Procedure

Identification of Faces, Edges and Corners

Prior to beginning the tests identify the faces, edges and corners according to the procedure below.

Step Action
1 Place the packaged-product in its intended shipping position as determined by shipper. If the shipping position can be variable, place the packaged-product so that the primary shipping label location is on the top face.
2 Does the packaged-product have only six faces (2 sides, 2 ends, top and bottom)?
• If Yes, then go to Step 5.
• If No, continue to next Step.
3 Develop a method to identify each face, edge and corner and document with a diagram.
4 Go to the next Block.
5 Is the package a corrugated container?
• If Yes, continue to next Step.
• If No, then go to Step 8.
6 Does the package have a manufacurer's joint connecting a side and an end face?
• If Yes, continue to next Step.
• If No, then go to Step 8.
7 Turn the packaged-product so that you are looking directly at a face with the manufacturer's joint on the observer's right and go to Step 9.
8 Position one of the smallest width faces of the packaged-product directly in front of you.
9 blank
10 Identify edges using the numbers of the two faces forming that edge.
Example: Edge 1-2 is the edge formed by face 1 and face 2 of the packaged-product.
11 Identify corners using the numbers of the three faces that meet to form that corner.
Example: Corner 2-3-5 is the corner formed by face 2, face 3, and face 5 of the packaged-product.
12 Go to next Block.

Packaged-Product Weight and Size Measurement

You shall know the packaged-products:

• gross weight in pounds (kg) rounded up to a whole number, and

• outside dimensions of Length, Width, and Height (L x W x H) in inches (mm or m).

Before You Begin Vibration Testing

Caution: A restraining device or devices shall be used with the vibration test system to:

• Prevent the test specimen from moving off the platform and

• Maintain test orientation of the packaged-product, but

• The device or devices shall not restrict the vertical motion of the test specimen during the test.

For Fixed Displacement Vibration:

Step Action
1 Familiarity with the following formula is required to calculate
the test duration after the frequency required to bounce the packaged-product is determined in the Vibration Test Block:

Test Duration in Minutes = 14, 200 Vibratory Impacts
Cycles Per Minute (CPM) or
[Cycles Per Second (Hz) x 60]
2 The chart below shows example Test Durations calculated for several frequencies:
blank CPM Hz Test Duration in Minutes
blank 150 2.5 95
blank 180 3.0 79
blank 210 3.5 68
blank 240 4.0 60
blank 270 4.5 53
blank 300 5.0 48

Vibration Test

The table below indicates the steps to perform a Fixed Displacement Vibration Test.

Step Action
1 Put the packaged-product on the vibration table so that face 3 rests on the platform.
2 Start the vibration system to vibrate at 1.0 inches (25 mm) total displacement at the machine's lowest frequency.
3 Maintain a fixed displacement at 1 inch (25 mm) and slowly increase the frequency (speed) of the vibration table until the packaged-product begins to momentarily leave the surface of the platform.
4 Hold the vibration frequency to that determined in Step 3.
5 Can a metal shim be intermittently moved between the bottom of the longest dimension of the packaged-product and the surface of the platform?
• If Yes, hold that frequency and then continue to next Step.
• If No, then increase the frequency until the requirement of Step 5 is met and hold that vibration frequency.
6 Determine the test duration in minutes using the formula indicated in the Before You Begin Block and the CPM or Hz frequency identified in Step 5.
7 Begin the vibration duration.
8 Are you using a vertical linear motion on the vibration system?
• If Yes, then go to Step 12.
• If No, then continue with the next Step.
9 Stop the vibration test halfway throught the vibration duration and perform the appropriate action as indicated below:
• IF a single 90° horizontal rotation is possible, THEN perform a horizontal rotation of 90° as the specimen rests on the platform.
• IF a single 90° horizontal rotation is not practical because of the size of the packaged-product or the stability of the packaged-product, THEN perform a horizontal rotation of 180° as the specimen tests on the platform.
10 Start the vibration system and continue the vibration test at the frequency used in Step 7.
11 Can a metal shim be intermittently moved between the bottom of the longest dimension of the packaged-product and the surface of the platform?
• If Yes, then continue to next Step.
• If No, then slowly increase the frequency until the requirement of Step 11 is met.
12 Complete vibration duration.
13 Inspection of the packaged-product for visible damage is allowed, provided inspection does not alter, in any way, the current condition of the package or the condition or position of the product(s).
14 Vibration testing is now complete. Go to the Shock Test Block.

Before You Begin Shock Testing

The test drop height varies with the weight of the packaged-product. Find the weight of the packaged-product in the following chart to determine a drop height or an equivalent impact velocity to be used for a substituted drop:

Packaged-Product Weight Drop Height Impact Velocity
Equal to or greater than But Less than Free Fall Incline or Horizontal
lb kg lb kg In. mm ft/s m/s
0 0 21 10 30 760 13 3.9
21 10 41 19 24 610 11 3.4
41 19 61 28 18 460 10 3.0
61 28 100 45 12 310 8.0 2.5
100 45 150 68 8 200 6.6 2.0

The test method requires the packaged-product to be dropped in several different package orientations.

A drop test must be performed in all required orientations where dropping the packaged-product is practical.

If dropping in a required orientation is not practical an equivalent incline or horizontal test can be substituted for that orientation.

When using impact velocity, if any test in a Test Sequence is below the required minimum level, that sequence event must be repeated until the test impact velocity meets the minimum.

Shock Test

The table below indicates the steps to perform the Drop Shock Test.

Step Action
1 Determine the method(s) of test and the required drop height or impact velocity in the Before You Begin Block.
2 Do you have a packaged-product with only 6 faces as identified in the Face, Edge and Corner Identification Block?
• If Yes, continue with the next Step.
• If No, then go to Step 6.
3 Test the packaged-product according to the method(s) and level(s) determined in Step 1. Follow the sequence in the table below.
4 Sequence # Orientation Specific face, edge or corner
blank 1 Corner most fragile face-3 corner, if not known, test 2-3-5
blank 2 Edge shortest edge radiating from the corner tested
blank 3 Edge next longest edge radiating from the corner tested
blank 4 Edge longest edge radiating from the corner tested
blank 5 Face one of the smallest faces
blank 6 Face opposite small face
blank 7 Face one of the medium faces
blank 8 Face opposite medium face
blank 9 Face one of the largest faces
blank 10 Face opposite large face
5 All testing is now complete. Go to the Test Report Block.
6 Select a bottom face corner to replace the corner required in Step 4 Sequence 1 to begin the test.
7 Identify the edges of the packaged-product that meet the Step 4 Sequence
2 through 4 requirements.
8 Select any 6 faces to replace the faces required in Step 4 Sequence 5 through 10.
9 Using the corner, edges and faces from Steps 6 through 8 go to Step 3 and proceed.
10 All testing is now complete. Go to the Test Report Block.
