Reaffirmation of Approved Standard

Under ANSI/VITA rules, every 5 years an approved standard must be reaffirmed, revised, or withdrawn.  The VSO by ballot feels that the following standard continues to be relevant to our community and is free from significant errors. Therefore, the VSO by ballot has recommended that this standard be reaffirmed.

There has been a request to incorporate an editorial errata in this standard. Given that the nature of the errata is to correct a error, it is recommended that it be corrected and put forth for reaffirmation.
The errata request is:
    P1w13-X38s+X8d+X12d should be referred to as P1w13-X38s+P2w7-X8d+X12d.

It needs to be fixed in
1.    Table 4.1
2.    Observation 3.3-1
3.    Observation 3.7-1

Consensus body registration for voting on ANSI reaffirmation of this standard is now open.
