H07RN-F water resistant, waterproof?

[WhydidIstart]

Hi, I'm hoping someone can shed some light on cables suitable for the garden (SWA to junction boxes above ground and then IP68 gand and short waterproof cable to light fittings required).

I had thought H07RN-F was a tough, rubber cable suitable for 'outdoors' type applications where the cable may see a bit of wear and a bit of water and was 'water resistant' (but should not be submerged for long periods). I also thought H07RN8-F was the waterproof version as used for cables burried in the ground (likely to be wet for long periods) and lights / pumps in ponds, etc.

However this site
http://lapplimited.lappgroup.com/pr...s/harsh-conditions/rubber-cables/h07rn-f.html
lists a H07RN-F enhanced version that seems to be waterproof (AD8 test) to 100m and the datasheet marks it with a 'waterproof' symbol whereas the standard H07RN-F and also the H07RN8-F don't get the waterproof mark.

This site http://www.cablechoiceguide.co.uk/cables/rubber-cables/h07rn8-f/ then tells me that H07RN8-F isn't really waterproof: "Temporary use in water: a maximum of 2 weeks at a time (transversely waterproof), subsequent drying-out required."

I'm now confused as to what the markings actually mean. Ok manufacturers' datasheets should be the deciding factor, but I don't see how to easily check what I have, or what I buy is suitable, can anyone shed any light please?

If you look at the table - //www.diynot.com/wiki/Electrics:harmonized-wire-code - you'll see that the codes only describe the construction of the cable.

The manufacturers data sheets are the only place you can find out if Brand A cable is "fully waterproof".

I don't see how to easily check what I have, or what I buy is suitable

By buying cable made by a manufacturer who says it has the characteristics you want.

Thanks, I guess I had been assuming that the construction of the cable, including materials used, would lead to a certain performance level - such as being waterproof for example. However it appears that's not the case.

I'm a bit concerned that when I have something like below, or even have it delivered that I'm not 100% sure they have sent me the correct cable, or haven't simply substituted manufacturers, etc. I guess I just have to live with that.
