Shock and Fragility Testing | Product Durability Test
Products must be evaluated for their ability to withstand hazards of transportation.
DDL shock testing services replicate real-life shock environments to determine the product’s level of fragility.
Shock occurs to a product when there is a change in velocity. When the package is dropped, the velocity immediately changes, therefore inducing shock.
During shock testing, accelerometers are placed on the critical components of the product. The test specimen is then dropped from a pre-determined height according to the ASTM Standard D3332
. Drop shock testing assesses the fragility and durability of the product.  The product is evaluated using two critical parameters, acceleration and velocity, to assess its fragility. Shock intensity is gradually increased by a pre-determined amount until the product fails. The sample size varies widely for shock testing, as few as three (3) or four (4) can be used for high value products or as many as twenty (20) to twenty-five (25) products may be tested for lower value products.
DDL has the capability to perform shock testing up to 600G’s and as short as a two (2) millisecond pulse for a half-sine shock pulse.
DDL performs many custom tests and protocols for shock testing as well as industry standard test methods like those shown below:
| ASTM D2463 |
Drop Impact Resistance of Blow-Molded Thermoplastic Containers

| ASTM D3332 |
