Appendix A
(Normative)
Test method for inward leakage of chemical protective clothing against
solid particulates
A.1 Scope
This Appendix specifies the test method for the inward leakage of protective clothing.
A.2 Principle
The aerosol generator generates standard NaCl particle aerosols and passes into the test room to maintain a relatively stable state. The measured object wears the measured protective clothing and performs the test action in the test room according to a predetermined plan. The particle detector measures the concentration of NaCl particle aerosol in the measured protective clothing at a fixed sampling point; evaluate the overall protective performance of the protective clothing against particles by the following indicators:
-- the single inward leakage Lijmn at each sampling point;
-- the total inward leakage LS of each piece of measured protective clothing; -- the total inward leakage LH of each measured object;
-- the total inward leakage LE of each test action;
-- the total inward leakage LP at each sampling point;
-- the average total inward leakage .
A.3 Test device

10 -- dry, clean air.
Note: For certain types of particle detectors, due to the limitation of the detection device range, it?€?s necessary to use clean air carrier gas to dilute the sample air. During the test, in order to avoid condensation in the pipeline, send dry and clean air to the air pipeline (5) behind the sampling probe; or heat the pipeline or use other suitable methods to prevent condensation. When calculating the concentration at the sampling point, the dilution of the carrier gas shall be considered.

additional dry and clean air at the test tube)
A.3.1 NaCl particle aerosol generator
1 unit; the generated gas volume is not less than 100 L/min; the NaCl particle aerosol concentration is (10 ?? 1) mg/m3; the concentration change in the effective space of the test room is ??? ??10%. The aerodynamic particle size distribution of particles shall be (0.02 ~ 2) ??m; the mass median diameter is about 0.6 ??m.
A.3.2 Particle detector
2 detectors, which are, respectively, used to detect the aerosol concentration of NaCl particles in the test room and the measured protective clothing. The dynamic range is (0.001 ~ 200) mg/m3; the accuracy is ??1%; the response time of the detector is ???500 ms.
A.3.3 Horizontal pedal transmission test bench

2 sets, which are, respectively, used to collect and detect the NaCl particle aerosol in the test room and the measured protective clothing. The flow range is (0.05 ~ 4) L/min; the flow fluctuation is < ??0.2 L/min. It can be guaranteed that the sampling probe can sample at a flow rate of (2 ?? 0.5) L/min inside the measured protective clothing.
In order to ensure that the decompression that is generated by sampling in the measured protective clothing does not cause additional inward leakage, it shall be delivered into the measured protective clothing at the rate of (2 ?? 0.5) L/min while sampling. Clean air can be input through one of the other two sampling probes in the sampling intermittent state in the sampling order that is given in Table A.1.
A.3.5 Sampling probe
4 sampling probes, as shown in Figure A.3. One of them shall be used to detect the concentration of NaCl particle aerosol in the test room environment; the other three are used to measure the concentration of NaCl particle aerosol inside the measured protective clothing. The sampling probe is connected to a transparent plastic tube, of which the inner diameter is 4.0 mm and the length is suitable.
