Glossary of Packaqinq Terms.

6 .3.1 Levels of protection. To help determine tbe extent of preservation-packaq inqrequired to protect a“ item agafnst specific hazards of storaqe, transportation, and handling,the Department of Defense has established three levels of protection whose main objectivesare to provide uniform, efficient, and economical protection to supplies and equipment. Thelevels of protectib” are based upon the performance expected of the packaqe. The performancecriteria can be summarized as :

(a) Level A. The degree required for protection against the most severe condi -~known or anticipated to be encountered d.rinq shipment, handling, andstoraqe. Preserv.stio”-packaging and packinq designated level A shall bedesigned for direct exposure to all extremes of climatic, terrain, opera-tional, a“d txansportatio” environments without protection other than that

prOvided bY the packaqe and pack. The .onditio”s to be considered includeb“t are “ot limited to:(1) Multiple rough h.”dling during transportation and intransit storage

from nm”.facturer to ultimate user.(2) shock, vibration and static loading durinq shipment, including deck

shiploading and offshore or over -the -bea.b discharge to ultimate user.(3) Environmental exposure during transit where port and warehouse

facilities are limited or nonexistent.(4) Extt?”ded unimproved open storage in .11 climatic zones, particularly

while under static loads imposed by stackinq.

15


MIL-P-2845c (SHIPS)

(5) Special package and pack features for field and combat operations(handling and utility] .

(6) special features are required by combat development agencies.(b) Level C. The degree required for protection under know” favorable conditions

~ shipment, ha”dli”g and limited te””re of storage. Preservation-

Pac~a9i.9 an? packing designated level c shall be designed to prote& itemsagaxnst physical and envxronrnental damage during know” favorable conditionsof shipment, handling and storage. In general , the followiny criteria willdetermine the requirements of level c.(1) Limited handling during transportation and intransit storage.(2) Limited shock, vibration and static loadinq during the tra”sportatio”

cycle .(3) Controlled warehouse e“viromnent for temporary periods.[4) Effects of environmental exposure during shipment a“d intra”sit delays.(5) Stacking and Supporting superimposed loads during shipment and temp,JrU-y

storage.(6) Item characteristics require no special or peculiar preservation-pack-

agi”q and/or packi”q provisions .

6 .3.2 Multiple trip container. The design features axe such that, subject to simplereplacement of components, the .Ontai”er can be employed for more than one ro””d trip frominitial supply source to the consumer and ret”r”. A typical example is a remountablewooden box/crate equipped with fasteners permitting ready assembly, disassembly, a“dreassembly.
