15、r Drive, PO Box C700, West Conshohocken, PA 19428-2959, United States.8.2 Test pumps should be tested no sooner than 24 h afterassembly when possible. If pumps are not conditioned at therecommended time, this should be noted in the test reportdiscussed in 11.9. Test Specimen Preparation9.1 Prepare a
16、 minimum of 12 mechanical pump dispenserswith product and containers to be used for accelerated usageevaluation.9.1.1 Affix the mechanical pump dispensers to containers atthe minimum recommended torque load in accordance withTest Method D 2063.9.1.2 Label all of the assembled units with the productn
17、ame, any safety hazards for the product, name of thetechnician completing the test, and the test number or means ofidentifying the test along with the following:9.1.2.1 Minimum 3 units labeled, “Upright, Ambient.”9.1.2.2 Minimum 3 units labeled, “Upright, Oven 45C.”9.1.2.3 Optional: Minimum 3 units
18、labeled, “Upright, CycleChamber.”9.1.2.4 Minimum 3 units labeled “On-Side, Ambient.”9.1.2.5 Minimum 3 units labeled, “On-Side, Oven 45C).”9.1.2.6 Optional: Minimum 3 units labeled “On-Side, CycleChamber.”10. Procedure10.1 Test each mechanical pump dispenser for strokes toprime in accordance with Tes
19、t Method D 3890. Report thefindings in 11.1.10.2 Test each mechanical pump dispenser for output perstroke in accordance with Test Methods D 4336. Visuallyinspect the spray or flow of the product to ensure that noobstructions are present.10.3 Place all of the test specimens as prepared in 9.1 intheir
20、 respective environments as indicated by the appropriatelabel on each unit. Except for trigger sprayers, place specimenslabeled “On-Side” with the orifice facing down. Triggersprayers may have the orifice oriented to the side while in the“on-side” position. If the mechanical pump dispensers use apro
21、tective hood or overcap, these test specimens should bestored with their protective devices in place. If the mechanicalpump dispensers have a locking feature, these test specimensshould be stored in the locked position during storage andunlocked for testing.10.4 Except for trigger sprayers, remove a
22、ll of the testsamples from their respective environments three times perweek, (preferably Monday, Wednesday, and Friday), over afour week period for a total of 12 test days.10.5 For trigger sprayers, remove all of the test specimensfrom their respective environments once every two weeks fora duratio
23、n of 12 weeks for a total of 7 test days.10.6 Allow the temperature of the test specimens to equili-brate (generally 4 to 6 h) to ambient temperature prior to theactual evaluations.10.7 Evaluate the primed mechanical pump dispensers foreach of the following parameters:10.7.1 LeakageVisually inspect
24、for the presence of prod-uct on the outside of either the mechanical pump dispenser orthe container. If any test specimen exhibits a high degree ofleakage, discontinue any additional testing with that particularmechanical pump dispenser and report the findings in 11.1.10.7.2 Retention of PrimeFully
25、stroke each mechanicalpump dispenser to determine if the mechanical pump dispenserhas retained its prime. If any test specimen has lost prime andit is unable to be reprimed, then discontinue any additionaltesting with that particular mechanical pump dispenser andreport the findings in 11.1.NOTE 3If
26、the mechanical pump dispenser fails to re-prime as a resultof a clog, then try cleaning in accordance with 10.7.3 before concludingthe test.10.7.3 CloggingVisually inspect the orifice of each me-chanical pump dispenser for the presence of product, either asis, or in a dried state and report the find
27、ings in 11.1. If the pumpexhibits a high degree of clogging, which interferes with theperformance of the mechanical pump dispenser, try removingthe dried product from off the face of the orifice. If this does notremedy the clog and results in an unusable mechanical pumpdispenser, discontinue any add
28、itional testing with that particu-lar mechanical pump dispenser and report the findings in 11.1.10.7.4 Output per StrokeDetermine the output per stroke(in accordance with Test Methods D 4336) of each mechanicalpump dispenser per D 4336.10.7.5 Spray QualityObserve spray quality. Report anyleakage and
29、 location in 11.1.10.8 Upon completion of the testing outlined in 10.6, returnall functioning test specimens to their respective environmentsfor continued testing at the next scheduled time interval.10.9 Retain all test specimens that were discontinued fromtesting because of one or more defects. Sav
30、e these if futureexamination is required.11. Report11.1 Report the following information:11.1.1 Description of the mechanical pump dispenser (sup-plier, type, closure size, diptube length and application torqueof closure to bottle),11.1.2 Identification of the product used,11.1.3 Statement to the ef
31、fect that the tests were made incompliance with this test method along with the:11.1.4 Name of the technician completing the test, and11.1.5 Date of report along with dates for the test period.11.1.6 Detailed record of test on each mechanical pumpdispenser,11.1.7 When a mechanical pump dispenser was
32、 discontin-ued from additional testing and the nature of its discontinu-ance, and11.1.8 Any observations or recommendations that may as-sist in correcting the various defects report upon.11.1.9 Data for each package on strokes to prime anddelivery rate. Identify any patterns or trends seen in thedel
33、ivery ate of the packages during the test.11.2 Report the overall results of the testing and draw aconclusion as to the acceptability of the mechanical pumpdispenser. If the mechanical pump dispenser is acceptable, butwith certain limitations, note accordingly.D663305212. Precision and Bias12.1 Prec
34、isionThe precision is highly dependent on theparticular pump style and contents tested. One laboratory hasinvestigated one particular fine mist pump style and a hairspray product with six replicate tests per temperature variable,yielding no visual product leakage, very minor cloggage, andall specime
35、ns retaining prime. For all specimens evaluated forstrokes to prime, the test yielded an average of 6.58 strokeswith a range of 6 to 7 strokes and a standard deviation of 0.53strokes. For the 23C specimens evaluated for output perstroke, the test yielded an average of 0.136 g with a range of0.130 to
36、 0.142 g and a standard deviation of 0.02 g. For the45C specimens evaluated for output per stroke, the testyielded an average of 0.136 g with a range of 0.131 to 0.142 gand a standard deviation of 0.02 g. Other pumps and contentswill have other averages and will have more or less variabilitybetween
37、replicate tests. Users of this test method are suggestedto reference historical files of previous tests of similar pumpsand contents for an estimate of within laboratory repeatability.The Committee believes that because of this strong product andpump style dependency, further investigation of repeat
38、abilityand reproducibility is not practicable.12.2 BiasThis test method has no bias because an ac-cepted reference or referee value is not available.13.
