Precautions5.1 Appropriate handling considerations should be given to flammable, toxic, c

16、austic, or other potentially hazardous materialused. When testing at any temperature, safety should be the number one consideration and special attention should be used on theflash points of the products tested.6. Sampling6.1 Based upon the desired precision, sampling shall be performed in accordanc

17、e with Practice E122.6.2 In the absence of any special sampling plan, performance shall be based on not less than the number of representativespecimens exposed to any of the environmental conditions as specified in Section 9.7. Test Specimens7.1 Test specimens shall be clean, dry, and previously unu

18、sed mechanical pump dispensers.8. Conditioning8.1 If possible, condition the test specimens at 23 6 3C (73 6 5.4F) for not less than 4 h. If the test specimens are notconditioned at the recommended temperature and humidity, this should be noted in the test report discussed in section 11.1.8.2 Test p

19、umps should be tested no sooner than 24 h after assembly when possible. If pumps are not conditioned at therecommended time, this should be noted in the test report discussed in 11.1.9. Test Specimen Preparation9.1 Prepare a minimum of twelve unprimed mechanical pump dispensers with product and cont

20、ainers to be used for evaluation.9.1.1 Label all of the assembled units with the product name, any safety hazards for the product, name of the techniciancompleting the test, and the test number or means of identifying the test along with the following :9.1.1.1 Minimum three units labeled, “Upright,

21、Ambient.”9.1.1.2 Minimum three units labeled, “Upright, Oven 45C”9.1.1.3 OptionalMinimum three units labeled, “Upright, Cycle Chamber.”9.1.1.4 Minimum three units labeled, “On-Side, Ambient.”9.1.1.5 Minimum three units labeled, “On-Side, Oven (45C).”9.1.1.6 OptionalMinimum three units labeled “On-Si

22、de, Cycle Chamber.”NOTE 3Since the output of this test is weight loss of product for the total package of container with a mechanical pump dispenser, it may beadvantages for a control package of the test container with a standard closure to be included at each condition so that the effect of the mec

23、hanical pumpdispenser may be determined.10. Procedure10.1 If the data is to be presented as gross weight lost only, then proceed to 10.2. If the data is to be presented as weight lostas a percentage of the weight of the product, weigh each container with its intended pump at the beginning of testing

24、 and recordthat data on the data sheet as “Unfilled Packaging Weight.” (Tare).10.2 Fill each container with the desired amount of product. The level of product in the container should represent the level usedfor commercial use. To better identify leakage, food coloring or dye may be added.10.3 Affix

25、 the mechanical pump dispensers to each container securely to prevent leakage between the container at the minimumrecommended torque load in accordance with Test Method D2063.NOTE 4It is extremely important that the test specimens exhibit the minimal recommended torque load so that the worst case fo

26、r detecting leakageis observed.10.4 Weigh each package and record the “initial weight” data (Wi) on a data sheet with the information identifying the package.10.5 Place all of the test specimens, as prepared in 9.1 in their respective environments as indicated by the appropriate labelon each unit. S

27、pecimens labeled “On-Side” should be placed with the orifice facing down excluding trigger sprayers. Triggersprayers may have the orifice to the side. If the mechanical pump dispensers use a protective hood or overcap, these test specimensshould be stored without these protective devices in place. I

28、f the mechanical pump dispensers have a locking feature, these testspecimens should be in the locked position during storage and the unlocked position during inspection and testing.10.6 Once a week for a period of four weeks, (generally on the same day of the week as the test start day), remove all

29、of thetest specimens from their respective environments and inspect the test specimens for leakage.D6654 18210.7 Allow the temperature of the test specimens to equilibrate (generally 4-6 h) to ambient temperature prior to the actualevaluations.10.8 Weigh each package and record the “new weight” data

41、2 Report the overall results of the testing and draw a conclusion as to the acceptability of the mechanical pump dispenser.If the mechanical pump dispenser is acceptable, but with certain limitations, note accordingly.12. Precision and Bias12.1 PrecisionThe precision of this test method practice is

42、highly dependent on the particular pump style and contents tested.One laboratory has investigated one particular pump style and a hairspray product with 12 replicate tests for gross weight loss only,yielding no visual product leakage along with the results provided in Table 1.12.1.1 Other pumps and

43、contents will have other averages and will have more or less variability between replicate tests. Usersof this test method practice are suggested to reference historical files of previous tests of similar pumps and contents for an estimateof within laboratory repeatability. Committee D10 believes th

44、at because of this strong product and pump style dependency, furtherinvestigation of repeatability and reproducibility is not practicable. For the precision and bias for strokes-to-prime andoutput-per-stroke data, the user should refer to test methodsTest Methods D3890 and D4336.12.2 BiasThis test m

45、ethod practice has no bias because an accepted reference or referee value is not available.13.
