All,
The recently released D3 33 and 36 for PPU cold mass 01 have the same
SN: PPU-01 and SNType: ID. These don't appear correct to me.
SRF spec/procedure PR-P-007 (attached) defines the format of S/Ns. So,
to me, the SN for cold mass 01 should be 104211500-A002-A-001.
As to the SNType, CMASSN should be used.
The two specific D3 #33 & #36 address two issues associated with two
types of parts, the G-10 isolators and FPC bellows, respectively. If a
D3 is intended to address an issue with one certain part, e.g. only one
of the four FPC bellows, then I think the D3 should use the SN for that
specific bellows and SNType should be what we created for the FPC bellows.
Comments are welcome.
Gary
