5.0Procedure

5.1Common Tasks and Test Plan Selection

5.1.1Results from each module/test-step must be recorded using the attached"Packaging Qualification Test Report Template"(see Section

6.0).

5.1.2Modules within a test plan must be performed in the order as listed within that test plan.Product under test must also not be subjected to

undue handling or transportation-all tests must be conducted within a single test facility and within the required amount of time to ensure

temperature stability has been maintained(see Section5.1.3).

5.1.3In preperation for performing a test plan,packaged products must be conditioned to laboratory standard conditions for6hours or until

equilibrium is achieved.

Temperature:73.4+/-2degrees F(23+/-1degrees C)

Relative Humidity:50+/-2%

Reference ASTM D-4169Section6.1.1:

"Conduct the test at standard conditions and compensate for the effects of any climatic condition.Condition the

shipping units to a standard atmosphere of73.4+/-2°F(23+/-1°C)and50+/-2%relative humidity."

5.1.3.1Tests should be conducted in the conditioned atmosphere whenever possible.If not possible,testing must be conducted immediately

after removal from the conditioning environment and completed within10-hours.It tests are not completed within10-hours,

conditioning to laboratory standard conditions must be reapplied before testing can continue.

5.1.3.2OPTIONAL-"Climate"Conditioning

Use"climate"conditioning only when special circumstances require it-such as if new shipping materials have been introduced and no

prior test history exists;unexpected failures have been observed with packaging and additional testing is needed;or the test has been

specifically requested by Product Quality or Packaging Engineering.

Reference ASTM D4169,Section6,"Conditioning"

Insure static conditioning is complete prior to starting climate conditioning.

●

If testing products made of SBS materials with glue flaps,check to see if glue flaps remained intact during conditioning before ●

proceeding to compression test.Maximum glue flap departure allowable is5%.i.e.if20units(40glue flaps)tested,

maximum of2flaps departure,would be acceptable.Replace"failed flap"units with units that pass conditioning and proceed

to compression test.

Units under test are to be conditioned as follows:

●

Condition Temperature Humidity Duration

Lab Ambient(Typ)20o C±2o C(68o F±4o F)50%RH±5%6hours(±15mins)

Tropical(Wet)38o C±2o C(100o F±4o F)75%RH±5%24hours(±15mins)

Desert(Dry)60o C±2o C(140o F±4o F)20%RH±5%6hours(±15mins)

Unless otherwise noted,all remaining tests are then to be performed at Lab Standard conditions(see section5.1.3and5.1.3.1)●

and as soon after removal from conditioning as is practical.Record conditions and durations obtained for conditioning and all

remaining tests.

5.1.4Prior to any test being performed,and regardless of the test plan selected,at DVT(Design Verification Testing)phase all packages

must undergo a"Measurement Audit"as described in section5.7

5.1.5Following the completion of the selected test plan,cosmetic and functional inspection of the package contents must be performed.

See Section4.1for acceptance criteria.

5.2Test Plan A

5.2.1Ensure all common tasks as defined in sections5.1.1-5.1.5are understood and performed.

5.2.2Drop Test#1(Initial-Manual Handling):

5.2.2.1Reference ASTM D-4169,Section10,Schedule A,Assurance Level II,and select drop height based on shipping weight as shown

5.2.2.2

5.2.3Compression Test-Static:

5.2.3.1Reference ASTM D4169,Section11,Schedule-B,"Warehouse Stacking"

5.2.3.2Tests are to be performed based on ASTM Section11.3,"Warehouse&Vehicle Stacking made up of identical shipping units".

Load values are are to be determined using the formula listed therein and is given below.

5.2.3.3Calculate the Load,L,according to the following formula:

L=M*J*[(H–h)/h]*F

Where,

L=computed load,N or lbf

J=9.8N/kg or1lbf/lb

M=mass of one shipping unit,kg or lb

H=maximum stack height,2.7m or108in.

h=package height,m or in.

F=factor=4.5

5.2.4Vibration Test-Random#1(Initial-Vehicle):

5.2.4.1Reference ISTA3A–Over-the-Road Trailer Spectrum,modified to reduce required test system displacement.Set the PSD level

Grms level of0.519.

5.2.4.2Test duration=270minutes.

5.2.4.3Orientation shall be top-bottom on the dominant shipping axis.

5.2.4.4Top load the Unit Under Test according to the formula shown below.The load should be+/-5%of the calculated value.

L=((Int(V/H)–1)*M)/sqrt(5)

Where,

V=Vehicle height=2.2m or86.6”

H=Package height

M=Package weight

sqrt(5)=2.236

Int()=Integer value(decimal deleted)

5.2.4.5Use a top load apparatus,an example of which is shown in Appendix B.

5.2.5Vibration Test-Random#2(Final-Vehicle):

5.2.5.1Reference ISTA1G.Set the PSD level for each of the following frequency break points shown in the table below with overall

5.2.5.2Total Test duration=50minutes.

5.2.5.3Orientation shall be top-bottom on the dominant shipping axis for the first half of the test time.The remaining test time shall be

split evenly for orientation on each of the other two axes.

5.2.6Drop Test#2(Final-Manual Handling):

5.2.

6.1Reference ASTM D-4169,Section10,Schedule A,Assurance Level II,and select drop height based on shipping weight as shown

5.2.

6.2document for orientation.

A.Identification of Box Faces&Edges

Reference:ISTA3A

B.Top-Load Apparatus

Reference:ISTA3A

The Top-Load Apparatus for Standard,Small,Flat and Elongated package-types shall be:(see Figure1for example of Top-Load Apparatus)

A fiberboard box,or other container,of sufficient strength and ability to hold a load spreader(such as a3/4"piece of plywood or a plate of

●

steel that's the same length and width as the inside dimensions of the load apparatus)and required weight for each axis and

The face dimensions of the Top-Load package which will be applied to the test specimen shall not be shorter than the two dimensions of the ●

test specimen’s top face when positioned for testing,but

The face dimensions may be longer by100mm(4in)than the two dimensions of the test specimen’s top face when positioned for testing and ●

Some means of adding additional weight so that the Top-Load(TL)is distributed evenly over the entire inside face area of the Top-Load ●

apparatus that will apply the Top-Load to the top face of the test specimen when it’s positioned for testing and

Adequate void fill that shall securely hold the weight in place to prevent the weight from moving or bouncing within the top-load apparatus ●

(it is also recommended to use stretch wrap around the test specimen and the top-load apparatus to prevent the topload apparatus from

bouncing on top of the test specimen)and

The combined weight of the Top-Load apparatus shall equal the Top-Load weight,±three percent(3%)as determined in the table in5.5.4.4.
