According to ISO 8655-6 Annex B, we can use a simplified equation to assess the uncertainty

u = Es + 2Sr.

My question: What is the volume range we can use for the equation?

Or for what's the volume range (small volumes) we must provide for a complete evaluation, given in ISO 20461.

Thanks.

*u*of the delivered volume at the 95 % confidence level:u = Es + 2Sr.
