3、c 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)of 27 to 39lb/ft3(0.432 to 0.625 g/cm
4、3).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 requirement
5、s.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 entrained air and

7、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 exact equival
