SAMPLE REPORT
The following is a sample of the typical final written report prepared
and submitted by any CTL Laboratory. Each report is professional
in layout, artwork and presentation format. It is typically detailed
in nature and will address the client's specific requirements. The
timeline for conducting each test required varies. Therefore it
is difficult to state specifically how long each test will take
to conduct. However, as a general rule of thumb, from the time CTL,
receives the order for a test until the date the final report is
presented to the client is an average of 1-10 workdays.

RE: ISTA Test Performance of 6 PC Keri 33% Moore Shipper
P.O. #13951Z; BMS OPR #6819/6820
CTL P. #40640-A; ISTA LABORATORY ID: ST-2013
Pursuant to your recent request, CTL has performed the International Safe Transit
Association (ISTA) Project 1A test cycle on one (1) 6 PC Keri 33% Moore Shipper submitted
to this laboratory on June 23, 2003. Upon receipt, the prepackaged load is inspected and,
thereafter, subjected to vibration and drop testing in accordance with ISTA test protocol,
followed by top to bottom dynamic compression.
Inner Packaging:
- Six (6) Keri brand Dry Skin Lotion filled oval shaped plastic bottles
with dispensing pumps, each having Net Wt. of 20 Oz. (567 grams), arranged 3 X 1 within
the inner cartons.
Outer Packaging:
- Style - Regular Slotted Container
Manufacturer - Not indicated
Size (OD) - 8-1/4" x 6-3/4" x 10-1/4"
Corrugation - Vertical "C" flute, Kraft/Kraft
Mfr's joint(s) - One (1) tab is glued inside
ID - 6 PC Keri 33% Moore; OPR #6819/6820
Gross Weight - 9.4 lbs.
Closure - 2" plastic tape: One (1) piece on each top and bottom flap seam
Outer Packaging Details:
- Top Pad - 1 required
Material - Kraft/Kraft "C" flute corrugate
Size (OD) - 7-5/8" x 6"
One plain pad is placed on top of the inner packagings
- Inner Carton - 2 required
Material - Kraft/Kraft Paperboard
Size (OD) - 6" x 3-13/16" x 9-9/16"
Each carton contains three (3) product bottles.
- VIBRATION TEST
With the shipper placed on the vibration table in its normal
shipping orientation, it is vibrated at a frequency of 230 CPM
(+1G) for a period of 62 minutes which results in a total of
14,200 vibratory impacts. After the first 31 minutes of the
vibration, the shipper is rotated 90 degrees for the final 31
minutes of testing.
- FREE FALL DROP TEST
Following the vibration test, the shipper is subjected to ten
(10) free fall drops from a height of 30" onto the following
box parts:
| 1st Drop |
Bottom manufacturer's joint corner
|
| 2nd Drop |
Shortest edge radiating from the corner of the 1st drop
|
| 3rd Drop |
Next shortest edge radiating from the corner of the 1st
drop
|
| 4th Drop |
Longest edge radiating from the corner of the 1st drop
|
| 5th Drop |
Flat onto one of the smallest panels
|
| 6th Drop |
Flat onto the opposite small panel
|
| 7th Drop |
Flat onto one of the medium panels
|
| 8th Drop |
Flat onto the opposite medium panel
|
| 9th Drop |
Flat onto one of the largest panels
|
| 10th Drop |
Flat onto the opposite largest panel
|
- DYNAMIC COMPRESSION
With the shipper placed on the bottom platen of the compression
machine in a side orientation, a dynamic load is applied at
the rate of 1/2" per minute. The unit is compressed in this
manner until the maximum load is sustained.
Dynamic Compression Test Results:
| DEFLETION (IN) |
LOAD (LBS) |
| 0.10 |
50 |
| 0.20 |
150 |
| 0.40 |
375 |
| 0.60 |
725 |
| 0.80 |
825 |
| 0.84 |
870* |
* - Maximum Load (ML) sustained
Using the following formulae and indicated values:
SAFE STACKING LOAD (SSL) = ML x 0.85 / SF
| Where: |
0.85 is the statistical variation |
| |
SF is the safety factor. |
SAFE STACK HEIGHT (SSH) = (SSL / GW) + 1
| Where: |
GW is the gross weight of 1 unit (= 9.4 lbs.) |
SAFE STACK HEIGHT (SSH) (INCHES) = BH * SSH (UNITS)
| Where: |
BH is the box height as stacked (= 10.25 inches) |
Hence:
| SAFETY FACTOR |
3 |
4.5 |
8 |
| SSL (LBS) |
246 |
164 |
92 |
| SSH (UNITS) |
27 |
18 |
10 |
| SSH (INCHES) |
276.75 |
184.5 |
102.5 |
Based on the test results recorded for compression testing,
if the shipper is palletized, we conclude that the most the
shipper will sustain is a stack of 26 units on top, or a total
of 27 carton stack for SF = 3, a stack of 17 units on top, or
a total of 18 carton stack for SF = 4.5, and a stack of 9 units
on top, or a total of 10 carton stack for SF = 8.
Detailed inspection of the Shipper following the completion of the test cycle
uncovered that one bottle had the dispensing cap ring broken resulting in the product leakage
Based on the test results presented herein, we submit that the 6 PC Keri 20 Oz. 33% More
Shipper as received and tested, does not satisfy the ISTA test criteria and it is not capable
of further handling.
