CAN/CSA-Z9170-1-00 (R2010)

International Standard ISO 9170-1:1999 has been adopted with Canadian deviations as CSA Standard CAN/CSA-Z9170-1-00. 1 Scope This part of ISO 9170 specifies requirements for terminal units intended for use in medical gas pipeline systems in accordance with ISO 7396-1, for use with the following services: - oxygen; - nitrous oxide; - air for breathing; - carbon dioxide; - oxygen/nitrous oxide mixture [50 %/50 % (by volume)]; - air for driving surgical tools; - nitrogen for driving surgical tools; - vacuum. It is intended especially to ensure the gas-specific assembly of terminal units and to prevent their interchange between different gases. This part of ISO 9170 specifies requirements for terminal units for supply and disposal of nitrogen or air for driving surgical tools. This part of ISO 9170 specifies requirements for probes intended to be connected to the gas-specific connection point which is part of the terminal unit. This part of ISO 9170 does not specify the dimensions of probes and of the gas-specific connection points of the terminal units. This part of ISO 9170 does not specify the dimensions of NIST connectors, which are defined in ISO 5359. This part of ISO 9170 does not specify the requirements for terminal units for anaesthetic gas scavenging systems (AGSS), which are defined in ISO 9170-2. NOTE 1 The requirements of this part of ISO 9170 may be used as guidelines for terminal units for other medical gases. These medical gases will be considered for inclusion in this part of ISO 9170 when they come into general use. NOTE 2 Throughout this part of ISO 9170, clauses for which a rationale is provided in annex A are indicated by a boldface capital R.
