What is the BLUE flex used for. Is that designed for outdoor use for all weathers and varying temperatures?

It depends on the type of insulation and sheath it has.
There is blue PVC flex, blue HO5 flex and blue arctic flex on the market.
All three are being sold as 'arctic grade' but only one of them can actually stand up to external use.

Years ago it was acceptable to use blue arctic in the events industry, but it has not been allowed for a few years now due to there being so much blue flex around which is not suitable for outdoor use.

And if you do get proper arctic flex then you will find that, as the name suggests, it's main feature is flexibility at very low temperatures. It does not have the good mechanical strength of HO7-RNF which is the current standard.

Yes, I think that will be LSF/LSZH or to denote that it made to another specific standard.

But he did specifically ask about blue flex.
