They don't noramally have markings, so a letter is required from the manufacturer.

I'm not sure if the pipe itself and the unions are considered different components. Someone will be along shortly with a more technical
answer.

greate - I've just spent most of today fitting braided hoses on the front 
I think you alwo need to wrap them as the braiding is considered sharp!
will an RD catalogue and packet be enoiugh?

If they are Goodridge series 600 or equivalent then they are OK, I believe that the fittings have a G stamped on them, the hoses are not marked. I
took the Goodridge catalogue, assembly instructions & a sample fitting to my SVA just in case but the engineer never questioned them. The 600
series fit the SVA requiements as in the manual, see below

It is suprising how abrasive that braiding is! If the braided hose is covered with a plastic coating they are deemed as ok (abrasion wise anyway)

Is spiral wrap good enough for this?

Before I did my SVA about 18 months ago, I spied out the 2 nearest SVA centres (Norwich & Chelmsford) and took a couple of brake hose fittings
with me. I asked testers at each centre for their opinion on them - and both said that they wouldn't be happy with them, and would ask
questions. In the end I bought some hoses with crimped fittings, simply because the testers wouldn't query them.
The hoses shouldn't rub anything at either lock, so the fact that the braid makes a good file against anything it touches should be
irrelevant... but at one lock my hoses lay against the side of the caliper - just like the rubber originals did. The originals had extra heavy
sleeving at that point, so I put some spiral wrap held on with heat-shrink tubing in the same place.
Of course, if the hoses touch a wheel or tyre at any point of the lock then that's an instant fail, whether it's braided or rubber
hose.

ironically I just bought some and I noticed that they are Speedflow items that screw together rather than crimped.
They definatelly had an inner washer type thing and are designed for high pressure brake applications..... but I are these still likelly to fail?

Unfortunately, it's a lottery. Some testers will fail them, others will pass them

It does seem that way!
About time that the testers that are failing them despite the manual clearly stating that they are ok (as lonf as they are the right type of screw
together ones) were kicked into touch on this one.
Its a bit like the handbrake cable fiasco that cost a lot of folks on here extra work just because one particular tester was failing them on a whim.
