Vazduh na radnom mestu – Električni aparati koji se koriste za direktnu detekciju i direktno merenje koncentracije toksičnih gasova i pare – Deo 4: Uputstvo za izbor, instalisanje, korišćenje i održavanje

English title

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

Serbian scope

Ovim evropskim standardom se daju smernice za propratna objašnjenja, kao i za izbor, instaliranje, korišćenje i održavanje električnih aparata koji se koriste za direktnu detekciju i direktno merenje koncentracije toksičnih gasova i para u vazduhu na radnom mestu. Primarna namena ovih aparata je merenje koncentracije toksičnih gasova ili pare radi obezbeđivanja merenja izloženosti i/ili detekcije i upozorenja na njegovo prisustvo.Ovaj evropski standard je primenjiv na aparate čija je primarna namena da obezbedi signalizaciju, alarm i/ili bilo koju drugu izlaznu funkciju koja daje upozorenje o prisustvu toksičnih gasova ili pare u atmosferi i koji sami automatski generišu električne signale onda kada je gas prisutan.

English scope

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.
