Is ISTA 2A more restricted than ISTA 3A? Which one is higher standard?
I want to know if ISTA 2A is more restricted than ISTA 3A or not. Which one is higher standard than the other?
ISTA 2A is a 2-Series partial simulation performance test. 2-Series tests contain at least one element of 3-Series type General Simulation performance tests, such as atmospheric conditioning or mode-shaped random vibration and at least one element of a 1-Series type non-simulation integrity test.
ISTA 3A is a 3-Series general simulation performance test for parcel delivery system shipments of 150 lbs. or less. 3-Series tests are designed to provide a laboratory simulation of the damage-producing forces and conditions of transport environments. These tests are applicable across broad sets of circumstances, such as a variety of vehicle types and routes, or a varying number of handling exposures. Characteristics will include simple shaped random vibration, different drop heights applied to the sample package, and/or atmospheric conditioning such as tropical wet or winter/frozen.
