What’s the difference between iso22241 and iso22241-1? My guidance received from Vw Van centre was to use the -1 variant to ensure warranty cover - Does it matter?

From MS Co-Pilot:
ISO 22241 is the umbrella standard, and ISO 22241-1 is the part that specifies the quality and testing of the urea solution. For vehicle owners, using DEF that complies with ISO 22241-1 ensures proper operation of the SCR system, while the broader ISO 22241 standard provides the framework for production, storage, and handling of the fluid.
