female part of a terminal unit which is either integral or attached to the base block by a type-specific interface, and which contains the type-specific connection point

3.2

AGSS terminal unit

inlet assembly in an AGSS at which the operator makes connections and disconnections

3.3

AGSS terminal unit base block

part of an AGSS terminal unit which is attached to the pipeline disposal system

3.4

AGSS type 1 terminal unit

connection point between the receiving system and the disposal system at which an operator makes connections and disconnections

3.5

AGSS type 1H terminal units

AGSS type 1 terminal unit to be used in high-flow disposal systems

3.6

AGSS type 1L terminal units

AGSS type 1 terminal unit to be used in low-flow disposal systems

3.7

AGSS type 2 terminal unit

connection point between the power device or the disposal hose and the remainder of the disposal system at which an operator makes connections and disconnections

3.8

AGSS type-specific

having characteristics which prevent interchangeability and thereby allow assignment to one AGSS type only

3.9

AGSS type-specific connection point

part of the AGSS socket which is the receptor for an AGSS type-specific probe

3.10

air compressor system

source of supply with compressor(s) designed to provide medical air and/or air for driving surgical tools and/or air for AGSS

Note 1 to entry: Different names or symbols are used for air for driving surgical tools, such as: instrument air, surgical air, air motor, air - 700 and air - 800.

3.11

anaesthetic gas scavenging system

AGSS

complete system which is connected to the exhaust port(s) of a breathing system or other equipment for the purpose of conveying expired and/or excess anaesthetic gases and vapours to an appropriate point of discharge

Note 1 to entry: Functionally, an AGSS comprises three different parts: a transfer system, a receiving system and a disposal system. These three functionally discrete parts can be either separate or sequentially combined in part or in total. In addition, one or more parts of an AGSS can be combined with a breathing system or other equipment (e.g. an anaesthetic ventilator) to include the transfer system, or transfer and receiving systems.

3.12

commissioning

proof of function to verify that the agreed specification is met and is accepted by the user or his representative

3.13

disposal hose

part of an AGSS which transfers expired and/or excess anaesthetic gases and vapours from the power device to the probe of an AGSS type 2 terminal unit

3.14

disposal system

means by which the expired and/or excess anaesthetic gases and vapours are conveyed from the receiving system to an appropriate point of discharge

Note 1 to entry: A point of discharge can be, for example, the exterior of a building or a non-recirculating extract ventilation system.

3.15

diversity factor

factor which represents the maximum proportion of terminal units in a defined clinical area which will be used at the same time, at flowrates defined in agreement with the management of the healthcare facility

3.16

high-flow disposal system

disposal system which is intended to operate with a high-flow transfer and receiving system complying with ISO 8835-3

3.17

high-flow transfer and receiving system

transfer and receiving system complying with ISO 8835-3 which connects through an AGSS type 1H terminal unit as specified in ISO 9170-2 to a high-flow disposal system complying with this part of ISO 7396

3.18

low-flow disposal system

disposal system which is intended to operate with a low-flow transfer and receiving system complying with ISO 8835-3

3.19

low-flow transfer and receiving system

transfer and receiving system complying with ISO 8835-3 which connects through an AGSS type 1L terminal unit as specified in ISO 9170-2 to a low-flow disposal system complying with this part of ISO 7396

3.20

manufacturer

natural or legal person with responsibility for the design, manufacture, packaging and labelling of a device before it is placed on the market under his own name, regardless of whether these operations are carried out by that person himself or on his behalf by a third party

3.21

maximum operating pressure

maximum pressure at which a terminal unit is designed to operate

Note 1 to entry: Operating pressure for a type 1 terminal unit is negative and for a type 2 terminal unit it is positive.

3.22

maximum test pressure

maximum pressure to which a terminal unit is designed to be subjected during pipeline pressure testing

3.23

non-return valve

valve which permits flow in one direction only

3.24

power device

part of an AGS disposal system that provides flow and pressure for scavenging

3.25

probe

non-interchangeable male component designed for acceptance by, and retention in, a socket

3.26

quick connector

pair of type-specific components which can be easily and rapidly joined together by a single action of one or both hands without the use of tools

3.27

receiving hose

part of an AGSS which transfers expired and/or excess anaesthetic gases and vapours from the receiving system to the disposal system

3.28

receiving system

part of an AGSS which provides an interface between the transfer system and the disposal system

3.29

shut-off valve

valve which prevents flow in both directions when closed

3.30

single fault condition

condition in which a single means for protection against a safety hazard in equipment is defective or a single external abnormal condition is present

3.31

system design flow

flow calculated from the maximum flow requirement of the healthcare facility and corrected by the diversity factor(s)

3.32

transfer system

part of an AGSS which transfers expired and/or excess anaesthetic gases from the exhaust port of the breathing system or other equipment to the receiving system

3.33
