Moving to ocean and rail freight from airfreight
We current ship our medical devices via truck and airfreight to our customers worldwide. They are packaged in timber crates and weigh between 100 - 450kg's.
We want to send these devices by cargo sea freight, there is also the possibility that rail freight might also be involved in the distribution chain.
Our current testing to date is:
Elements of ISTA 2B - Random vibration (Truck & Air II for 90 min each), vertical shock (drop) testing, edge drop testing as well as cold, hot and tropical climate testing.
Is there any additional testing you would recommend to reduce the risk of product damage?
Current thinking is that in general no special tests or additional test elements are required for ocean shipment. ISTA Procedures and other industry-standard packaging test protocols don't contain PSD profiles for ocean shipment. This is because numerous studies have shown that vibration during sea transport is so small its negligible. It is accepted that the shock portions of ISTA Procedures (drop and impact tests) generally cover the shocks encountered in ocean transport: loading/unloading, cargo shifting due to waves and heavy seas, etc. So my recommendation would be to select an appropriate test as if the packaged-product were going to be surface-transported only. That will cover to/from the port while enveloping the hazards of ocean shipment. If you think your dockside loading/unloading might be more severe than other types of handling you could increase the impact velocities and drop heights found within the current procedures. You could also add a flat drop (to simulate handling with cargo nets), and perhaps rotational corner drops as well. These “increases” would help encompass the typical pitch/roll/yaw hazards that might be encountered.
If possible, I would recommend you use a general simulation test as opposed to the partial simulation testing you currently use. Please contact me directly for more information on which test procedure might be the best fit for your current distribution environment.
