6685-00-991-5461 Specification Set by the OEM (see RNCC code 3)
42.000in. ⁓42-1/64"
3.000in.
0.010in.
+25.5/+31.7in. absolute pressure below barometer
adjustable
0.250in.
can be used up to 3000 ft, 900 m, above sea level; double scale also reads 647 to 805 mm at 0.1 mm div; double scaled thermometer reads in c and f; mercury level and white zero pointer are clearly visible in glass cistern; white backing for cistern and meniscus; uniform bore 1/4 inch, 6.4 mm, so capillary depression is constant and taken into account in calibration; tube is in metal casing on 3 by 42 inch wood panel; mercury is included
adjust level of mercury pool so its surface just touches the white zero pointer which fixes zero point of column; use scale and vernier to read column height; make corrections for temp and gravity as shown in instructions, this will give true barometric pressure at desired location

Represents items with no adp components
The item does not have a nuclear hardened feature or any other critical feature such as tolerance, fit restriction or application.
Identification Codes
HMIC: Hazardous Material Indicator Code. A one position code that identifies a hazardous item.
PMIC: Precious Metal Indicator Code. A one position code which identifies items that have precious metals as part of their content. precious metals are those metals generally considered to be uncommon, highly valuable, and relatively superior in certain properties such as resistance to corrosion and electrical conductivity.
ESD: Electrostatic Discharge. Indicates if an item is susceptible to electrostatic discharge or electromagnetic interference damage. electrostatic discharge damage occurs when an accumulation of static electricity generated by the relative motion or separation of materials is released to another item by direct contact. electromagnetic interference damage occurs when an item comes into proximity with an electrostatic or magnetic field.
ENAC: Enviromental Attribute Code. Identifies items with environmentally preferred characteristics.
CRITL: Criticality Indicator Code. Indicates an item is technically critical by tolerance, fit, application, nuclear hardness properties, or other characteristics.

Material Codes
SOS: Source of Supply. A three position code or routing identifier code (ric), which identifies the source of supply activity.
SMIC: Special Material Indicator Code. A two position code, which categorizes material on the basis of requirements for source or quality control, technical design or configuration control, procurement, stocking and issue control, special receipt, inspection, testing, storage, or handling.
MMAC: Material Management Aggregation Code. A two position code that identifies an item of supply to be managed by a specific activity manager.
MCC: Material Echelon Code. A two position code employed by the marine corps in classifying items into categories by materiel category and procurement echelon. the alphanumeric management code is in the first position and identifies the materiel category
IMC: Denotes wether items shall be subjected to integrated management under the defense supply agency or retained by the individual military service or other department of defense components for their management. Assigned by th activity responsible for item management coding.
