractors where the fan is mounted separately from the appliance, but controlled by the appliance when the fan is defined in the technical documentation (e.g. name plate data) and instructions for installation. This document deals also with down-draft systems arranged besides, behind or under the cooking appliance. This document defines the main performance characteristics of these appliances, which are of interest to the user, and specifies methods for measuring these characteristics. This document does not specify a classification or ranking for performance.

ČSN EN ISO 527-4 This document specifies the test conditions for the determination of the tensile properties of isotropic and orthotropic fibre-reinforced plastic composites, based upon the general principles given in ISO 527-1. NOTE 1 - Unidirectional reinforced materials are covered by ISO 527-5. The methods are used to investigate the tensile behaviour of the test specimens and for determining the tensile strength, tensile modulus, Poisson's ratios and other aspects of the tensile stress-strain relationship under the defined conditions. The test method is suitable for use with the following materials: - fibre-reinforced thermosetting and thermoplastic composites incorporating non-unidirectional reinforcements such as mats, woven fabrics, woven rovings, chopped strands, combinations of such reinforcements, hybrids, rovings, short or milled fibres or preimpregnated materials (prepregs); NOTE 2 - Injection moulded specimens are covered by ISO 527-2. - combinations of the above with unidirectional reinforcements and multidirectional reinforced materials constructed from unidirectional layers, provided such laminates are symmetrical; NOTE 3 - Materials with completely or mainly unidirectional reinforcements are covered by ISO 527-5. - finished products made from materials mentioned above. The reinforcement fibres covered include glass fibres, carbon fibres, aramid fibres and other similar fibres.

ČSN EN ISO 41015 (76 2107) This document gives guidance on the ways in which a facility management (FM) organization can influence organizational behaviours to achieve improved facility outcomes, including how it can engage, empower and influence users, service providers and other interested parties with one another for improved outcomes and user experience while interfacing with the built environment. Consequently, and simultaneously, these behaviours can be harnessed to contribute to the achievement of the demand organization's objectives and goals in an organizational sense, regardless of the type of organization or built environment involved. This is the fundamental link to the role of FM as defined in ISO 41001. This document is intended to build upon the requirements in ISO 41001, which adheres to the Plan-Do-Check-Act methodology. This document is applicable to organizations both large and small. NOTE 1 - For the purposes of this document, the term "organization" refers to the FM organization unless otherwise stated. NOTE 2 - The terms "facility management" and "facilities management" can be used interchangeably.

ČSN EN ISO 5167-1 Tento dokument definuje termíny a značky a zavedení obecných principů pro metody měření a výpočet průtoku tekutin proudících v potrubí pomocí snímačů diferenčního tlaku (clon, dýz, Venturiho trubic, kuželová měřidla a klínová měřidla) vložených do zcela zaplněného potrubí kruhového průřezu. Tento dokument také specifikuje obecné požadavky na metody měření, montáž a stanovení nejistoty měření průtoku. ISO 5167 (soubor) je použitelná pouze, když proudění v celém měřicím průřezu zůstává podzvukové a tam kde může být tekutina pokládána za jednofázovou. Není použitelná při měření pulzujícího průtoku.

ČSN EN 14870-4 This document specifies the technical delivery conditions for bends made by the cold bending process for bend with radii 5xOD or higher for use in pipeline transportation systems for the petroleum and natural gas industries as defined in ISO 13623. Short radius factory cold bends should not be used for pipeline. NOTE 1 - ISO 13623 is modified adopted as EN 14161 to exclude on-land supply systems used by the European gas supply industry from the input of gas into the on-land transmission network up to the inlet connection of gas appliances. This document also specifies the requirements for the manufacture of two product specification levels (PSLs) of cold bends corresponding to product specification levels given for pipe in ISO 3183. This document is applicable to cold bends made from seamless and welded pipe of unalloyed or low-alloy steels. NOTE 2 - These are typically C-Mn steels or low-alloy steels that are appropriate for the corresponding level and grade of line pipe in accordance with ISO 3183. This document is not applicable to the selection of the cold bend product specification level. It is the responsibility of the purchaser to specify the PSL, based upon the intended use and design requirements. NOTE 3 - See also ISO 3183:2012, Introduction. This document is not applicable to field cold bends and pipeline bends made by other manufacturing processes. On-land supply systems used by the European gas supply industry from the input of gas into the on-land transmission network up to the inlet connection of gas appliances are excluded from the scope of this document.
