What is ISO 9170 ‑ 1 about?
ISO 9170 discusses terminal units for medical gas pipeline systems. ISO 9170 ‑ 1 is intended specially to ensure the gas-specific assembly, mechanical resistance, flow, leakage, and pressure drop of terminal units. To prevent their interchange between different gases and services.
ISO 9170-1 applies to terminal units intended for use in medical gas pipeline systems in accordance with ISO 7396-1 , used as pressure outlets on pressure regulators in accordance with ISO 10524-1 , used as pressure outlets on pressure regulators integrated with cylinder valves (VIPR) in accordance with ISO 10524-3 .
ISO 9170-1 applies to terminal units for use with the following gases for administration to patients or for medical uses (A) oxygen, nitrous oxide, medical air, carbon dioxide, oxygen/nitrous oxide mixture, helium/oxygen mixtures, oxygen 93, gases delivered to medical devices or intended for medical purposes, gas mixtures classified as a medical device, gases, and gas mixtures for medicinal use not specified above.
ISO 9170-1 also applies to terminal units for use with gases (B) is air for driving surgical tools and nitrogen for driving surgical tools.
ISO 9170-1 also applies to terminal units for use with vacuum systems.
Note 1: The requirements of ISO 9170 ‑ 1 can be used as guidelines for terminal units for other gases. These other gases will be considered for inclusion in this document when they come into general use.
Note 2: ISO 9170-1 does not specify the requirements for terminal units for anesthetic gas scavenging systems (AGSS), which are...
