Električne naprave za odkrivanje in merjenje strupenih in gorljivih plinov na avtomobilskih parkiriščih in v predorih - 1. del: Splošne tehnične zahteve in preskusne metode za zaznavanje in merjenje ogljikovega monoksida in dušikovih oksidov - Dopolnilo A1
Ta mednarodni standard velja za naprave za odkrivanje in/ali merjenje ogljikovega monoksida (CO), dušikovega monoksida (NO) in dušikovega dioksida (NO2), ki se uporabljajo za nadzor prezračevalnega sistema in/ali za prikaz, alarm ali drug signal, ki opozarja na nevarnost strupov. Ti trije plini se za ta evropski standard na splošno imenujejo »ciljni plini«. Nacionalne in lokalne zahteve morda ne zahtevajo odkrivanja NO ali NO2, lahko pa zahtevajo odkrivanje drugih plinov ali hlapov.
Ta evropski standard vključuje zahteve za oddaljene plinske senzorje (RGS), ki se uporabljajo na avtomobilskih parkiriščih in v predorih, in zahteve za nadzorno enoto (CU), ki se uporablja na avtomobilskih parkiriščih.
Ta evropski standard določa splošne zahteve za gradnjo in preskušanje ter opisuje preskusne metode, ki veljajo za fiksne naprave za odkrivanje in/ali merjenje koncentracij ciljnih plinov na avtomobilskih parkiriščih in v predorih. Ta evropski standard se lahko uporabi tudi pri podobnih aplikacijah, kjer koncentracija ciljnih plinov lahko privede do tveganja zdravja, na primer na območjih za nakladanje tovornjakov in podzemnih avtobusnih postajah.
Ta evropski standard velja tudi pri izjavah proizvajalca naprave o boljši zmogljivosti, ki presega minimalne zahteve.
Ta evropski standard velja za naprave, vključno s sistemom za vzorčenje, če je primerno.
Ta evropski standard ne določa zahtev za naprave, nameščene na nevarnih območjih.
Ta evropski standard ne velja za aplikacije, ki jih že zajemajo naslednji standardi:
– gospodinjstva, ki jih zajema EN 50291-1,
– čolni, plovila, prikolice ali avtodomi, ki jih zajema EN 50291-2,
– atmosfere na delovnem mestu, ki jih zajema serija EN 45544,
– emisije grelnikov, ki jih zajema serija EN 50379,
– emisije motornih vozil, ki jih zajema ISO/PAS 3930,
– nadzor ravni vnetljivih plinov LEL, ki ga zajema EN 60079-29-1.
Ta evropski standard ne velja za naslednje aplikacije in tehnologije:
– omejeni prostori, nedostopni za ljudi,
– laboratorijska ali analitska oprema,
– naprave za nadzor industrijskih procesov,
– prenosne in premične naprave,
– odkrivanje plinov na odprtih poteh,
– gradnja predorov,
– nadzor delcev in prahu,
– nadzor vnetljivih plinov,
– nadzor CO za odkrivanje požarov.

Overview
EN 50545-1:2011/A1:2016 is a CENELEC amendment to the European standard for electrical apparatus used to detect and measure toxic and combustible gases in car parks and road tunnels. The standard (Part 1) defines general performance requirements and test methods specifically for carbon monoxide (CO) and nitrogen oxides (NO/NO2) measurement. The A1 amendment clarifies and renumbers test clauses and specifically revises the NO/NO2 air‑velocity test to ensure it can be practically performed for both diffusion and aspirated gas detection apparatus.
Key topics and requirements
- Scope and intent: Test and performance requirements for gas detectors used in enclosed road and parking environments where vehicle exhaust creates CO and NOx hazards.
- Performance criteria: General requirements for reliable detection and measurement of CO and nitrogen oxides (NO/NO2), including apparatus behaviour under expected environmental conditions (original EN 50545-1).
- Test methods: Laboratory and field test procedures for both diffusion and aspirated detectors, including separate testing of:
- Remote gas sampling systems (RGS)
- Control units (CU)
- Complete apparatus assemblies
- Air velocity considerations: Amendment A1 deletes the previous subclause dealing with air velocity for diffusion apparatus and adjusts clause numbering to make the NO/NO2 air‑velocity test practicable and executable by test laboratories.
- Document consistency changes: Clause reference updates throughout clauses 5.2–5.4 and 6.x to reflect the restructured test sequence and to remove ambiguous or non‑performable test instructions.
Practical applications
- Manufacturers of CO and NOx gas detectors use EN 50545-1:2011/A1:2016 to design, validate and declare performance of detectors intended for car parks and tunnels.
- Test laboratories and conformity assessors implement the revised test methods (including the updated air‑velocity test) to certify equipment to European national standards.
- System integrators, ventilation engineers and facility managers apply the standard’s requirements when specifying detection systems for tunnel ventilation control and parking garage safety systems.
- Regulatory bodies and procurement teams reference the standard when preparing tender specifications and safety compliance checks for transport infrastructure.
Related standards and committees
- Part of the EN 50545 family addressing gas detection for road environments; prepared by CLC/TC 216 ("Gas detectors").
- For comprehensive compliance, users should consider other EN 50545 parts and national implementations that apply to installation, calibration and maintenance.
