Shock testing can help determine a products or packaging system’s level of fragility by measuring the amount of input acceleration required to damage the product’s function or cosmetics. The product is evaluated by controlling two critical input parameters – acceleration and velocity.
DDL can perform shock testing up to 600 G’s of force with a capacity (payload) of 1000 lbs. By controlling the acceleration and corresponding duration of the nominal pulse, we meet the requirements of many of the industry standards in shock testing. We also are able to customize these parameters to meet any custom requirements that are needed.
We can perform half-sine drops and trapezoidal drops. These drops can have a duration from 2 ms all the way to 70 ms. The maximum height we can perform a drop from on this system is 40 inches. Our shock table is 36 inches by 42 inches with mounting holes every 6 inches. With in-house fixture creation, we can accommodate shippers and parts of any shape and size.
DDL performs shock testing to the following standards:
ASTM D3332 is one of the test methods used to evaluate a product’s ability to withstand hazards associated with high intensity impact inputs. This test is used to help in the design of shipping containers for transporting the products, as well as to improve product ruggedness. There are two test methods with this standard. Test Method A is used first to determine the product’s critical velocity change. Test Method B is then used to determine the product’s critical acceleration.
MIL-STD 810 is the Department of Defense test method used to evaluate a products ability to withstand various environmental conditions a product could be exposed to. Section 516.8 of this standard calls out all of the different requirements a sample must withstand when it comes to shocks. Each of these requirements simulate conditions the test sample may see when being used over its lifetime. The standard defines 6 different shock methods. DDL can conduct Free Fall Drop testing, Half-sine and Trapezoidal testing that is needed for the different procedures.
IEC 60068-2-27 is the standard from the International Electrotechnical Commission that defines shock testing. Both half-sine and trapezoidal shocks ranging from 5 g of force to 500 g of force can be performed per this standard. The most commonly requested shock acceleration and duration from this standard is the acceleration is set such that it will produce 100 g of force with a 2 ms duration half-sine pulse.
Other common standards that DDL can run shock testing to include: EN 45502, ASTM D5487, ISO 11608-4 and IEC 60721-3-7.
