How long to keep PWHT Records? 1

[DefenderJ]

I need to set a time limit on keeping PWHT records.
These are for modifications and repair work of low carbon steel piping in an alumina refinery.
I am looking for some idea of what other people do so I can be realisitic (rather than keep everything)
I am thinking 5 years - does that sound reasonable?

Thanks in advance.
John

5 years is in line with ISO 29001 used by the oil & gas industry

Thanks for that Steve. Nice and concise!
Good to know there is a standard to refer to.
Cheers, John
