标准摘要
[中文适用范围]: 1.1 本文件规定了流量控制装置的要求,用户可将这些装置直接通过探头或专用气体连接器连接,或间接通过符合 ISO 5359 的低压软管组件连接到:a) 符合 ISO 9170-1 的医用气体管道系统的终端单元;b) 符合 ISO 10524-1:2018 的调节器的压力出口;或 c) 符合 ISO 10524-3 的阀门集成压力调节器 (VIPR) 的压力出口(见 5.2 气体入口)。1.2 本文件适用于以下类型的流量控制装置 (FCD):a) 流量计;b) 流量计 FCD;和 c) 固定孔口 FCD。注意:被归类为医用电气设备的流量控制装置可能需遵守 IEC 60601-1 的额外要求。1.3 本文件适用于以下气体的流量控制装置:— 氧气; — 氧气 93%; — 一氧化二氮; — 医用空气; — 二氧化碳; — 氧气/一氧化二氮混合物 50/50(% 体积分数); — 富氧空气; — 氦气; — 氙气;和 — 上述气体的指定混合物。注:也可提供用于其他气体的流量控制装置。1.4 本文件不适用于以下流量控制装置:a) 用于驱动手术器械的气体;b) 调节器的整体组成部分(参见 ISO 10524-1:2018);或 1c) 带集成压力调节器 (VIPR) 的阀门的整体组成部分(参见 ISO 10524-3)。 [外文原描述]: This document specifies requirements for flow control devices that can be connected by the user either directly, by means of a probe or a gas-specific connector, or indirectly by means of a low-pressure hose assembly conforming with ISO 5359 to: a) a terminal unit conforming with ISO 9170 - 1 of a medical gas pipeline system conforming with ISO 7396 - 1 : 2016 ; b) the pressure outlet of a regulator conforming with ISO 10524 - 1 : 2018 ; or c) to the pressure outlet of a valve integrated pressure regulator (VIPR) conforming with ISO 10524 - 3 (see 5.2 gas inlets). This document applies to the following types of flow control devices (FCDs): a) flowmeters ; b) flowgauge FCDs ; and c) fixed orifice FCDs . NOTE Flow control devices that are classed as medical electrical equipment can be subject to additional requirements of IEC 60601 - 1 . This document applies to flow control devices for the following gases: — oxygen; — oxygen 93 %; — nitrous oxide; — medical air; — carbon dioxide; — oxygen/nitrous oxide mixture 50/50 (% volume fraction); — oxygen-enriched air; — helium; — xenon; and — specified mixtures of the gases listed above. NOTE Flow control devices can be available for other gases. This document does not apply to flow control devices that are: a) for use with gases for driving surgical tools; b) an integral part of a regulator (see ISO 10524 - 1 : 2018 ); or c) an integral part of a valve with integrated pressure regulator (VIPR) (see ISO 10524 - 3 ).
