A previous ballot added clearance requirements to ASTM C1780 for MSV installed over frame walls. These clearances were taken directly from the International Building Code. During balloting, some changes were suggested for the explanatory Note 16 to include additional explanatory information. This ballot proposes to make those changes to the note.
Note that at the time that this ballot was issued, the current edition of this standard is C1780-23 but C1780-23a has been approved and will be issued soon. Changes in C1780-23a are incorporated in this ballot item.
