9.15 ASTM F 1208 – 89 (2005) Disclosures
Based on the following disclosures, the A5/A3 meets ASTM Standard Specification F1208 for
Anesthesia Breathing Systems.
9.15.1 Leakage of Breathing System
9.15.2 Resistance of Breathing Systems
The typical pressure drops due to inspiratory and expiratory gas flow in the breathing system at
reference flows of 0.5 and 1.0 L/s are:
• Manual, Inspiratory flow: flow rate = 0.5 L/s @ 0.59 kPa resistance
• Manual, Inspiratory flow: flow rate = 1.0 L/s @ 0.24 kPa resistance
• Manual, Expiratory flow: flow rate = 0.5 L/s @ 0.21 kPa resistance
• Manual, Expiratory flow: flow rate = 1.0 L/s @ 0.43 kPa resistance
• Auto, Inspiratory flow: flow rate = 0.5 L/s @ 0.23 kPa resistance
• Auto, Inspiratory flow: flow rate = 1.0 L/s @ 0.58 kPa resistance
• Auto, Expiratory flow: flow rate = 0.5 L/s @ 0.44 kPa resistance
• Auto, Expiratory flow: flow rate = 1.0 L/s @ 0.20 kPa resistance

Absorber Capacity
CO
2
absorber capacity is 1 Pre-Pak or 1500 ml.
Grounding
Impedance:
Complies with the requirements of clause 8.6 in IEC 60601-1.
The impedance between the protective earth terminal and any accessible
metal part (e.g., screw and equipotential stud) that is protectively earthed
does not exceed 0.1 ohm.
Protective Grounding: Complies with the requirements of clause 8.6 in IEC 60601-1.
The protective earth terminal is not used for the mechanical connection
between different parts of the equipment or the fixing of any component not
related to protective earthing or functional earthing.
