ISTA 2A Package Testing
ISTA 2A is designed for advanced testing of packaged products weighing 150 pounds or less. As an ISTA and ISO 17025 certified lab, we realize the importance of partial simulation testing. Meeting the ISTA 2A requirements can be difficult. We understand the challenges and guide companies through the process.
When packages do not meet the requirements, we assist with finding solutions. Keystone Package Testing creates an accurate test plan to eliminate expensive over-testing. Likewise, Keystone takes a consultative approach throughout the entire test program. We have a reputation for helping customers achieve their package certifications.
Summary of ISTA 2A Transit Compliance 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 for this procedure.
The ISTA 2 series of standards combine 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.
Aftershock 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:
|Sequence #||Test Category||Test Type||For ISTA Certification|
|1||Atmospheric Preconditioning||Temperature and Humidity||Required|
|2||Atmospheric conditioning||Controlled Temperature and Humidity||Required|
|3||Compression (Alternative methods allowed-select one test type)||Machine Apply and Release/Machine Apply and Hold/Weight and Load Spreader||Required|
|4||Vibration (alternative methods allowed-select one test type)||Fixed Displacement/Random||Required|
|5||Shock (alternative methods allowed-select one test type)||Drop/Incline Impact (conbur)/Horizontal Impact||Required|
|6||Vibration (alternative methods allowed-select one test type)||Random Fixed Displacement/||Required|
