Just looking at cylinders (I have a 10L twinset I want to get shut of). I see one of our "premier" online shops still has M25 as the DIN size for regulators :D

Are people still farting about with M26? I thought it was dead now.

M25 is the norm for cylinders isn't it?! I thought M26 was high O2 % only?

M25 is the neck thread for the valve. (and a shit road I believe...)

Ah! Didn't know the cylinder neck had the same thread as the reg fitting of the valve. Shows how long it has been since I've had anything to do with a cylinder that isn't already assembled...
And it is a car park rather than shit road from my experience of it!

It doesnt. Neck thread is M25, outlet where the reg screws in is eithe G5/8 or M26. The neck doesnt change unless you'rr a Septic in which case it will be 3/4".

DIN=5/8", which is odd, because DIN is Deutsches Institut für Normung and you don't often catch ze Germans using imperial standards (if you'll pardon the pun)...

Many gas threads are still old imperial, this is because the thread pitch is better suited to brass fittings. Different metric thread pitches are available and are shown after a comma (e.g. M25,2 ) however most people are familiar with the standard metric thread pitch so it's simply easier just to use an old thread.

DIN is like BSI it doesn't really imply "Germanity" any more than BSI implies "Britishness". I think I'm right in saying that both are superseded by ISO now anyway, and the G5/8 is simply referred to as "DIN" as that is what it has become known as.

ISO is coming soon to a standard near you.
I've heard that some of the people who sit on these standards committees for the UK are being stopped by Government cuts.
They have been providing guidance to UK government and industry for years.
So if these guys are not able to stop Euro or International idiocy like what happened with M26 we may many more interesting things to deal with.

What makes you think it isn't the UK contingent that are the problem?

I have an experience of a dive center that all it's cylinders are M26, now as I have DIN they had a converter for my regs. For those that had A-clamp tough, you had to use their regs (TBF they don't charge extra).

I actually asked my local dive center about the M26 in Spain. He told me what we all know (nitrox etch) but in practice no one uses it. The ONLY exception is that the compressor at the center has to be M26 or he could be fined big time so he uses an adapter instead :)

The M26 problem came from Europe and was not voted for by the UK.
If the UK Government stop UK specialist attending these meetings then there will be more instances of the M26 situation.
This will not just be in the diving side of things but all industries

Rubbish.

The M26 norm was invented by ScubaPro to sell regulators. The UK government doesn't have any recreation dive specialist last I looked.
