前言这是CAN/CSA-Z10524-4《医用气体用压力调节器-第4部分:低压调节器》的第一版，采用了同名的ISO（国际标准化组织）标准10524-4（第一版，2008-06-01），但有加拿大的偏差。范围1。1 ISO 10524的本部分适用于1.2中列出的低压调节器类型，用于治疗、管理、诊断评估和护理患者时使用以下医用气体:-氧气；-一氧化二氮；-医用空气氦；-二氧化碳；-氙；-上述气体的特定混合物； -用于驱动手术工具的空气用于驱动手术工具的氮气富氧空气。1.2 ISO 10524本部分涵盖的低压调节器类型如下:a）拟连接至符合ISO 7396-1的医用气体管道系统终端装置的低压调节器；b） 低压调节器，带有整体式流量计量装置，拟连接至符合ISO 7396-1的医用气体管道系统的终端装置；c） 低压调节器拟连接至连接至符合ISO 10524-1或ISO 10524的压力调节器的终端装置- 3.d） 操作员可调低压调节器，用于驱动手术工具，该工具是符合ISO 7396-1的医用气体管道系统的组成部分。1.3 ISO 10524的本部分不适用于麻醉和呼吸设备中集成的低压调节器。

PrefaceThis is the first edition of CAN/CSA-Z10524-4, Pressure regulators for use with medical gases - Part 4: Low-pressure regulators, which is an adoption, with Canadian deviations, of the identically titled ISO (International Organization for Standardization) Standard 10524-4 (first edition, 2008-06-01).Scope1.1 This part of ISO 10524 applies to the types of low-pressure regulators listed in 1.2 and intended to be used with the following medical gases in the treatment, management, diagnostic evaluation and care of patients: - oxygen; - nitrous oxide; - medical air; - helium; - carbon dioxide; - xenon; - specified mixtures of the gases listed above; - air for driving surgical tools; - nitrogen for driving surgical tools; - oxygen-enriched air. 1.2 The types of low-pressure regulators covered by this part of ISO 10524 are as follows: a) low-pressure regulators intended to be connected to terminal units of medical gas pipeline systems complying with ISO 7396-1; b) low-pressure regulators with integral flow-metering devices intended to be connected to terminal units of medical gas pipeline systems complying with ISO 7396-1; c) low-pressure regulators intended to be connected to terminal units attached to pressure regulators complying with ISO 10524-1 or ISO 10524-3; d) operator-adjustable low-pressure regulators for air or nitrogen for driving surgical tools that are an integral part of a medical gas pipeline system complying with ISO 7396-1. 1.3 This part of ISO 10524 does not apply to low-pressure regulators integrated within anaesthetic and respiratory equipment.
