Correct Answer: Standard requisition form
1. NAVSUP 1250-2 is another version of the standard requisition form, sometimes used for specific transaction
types.

8: What does NSN stand for?
Correct Answer: National Stock Number
1. NSN is a 13-digit number assigned by the Defense Logistics Information Service (DLIS) to uniquely identify an
item of supply.

9: What are the components of a National Stock Number (NSN)?
Correct Answer: 4-digit Federal Supply Classification (FSC) + 9-digit National Item Identification Number (NIN) —
total 13 digits assigned by DLIS
1. FSC: first 4 digits (2 for group, 2 for class) — identifies category of item (e.g., 5310 = nuts and washers).
2. NIN: last 9 digits; first 2 digits are NCB code (country); last 7 digits are non-significant identification number.
3. Example: 5310-00-123-4567 (FSC=5310, NCB=00, NIN=00-123-4567).
10: What is a cognizant symbol?
Correct Answer: Identifies a stock numbered item with Navy inventory manager and segregates items into more
manageable groups
1. Cognizant symbol (Cog symbol) is a two-digit code identifying the Navy inventory manager responsible for
stocking and managing an item.
2. Examples: "1S" for shipboard consumables, "3Z" for torpedoes.
3. Helps in organizing supply chain and assigning responsibilities for procurement and stocking.
11: What does FSC stand for?
Correct Answer: Federal Supply Classification (4 digits: 2-digit group + 2-digit class)
1. FSC is the first 4 digits of the NSN. The first 2 digits identify the Supply Group (e.g., 53 = hardware). The last 2
digits identify the Class within the group.
2. Example: 5310 = Nuts and Washers (Group 53 = Hardware, Class 10 = Nuts and Washers).
3. Maintained by the General Services Administration (GSA) through the Federal Catalog System.
12: What does NCB stand for?
Correct Answer: National Codification Bureau — the country that assigned the stock number
1. NCB is a 2-digit code as part of the NIN. "00" and "01" represent the United States.
2. Other countries have their own NCB codes (e.g., "12" for Germany).
3. The NCB code identifies which country's military supply system originally assigned the NSN.
