ASTM F215307 背包容量的测量（中英对照） 1.Purpose andScope目的和范围1.1This test method determinesand standardizesan unextendedand extended capacity forbackpacks andrelated bags.Related bagsinclude lumbar packs,soft rucksacks,internal andexternal framepacks,duffel bags,and travelpacks本方法规范和标准化背包和相关包包的可扩展或不可扩展的容量。 相关的包包包括腰包，软帆布包，内部和外部框架包，行李包和旅行包。 1.2This testmethod is designed toprovide ameans wherebymanufacturers andconsumers may have aconsistent meansto parepack volumes.本方法目的是提供一种能使制造商和消费者有一致的手段去比较包包容量方法。 1.3This testmethod does not takeinto consideration areas of the backpack that arenot pletelyenclosed byfabric suchas meshpockets,water bottleholders,and pressorpockets.本方法不考虑背包上如网布，水杯袋和压缩口袋等不完全由布片封闭的区域。 1.4For practicalpurposes thistestmethodcannot beused tomeasure capacitiesless than4L.出于实际使用的目的，本方法不适用于测量4L以下的容积。 1.Reference参考标准/2.Definition定义2.1.1backpack,nany carryingdevice constructed of fabricthat utilizesa singleor doubleshoulder strapas themeans forthe wearerto carrythe

BackpackCapacityAll partments(including mainpackbody,toppocket,exterior pockets)are filledwith20-mm plasticballs to their extended capacity.Balls areremoved tobring thepack downto itsunextended capacity.The removedballs aretemporarily stored.The restofthepack isemptied andthe capacitymeasured in the graduatedcylinder asthe unextended capacity.The ballsremoved inthe firststep arethen addedto the cylinder tomeasure the extendedcapacity.4.Apparatus,Reagent andMaterial设备、试剂和材料4.1Spheres(see Fig.1)15to20-mm hollowpolypropylene,polyethylene,or otherfunctionally inpressibleplastic,measurement unitswith density between6and14lb/1000in3.(A usefulquantity is1900020-mm ballsor19cases of1000=7500in.3(approximate).)直径15到20的中空聚丙烯，聚乙烯或其他不能被压缩的塑料球，净密度在6到14lb/1000立方英寸4.2Cylinder(see Fig.2)A verticalwalled flat-bottomed cylindermadeofrigid materialwith adiameter between14and18in.圆筒由坚硬材料做成的直径在14到18英寸垂直平底圆筒4.3Measurement ToolA pistonthat willapply aforce of0.01psi onthe ballsand beused tomeasure theheight ofthe ballsinthecylinder.测量工具可提供0.01psi压力的活塞，用于测量圆筒中球的高度。 5.Safety andPPE Information健康和安全信息/6.Procedure测试方法6.1Determine capacityas follows:确定容积的步骤如下6.2Remove allhangtags andpackaging.移除所有的吊牌和包装6.3Note thebackpack manufacturer,model,size,weight,technician,and date.记录背包的制造商，型号，尺寸，重量，检查员和日期6.4Loosen allstraps toeliminate anyconstrictions sothepackmay achieveits largestcapacity.松开所有的绳索带子，防止包包被压缩，确保包包能达到其最大容量。 6.5Fill themain partmentwith the spheres,making surethespheresare oupyingall thecorners.Tamp thefilled packto fill all voids.Continue fillingand tampinguntil themain partmentis fullin aordancewith thedefinition forextendedcapacity(2.1.4).往主袋填入塑料球，确保塑料球佔满所有的边角。 捣实背包，继续边加边捣直到主袋容量达到包自身定义的一致。 6.6Continue tofillallenclosed partmentstotheirmaximum capacity,making surethe partmentsare filledand closed.继续填充所有附袋到其最大容量，确保所有的袋子填满和闭合。 6.7Tamp andmassage thepockets toremove areasnot filledwith balls,and continueuntil full.捣实和挤按袋子，移出没有加满球的区域，继续加到满。 6.8Remove andstore the balls thatwill reducethepackfrom itsextendedcapacityto itsunextended capacity.移开和存放袋子中的球，先从可延伸的部分再到不可延伸的部分。
