This part was proposed by the National Medical Products Administration of People’s Republic of China.
This part is under the jurisdiction of the National Technical Committee 342 on Medical Syringes of Standardization Administration of China.
Introduction
After the packaging system of sterile medical devices has been subjected to all the expected hazards during transportation, whether the performance of the devices delivered to the user still meets the expected performance requirements before delivery is an issue of great concern to the user and is becoming more and more important to manufacturers, users and managers.
This part of YY/T 0681 refers to ASTM D 4169-16 Standard practice for performance testing of shipping containers and systems. The committee concluded that the distribution cycle (referring to DC13 in ASTM D 4169-16) given in Table 1 in this part represents the most severe challenges in the domestic distribution of sterile medical device package and, therefore, is determined as the recommended test procedure for this part. Reference may also be made to the test requirements for other distribution cycles in ASTM D 4169 for sterile medical devices with special distribution cycles.
Test methods for sterile medical device package - Part 15: Performance testing of shipping containers and systems
1 Scope
This part of YY/T 0681 specifies a unified method for evaluating the ability of a sterile medical device shipping unit to withstand the transport environment within a laboratory.
This part is applicable to guidance to the user on the design of an appropriate test plan to subject the shipping unit to a series of anticipated hazards to be experienced during a specific distribution cycle.
This part does not include the performance tests for single parcel transport packages.

3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
?
3.1
acceptance criteria
acceptable quality level that must be met after the shipping unit has been subjected to the test plan
3.2
assurance level
level of test intensity based on its probability of occurring in a typical distribution cycle
Note: assurance Level I is the highest level of test intensity and has a low probability of occurrence, Level III is the lowest level of test intensity but has a correspondingly high probability of occurrence, and the test intensity of Level II is intermediate between Level I and Level III.
3.3
distribution cycle; DC
sequential listing of the test schedules employed to simulate the hazard elements expected to occur for a specific routing of a shipping unit from production to consumption
Note: reference has been made to DC 13 in ASTM D 4169-16 for the distribution cycle given in Table 1.
3.4
feeder aircraft
small, potentially non-pressurized aircraft used to transport express packages
3.5
hazard element
specific event that occurs in a distribution cycle that may pose a hazard to a shipping unit, which will usually be simulated by a single test schedule
3.6
less than truckload; LTL
transport situation in which the cargo is less than one full truckload
3.7
shipping unit
smallest complete unit that will be subjected to the distribution environment, for example, a shipping container and its contents
3.8
porous packaging material
material used in medical package to provide an environmental and biological barrier while allowing sufficient airflow in gas sterilization (e.g., ethylene oxide, steam, gas plasma)
3.9
test plan
specific listing of the test sequence to be followed to simulate the hazards anticipated during the distribution cycle of a shipping unit, including the test intensity and number of test items
3.10
test schedule
specific procedure to be used, including the three assurance level intensities, and a reference to the test method that is the basis of the schedule
Note: the purpose of the test schedule is to simulate the stresses occurring during any hazard element of the distribution cycle.
3.11
single parcel
non-standard shipping unit (e.g. parcels of mailing)
4 Test schedule applicable to distribution cycle of sterile medical device
4.1 The transport tests recommended for the transport package of sterile medical devices shall be conducted in sequence according to the test schedule given in Table 1.
Table 1 Recommended test schedule for shipping unit of sterile medical device
S.N. 1 2 3 4 5 6 7
Schedule A C F I E J A
Item name Manual handling Vehicle stacking Loose load vibration Low pressure Vehicle vibration Concentrated impact Manual handling
Note: reference has been made to ASTM D 4169-16, DC13 for this test schedule. Other distribution cycles may also be selected based on demonstration. Reference may be made to ASTM D 7386 for single parcel transport test.
4.2 The schedule given in Table 1 simulates the various hazards that medical devices are expected to undergo during the transport test. The test schedule is expected to be used for the following:
——used for evaluating the ability of sterile medical device packaging systems (including sterile barriers and protective package) to meet predetermined acceptance criteria after being subjected to the expected transport process.
——serving as a pre-test prior to performance test of a sterile medical device after packaging to evaluate whether the performances of the device in the package still meet the intended clinical requirements after the expected distribution cycle.
4.3 these tests should be performed sequentially on the same shipping unit. For performance tests, this part requires that the shipping unit not be opened until all tests have been completed. If used for other purposes, e.g. package development, the shipping unit may be opened and inspected at various time points in the series of tests, but this may not be able to evaluate the effect of closure on the performance of the container.
