Toxic gas monitors and monitoring systems, and their dedicated detecting components as follows: detectors; sensor devices; replaceable sensor cartridges; and dedicated software for such equipment;
(a) designed for continuous operation and usable for the detection of chemical warfare agents, or AG-controlled precursors with a ‘minimum detection limit’ of less than 0.3 mg/m3; or
(b) designed for the detection of cholinesterase-inhibiting activity.
Technical note 1: The `minimum detection limit` of toxic gas monitors or monitoring systems is the lowest detectable concentration of the analyte required to produce a signal greater than three times the standard deviation of the toxic gas monitor’s or monitoring system’s signal when measuring a blank sample.
In the case of toxic gas monitors or monitoring systems having a deadband or programmed zero suppression, the ‘minimum detection limit’ is the lowest detectable concentration required to produce a reading.
