This European Standard shall be given the status of a n
22、ational standard, either by publication of an identical text or by endorsement, at the latest by June 2001, and conflicting national standards shall be withdrawn at the latest by September 2002. This European Standard has been prepared under a mandate given to CEN by the European Commission and the
23、European Free Trade Association, and supports essential requirements of EU Directive 89/106/EEC. For relationship with EU Directive(s), see informative Annex ZA, which is an integral part of this standard. This part of EN 12094 is one of a number of European Standards prepared by CEN/TC 191 covering
24、 components for gas extinguishing systems. They are included in a series of European Standards planned to cover: gas extinguishing systems (EN 12094); sprinkler systems (EN 12259 and EN 12845); powder systems (EN 12416); explosion protection systems (EN 26814); foam systems (EN 13565); hose systems
25、(EN 671); smoke and heat control systems (EN 12101); water spray systems. The following parts of this European Standard are planned: Part 1: Requirements and test methods for electrical automatic control and delay devices; Part 2: Requirements and test methods for non-electrical automatic control an
26、d delay devices; Part 3: Requirements and test methods for manual triggering and stop devices; Part 4: Requirements and test methods for high-pressure container valve assemblies and actuators; Part 5: Requirements and test methods for selector valves and actuators for CO2 systems; Part 6: Requiremen
27、ts and test methods for non-electrical disable devices for CO2 systems; Part 7: Requirements and test methods for nozzles for CO2 systems; Part 8: Requirements and test methods for flexible connectors for CO2 systems; Part 9: Requirements and test methods for special fire detectors; Part 10: Require

All pressure data in this European Standard ar
32、e given as gauge pressures in bar, unless otherwise stated. NOTE 1 bar = 105 N m-2 = 100 kPa. 1 Scope This European Standard specifies requirements and test methods for non-electrical disable devices that prevent during maintenance work in the protected room or object any kind of unintentional relea
33、se (automatic or manual) of CO2 installations or in multiple-zone systems of each individual flooding zone without disabling the fire detection and alarm functions. NOTE This standard can be used as guidance for testing electrical disable devices which work on different principles. 2 Normative refer
34、ences This European Standard incorporates by dated or undated references, provisions from other publications. These normative references are cited at the appropriate places in the text and the publications are listed hereafter. For dated references, subsequent amendments to or revisions of any of th
35、ese publications apply to this European Standard only when incorporated in it by amendment or revision. For undated references the latest edition of the publication referred to applies (including amendments). EN 12094-5:2000, Fixed firefighting systems Components for CO2 systems Part 5: Requirements

40、m-plated steel, etc.). All materials shall be resistant to media with which they come into contact. 4.1.2 Non-electrical disable devices shall be designed so that the function cannot be adversely affected by ageing or environmental influences. Non-metallic materials and elastomers shall be selected
41、to be stable and not alter their performance over the working life recommended by the manufacturer. 4.1.3 The non-electric disable device shall be mechanical or pneumatic. In multiple-zone installations a non-electric disable device shall be provided for each individual flooding zone. 4.1.4 The disabled and the operational states shall be clearly indicated. This indication shall be given at the non-electrical disable device itself. If an electrical control device is incorporated in the system the indication should be given at
