Hi Zakaria,

You need to look under this chapter, chapter Off-white is all about Fusion of Plastics. Fusion not Welding is not the term used for joining of plastics.

Thanks.

Sorry for the typo, it should read as , Chapter QF. Joining of HDPE is covered under the requirements for polyethylene.

Thanks

Dear all,

I have just come across a fire on electro fusion fittings and wish to know how the fire is formed. Can you gentlemen shed some lights on it.
