NSF/ANSI 222-2006e (R2011)
The objective of this standard is to provide a method to determine ozone generator production performance for water applications. This standard covers ozone generators that produce up to 500 g/h (26.4 lbs/d) of ozone. Devices utilizing actual mixing of the gas produced with water to be treated shall be precluded from this standard.
This Standard does not cover evaluating the effectiveness of an ozone generator for the treatment for water; it also does not cover structural integrity for ozone systems.
