With all this talk of dodgy cables cropping up I was a bit surprised when I ordered some NYY-J cable for some exterior lighting that I've got coming up.

The stuff that arrived was far thinner than I expected (cores still what you'd expect, but much thinner jacket)

It's stamped, - turns out to be CYKY cable from Czech republic.

So in terms of manufacturers' data it seems fine for CCC, working temps, insulation etc. But in terms of standards, there's no iec / en no stated except for colour ids and flame propagation.

Is this okay to use and still comply with 7671?

Dave.

You might want to have a look at 133.1.1, 133.1.2 and 131.1.3. I think the answer to your question is No.

133.1.1, 133.1.2 and 131.1.3

Would it not pass on the 'appropriate standard of another country' clause - being that a BS or HD for that type of cable doesn't exist?

Thanks John, FM and AJ.

Yes, - it's a bit tricky. I'm complaining to the wholesaler, as it's not what I ordered, however it's from what seems to be a big manufacturer, and has the following approvals: HD308 S2 (which I think is just about insulation colour IDs) and EN 50 65- -1,
IEC 6033 -1- which I think are flame propogation tests.

Looking at NYY-J cable on TLC's site; theirs is approved to BS EN60228 - which would do it for me, so I might just send this stuff back.

The spec does say it has these test certificates:

Test certificate: EZÚ Czech Republic,
GOST Russia,
EVPÚ Slovak Republic

But does this count for anything!?

Cheers,

Dave.
