Propriet\u00e0 del rischio di incendio precoce<\/em> - Test di infiammabilit\u00e0 del vostro prodotto per Codice del test: T18B<\/strong><\/em><\/p>\n

AS\/NZS 1530.3-1999........<\/strong>Determinazione simultanea di ignizione, propagazione della fiamma, rilascio di calore e rilascio di fumo (propriet\u00e0 di rischio di incendio precoce).<\/strong><\/em><\/span><\/p>\n

Un campione montato verticalmente viene portato in una posizione di 850 mm di fronte a un radiatore. A intervalli di 30 secondi il provino viene avvicinato alla fonte di calore in una serie di passi. Se dopo 12,5 minuti non si \u00e8 verificata l'accensione, il campione rimane a 175 mm dal pannello per altri 7,5 minuti (per un tempo di esposizione totale massimo di 20 minuti) o fino a quando non si verifica l'accensione, a seconda della condizione pi\u00f9 prossima.<\/p>\n

Durante l'esposizione, una piccola fiamma pilota a gas viene tenuta a 15 mm di fronte al campione. Questa fiamma pilota accende i gas combustibili emessi, ma non la superficie del campione. Quando si verifica l'accensione, il movimento in avanti viene interrotto. Il tempo medio di accensione di tutti i campioni, sottratto da 20, determina l'INDICE DI IGNITABILIT\u00c0.<\/p>\n

Durante l'esposizione si utilizza un radiometro per misurare il calore irradiato dal campione. Si osserva un aumento costante man mano che il campione si avvicina alla fonte di calore, seguito da un rapido aumento al momento dell'accensione.<\/p>\n

L'output del radiometro registrato viene successivamente analizzato per determinare:<\/p>\n

a)<\/em><\/strong>          Il tasso di aumento dopo l'accensione, misurando il tempo impiegato dalla radiazione per aumentare di 1,4 kW\/m2 rispetto al valore precedente l'accensione; e<\/em><\/p>\n

b)<\/em><\/strong>          L'area sotto la curva di radiazione per i due minuti successivi all'accensione, che viene convertita in un valore di calore evoluto in kJ\/m2.<\/em><\/p>\n

I risultati di tutti i campioni testati vengono calcolati come media e i valori di INDICE DI SPREAD OF FLAME e INDICE DI CALORE EVOLUTO <\/em>sono determinati dalle tabelle riportate nella norma.<\/p>\n

\"\"<\/p>\n

Sono necessarie tre prove supplementari se i risultati dei primi sei campioni non rientrano nei limiti di variabilit\u00e0 previsti.<\/p>\n
