Heat shrink/sleeving for power supply wire?

[ramshackles]

Hi
I'm looking at heat shrink/sleeving and wondering which is best for hookup wire carrying power supply:

1. Power from mains inlet to power transformer (so short length of wire, 240V)
2. Power from output of power supply to audio equipment (potentially long if external power supply)

I can put a value on the internal diameter needed by the size of my hookup wire, but I still have a plethora of choices regarding material thickness, heat shrink or sleeving etc..

Are there any standards for these things?

I tend to use 3M brand heat-shrink because Mouser is somewhat nearby.  Mouser usually stocks what I need.

Looks like the stuff is rated for 600 Volts.

OTOH, if building a gizmo for commercial sales worldwide, I dunno if those 3M products will meet the standards.

In the USA, a "gizmo" usually has  to be tested at an "approved lab", and they will literally abuse the test item until it is melted down before they will issue a "UL Accepted" sticker.

No UL sticker required for DIY, but if your Gizmo blows up and burns down the house...it may get sticky dealing with the Homeowner's insurance company.

I always worry....

We (day job) use a sleeve material rated for and approved by TÜV for this application (mains connector/fuse to circuit board). I'll ask the tech what we buy. It's not a heat shrink material, it's a sort of heavy but flexible (accordion-ish) rubber-like material, white on the outside.
