Description

BS PD ISO/PAS 19891-1:2016 provides specifications in performance, gases to be measured, sensitivities,indications, alarm levels, protection against shock, temperature and water ingress, and testingrequirements of portable gas detectors used for atmosphere testing of enclosed spaces on board shipsprior to entry into those spaces.

This part of ISO/PAS 19891 specifies suitable portable gas detectors for compliance with SOLASregulation XI-1/7 “Atmosphere testing instrument for enclosed spaces”, and can be used for decidingwhether portable gas detectors available on the market are suitable for compliance with these SOLASrequirements.

NOTE 1 SOLAS regulation XI-1/7 requires appropriate portable atmosphere testing instrument or instrumentsto be carried on board ships by 1 July 2016. The SOLAS regulation states that, as a minimum, the appropriateportable atmosphere testing instrument or instruments be capable of measuring concentrations of oxygen,flammable gases or vapours, hydrogen sulphide and carbon monoxide prior to entry into enclosed spaces.

For the purpose of measurement of concentrations of flammable gases or vapours, this part ofISO/PAS 19891 specifies the flammable gas as either “methane” or “propane and butane”, and requiresclear marking of types of flammable gases which can be measured by the portable gas detectors. For anoptimal use of ISO/PAS 19891, it should be noted that flammable vapours/gases which are not marked,cannot be measured, or detected by the portable gas detector.

NOTE 2 Iso-butane can be used as calibration gas of portable gas detectors measuring propane and butane.This part of ISO/PAS 19891 does not give any indication of the toxicity of the flammable gases.
