NEN-ISO 19891-1 provides specifications on performance, gases to be measured, sensitivities, indications, alarm levels, protection against shock, temperature and water ingress, and testing requirements of portable gas detectors used for atmosphere testing of enclosed spaces onboard ships prior to entry into those spaces. This document specifies suitable portable gas detectors for compliance with SOLAS regulation XI-1/7 “Atmosphere testing instrument for enclosed spaces”, and may be used for deciding whether portable gas detectors available on the market are suitable for compliance with these SOLAS requirements. For the purpose of measurement of concentrations of flammable gases or vapours, this document specifies the flammable gas as either “methane” or “propane and butane”, and requires clear marking of types of flammable gases which can be measured by the portable gas detectors. Flammable vapours/gases which are not marked cannot be measured or detected by the portable gas detector. This document does not give any indication of toxicity of the flammable gases.
