APPENDICE C (informativa) RAPPORTO DI SALDATURA

La norma si applica al processo di saldatura ad elementi termici per contatto per la realizzazione di giunzioni testa a testa di tubi e/o raccordi in polietilene con spessore massimo di 65 mm per il trasporto di gas combustibili di acqua e di altri fluidi in pressione. Sono inoltre definit e le modalità per la preparazione e l'esecuzione delle saldature, i requisiti cui devono soddisfare le attrezzature impiegate, nonchè i tipi di controllo che devono essere realizzati per verificare la qualità del giunto.
