This document applies to the basic safety and essential performance of a critical care ventilator in combination with its accessories, hereafter referred to as ME equipment: - intended for use in an environment that provides specialized care for patients whose conditions can be life-threatening and who can require comprehensive care and constant monitoring in a professional healthcare facility; NOTE 2 - For the purposes of this document, such an environment is referred to as a critical care environment. Ventilators for this environment are considered life-sustaining. NOTE 3 - For the purposes of this document, such a critical care ventilator can provide ventilation during transport within a professional healthcare facility (i.e. be a transit-operable ventilator). NOTE 4 - A critical care ventilator intended for use in transport within a professional healthcare facility is not considered as an emergency medical services environment ventilator. - intended to be operated by a healthcare professional operator; and - intended for those patients who need differing levels of support from artificial ventilation including for ventilator-dependent patients.

This document is also applicable to those accessories intended by their manufacturer to be connected to a ventilator breathing system, or to a ventilator, where the characteristics of those accessories can affect the basic safety or essential performance of the ventilator. NOTE 5 - If a clause or subclause is specifically intended to be applicable to ME equipment only, or to ME systems only, the title and content of that clause or subclause will say so. If that is not the case, the clause or subclause applies both to ME equipment and to ME systems, as relevant. Hazards inherent in the intended physiological function of ME equipment or ME systems within the scope of this document are not covered by specific requirements in this document except in IEC 60601-1:2005+AMD1:2012+AMD2:2020, 7.2.13 and 8.4.1.

ČSN EN ISO 19901-3 This document provides requirements, guidance and information for the design and fabrication of topsides structure for offshore structures, including in-service, pre-service and post-service conditions. The actions on topsides structure and the action effects in structural components are derived from this document, where necessary in combination with other International Standards in the ISO 19901 series (e.g. ISO 19901-1 for wind actions - see 7.6.2, ISO 19901-2 for seismic actions - see 7.7) and ISO 19902 for fatigue design (see 6.7). This document is applicable to the following: - topsides of fixed offshore structures; - discrete structural units placed on the hull structures of floating offshore structures and mobile offshore units; - topsides of arctic offshore structures, excluding winterization (see ISO 19906). If any part of the topsides structure forms part of the primary structure of the overall structural system which resists global platform actions, the requirements of this document are supplemented with applicable requirements in ISO 19902, ISO 19903, ISO 19904-1, ISO 19905-1, ISO 19905-3 and ISO 19906. For those parts of floating offshore structures and mobile offshore units that are chosen to be governed by the rules of a recognized classification society, the corresponding class rules supersede the associated requirements of this document. This document also addresses prevention, control and assessment of fire, explosions and other accidental events. The fire and explosion provisions of this document can be applied to those parts of the hulls of floating structures and mobile offshore units that contain hydrocarbon processing, piping or storage. NOTE - Requirements for structural integrity management are presented in ISO 19901-9. This document applies to structural components including the following: - primary and secondary structure in decks, module support frames and modules; - flare structures; - crane pedestal and other crane support arrangements; - helicopter landing decks (helidecks); - permanent bridges between separate offshore structures; - masts, towers and booms on offshore structures. This document provides requirements for selecting and using a national building standard with a correspondence factor for determining the resistance of rolled and welded non-circular prismatic components and their connections.

ČSN EN 1991-2 ed. 3 (1) This document defines imposed loads (models and representative values) associated with road traffic, pedestrian actions and rail traffic which include, when relevant, dynamic effects and centrifugal, braking and acceleration actions and actions for accidental design situations. (2) The imposed loads defined in this document are applicable for the design of new bridges, including decks, piers, abutments and associated walls (e.g. upstand walls, wing walls and flank walls) and their foundations. These imposed loads can also be used for the design of other structures subject to traffic loads (e.g. road tunnel floor slabs, noise barriers and their foundations). Where appropriate, the loads can also be considered as a basis for assessment or modification of existing structures in combination with complementary conditions if necessary. (3) The load models and values given in this document are also applicable for the design of retai-ning walls adjacent to roads and railway lines and the design of earthworks subject to road or rail traffic actions. This document also provides applicability conditions for specific load models. (4) This document is intended to be used with EN 1990, the other parts of the EN 1991 series and the EN 1992 series to EN 1999 series for the design of structures.
