Workplace atmospheres - Electrical apparatus used for the direct detection and direct concentration measurement of toxic gases and vapours - Part 4: Guide for selection, installation, use and maintenance
This European Standard gives guidance on the selection, installation, use and maintenance of electrical apparatus used for the direct detection and direct concentration measurement of toxic gases and vapours in workplace atmospheres. The primary purpose of such apparatus is to measure the concentration of a toxic gas or vapour in order to provide an exposure measurement and/or detection and warning of its presence. This European Standard is applicable to apparatus whose primary purpose is to provide an indication, alarm and/or other output function to give a warning of the presence of a toxic gas or vapour in the atmosphere and in some cases to initiate automatic or manual protective actions. It is applicable to apparatus in which the sensor automatically generates an electrical signal when gas is present. This European Standard is not applicable, but may provide useful information, for apparatus — used for the measurement of oxygen, — used only in laboratories for analysis or measurement, — used only for process measurement purposes, — used in car parks or tunnels (fixed apparatus only), — used in the domestic environment, — used in environmental air pollution monitoring, — used for the measurement of combustible gases and vapours related to the risk of explosion. It also does not apply to open-path (line of sight) area monitors. For apparatus used for sensing the presence of multiple gases, this European Standard applies only to the detection of toxic gas or vapour.

Zrak na delovnem mestu - Električne naprave za neposredno odkrivanje in neposredno merjenje koncentracije strupenih plinov in hlapov - 4. del: Vodilo za izbiro, vgraditev, uporabo in vzdrževanje
Ta evropski standard vključuje navodila za izbiro, namestitev, uporabo in vzdrževanje električnih
naprav, ki se uporabljajo za neposredno odkrivanje in neposredno merjenje koncentracije strupenih plinov in hlapov v ozračju na delovnem mestu. Primarni namen takšnih naprav je izmeriti koncentracijo strupenih plinov ali hlapov, ki omogoča merjenje izpostavljenosti in/ali zaznavanje ter opozarjanje na njihovo prisotnost.
Ta evropski standard se uporablja za naprave, katerih primarni namen je izdati opozorilo, alarm in/ali drugo izhodno funkcijo, s katero se opozori na prisotnost strupenih plinov ali hlapov v ozračju in v nekaterih primerih tudi sproži samodejne ali ročne zaščitne ukrepe. Uporablja se za aparate, v katerih senzor ob prisotnosti plina samodejno ustvari električni signal.
Čeprav se ta evropski standard ne uporablja zanje, je vseeno lahko vir uporabnih informacij za naprave,
– ki se uporabljajo za merjenje kisika,
– ki se uporabljajo le v laboratorijih za analize ali merjenje,
– ki se uporabljajo samo za namene merilnega postopka,
– ki se uporabljajo v voznih parkih ali predorih (le nepremične naprave),
– ki se uporabljajo v domačem okolju,
– ki se uporabljajo pri nadzoru onesnaženja zraka v okolju,
– ki se uporabljajo za merjenje plinov in hlapov pri izgorevanju v zvezi z nevarnostjo eksplozije.
Prav tako se ne uporablja za senzorje z odprto merilno potjo (linija pogleda).
Pri napravah, ki se uporabljajo za zaznavanje prisotnosti več plinov, se ta evropski standard uporablja le za zaznavanje strupenih plinov ali hlapov.

Figure 2 — Apparatus scale showing ranges, indications and limits 6.3.2 Apparatus conforming to EN 45544-2 EN 45544-2 details the performance requirements outlined in EN 482 specifically for electrical apparatus used for the direct detection and direct concentration measurement of toxic gases and vapours intended for exposure measurement. This includes requirements for the lower and upper limits of measurement and requirements for the uncertainty of measurement expressed as the relative expanded uncertainty. The lower limit of measurement is the smallest value of the measured quantity within the measuring range. It is derived from the zero uncertainty of the apparatus resulting from the variation of measured values in clean air, see Figure 3. Values below the lower limit of measurement are therefore not necessarily an indication that gas is present. The calculation of the lower limit of measurement is described in EN 45544-1.
