22、ational standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. Inter

23、national organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the

24、 rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by

25、 at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 13982-2 was prepared by the European Committe

26、e for Standardization (CEN) Technical Committee CEN/TC 162, Protective clothing including hand and arm protection and lifejackets, in collaboration with Technical Committee ISO/TC 94, Personal safety Protective clothing and equipment, Subcommittee SC 13, Protective clothing, in accordance with the A

35、 and per exercise (average over all suits) 3.2.8Lmean total inward leakage (average over all test subjects, suits, exercises and sampling positions) 4 Principle A standard aerosol of sodium chloride particles is generated inside a test chamber in which a test subject, wearing the protective suit und

36、er test, carries out a predetermined sequence of test exercises. The inward leakage at each sampling position inside the suit is measured by means of flame photometry. The percentage inward leakage at each sampling position (Lijmn), the total inward leakage per suit (LS) and per test subject (LH), t

37、he total inward leakage per exercise (LE) and per sampling position (LP) and the mean total inward leakage ( L) are calculated. NOTE The test method is based on a testing principle similar to the inward leakage test principle for respiratory equipment, for type 1 and type 2 chemical protective cloth

38、ing and for protective clothing against radioactive contamination. The method provides a measure of the inward leakage into protective clothing by dry aerosol particles (generated from a sodium chloride solution) having a mass-median aerodynamic diameter of 0,6 m.5 Apparatus 5.1 Aerosol generator, f

39、lame photometer(s), one or two, and a test chamber, as described in EN 136. 5.2 Level treadmill, capable of operating at (5 r 0,5) km/h, which is installed inside the chamber. The test arrangement used for the determination of inward leakage is shown schematically in Figures 1 and 2. EN ISO 13982-2:

42、ide aerosol test agent, with a particle-size distribution, mean test-agent concentration and distribution inside the chamber as described in EN 136. 5.4 Adjustable pump and air lines, used for sampling air from the suit under test. This pump is adjusted to deliver a sampling flow rate from inside th

43、e suit in the range of (2 r 0,5) l/min. The flow shall be kept constant within r 0,2 l/min. Depending on the type of photometer, it may be necessary to dilute the sample air with clean air. There shall be no condensation in tubes during testing. Condensation in the tubes can be avoided by feeding dr

44、y, clean air directly into the tubes upstream of where condensation occurs (see Figure 2), by heating of the tubes or by any other suitable means. One should take the dilution into account when calculating the concentration at the sampling point. EN ISO 13982-2:200455.5 Sampling probes, four, constr

45、ucted as shown in Figure 3, one which shall be used to measure the challenge concentration and three, the concentration inside the suit. Each probe is fitted onto a length of suitable transparent plastic tube with an internal diameter of 4,0 mm. Dimensions in millimetres Figure 3 Sampling probe EN I

46、SO 13982-2:2004 6The three probes for measuring the concentration inside the suit shall be positioned close to the body of the test subject, at the following positions as shown in Figure 4: Key1 on the right chest 2 at the back of the waist 3 at knee height, lateral aProbe 2 is positioned on back. F

47、igure 4 Positions of the three sampling probes on body of test subject Especially in the case of two-piece suits and coveralls equipped with an elastic waistband or a belt worn over the suit, the positions of the sampling points should be carefully chosen. Sampling probes shall not be positioned dir

48、ectly onto the skin, but shall be fixed onto the underwear. The sampling lines to and from the sampling probes inside the suit shall be fixed close to the body of the test subject and shall pass through the material of the suit between 5 cm and 15 cm above one of the arm-cuffs in an airtight manner.

49、 The fixings of the sampling lines and the pass-through should have as little influence on the fit of the suit as possible and should not impair the movements of the test subject. To ensure that there is no additional inward leakage into the suit, due to under-pressure created by extraction of the sample air, clean air shall be fed back into the suit at the same rate as sample air is pumped out, i.e. at (2 r 0,5) l/min. This clean air shall be introduced through one of the other two sampling probes, according to the seque
