In the Pre ISO versions of NACE MR 0175 one could see item number given below the title,

1) What is the significance of this item number
2) Are 21302 and 21304 the same or is there any specific reason for having 2 different item numbers for MR 0175?

Sorry bmoorty, I have no idea why is the item number there, mine is 21307 (ha ha), published 2005-09-01. That makes it three different item numbers so far. Any higher bet?
cheers,
