1、Designation: D6881/D6881M 03 (Reapproved 2013)Standard Classification forStandard Plastics Industry Bulk Box/Pallet Unit SizeClassified By Bulk Density1This standard is issued under the fixed designation D6881/D6881M; the number immediately following the designation indicates theyear of original ado
2、ption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of lastreapproval. A superscript epsilon () indicates an editorial change since the last revision or reapproval.INTRODUCTIONAn ad-hoc survey in 2000 showed about 40 different box sizes in use by
3、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 classification covers containers used to hold plasticresins with bulk density (Test Methods D1895)of27to39lb/ft3(0.432 to 0
4、.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 to bulk boxes contain-ing hazardous materials.1.4 This classification does not address box/pallet unitiza-tion r
5、equirements.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 classification does not address tamping, shaking, orother compression methods of the resin filled bulk box tocondense entrai
6、ned 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 deliveries.1.8 This classification does not address filled bulk box/palletunit stack height.1.9 This classification does
7、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 units or inch-pound unitsare to be regarded separately as standard. The values stated ineach system may not be
8、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 does not purport to address all of thesafety concerns, if any, associated with its use. It is theresponsibility of
9、 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 organized collection ofinformation or a series of options and does not recommend aspecific course of action.

31、ry Information)A1. 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 oceancontainer that has an opening of 90 in. (2286 mm) at thecontainer entran
32、ce 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 The width requirement is to insure the bulk box orpallet/skid may be suitable
33、 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-tions (for example, the automotive and chemical drum indus-tries).A1.1.5 The we
34、ight 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 freight containers as well as truck load vans using palletswith a two-way entry (
35、no “pinwheeling” of the load isnecessary). 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 own performance standards and specifications.X1.3 Organizations that may be in
36、terested in this standardinclude:X1.3.1 Society of Plastic Engineers.X1.3.2 National Wooden Pallet and Container Association.X1.3.3 Technical Association of the Pulp and Paper Indus-try.X1.3.4 American Plastics CouncilAmerican ChemicalCouncil.X1.3.5 Society of Plastics Industries.D6881/D6881M 03 (20
