3、6881/D 6881M in August 2008.INTRODUCTIONAn ad-hoc survey in 2000 showed about 40 different box sizes in use by the plastic resin industry;the purpose for this classification is to quantify a box/pallet unit size acceptable for this industry withinthe limits of the scope.1. Scope1.1 This classificati
4、on covers containers used to hold plasticresins with bulk density (Test Methods D 1895)of27to39lb/ft3(0.432 to 0.625 g/cm3).1.2 This classification does not apply to any plastic resinswith bulk density below 27 lb/ft3(0.432 g/cm3) or above39lb/ft3(0.625 g/cm3).1.3 This classification does not apply
5、to bulk boxes contain-ing hazardous materials.1.4 This classification does not address box/pallet unitiza-tion requirements.1.5 This classification does not address requirements ofplastic bag liners normally placed inside the corrugated bulkbox before filling with plastic resin.1.6 This classificati
6、on does not address tamping, shaking, orother compression methods of the resin filled bulk box tocondense entrained air and increase headspace in the bulk box.1.7 This classification does not address blocking and brac-ing or other shipping requirements normally associated withbulk box unit deliverie
7、s.1.8 This classification does not address filled bulk box/palletunit stack height.1.9 This classification does not address international ship-ping regulations of bulk box/pallet units.1.10 This classification does not address pallet openingsizes for pallet trucks.1.11 The values stated in either SI
8、 units or inch-pound unitsare to be regarded separately as standard. The values stated ineach system may not be exact equivalents; therefore, eachsystem shall be used independently of the other. Combiningvalues from the two systems may result in non-conformancewith the standard.1.12 This standard do
9、es not purport to address all of thesafety concerns, if any, associated with its use. It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory requirements prior to use.1.13 This classification offers an

Basis of Classification5.1 The bulk box will contain about 1000 to 1600 lb (453.6to 725.7 kg) of plastic resins with typical bulk densities of 27to 39 lb/ft3(0.432 to 0.625 g/cm3).5.2 Minimum performance of the b
25、ulk box pallet unitduring pack out, storage, and transit will be specified by theuser.5.3 Total height of box, cap, and pallet (container height)equals 44 634-in. (1118 6 19 mm).5.4 Total width of pallet (container footprint width) equals45 614-in. (1143 6 6.35 mm).5.5 Total length of pallet (contai
26、ner footprint length) equals48 614-in. (1219 6 6.35 mm).5.6 Bulk box “freeboard” on all sides of the pallet will bespecified by the user.5.7 Corrugated fiberboard bulk boxes are normally used inthis application; the octagon-shaped box is preferred becauseof the superior strength/capacity weight over
27、 rectangular cor-rugated boxes.5.8 Wooden pallets are typically used in this application butmay be of other materials of construction; the required foot-print will allow the user an option to choose either four- ortwo-way entry.5.9 The eight corners of the octagon bulk box must besupported on top an

BULK BOX STANDARD CLASSIFICATION SUMMARYA1.1 Criteria in setting dimension limits include:A1.1.1 The height requirement is to insure that the doublestack container (normal fork truck load) will enter the o
32、ceancontainer that has an opening of 90 in. (2286 mm) at thecontainer entrance door.A1.1.2 The width requirement is to insure two containerswill fit side by side in truck vans and ocean containers withadequate space for fork truck loading. Inside ocean containerwidth equals 92 in. (2337 mm).A1.1.3 T
33、he width requirement is to insure the bulk box orpallet/skid may be suitable for use in multi-industry applica-tions (for example, the automotive and chemical drum indus-tries).A1.1.4 The length requirement is to insure the bulk box orpallet/skid may be suitable for use in multi-industry applica-tio
34、ns (for example, the automotive and chemical drum indus-tries).A1.1.5 The weight requirement is based on the volume ofthe bulk box and bulk density of the plastic resin.APPENDIX(Nonmandatory Information)X1. GENERAL USE AND GUIDANCEX1.1 The size requirements are based on being able to loadocean freig

User may specify pallets with four-way entry.X1.2 Since the box will be used by a wide variety of userswith different storage and transit requirements, each user mayutilize their ow
