Pavojaus signalizavimo sistemos. Įsibrovimo ir apiplėšimo pavojaus signalizavimo sistemos. 3 dalis. Valdymo ir rodymo įranga

This document specifies the requirements, performance criteria and testing procedures for control and indicating equipment (CIE) intended for use in intrusion and hold-up alarm systems (I&HAS) installed in buildings. This document also applies to CIE to be used in IAS or HAS. The CIE can incorporate processing functions of other I&HAS components or its processing requirements can be distributed among such components. This document specifies the requirements for CIE installed in buildings using specific or non-specific wired interconnections or wire-free interconnections. These requirements also apply to basic DCC which can be installed outside of the supervised premises and mounted in indoor or outdoor environments. Where CIE shares means of detection, interconnection, control, communication, processing and/or power supplies with other applications, these requirements apply to I&HAS functions only. This document specifies performance requirements for CIE at each of the four security grades identified in EN 50131 1. Requirements are also specified for four environmental classes covering applications for indoor and outdoor locations. This document includes mandatory functions for all CIE for the appropriate security grade, as well as optional functions that can additionally be provided. This document does not cover requirements for compliance with EU regulatory Directives, such as the EMC Directive, Low Voltage Directive, etc. except in that it specifies the equipment operating conditions for EMC susceptibility testing as required by EN 50130 4. NOTE 1 In this document reference to the term “I&HAS” is used throughout, except where there is specific need to differentiate between the IAS and HAS portions of a system. The term is intended to include IAS and HAS when such systems are installed separately. NOTE 2 For products which integrate functions from, and which the manufacturer is claiming compliance to, several EN 50131 standards, the requirements of this document apply as well as any additional requirements from other relevant EN 50131 standards (e.g. a CIE with integral Warning Device is expected to meet the requirements of EN 50131 3 and EN 50131 4).

Sintezės įrenginiai. Tričio sintezės įrenginių ir branduolių sintezės energijos įrenginių reakcijos išlaikymo ir ventiliacijos sistemų projektavimui ir veikimui taikomi kriterijai (ISO 16646:2024)

This document specifies the applicable requirements related to the design and the operation of confinement and ventilation systems for fusion facilities for tritium fuels and tritium fuel handling facilities specific for fusion applications for peaceful purposes using high tritium inventories, as well as for their specialized buildings such as hot cells, examination laboratories, emergency management centres, radioactive waste treatment and storage facilities. In most countries, a tritium quantity is declared as high for tritium inventories higher than a range of 10 g to 100 g. In the tritium fusion facilities in the scope of this document, the tritium inventory is deemed to be higher than this range for the whole site. This document applies especially to confinement and ventilation systems that ensure the safety function of nuclear facilities involved in nuclear fusion with the goal to protect the workers, the public and the environment from the dissemination of radioactive contamination originating from the operation of these installations, and in particular from airborne tritium contamination with adequate confinement systems.

This document covers the functional recommendations for design, construction, testing, commissioning, operation, maintenance and abandonment of underground gas storage (UGS) facilities in oil and gas fields up to and including the wellhead. It specifies practices which are safe and environmentally acceptable. For necessary surface facilities for underground gas storage, EN 1918 5 applies. In this context “gas” refers to flammable gas: — which is in a gaseous state at a temperature of 15 °C and under a pressure of 0,1 MPa (the stored product is also named fluid); — which meets specific quality requirements in order to maintain underground storage integrity, performance, environmental compatibility and fulfils contractual requirements. This comprises: — gas not in liquid phase under subsurface conditions; — methane-rich gases; — natural gas; — biomethane; — synthetic methane; — hydrogen of various purities; — any mixtures of the gases above; — hydrocarbon gas in liquid phase under subsurface conditions such as; — ethylene; — liquified petroleum gas (LPG). NOTE 1 Correspondingly the EN 1918 series can be considered where applicable for underground storage of any other fluid e.g. helium, carbon dioxide, compressed air, rDME (renewable dimethyl ether) and hydrogen transport fluids (such as ammonia and LOHC). This document is not intended to be applied retrospectively to existing facilities. NOTE 2 Correspondingly this document can be considered for major conversions in case of significant change of gas composition.
