Alarm systems - Intrusion and hold-up systems - Part 3: Control and indicating equipment

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).

Electrical requirements for lifts, escalators and moving walks - Part 2: Electromagnetic compatibility with regard to immunity (ISO/DIS 8102-2:2025)

This document specifies the immunity performance criteria and test levels for apparatus used in lifts, escalators and moving walks which are intended to be permanently installed in buildings including the basic safety requirements in regard to their electromagnetic environment. These levels represent essential EMC requirements. This document refers to EM conditions as existing in residential, office and industrial buildings. This document addresses commonly known EMC related hazards and hazardous situations relevant to lifts, escalators and moving walks when they are used as intended and under the conditions foreseen by the lift installer or escalator and/or moving walk manufacturer. It is assumed that no ports connected to safety circuit only are rated at currents greater than 100 amps. It is assumed that mobile telephones and radio transmitters used at frequencies and power of that stated in Table 1 are not placed within 200 mm distance from safety circuit(s). However: — performance criteria and test levels for apparatus/assembly of apparatus used in general function circuits do not cover situations with an extremely low probability of occurrence; — this document does not apply to other apparatus already proven to be in conformity to the EMC national regulation, and not related to the safety of the lift, escalator or moving walk, such as lighting apparatus, communication apparatus, etc. This document does not apply to electromagnetic environments such as: — radio transmitter stations; — railways and metros; — heavy industrial plant; — electricity power stations; which need additional investigations. This document is not applicable to apparatus which were manufactured before the date of its publication.

Explosion isolation flap valves

This European Standard describes the general requirements for flap valves used for dust explosion isolation. An explosion isolation flap valve is a protective system, which prevents a dust explosion from propagating via connecting pipes or ducts into other parts of apparatus or plant areas. An explosion isolation flap valve can only stop the propagation of a dust explosion when it propagates against the direction of the normal process flow. It does not stop explosions running in the normal process flow direction. This European Standard specifies methods for evaluating the efficacy of explosion isolation flap valves. This European Standard is applicable only to the use of explosion isolation flap valves that are intended for avoiding explosion propagation from a vessel, into other parts of the installation via connecting pipes or ducts. The standard covers isolation of such vessels that are protected by explosion venting (including flameless venting), explosion suppression or explosion resistant design. NOTE 1 The standard assumes that the explosion starts in a vessel and not in ducting. Explosion isolation flap valves are not designed to prevent the transmission of fire or burning powder transported by the normal process flow. NOTE 2 It is necessary to take this into account in risk assessments. This European Standard is only applicable for dust explosions. This European Standard is not applicable for explosions of materials listed below, or for mixtures containing some of those materials: a) gases, vapours and hybrid mixtures; b) chemically unstable substances; c) explosive substances; d) pyrotechnic substances.

Oil and gas industries including lower carbon energy - Standard cost coding system (ISO/DIS 19008:2025)

ISO 19008:2016 describes the standard cost coding system (SCCS) that classifies costs and quantities related to exploration, development, operation and removal of oil and gas production and processing facilities and to the petroleum, petrochemical and natural gas industry. Upstream, midstream, downstream and petrochemical business categories are included. The SCCS for coding of costs is applicable to: - cost estimating; - actual cost monitoring and reporting; - collection of final quantities and cost data; - standardized exchange of cost data among organizations; - implementation in cost systems. ISO 19008:2016 is intended for users such as the following: a) owner/operator/company (individual or grouped entity that is entitled or contributes to operations in the exploitation of oil and gas fields); b) industry/trade associations; c) manufacturers/contractors; d) cost engineering service contractors, cost system providers, benchmarking providers, etc.; e) authorities/regulatory bodies. ISO 19008:2016 does not apply to the following: 1) cost classification relevant to cost accounting rules, specific contractual agreements, local requirements for cost reporting to national bodies, government rules and tax regulations, authorization for expenditure (AFE), billing purposes etc.; 2) specific project breakdown structures (e.g. work breakdown structures, contract breakdown structures, organizational breakdown structure) or asset breakdowns (e.g. TAG/system codes, area/module breakdown structure) which are and will remain unique. However, this International Standard can provide a basis for the establishment of such specific classification systems.
