Copper/nickel when scratched sows a White metal Copper is orange/red.
Also if the alloy is high in nickel a magnet will stick to it as nickel is attracted to a magnet.

That's not how it reads. It reads as requiring steel bundy tube meeting SAEJ1047 or an equivalent standard. I'll confirm with the engineer I'm working with and report back though, because it's clearly an issue.

[edit: the image didn't turn out well so I put the whole section in, you can see how they use the term "or equivalent" to mean an equivalent standard]

Yes, could be to individual engineers and road worthy establishments - best to check before using, but not an issue with a couple of places down here at least.

Interestingly the standard quoted is listed as cancelled on the SAE site, which could be why "or equivalent" has been included in the VSB. I deal with standards and legislation pretty regularly in my work, usually there is a working interpretation somewhere available so I might have to chase this with VicRoads on Monday and see where it goes.

Tried a magnet on my brake lines and it doesn't stick

There are markings on the brake tubing, this is a line I didn't need to use

The box the kit came in with sticker over dreaded copper word

My guess is the Automec kits advertised as "copper" on line are in fact copper nickel

Rego inspection time will be interesting, if my lines don't pass muster I will certainly be taking it up with the supplier

I looked in to the Automec lines a while back, and contacted them directly. They told me they could supply copper lines or copper nickel for the same price, and they listed a whole bunch of standards they complied too. When I checked all of the standards against the ADR regs, none of them matched.

In the I went for steel "bundy" tube lines as per the ADR regs. I had the lines made by Better Brakes in Southport QLD, total cost for all lines. flares and fittings, $130.

They may not last as long as copper or copper / nickel, but I know I am ADR compliant and I can't argue with that price.

Perhaps a silly question but if the lines were originally copper why would you need to change them to comply with an ADR that was issued after the build date of the vehicle? (unless you were engineering a modification that requires an engineers certification?)

As far as I am aware, all Landrovers ever built have had steel brake lines. Any copper lines will be replacements. Copper is (or rather was) preferred because of its ease of working and corrosion resistance, although corrosion of brake lines is not a serious issue in Australia where salt is not used on roads.

Originals were steel, at least on the IIA.

Fair enough, My series 1 has some copper lines but as stated they may be replacements. The line from the reservoir to the master cylinder is also copper but this would not be under pressure anyway.
