What’s the difference between ISTA 3A and ISTA 6-FEDEX tests?

Date: January 3, 2026Views: 1118

ISTA 3A is a general simulation test for parcel delivery (under 70 kg). ISTA 6-FEDEX is a FedEx-specific protocol that includes unique drop sequences, vibration profiles, and often a over-the-road (OTR) vibration test which is more severe. Your ISTA testing equipment must be capable of programming and executing these distinct, pre-defined profiles.
