No the webway is tested to the latest version

Not according to Jim today I can forward his email to you if you like

Ive just looked yes your right.

Just to confirm, we tested to V2, not V3. We very much supported the direction that the BRE wanted to enhance EN50136 with V2.

V2 led the way for amendments to EN50136 (and this remains on-going) which brought the EN standard up to the level of LPS and allowed manufacturers like us and CSL to market in the UK and Europe (BRE/LPS1277 is not recognised outside of the UK) without having to go through two separate and very costly certification processes (its the thick end of 30k + every time you test/certificate, thats a lot of communicators you have to sell to get the money back!).

We may have included V3 as a strategy if BRE had accepted test reports from our EN based test houses, but they would not, and more importantly, it would have helped if they could certificate to EN, but they did not have the necessary accreditation to do so (I believe this is still the case). That meant we would have to have tested and certificated in two places for double the money!

LPS1277 is not recognised by the BSIA, nor the NSI and its a waste of time outside of the UK (as I said above), it is not a standard either. 

Specification of systems should be via the EN standards, nothing else.
