La presente Norma internazionale fa parte della serie EN 61249 e fornisce i requisiti delle proprietà delle lastre stratificate rinforzate in fibra di vetro di tipo E poliammidico, epossidico brominato modificato o non, di infiammabilità definita (prova di combustione verticale), ricoperti di rame.
Lo spessore dei fogli (lastre) va da 0,05 mm a 3,2 mm.
Il grado di infiammabilità si ottiene usando ritardanti del fuoco bromurati come parte integrante della struttura epossidica polimerizzata se presente.
La temperatura di transizione del tessuto di vetro ha il valore minimo di 190° C.
Per alcuni requisiti di proprietà possono aversi diverse classi di prestazioni. In questi casi la classe va precisata nell'ordine di acquisto, altrimenti viene assegnata la classe di default.
Questa Norma viene pubblicata dal CEI nella sola lingua inglese in quanto particolarmente mirata a settori specialistici.
La presente Norma recepisce il testo originale inglese della Pubblicazione IEC e pertanto consta delle sole pagine dispari.
