On January 1, 2023, NSF will implement new extraction criteria for xylene, ethylbenzene and toluene. The extraction criteria found in the NSF/ANSI/CAN Std. 600 (NSF 600) reference standard will require all coatings in contact with potable water to meet new, lower extraction levels. These new limits will severely restrict available product offerings from most coating and lining manufacturers and only coatings with extractables of xylene less than 0.09 mg/L, ethylbenzene less than 0.14 mg/L and toluene less than 0.06 mg/L, will be certified for use on potable water structures and components.
