ISTA 2A Package Testing
ISTA Procedure 2A shipping testing is designed for packaged-products weighing 150 pounds or less. Products that are individually-packaged on a skid or pallet that weigh more than 100 pounds should not be tested to this procedure.
The ISTA 2 series of standards combines basic test elements of ISTA series 1 with advanced test elements from the ISTA 3 series.
The test sequence of ISTA 2A includes atmospheric preconditioning, which is essentially a soak at ambient room temperature for six hours. The next step is atmospheric conditioning. This involves a controlled temperature and humidity for a specified duration. Most of the test durations are 72 hours.
Once the ISTA 2A conditioning test is completed, the package is compressed. There are three options available. The first is machine apply and release. The second is machine apply and hold. The third is the use of a weight and load spreader.
Following the ISTA 2A compression testing the package will undergo vibration testing. Like compression, sellers have a choice between methods. One method is fixed displacement vibration. The other method is random vibration.
Once vibration testing is complete, the next step is shock testing. Shock testing offers three methods, of which one must be selected. The first available method is drop.
The next method is incline impact. The third method is horizontal impact. The ISTA 2A test drop height will vary with the weight of the packaged product. This applies to all three of the shock test methods.
After shock testing is another round of vibration testing. It is important to note that the vibration testing in sequence six does not have to match the vibration test method used in sequence four. The methods can match or be different. It is completely up to the seller as to what methods are selected. The vibration testing is completed on four faces of the package. The vibration test duration varies on the face being tested, but ranges from 10 minutes to 30 minutes.
Included below is a summary of the various test sequences for ISTA 2A transit testing package validation:
