1、Designation: D 5094 04Standard Test Methods forGross Leakage of Liquids from Containers with Threaded orLug-Style Closures1This standard is issued under the fixed designation D 5094; 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 (e) indicates an editorial change since the last revision or reapproval.1. Scope1.1 These test methods may demonstrate container/closureintegrity with threaded or lug-style closures by the

3、determina-tion of gross leaks in rigid and semi-rigid containers (up to 4 L(1.06 g). Such tests may be used to indicate the ability of aliquid container to survive the distribution environment with-out leaking. These test methods may not be suitable todetermine the leak resistance of containers inte

4、nded for trans-port of hazardous materials.1.2 Test Methods:1.2.1 Test Method A, Shipping Container Vibration andStorage Test, covers the ability of a shipping container and itsinterior packaging to protect the contents from leakage aftertransportation induced vibration and high-temperature storage.

5、1.2.2 Test Method B, Shipping Container Vibration andVacuum Chamber Test, is suitable for individual containers andis usually less severe than Test Method A. The advantage ofTest Method B is the shortness of the test.1.3 This standard does not purport to address the safetyconserns associated with it

6、s use. It is the responsibility of theuser of this standard to establish appropriate safety and healthpractices and determine the applicability of regulatory limita-tions prior to use.2.

Summary of Test Methods4.1

10、 Method A, Shipping Container Vibration and StorageTestTest specimens are filled to their expected fill capacitywith product or liquid simulating product and the closure isapplied to the container. Closures should be applied with thesame torque as would be encountered in production. Thespecimens are

11、 packed into shipping containers and vibrated.The specimens, stored on their sides, are subjected to 40C(104F) (or other conditions as appropriate) for four weeks.Each specimen is examined for leakage.4.2 Method B, Container Vibration and Vacuum ChamberTestTest specimens are partially filled with pr

12、oduct or liquidsimulating product and the closure is applied to the container.Closures should be applied with the same torque as would beencountered in production. The specimens are packed intoshipping containers and vibrated. Following vibration, theindividual specimens are removed from the shippin

13、g containerand subjected to 10 in. Hg (33.7 kPa) vacuum for 10 min andexamined for leakage.NOTE 1Other levels of vacuum, or time, or both may be appropriate.1This test method is under the jurisdiction of ASTM Committee D10 onPackaging and is the direct responsibility of Subcommittee D10.32 on Consum

Significance and Use5.1 These test methods are used to indicate the integrity ofthe con

16、tainer and closure system in the distribution environ-ment.5.2 These test methods measure the ability of the containerand closure system to prevent leakage when stored or trans-ported upright, inverted, or on the side.5.3 These test methods allow for comparison of container/closure designs of thread

17、ed and lug-style closures of similar ordifferent materials, or different manufacturers. These tests aresuitable for packaging development, engineering and toolingevaluations.6. Apparatus6.1 Method A, Shipping Container Vibration and StorageTest:6.1.1 Drying Oven, constant-temperature, equipped withm

18、eans for ensuring adequate temperature control, 40 6 1C(104 6 1.8F) and air circulation, ambient humidity, or otherconditions as appropriate.6.1.2 Torque Meter, with an appropriate scale which accu-rately measures within the expected torque range.6.1.3 Vibration Test Machine, the apparatus described

19、 in theApparatus section of Methods D 999 may be used.6.2 Method B, Shipping Container Vibration and VacuumTest:6.2.1 Vacuum Chamber, any suitable chamber capable ofwithstanding approximately one atmosphere pressure differen-tial, fitted with a vacuum-tight seal. A vacuum gauge, an inlettube from a

20、source of vacuum, and an outlet tube to theatmosphere shall be sealed to the chamber. The inlet and outlettubes shall be equipped with shut-off valves. The vacuumgauge shall be laboratory quality with a full scale range of 0 to30 in. Hg (0 to 100 kPa).6.2.2 Torque Meter, with an appropriate scale wh

21、ich accu-rately measures within the expected torque range.6.2.3 Vibration Test Machine, the apparatus described in theApparatus section of Methods D 999 may be used.7.

35、nd examine for leakage,cracks, or other visible damage. Record the results of thisexamination. Note location(s) of leakage.12. Interpretation of Results12.1 If there is leakage to the outside of the specimen, thepackage fails the test.12.2 If there is no leakage to the outside of the specimen thepac
