Standards for Presta Valves

[rothers]

Does anyone know of any standards for Presta tyre valves ?

I know of the IEC standards for Schrader valves, i.e ISO 4570, ISO 9413 & ISO 20562 but have never seen anything for Presta.

According to Google, ISO 4570.

Thanks but ISO 4570 is just for the threads.

I'm after the equivalent of ISO 9413 & 20562 which specify valve cores & valve bodies for Schrader.

It may be that no one is interested in paying to have a standard issued. Manufacturers spend money on sending representatives to meetings and pay for them to write the standards. It is possible no one making Presta valves cares to contribute the probable $10,000+ minimum to buy getting one published.
