The following modifications are being proposed to NSF/ANSI 61:
1. the inclusion of additional materials to Table 3.1- Material-specific analyses;
2. the inclusion of additional language to clarify what defines a piping system as flexible or rigid in Section 4, Pipes and Related Products; and
3. the removal of the option of exposing in-line devices for 16 hours and normalizing to 12 hours, in Section B.4 – Mechanical Devices, and Table B8 – In-line device exposure sequence. |
