6 .3.1 Cleaninq the exterior of the beariim Dackaae before ODeninq. Thisnote is directed particularly toward instrument precision ball bearings,

although it can apply generally to all types After che bearing has left themanufacturer, s plant (or in the case of other bearings, the packaging

facility) properly packaged under clean room conditions, the exterior of the

package may become dirty. Containers and packages frequently generate small

amounts of Btatic electricity which attracts dirt and dust particles, and

contamination adheres to the package Particularly for instrument precisionball bearings, control should be established to clean the exterior instrument

precision ball bearings, control should be established to clean the exterior

parts of the package before entry into the processing area. A recommended

method is to,have the package blasted with absolutely clean dry air or remove

static electricity charge with an appropriate solvent. Once entering the

processing area and placed in a laminar flow hood, the package should be

washed again with the appropriate solvent for approximately 5 to 10 seconds to

remove exterior contaminant before being placed in a clean container ready to

be cut open. The package should be opened carefully so that there wil 1 be no

chips of the packaging material generated and the bearing should be removed

with stainless steel tweezers, or suitable handling too18. Bearing should

never be handled with bare hands or fingers

6.3.2 Bearinq cleanliness. Cleaning is a most important part of bearing

preservation. It is essential that the cleaning method not leave residues

which either may react unfavorably with the preservative, lubricant, or

packaging material, or may be unstable and decompose co form corrosive

residues.

6 .3.3 Bearinq (suDDort item~. When bearings are acquired by equipment

contractors for subsequent delivery to the Government as spares, proof of

conformance to the provisions of this document by the bearing manufacturer,

including the environment and process cleanliness provisions of 4.6, may serve

as the basis for Government acceptance.

6 .4.3 Packa.ainq. Definitions or explanations of packaging ternis shall be

in accordance with MI L-P-116, ANSI MH15 .1, ASlll D 996, and as described

herein.

6 .4.3.1 Levels of protection. The following levels of protection apply

e9UallY to Preservation and packing.

6 .4.3.1.1 Level A. This packaging provides maximum protect ion. It isneeded to protect material under the severest worldwide shipment, handling,

and storage conditions . Preservation and packing will be designed to protectmaterial against direct exposure to extremes of climate, terrain, and

operational and transportation environments, without protection other than

that provided by the pack. The conditions to be considered include, but arenot limited to:

(a) Multiple handlings during transportation and in-transit storage

from point of origin to final user.

(b) Shock, vibration, and static loading during shipment

(c) Loading on shipdeck, transfer at sea, helicopter delivery, and

offshore or over-the-beach discharge to final user.

[d) Environmental exposure during shipment or during in-transit

operations where port and warehouse facilities are limited or

nonexistent.

(e) outdoor storage in all climatic conditions for a minimum of 1

year.

(f) Static loads imposed by stacking.

NOTE: For packing (exterior containers ) the joint DOD packaging administra-

tors have determined and agreed that fiberboard and paperboard are

unacceptable materials for use under level A packing.

6.4 .3.1.2 Level B. This packaging provides intermediate PrOteCt iOn. It

is needed to protect material under anticipated favorable environmental

conditions of worldwide shipment, handling, and storage. Preservation and

packing will be designed to protect material against physical damage and

deteriorate ion during favorable conditions of shipment, handling, and storage.

The conditions to be considered include, but are not limited to:

(a) Multiple handlings during transportation and in-transit storage.(b) Shock, vibration, and static loading of shipments worldwide by truck,

rail, aircraft, or ocean transport

(c) Favorable warehouae environment for a minimum of 18 months.(d) Environmental exposure during shipment and in- transit transfers,

excluding deck loading and offshore cargo discharge.

(e) Stacking and supporting superimposed loada during shipment andextended storage

NOTE : For packing (exterior containers ) weather ree. iatant grades of fiber-

board and paperboard are permitted under level B. Domestic type or grade

(non-weather-resistant) fiberboard and paperboard are unacceptable under levelB packing.

6 .4.3.1.3 Level C. This packaging provides minimum protection. It is

needed to protect material under known favorable conditions The following

criteria determine the requirements for this degree of protection:

temporary storage.

6.4.3 .1.4 Qw!EKUU. Although not specifically defined by anyGovernment regulation or instruction, commercial packaging (preaervacion andpacking) is understood to be those practices by the manufacturers andauppliera to protect and identify material and items packaged for retail andwholesale distribution purposes. ASTM D 3951 provides guidance in the

application of commercial packaging. Joint ODD instruction haa determinedthat commercial. also in some areas addressed as industrial, packaging shouldbe used or specified only when such packaging is known to satiafy the DDDneeds. Such uae should be determined before a contract for supplies isawarded or within the life cycle of che contract when subatancial savings cothe Government may reau1t. Commercial (industrial) packaging should not bespecified where multiple shipments and handlings are anticipated or desired.

6.4.3.4 ~. The inner bag or wrap used directly againat

the bearingl bearing component.

6.4.3.5 ~. Marking ia the application of numbers, letters, labela,

taga, aymbola, or colors for handling or identification during shipment andstorage.

6.4.3.6 ~. MilitaCy packeging refera to the imeterhla

and machoda or procedures prescribed in Federal and Militaxy apecif icationa,standards, drawings, or other authorized documents that are designed toprovide the degree of packaging protection determined neceaaaw to preventdamage and deterioration during worldwide distribution of material.

6.4.3.8 ~. Packaging is the process and procedures used toprotecc material fram deter ioration and damage. IL includes cleaning, drying,

preserving, packing, marking, and unitization.

6.4 .3.9 ~. Packing refera to the aaaerbling of items into a unit,intermediate, or exterior pack with necessary blocking, bracing, cushfOnfng.weatherproof ing, reinforcement, and marking.
