The following revisions are being proposed to NSF/ANSI 61:
1. The definition of “unit void volume” was added to section 2, Definitions;
2. Section 7.5.4.2 was revised to clarify exposure water requirements of adsorptive and non-adsorptive media; and
3. Section 7.5.5.4.2 was updated to reference collecting the unit void volume of the vessel rather than the 2 L or more referenced in 7.5.5.4.3. Section 7.5.5.4.2 was also revised to eliminate the collection of the first two exposure water samples. |
