Packages
and products must be evaluated on their ability to withstand hazards
of transportation. DDL shock testing services replicate real-life
shock environments to determine the package or product's level
of fragility.
Shock occurs
to a package or product when there is a change in velocity. When
the package is dropped, the velocity immediately changes inducing
shock.
Test Description
Accelerometers are placed on the critical components of the package.
The package is then dropped from a pre-determined height according
to the ASTM 3332 standard. Drop shock testing assesses how well
the package is protecting the product inside.
Product
Testing
The product is taken through 2 critical parameters (acceleration
and velocity) to assess its fragility.
The product
is subjected to varying degrees of acceleration and velocity.
Acceleration/Velocity is gradually increased by a pre-determined
amount until the product fails.
Package
Testing
Shock testing is performed on a package to determine its fragility
and how well it protects the product. Shock testing results help
the manufacturer re-design the package.
ASTM D 4169 Shock Testing (Practice for Performance Testing
for Shipping Containers and Systems)
Test Description
This method is used to predict the performance of new or redesigned
packages when distributed by any mode of transport. Packages are
subjected to a test plan of anticipated hazard elements (simulated
by an ASTM test method) encountered in the distribution environment.
A series of tests are conducted in sequence with the packaging
unopened for inspection until completion of testing. The package
is then opened and evaluated on its performance. The package will
fail unless both the contents and the package have emerged from
the testing in an acceptable condition according to standardization
criteria.
ISTA 2a Shock Testing (Partial simulation performance test)
Test Description
This method challenges the capability of the package and the product
to withstand transport hazards. It is used on packaged-products
weighing 150 lb (68 kg) or less. ISTA 2a requires that the following
shock testing services be performed:
|
Drop
Shock Testing
height varies with packaged-product weight |
|
|
Alternative
Incline (Conbur)
Impact Velocity varies with packaged-product weight |
|

Horizontal Impact
Impact Velocity varies with packaged-product weight |

Products
The sample size can vary from 3-4 products to 20 - 25 products
(depending on the
value of the product) |
|
|
Packages
Only 1 package is required but we recommend testing 2-3 packages |
