1、Designation:F273408Standard Practice forTesting the Shelf Life of Ink Jet Printer Cartridges1This standard is issued under the fixed designation F2734;the number immediately following the designation indicates the year oforiginal adoption or,in the case of revision,the year of last revision.A number
2、 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 describes a practical procedure to helpdetermine the shelf life confidence of a sample ink jet cartridgein a short period of time.T
3、his practice uses an acceleratedaging test based on theArrhenius principle which states that forevery 10C increase in temperature there is,approximately,atwo times rate increase of a chemical reaction.1.2 This practice consists of comparing the ability of an inkjet cartridge to print after exposure
4、to elevated temperature ascompared to a reference ink jet cartridge,such as an OEM(original equipment manufacturer)ink jet cartridge.1.3 This practice can be used to evaluate the effectiveness ofthe overall production of remanufactured or refilled ink jetcartridges.1.4 To confirm the results of acce
5、lerated aging,real-timeaging should also be conducted.1.5 The values stated in SI units are to be regarded asstandard.No other units of measurement are included in thisstandard.1.6 The values stated in inch-pound units are to be regardedas standard.The values given in parentheses are mathematicalcon

8、ractice4.1 This practice describes a method to compare the shelflife of a sample ink jet ink cartridge as compared to a referenceink jet ink cartridge by exposing each cartridge to elevatedtemperatures and comparing their ability to function.4.2 Based on previous elevated temperature testing withint
9、he industry,exposure to 60C for 21 days is roughly equal toa shelf life of one year.This statement is for guidance as thistest procedure is more comparative than predictive.It is notconfirmed that there is a linear relationship between thenumber of heating days to shelf life(that is,60C for 42 daysm
10、ay not be equivalent to two years shelf life).5.Significance and Use5.1 This practice can be used to determine the stability andperformance of ink jet ink when exposed to elevated tempera-tures in an ink jet cartridge.5.2 This practice can be used for the evaluation of an OEMor other reference ink j
11、et cartridge compared to a correspond-ing remanufactured,or refilled,or other sample ink jet printercartridge.5.3 This practice is applicable to all ink jet cartridges,whether single or multicolor.5.4 This practice can be used to assess design goals ofmanufacturers of ink jet printer cartridges for
12、ink capability,ink filling,and packaging effectiveness.5.5 Thispracticemaybeusedforresearchanddevelopment,and for quality acceptance evaluation.6.Interferences6.1 Print testing should be performed at a controlled tem-perature and humidity within the operating range of the printer.All equipment and m
13、aterials should be conditioned in the testatmosphere for at least 24 h prior to testing.6.2 Test printers should be in good mechanical and electri-cal condition.Any printer failures can invalidate the test.1This practice is under the jurisdiction of ASTM Committee F05 on BusinessImaging Products and
