introduction
This outline is a revision of JJF 1363-2012.The revision of this outline refers to JJG695-2019 "Hydrogen Sulfide
Detector", GB 12358-2006 "General technical requirements for ambient gas detection and alarm in workplaces",
GB/T 25923-2010 "Online Gas Analyzer Technical Conditions", GB/T 11606-2007 "Analytical Instrument
Environmental Test Methods" and other technical regulations. Compared with JJF 1363-2012, in addition to editorial changes, the main technical
The technical requirements have changed as follows.
---Modified the scope of application (see 1);
---Added key parts and materials to the overview (see 3);
---Modified the measurement performance requirements, and listed the measurement performance requirements of the analyzer and the detection alarm (see Table 2);
--- Modify the appearance to appearance and structure (see 6.1);
---Delete alarm setting errors, and add alarm function check for instruments with alarm function (see 6.2);
---The relative expanded uncertainty and inclusion factor of the gas reference material are different from the original relative expanded uncertainty
If greater than 2%, k=3 is modified to the relative expanded uncertainty not greater than 2%, k=2.When using a gas dilution device,
The relative expanded uncertainty of the diluted standard gas should meet the above requirements (see 9.1.1.3);
---Specify the types of alarms applicable to vibration test and drop test (see Table 5);
---Modified the technical indicators of the indication error in the high temperature test, low temperature test and constant damp heat test. (see
6.5.1, 6.5.2, 6.5.3);
---Modified the type evaluation outline list, and divided the evaluation methods of type evaluation items into observation item evaluation and test
Evaluation of test items to make the description clearer (see Table 5);
---Changed the technical information that the applicant should submit, and stipulated the number of prototypes and the method of use
(See 8);
---Adjusted the indication error test method and drift data processing (see 9.1.1 and 9.1.4.5);
---Modified the display error in climate environment adaptability, mechanical environment adaptability, electromagnetic environment (immunity)
Detection method (see 9.2.5.4, 9.2.6.4, 9.2.7.4, 9.2.8.4, 9.2.9.4, 9.2.10.4,
9.2.11.4, 9.2.12.4);
--- Added a table of measuring instruments used in test items (see Table 6);
---Delete the requirements for battery performance in the adaptability of the power environment;
---Deleted accuracy (maximum allowable error) requirements, installation mark requirements, other requirements, insulation resistance,
Insulation strength, high temperature storage test, low temperature storage test;
---Changed the original record format of the type evaluation (see Appendix A).
The previous versions of this outline are as follows.

3 overview
The hydrogen sulfide gas detection alarm is mainly used to detect the concentration of hydrogen sulfide gas in the workplace environment. With alarm
For functional instruments, when the display value is greater than the alarm setting value, there should be sound, light or vibration alarm. The instrument is mainly composed of a test sheet
Unit, signal processing unit, alarm unit and display unit. The detection principle is mainly electrochemical method. By sample
The method is divided into diffusion type and pump suction type. According to the way of use, it is divided into portable and fixed. It can be divided into discontinuous
Sex measurement and continuity measurement.
The hydrogen sulfide gas analyzer is mainly used to measure the concentration of hydrogen sulfide gas in the production process and workplace environment. instrument
The device is mainly composed of a gas circuit unit, a detection unit, a signal processing unit and a display unit. The detection principle is mainly spectroscopy
Law etc. According to the sampling method, it is divided into positive pressure conveying type and pumping type. According to the working mode, it can be divided into discontinuous measurement and continuity
measuring.
The key components are generally gas sensors, circuit boards, etc., as shown in Table 1.
