I. Determinazione e metodi di prova per le parti conduttive esterne collegate all'apparecchio <\/p>\n\n\n\n

Parti conduttrici esterne che sono attaccate o fanno parte di un involucro non metallico e hanno una resistenza di terra superiore a 1 G\u03a9 misurata a (500 \u00b1 25) V c.c., e parti suscettibili di cariche statiche che possono diventare fonti di accensione, come targhette, ecc. <\/p>\n\n\n\n

La capacit\u00e0 di tali componenti deve essere determinata in conformit\u00e0 ai metodi di prova specificati nelle relative clausole. <\/p>\n\n\n\n

II. Requisiti per altri dispositivi ad eccezione dei dispositivi portatili o individuali <\/p>\n\n\n\n

Se la capacit\u00e0 misurata di una parte conduttiva supera i valori indicati nella Tabella 11, l'apparecchiatura deve essere contrassegnata con il simbolo \u201cX\u201d appropriato e le condizioni speciali di utilizzo devono specificare il valore della capacit\u00e0 misurata in modo che l'utente possa determinare l'applicabilit\u00e0 in applicazioni specifiche. Non \u00e8 necessario sottoporre a prova le parti conduttive esterne situate in una posizione tale che non si prevede che scarichino verso oggetti messi a terra. <\/p>\n\n\n\n

Nota: \u2460 In genere si ritiene che la capacit\u00e0 dei dispositivi di fissaggio metallici non messi a terra, come le viti di copertura, non superi i 3 pF. \u2461 Per le apparecchiature di Classe III destinate all'uso in tubazioni in cui \u00e8 possibile la presenza di polvere in rapido movimento, si sta valutando un limite di capacit\u00e0 inferiore.<\/p>","protected":false},"excerpt":{"rendered":"
