 *If the fittings are made of alloy and not pure copper, then a 10 FH flux is required.

Cu tubes in Natural Gas installations should be joined to fittings (according to standards EN 1254-1 & EN 1254-5) or components, using filler alloys with high melting point. The acceptable alloys have been standardized (see for example standard EN 1044 replaced by EN ISO 17672).
