An insulator that is essentially thin, flat, and round in shape, with or without holes. The general shape may vary by the addition of such features as beveled edges, indented surfaces, through-hole key and/or peripheral flats. It may have one or more holes off center; if there are two or more holes, one may be centrally located. Excludes mounting pad, electrical-electronic component.

Indicates there is no information in the hmirs. The nsn is in a fsc in table ii of fed std 313 and a msds may be required by the user. The requirement for a msds is dependent on a hazard determination of the supplier or the intended end use of item.
Precious metal content is unknown
The item does not have a nuclear hardened feature or any other critical feature such as tolerance, fit restriction or application.
HMIC: Hazardous Material Indicator Code. Identifies a hazardous item.
PMIC: Precious Metal Indicator Code. 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.
Packing shall be accomplished to meet the performance test requirements of astm-d4169, distribution cycle 18, assurance level 1.
Packing shall be accomplished in accordance with table c.Ii for the packing level specified. closure, sealing and reinforcement shall be in accordance with the appropriate shipping container specification.
Options can be exercised as to specific method of preservation or dod approved packaging materials to be used. however, basic preservation method shall be retained, supplemental data shall be complied with, and unit package dimensions shall not be increased by more than one inch. equal or better protection shall be given the item and there shall be no increase in the package cost.
No special marking.
Preserve by method 10 modified as follows: preserve in transparent barrier bag made of a-a-3174 or type iii mil-prf-22191 material. a-a-3174 or mil-prf-22191, type iii material, a-a-3129 or ppp-c-795 cushioning shall be used to cushion sharp edges and protrusions of the preserved items. bag closure shall be made by any suitable means, except that staples shall not be used. when use of a bag is not practicable, the item shall be completely wrapped in the above barrier or cushioning material and secured with pressure sensitive tape. also, the use of shaped or molded packs utilizing mil-prf-22191 or a-a-3174 materials in conjunction with plastic coated board is acceptable provided the pack's cube is not increased and the pack meets the tests specified in appendix g. strip or block form of multiple packages shall incorporate provisions for separating unit quantities.
OPI: Optional Procedure Indicator Code. A one position alpha code that indicates the allowable deviations from the prescribed requirements.
SPI No.: Special packaging instructions number.
LVL A/B/C: Indicates the type of shipping container required for level A, B, or C maximum packing protection.
SPC Mkg: A two position code that identifies the special markings applied to the container, which is part of the total pack to protect the contained item during preservation, packing, storage, transit and removal from the pack.
MOP: Method of Preservation. Preventive measures to protect from deterioration resulting from exposure to atmospheric conditions during storage and shipment.
CUSH: Resilient material or devices used to absorb and dissipate energy from shock and vibration to adequately protect the contents and packaging components from physical damage during handling, shipment, and storage.
PRES MAT: Preservation Material. Identifies the material used to prevent or inhibit corrosion or deterioration of an item.
THK: Thickness of cushioning. Minimum thickness of material used to cushion the item.
TOS: Type of Storage. Type of storage space and environment conditions to be maintained for an item during storage and shipment.
