1、Designation: F2825 10 (Reapproved 2015)Standard Practice forClimatic Stressing of Packaging Systems for Single ParcelDelivery1This standard is issued under the fixed designation F2825; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision

2、, the year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope1.1 This practice provides a uniform basis for evaluating, ina laboratory, the ability of a packaging system

3、 to withstand arange of climatic stresses that a packaging system may beexposed to during distribution throughout the world and stillprovide the product protection from damage or alteration.1.2 This practice is designed as conditioning prior to testingfor overnight or two-day delivery systems of a s

4、ingle parcelpackaging system or as a standalone test for climatic stressingof packaging systems.1.3 This practice does not cover refrigerated, frozen foodstorage, or cryogenic storage conditions. Only the climaticenvironments encountered in various regions of the world arecovered by this practice.1.

5、4 The values stated in SI units are to be regarded asstandard. No other units of measurement are included in thisstandard.1.5 The values stated in inch-pound units are to be regardedas standard.

Summary of Practice4.1 Products shipped through the distribution environmen

9、t,regardless of mode of transportation, encounter various cli-matic and physical environments as they pass through differentparts of the world at various times of the year. This practice isdesigned to provide guidance when establishing the climaticstresses imparted to packaging systems using expecte

10、d climaticconditions and durations that they can encounter in distributionin order to evaluate its ability to provide protection to thepackage contents or devices.5. Significance and Use5.1 This practice provides a method for conditioning pack-aging systems using climatic conditions that occur in ac

11、tualdistribution. The recommended exposure levels are based onavailable information on shipping, handling and storageenvironments, current industry practices, and published stud-ies. They are not absolute extremes, but recorded daily aver-ages in cold and hot climates of the world.6. Apparatus6.1 Ro

12、om (or Cabinet) of such size that sample containersor packages may be individually exposed to circulating air atthe temperature and relative humidity chosen.1This practice is under the jurisdiction of ASTM Committee F02 on FlexibleBarrier Packaging and is the direct responsibility of Subcommittee F0

United States16.1.1 Control Apparatus, capable of maintaining the room atthe required atmospheric conditions within the tolerance limits.6.2 HygrometerThe instrument used to indicate the rela-tive humidity should be accurate to 6

16、2 % relative humidity. Apsychrometer may be used either for direct measurement ofrelative humidity or for checking the hygrometer (see TestMethod E337).6.3 ThermometerAny temperature-measuring device maybe used provided it can accurately indicate the temperature towithin 0.1C or 0.2F. The dry-bulb t

17、hermometer of thepsychrometer may be used either for direct measurement or forchecking the temperature-indicating device.7. Procedure7.1 Define Packaging SystemDescribe the packaging sys-tem in terms of size, weight, and materials of construction andestablish the unit of test (shipping box, multipac

18、k, pallet load,and so forth).7.2 Identify the various modes and durations of transporta-tion that will be used to store and distribute the products tocustomers. For example, the product will be delivered to itsdestination via truck and air over a two-day transit period.7.3 When used as a standalone

19、test, predetermine theacceptance criteria.7.4 Write a test plan using the sequence, conditions andexposure times cited in Table 1. If data is available for theusers distribution environment indicating different conditionsand exposure times, they should be used.NOTE 1Exposing packaging system materia

20、ls to warm/humid climaticstresses first may cause the materials to absorb moisture that may remainwith the materials throughout the remaining exposures.7.5 Conditions and exposure times may be based on knownstorage and distribution systems and conditions.7.6 Test Specimen:7.6.1 Test specimens should

21、 consist of representative pack-aging systems, including actual contents or devices. Contentswith blemishes or minor defects may be used if the defectivecomponent is not to be studied and if the defect is documentedin the report. Simulated contents are also acceptable as long asthey duplicate the lo

22、ad characteristics of the actual contents.7.6.2 Care must be taken to ensure that no degradation hasoccurred to both the packaging system and the contents prior toinitiating the climatic stress exposure. This is particularlyimportant in situations where the samples are shipped to aremote test site.7

23、.7 Perform climatic conditioning per the plan.7.8 Continue with the packaging system performance test orevaluate the results of the conditioning against any predeter-mined acceptance criteria when performing a standalone test.8. Climatic Conditions8.1 The conditions listed in Table 1 are based on in

24、dustryexperience, global climate, time products spend in distributionsystems and guidance from Practice D4332 and ISO 2233.9.

25、.1.2 Statement of compliance with this procedure.9.1.3 Variations from this procedure, including the testingtemperature and relative humidity, if different from the condi-tioning atmosphere, the time elapsed, and so forth.9.1.4 When used as a standalone test, whether the accep-tance criteria have be

27、 1The time between each condition should be documented in the test plan. It can be determined by the user. It may be as little as no time betweenconditions (worst case) or up to several hours depending on factors as distribution environment data, test facility capacities and test schedules. If thean

28、ticipated time between exposures will exceed one hour, a controlled storage condition such as 23 5C and 50 10 % relative humidity (RH) shouldbe considered.Condition Description Temperature Relative Humidity Exposure Time1 Cold 20 3C not specified 4 h +30 min/02 Controlled Room Conditions 23 5C 50 10
