Is VNA 675116 the Standard for Measuring Cold Index in Valves?

[gabriel]

Hi,
I work with valves and one of our customer send me an oring specification. this file says that the index (or coefficient) of cold is -50°C and it was measured with differential scaning as per VNA 675116. I have never heard something about it.
thanks

Hi gabriel,
VDA 675116, not VNA. It's a German standard, but that's all I can tell you.
