Electromagnetic compatibility - Electrical apparatus for the detection and measurement of combustible gases, toxic gases or oxygen
This European Standard specifies requirements for the electromagnetic compatibility (EMC) for electrical apparatus for the detection and measurement of combustible gases, toxic gases or oxygen which are subject to the performance standards for gas detection apparatus, for example EN 45544 (all parts), EN 50104, EN 50194 (all parts), EN 50291, EN 50379 (all parts), EN 50543, EN 50545, EN 60079-29-1 or EN 60079-29-4. NOTE For the purpose of this standard the word ‘toxic’ covers ‘very toxic’, ‘toxic’, ‘harmful’, ‘corrosive‘, ‘irritating‘, ‘sensitising‘, ‘carcinogenic‘, ‘mutagenic‘ and ‘teratogenic‘. This European Standard applies to apparatus intended for use in residential, commercial and light-industrial environments as well as to apparatus intended for use in industrial environments. The apparatus may be AC-, DC- or battery powered. This European Standard is also applicable to apparatus which is intended for use in hazardous areas which may contain explosive or potentially explosive atmospheres. It covers only normal operation and does not cover safety requirements related to EMC phenomena. This standard is a product standard which is based on the product family standard EN 61326-1. This product standard takes precedence over the product family standard and over generic standards. This standard applies to electrical apparatus for the detection and measurement of combustible gases, toxic gases or oxygen that include functions specified by the manufacturer as being safety functions and can include functions specified as not being safety functions. All performance standards for the detection and measurement of combustible gases, toxic gases or oxygen include the minimum requirements for functional safety specified in EN 50271. There are also gas detectors and gas detection systems which are intended to be used with safety integrity levels SIL 1 to SIL 3 according to EN 50402 and EN 61508. For functional safety in industrial applications, this standard has taken into account those aspects of EN 61326–3–2 relating to the measuring and warning function of the apparatus defined as safety function. Apparatus of type 1 where the manufacturer claims a safety integrity level should be considered as type 2 apparatus with regard to immunity requirements. This standard specifies requirements for immunity tests in relation to continuous and transient, conducted and radiated disturbances, including electrostatic discharges, and also for emission tests. The test requirements are specified for each port considered. Apparatus falling within the scope of this European Standard is classified as follows by the following types. Type 1: apparatus intended for use in residential, commercial and light-industrial environments, as described in EN 61000-6-1 and EN 61000-6-3. Type 2: apparatus intended for use in industrial environments, as described in EN 61000-6-2 and EN 61000-6-4. This European Standard does not apply to any of the following: apparatus intended for the detection of dusts or mists in air; scientific or laboratory based apparatus used only for analysis or measurement; apparatus used exclusively for process measurement purposes; apparatus for medical purposes; apparatus used for breath alcohol measurement apparatus intended for the direct measurement of automotive exhaust gases.

Elektromagnetna združljivost - Električne naprave za odkrivanje in merjenje vnetljivih in strupenih plinov ali kisika
Ta evropski standard določa zahteve za elektromagnetno združljivost (EMC) za električne naprave za odkrivanje in merjenje vnetljivih in strupenih plinov ali kisika, ki so predmet standardov za delovanje naprav za odkrivanje plinov, kot so standardi EN 45544 (vsi deli), EN 50104, EN 50194 (vsi deli), EN 50291 (vsi deli), EN 50379 (vsi deli), EN 50543, EN 50545-1, EN 60079-29-1 ali EN 60079-29-4.
OPOMBA V tem standardu beseda »strupeno« zajema »zelo strupeno«, »strupeno«, »škodljivo«, »korozivno«, »ki draži«,
»ki povzroča preobčutljivost«, »rakotvorno«, »mutageno« in »teratogeno«.
Ta evropski standard velja za naprave, ki so namenjene uporabi v stanovanjskih, poslovnih in manj zahtevnih industrijskih okoljih ter industrijskih okoljih. Naprave se lahko napajajo prek izmeničnega ali enosmernega toka ali baterij.
Ta evropski standard velja tudi za naprave, ki so namenjene uporabi na nevarnih območjih v eksplozivnih ali potencialno eksplozivnih atmosferah. Določa le normalno delovanje in
ne zajema varnostnih zahtev, povezanih z elektromagnetno združljivostjo.
To je standard za proizvode, ki temelji na standardu skupine proizvodov EN 61326-1. Ta
standard za proizvode ima prednost pred standardom skupine proizvodov in splošnimi standardi.
Ta standard velja za električne naprave za odkrivanje in merjenje vnetljivih
in strupenih plinov ali kisika s funkcijami, ki ji je proizvajalec določil kot varnostne funkcije, in funkcijami, določenimi kot funkcije, ki niso povezane z varnostjo.
Vsi standardi, povezani z delovanjem električnih naprav za odkrivanje in merjenje vnetljivih in strupenih plinov ali
kisika, vključujejo minimalne zahteve za funkcionalno varnost, kot je določeno v standardu EN 50271. Obstajajo tudi detektorji plina in sistemi za odkrivanje plina, namenjeni uporabi s stopnjami varnostne celovitosti sistema od SIL 1 do SIL 3 v skladu s standardoma EN 50402 in EN 61508 (vsi deli). Ta standard pri funkcionalni varnosti pri industrijskih aplikacijah upošteva tiste vidike standarda EN 61326–3–2, ki so povezani z merilno in opozorilno funkcijo naprave, ki je določena kot varnostna funkcija.
Ta standard določa zahteve za preskuse odpornosti v povezavi s trajnimi in prehodnimi motnjami ter motnjami sevanja, vključno z elektrostatičnimi razelektritvami, in tudi za preskuse emisij. Preskusne zahteve so določene za vsaka obravnavana vrata.
Naprave, ki jih zajema ta evropski standard, so razvrščene v naslednje spodaj navedene tipe:
– Tip 1: naprave, ki so namenjene uporabi v stanovanjskih, poslovnih in manj zahtevnih industrijskih okoljih, kot
je opisano v standardih EN 61000-6-1 in EN 61000-6-3.
– Tip 2: naprave, ki so namenjene uporabi v industrijskih okoljih, kot je opisano v standardih EN 61000-6-2 in
EN 61000-6-4.
Naprava tipa 1, za katero proizvajalec navaja stopnjo varnostne celovitosti kot za napravo tipa 2, v povezavi z zahtevami glede odpornosti.
Ta evropski standard se ne uporablja za:
– naprave za odkrivanje prahu ali meglic v zraku;
– znanstvene ali laboratorijske naprave, ki se uporabljajo samo za analize ali meritve;
– naprave, ki se uporabljajo samo za namene merilnega postopka;
– naprave za medicinske namene;
– naprave za merjenje alkohola v izdihanem zraku;
– naprave, namenjene za neposredne meritve avtomobilskih izpušnih plinov.

does not cover safety requirements related to EMC phenomena.
This standard is a product standard which is based on the product family standard EN 61326-1. This
product standard takes precedence over the product family standard and over generic standards.
This standard applies to electrical apparatus for the detection and measurement of combustible gases,
toxic gases or oxygen that include functions specified by the manufacturer as being safety functions and

All performance standards for the detection and measurement of combustible gases, toxic gases or
oxygen include the minimum requirements for functional safety specified in EN 50271. There are also gas
detectors and gas detection systems which are intended to be used with safety integrity levels SIL 1 to

– Type 2: apparatus intended for use in industrial environments, as described in EN 61000-6-2 and
EN 61000-6-4.
Apparatus of type 1 where the manufacturer claims a safety integrity level should be considered as type 2
