11、02 Gas respirators 1 Scope This Japanese Industrial Standard specifies gas respirators for inhaling the air cleaned by removing poisonous gases or vapors (hereafter referred to as “poi- sonous gas”) or particulate substance mixed with poisonous gas in work area or other places (hereafter referred to
12、 as “respirators”). 2 Normative references The following standards contain provisions which, through reference in this Standard, constitute provisions of this Standard. The most recent editions of the standards (including amendments) indicated below shall be applied. Glossary of terms for respirator

14、tion resis- tance The difference, between the pressure inside of the respirator when wearing it and breathing or connecting a breathing simulator and operating it, and the atmospheric air, creates the waveform as shown in Fig. 1. The maximum value on the minus side of every wave is called the inhala
15、tion resistance peak value and the maximum value on the plus side is called the exhalation resistance peak value. + I Exhalation resistance /- peak value Time Difference of pressure between inside and outside of respirator -I Inhalation resistance peak value Fig. 1 Inhalation resistance peak value a

17、re classified into the types given in Table 1. into those with filter and those without filter. The absorption cartridges are as given in Table 2 and, moreover, they are divided The symbols for each class of absorption cartridge with filter are as given in Table 3. Remarks : The absorption cartridge
18、s with filter are intended as well to collect and remove particulate materials, and there are two types, built-in filter type and separable filter type.

45、n is not felt when wearing. The wearer himself can confirm anytime the fitness of the face to the face piece by closing the inhalation inlet or exhalation outlet. When the absorption cartridge, head harness, inhalation valve, exhalation valve, etc. are exchanged, the performance and wearing property
46、 of the respirator are not impaired. When using harmful material, the construction is ensured not to give hindrance to the human body by means, for example, of coating and filtration.
