Pavojaus signalizavimo sistemos. Įspėjimo apie pavojų sistemos. 1 dalis. Gyvenamuosiuose pastatuose naudojamos įspėjimo apie pavojų sistemos. Sistemai keliami reikalavimai

This document applies to the planning, installation, operation, and maintenance of hazard warning systems (HWS) for use in residential buildings, flats, and rooms with flat-like use. It also specifies basic requirements and provisions for reliable interconnection of safety and security technology with smart home systems or active assisted living (AAL) systems and applications. Furthermore, it describes basic requirements for devices and systems or references to respective standards and specifications. This document does not override or in any way limit existing European standards. Hazard warning systems are used for early warning of persons to avoid or reduce personal injury and damage to property, which can result from intrusion, hold-up, fire, dangerous gases, and water ingress as well as technical defects of building services. HWS can also be used in residential properties in the event of duress/harassment and, for communication with persons in emergency situations who are present in the property covered by the HWS or to initiate controls in building services because of the aforementioned events. HWS can be designed in compliance with this standard as a self-contained system, or as HWS with connection of Smart Home components, or as a HWS that is a Smart Home system with integrated security applications. For the purposes of this document, the term “smart home” includes all networked systems and or web-based technical processes or IoT devices that are used in residential properties. This includes also, for example, remotely controllable devices such as cameras, entertainment electronics, household appliances, heating, air conditioning, ventilation (HVAC), electrical control components, door/gate/window openings and others. For the purposes of this document, AAL systems are assistance systems that support everyday life and are usually used in combination with services to provide needs-based support in the home environment for people with special needs. In most cases, AAL systems are web- or IoT-based. AAL systems and components are tailored to the individual needs of their users and their living environment and are networked with the building technology and security technology (in this case the HWS) for safety reasons to provide the user with the best possible support to make sure they react appropriately and in time to the situation in the event of an emergency. The task of AAL systems often includes recognizing critical health conditions of their users and initiating appropriate measures. For the purposes of this document, the term networking also means any integration of systems into the HWS and in many cases the connection to smart devices (e.g. smartphone, tablet, PC) via the Internet in conjunction with a specific application software (app). This standard can also be applied when systems are connected to the HWS and themselves use a connection to the Internet to outsource functional intelligence and utilize opportunities to automate processes across application areas, which can be either local, remote or a combination. Any notification or change in status of the HWS or its components can optionally be sent to other persons present in the building and/or to other locations/systems (e.g. emergency call centres [ERC]).

Mažieji laivai. Stabilumo ir plūdrumo vertinimas ir skirstymas į kategorijas. 2 dalis. Burlaiviai (ISO/DIS 12217-2:2026)

This document specifies methods for evaluating the stability and buoyancy of intact (i.e. undamaged) boats. The flotation characteristics of boats susceptible to swamping are also encompassed. The evaluation of stability and buoyancy properties using this document will enable the boat to be assigned to a design category (A, B, C or D) appropriate to its design and maximum load. This document is principally applicable to boats propelled primarily by sail (even if fitted with an auxiliary engine) of 6 m up to and including 24 m hull length. However, it can also be applied to boats less than 6 m if they are habitable multihulls or can be applied if they do not attain the desired design category specified in ISO 12217‑3 and they are decked and have quick-draining recesses which comply with ISO 11812. In relation to habitable multihulls, this document includes assessment of susceptibility to inversion, definition of viable means of escape and requirements for inverted flotation. This document excludes: — inflatable and rigid-inflatable boats covered by the ISO 6185 series, except for references made in the ISO 6185 series to specific clauses of the ISO 12217 series; — gondolas and pedalos; — surfboards including sailing surfboards; and — hydrofoils and foil stabilized boats when not operating in the displacement mode. NOTE Displacement mode means that the boat is only supported by hydrostatic forces. It does not include or evaluate the effects on stability of towing, fishing, dredging or lifting operations, which need to be separately considered if appropriate.

This document specifies terminology, principles and a process for the clinical evaluation of medical devices. The process described in this document aims to assist manufacturers of medical devices to estimate the clinical risks associated with a medical device and evaluate the acceptability of those risks in the light of the clinical benefits achieved when the device is used as intended. The requirements of this document are applicable throughout the life cycle of a medical device. The process described in this document applies to the assessment of risks and benefits from clinical data obtained from the use of medical devices in humans. This document specifies general requirements intended to — verify the safety of medical devices when used in accordance with their instructions for use; — verify that the clinical performance or effectiveness of a medical device meet the claims of the manufacturer in relation to its intended use; — verify that there is sufficient clinical evidence to demonstrate the achievement of a positive benefit/risk balance when a medical device is used in the intended patient population in accordance with its intended use; — ensure the scientific conduct of a clinical evaluation and the credibility of conclusions drawn on the safety and performance of a medical device; — define the responsibilities of the manufacturer and those conducting or contributing to a clinical evaluation; and — assist manufacturers, clinicians, regulatory authorities and other bodies involved in the conformity assessment of medical devices. Note 1 This standard can be used for regulatory purposes. Note 2 This document does not apply to in vitro diagnostic medical devices. However, there may be situations, dependent on the device and national or regional requirements, where sections and/or requirements of this document might be applicable.

This document specifies requirements and test methods for pipes and fittings which are part of piping systems for the renovation of underground non-pressure drainage and sewerage networks. It is applicable to pipes, fittings and assemblies, made from thermoplastic composite materials, as manufactured and as installed. It is not applicable to the existing pipeline. It is applicable to technique families for renovation: — lining with spirally-wound (SWO) pipes; — lining with a rigidly anchored plastic inner layer (RAPL). and intended to be used at an operating temperature of 20 °C as the reference temperature. In the case of lining with SWO pipes, where the pipes, are formed on site, to a fixed or variable diameter, by spirally winding and jointing a pre-manufactured profiled plastics strip, this document applies to, strips made of unplasticized poly(vinyl chloride) (PVC U), or of polyethylene (PE), with or without steel stiffening elements, and installed with or without integral locking mechanism. In the case of lining with RAPL, where a single rigid annulus of structural cementitious grout is formed behind a plastics inner layer serving as permanent formwork anchored to the grout. This document applies to integrally joined profiled plastics strips of PVC-U or PE or studded sheets of PE, and grout systems with or without steel reinforcement. It does not apply to the structural design of the lining system. NOTE Systems with multiple annuli are available, but these are controlled by patent rights and not covered by this document.
