    Déantar an uirlis PN-PTI iomlán a thástáil le haghaidh a líneachta le cáithníní poileasraithe de chineál súiche atá cobhsaí go teirmeach agus a bhfuil GMD 70 ± 10 nm agus GSD níos ísle nó cothrom le 1,6 acu;

    The whole PN-PTI instrument is tested for its linearity with thermally stable, polydisperse soot-like particles with GMD 70 ± 10 nm and GSD lower or equal to 1,6;

    Déantar fíorú ina dhiaidh sin ag 3 thiúchan dhifriúla le cáithníní poileasraithe a bhfuil dáileadh méide aonmhóid, GMD 70 ± 20 nm agus GSD níos ísle nó cothrom le 2,1 acu.

    Subsequent verification is a test performed at 3 different concentrations with polydisperse particles with monomodal size distribution, GMD 70 ± 20 nm and GSD lower or equal to 2,1.

    Áirítear san fhíorú tosaigh tástáil líneachta le cáithníní poileasraithe a bhfuil dáileadh méide aonmhóid, GMD 70 ± 20 nm agus GSD níos ísle nó cothrom le 2,1 acu.

    The initial verification includes a linearity test with polydisperse particles with monomodal size distribution, GMD 70 ± 20 nm and GSD lower or equal to 2,1.

    Ceanglaítear dáileadh mhéid na gcáithníní a thairgeann an gineadóir cáithníní iniompartha chun GMD agus GSD a shainmhínítear i Roinn 6.2 le haghaidh ar a laghad 3 h ar an iomlán in imeacht 3 lá dhifriúla faoi na coinníollacha céanna is a úsáidfear é sa réimse.

    The particle size distribution produced by the portable particle generator is required to fulfil the GMD and GSD defined in Section 6.2 for a total of at least 3 h spread over 3 different days under the same conditions that will be used in the field.

    Cinntear an éifeachtúlacht áirimh le cáithníní aoneasraithe de mhéideanna a shainmhínítear sa Roinn seo nó le cáithníní poileasraithe a bhfuil meántrastomhas geoiméadrach (“GMD”) acu a shainmhínítear sa Roinn seo agus diall caighdeánach geoiméadrach (“GSD”) níos ísle nó cothrom le 1,6;

    The counting efficiency is determined with monodisperse particles with sizes defined in this Section or with polydisperse particles with geometric mean diameter (‘GMD’) defined in this Section and geometric standard deviation (‘GSD’) lower or equal to 1,6;
