ČSN EN ISO/IEEE 11073-10471 Within the context of the ISO/IEEE 11073 family of standards for device communication, this standard esta-blishes a normative definition of the communication between independent living activity hubs 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 ambiguity in base frameworks in favor of interoperability. This standard defines a common core of communication functionality for independent living activity hubs. In this context, independent living activity hubs are defined as devices that communicate with simple situation monitors (binary sensors), normalize information received from the simple environmental monitors, and provide this normalized information to one or more managers. This information can be examined, for example, to determine when a person's activities/behaviors have deviated significantly from what is normal for them such that relevant parties can be notified. Independent living activity hubs will normalize information from the following simple situation monitors (binary sensors) for the initial release of the proposed standard: fall sensor, motion sensor, door sensor, bed/chair occupancy sensor, light switch sensor, smoke sensor, (ambient) temperature threshold sensor, personal emergency response system (PERS), and enuresis sensor (bed-wetting).

ČSN EN IEC 62065 ed. 3 This document specifies the minimum operational and performance requirements, test methods and required test results conforming to performance standards adopted by the IMO in resolution MSC.74(69) Annex 2 Recommendation on Performance Standards for Track Control Systems. In addition, it takes into account IMO resolution A.694(17) to which IEC 60945 is associated. It also takes into account IMO resolution MSC.302(87) on bridge alert management (BAM), to which IEC 62923-1 and IEC 62923-2 are associated.

ČSN EN 81-30 1.1 This document specifies the safety rules for the construction and installation of permanently installed service lifts, with traction, positive, or hydraulic drive, serving defined landing levels, having a carrier the interior of which is regarded as inaccessible to persons on account of its dimensions and means of construction, suspended by ropes or chains or jack and moving between rigid guide rails inclined not more than 15° to the vertical. This document covers service lifts with rated load not exceeding 300 kg and not intended to transport persons. 1.2 This document does not cover: a) service lifts with drives other than those stated in 1.1; b) services lifts having carrier with dimensions that exceed: 1) for floor area, 1,0 m2; 2) for depth, 1,0 m; 3) for height, 1,20 m. The height is not limited if the carrier comprises several permanent compartments, each of which satisfies the above dimensions. c) lifting appliances, such as paternosters, mines lifts, theatrical lifts, appliances with automatic caging, skips and hoists for building and public works sites, ships hoists, platforms for exploration or drilling at sea, construction and maintenance appliances; d) safety during operations of transport, erection, repairs and dismantling of service lifts; e) use of glass for the walls of the well, for the carrier and for the landing doors including their vision panels; f) hydraulic service lifts where the setting of the pressure relief valve exceeds 50 MPa; g) any form of radiation except EMC (see 4.10.1.1.3); h) installation in potentially explosive atmosphere, extreme climate conditions, seismic conditions, transporting dangerous goods, etc.; i) ambient temperature in the well and machinery space(s) lower than +5 °C and higher than +40 °C; j) health and safety of animals. However, this document can usefully be taken as a basis. Noise and vibrations are not dealt with in this document as they are not considered a significant nor relevant hazard for the actual type of the service lift. Fire propagation is not dealt with in this document. 1.3 The well is regarded as accessible if the opening giving access have clear dimensions of at least 0,40 m x 0,50 m, and: a) the horizontal depth of the well is greater than 1 m, or b) the area of the well is greater than 1 m2, or c) the maintenance is intended to be carried out from the carrier roof or pit regardless the well dimensions. 1.4 The machinery space is regarded as accessible if: a) the door(s)/trapdoor(s) giving access have clear dimensions of at least 0,60 m x 0,60 m, and b) the height of the passageway is at least 1,80 m. NOTE - A door about horizontal when closed is referred to as a trapdoor. 1.5 This document covers the safety requirements for service lifts with rated speeds up to 1 m/s. 1.6 This document is not applicable to service lifts which are installed before the date of its publication as EN.

ČSN EN ISO 9241-171 This document specifies requirements and gives guidelines for designing accessible software for people with the widest range of physical, sensory and cognitive abilities, including those who are temporarily or situationally disabled, and the elderly. It addresses software considerations for accessibility that complement general design for usability as addressed by parts of the ISO 9241 series, especially ISO 9241-11 and ISO 9241-210. This document is applicable to the accessibility of interactive systems. It addresses a wide range of software (e.g. home, mobile, office, web, learning support and library systems). It promotes the increased usability of systems for a wider range of users in the widest range of contexts of use. This document does not apply to the behaviour of, or requirements for, assistive technologies (including assistive software), but it does address the use of assistive technologies as an integrated component of interactive systems. It is intended for use by those responsible for the specification, design, development, evaluation and procurement of software platforms and software applications.
