  2. Revised example for ball valve normalization(DWA 61-2011-5) When looking for metal release, Section 8 requires the product to be exposed to a water volume close to the Vf(static) volume used during normalization.

  3. Revised example for ball valve normalization(DWA 61-2011-5) Proposal is to change the in-line device normalization example to reflect instances where test assemblies are used.
