Foreword

All technical content in this section is mandatory. GB 15322 "combustible gas detector" is divided into the following parts. --- Part 1. Point-type combustible gas detectors for industrial and commercial use; --- Part 2. Household flammable gas detectors; --- Part 3. Portable combustible gas detectors for industrial and commercial use; --- Part 4. Linear and flammable gas detectors for industrial and commercial use. This part is the third part of GB 15322. This part is drafted in accordance with the rules given in GB/T 1.1-2009. This part replaces GB 15322.3-2003 "Combustible gas detectors Part 3. Portable with a measuring range of 0~100% LEL Combustible gas detectors and GB 15322.6-2003 "Combustible gas detectors - Part 6. Portable flammable gas detector". Compared with GB 15322.3-2003 and GB 15322.6-2003, the main technical changes in this section are as follows. --- Combine the contents of GB 15322.3-2003 and GB 15322.6-2003 into one part; --- According to the measurement range, the detectors are divided into three types. detectors with measuring range between 3%LEL and 100% LEL, measuring range Detectors below 3% LEL and detectors measuring over 100% LEL. Divide the detector according to the way of working There are two types. continuous working detectors and single measuring detectors (see Chapter 3, GB 15322.3-2003 and Chapter 4 of GB 15322.6-2003); --- Increased the requirements for the detector concentration display function (see 4.3.1.5); ---Modified the test conditions of the high temperature (running) test and the low temperature (running) test, and alarmed the detector under various test conditions Action value requirements (see Chapter 4, GB 15322.3-2003 and Chapter 5 of GB 15322.6-2003); --- Increased anti-poisoning performance test (see 4.3.12); --- Increased low concentration operation test (see 4.3.14). This part is proposed and managed by the Emergency Management Department of the People's Republic of China. This section drafted by. Shenyang Fire Research Institute of Emergency Management Department, Chengdu Anchuang Electronics Co., Ltd., Hanwei Technology Group Co., Ltd., Fuyang Huaxin Electronic Instrument Co., Ltd., Jinan Benan Technology Development Co., Ltd., Yingjisen Safety Fire System (Shanghai) Co., Ltd.

1 Scope

This part of GB 15322 specifies the classification, requirements, tests, inspection rules and regulations for portable flammable gas detectors for industrial and commercial use. Sign. This section applies to industrial and commercial applications for the detection of hydrocarbons, ethers, esters, alcohols, carbon monoxide, hydrogen and other combustibles. Portable flammable gas detector (hereinafter referred to as "detector") for gas and vapor. Special properties used in industrial and commercial locations The detectors may also be implemented in addition to the special requirements specified by the relevant standards.

3 classification

3.1 According to the measurement range is divided into. a) detectors measuring between 3% LEL and 100% LEL; b) detectors measuring below 3% LEL (including detectors for detecting carbon monoxide); c) Detectors with a measurement range of 100% LEL or more. Note. The lower explosive limit (LEL) is the lowest explosive concentration of flammable gas or vapor in the air. 3.2 Divided into working methods. a) continuous working type detectors; b) Single measurement type detector.

4 requirements

4.1 General The detector shall meet the relevant requirements of Chapter 4 and be tested in accordance with the provisions of Chapter 5 to confirm the detector's requirements for Chapter 4.
