Package testing is an essential requirement for any product being shipped. Both consumer packages and shipping containers have a risk of being dropped or being impacted by other items. Package integrity and product protection are important packaging functions. Tests are conducted to measure the resistance of packages and products to controlled laboratory shock and impact. Testing also determines the effectiveness of package cushioning to isolate fragile products from shock.
Vibration is encountered during shipping (vehicle vibration, rough roads, etc.) and movement on conveyors. The ability of a package to withstand these vibrations and to protect the contents can be measured by several laboratory test procedures. Some allow searching for the particular frequencies of vibration that have potential for damage. Random vibration to better represent complex vibrations measured in field studies of distribution environments.
ISTA shock test is a series of test items specified in its test standards to simulate the shock experienced by packaging during transportation and handling.
CME can supply vibration test system to perform ISTA standard fixed displacement vibration test and random vibration test
CME provides customers with packaging tests in the following mechanical environments: Drop Test, Impact Test, Vibration Test, Compression & Clamping Test.
We can see clearly the different requirements between ISTA 3E and 3H.
Procedure ISTA 3E is a general simulation test for unitized loads of similar retail or institutional packaged-products shipped from a manufacturing location to a distribution center.
