Pursuant to SOP 2-100, notification of this proposed standards activity is being announced to demonstrate the opportunity for participation by all directly and materially affected persons. Any comments asserting that a proposed standard duplicates or conflicts with an existing consensus standard developed by another recognized organization should be sent to [email protected] within thirty (30) days from the publication date of the announcement (i.e., no later than February 15, 2017).
