3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
3.1 lower explosive limit; LEL
Under standard atmospheric conditions, the minimum concentration of a combustible gas or vapour in air that will explode.
3.2 monitoring condition
The state of a detector after it has been powered on and is operating normally, without any combustible gas alarm, fault, self test, sensor end of life, etc., occurring.
3.3 industrial detectors
Detectors installed in industrial sites where various types of combustible gases and volatile combustible liquids are stored, transported, used or produced, for the purpose of real time monitoring of the concentration of combustible gases and vapours in the area.
3.4 commercial detectors
Detectors installed in various public and commercial premises other than residential environments such as houses and apartments, for the purpose of real time monitoring of the concentration of methane, propane and carbon monoxide in the area.
3.5 industrial and commercial detectors
Detectors that have both the functions of industrial detectors and commercial detectors, meeting the performance requirements for both industrial and commercial premises.
3.6 pipeline and well detectors
Detectors installed in closed environments such as underground pipelines and shafts where there is a risk of combustible gas accumulation, for the purpose of periodic monitoring of the concentration of combustible gases in the area.
3.7 system based detectors
Industrial or commercial detectors that have their own operating status indication function and, after establishing communication with control and indicating equipment such as a combustible gas alarm control unit via wired or wireless communication means, can realise the functions of a combustible gas detection and alarm system.
3.8 stand alone detectors
Industrial or commercial detectors that can be used independently at the installation site, having functions such as operating status indication, measured concentration display, audible signal output, historical event record storage, and control activation of field actuators.

a)System based detectors;
b) Stand alone detectors.
4.4 Industrial detectors are classified according to the measurement range as:
a)Detectors with a measurement range from 3% LEL to 100% LEL;
b) Detectors with a measurement range below 3% LEL (including detectors for carbon monoxide).
4.5 Industrial detectors are classified according to the use environment as:
a)Detectors for indoor use;
b) Detectors for outdoor use.
5 Requirements
