Introduction

GB/T 40531 will standardize the product performance and inspection methods of marine gas detectors for the manufacture and use of marine gas detectors. And inspection provides technical basis. In view of the fact that the international standard ISO 19891 adopted by GB/T 40531 only released Part 1, GB/T 40531 currently only has. ---Part 1.Portable gas detectors in enclosed spaces. Can be used for portable gas detector detection to prove that portable gas Whether the body detector meets the requirements of the SOLAS Convention. The other parts of GB/T 40531 will be formulated in time according to the release status of other parts of ISO 19891 and will be rolled out one after another. Ship and Marine Technology Ship Gas Detector Specification Part 1.Portable gas detectors in enclosed spaces

1 Scope

This document specifies the performance, gas measurement, sensitivity, result display, and performance of portable gas detectors used before entering enclosed spaces on ships Alarm level, impact resistance, temperature and humidity protection, and measurement requirements, etc. This document can be used for portable gas detector testing to prove compliance with SOLAS Convention XI-1/7 "Gas Detection in Enclosed Spaces" "Detector" requirements can also be used to determine whether portable gas detectors on the market meet the requirements of the SOLAS Convention. Note 1.From July 1,.2016, SOLAS Convention XI-1/7 stipulates portable gas testing equipment and shipboard equipment. The SOLAS Convention requires that The portable gas testing equipment on board in front of the shelter can at least test the concentration of oxygen, combustible gas or steam, hydrogen sulfide, and carbon monoxide. In order to measure the concentration of combustible gas or vapor, the combustible gas mentioned in this document is methane or a mixture of propane and butane, and it is required to be portable The type of combustible gas is clearly marked on the integrated gas detector. Unmarked combustible gases cannot be detected and measured by portable gas detectors. Note 2.The portable gas detector can use isobutane as the calibration gas when measuring propane and butane gas. This document does not apply to the toxicity test of combustible gas.
