ISTA 1A Package Testing
ISTA Test Procedure 1A was established to test individually-packaged products weighing 150 pounds or less. The ISTA 1 series of tests challenge the capabilities of the package and product to withstand transport hazards. This transit testing procedure is considered an integrity test.
The benefits of ISTA testing are numerous. Package testing promotes customer satisfaction through non-damaged products. It also provides economic benefits or fewer returns and damage claims. Keystone Package Testing assists companies in identifying potential problems before they become actual problems.
ISTA package testing procedure 1A features preconditioning, vibration and shock. The preconditioning is just ensuring the product and package are at ambient temperature prior to testing. The vibration test being fixed displacement. The shock test consists of drop, incline impact or horizontal impact. The customer can select any one of these three shock test methods.
Unlike some other ISTA standards, ISTA 1A only requires one test sample.
ISTA 1A provides the following suggestions:
- To use random vibration instead of fixed displacement vibration, use ISTA Test Procedure 1G.
- For packaged-products where a minimum compression value should be tested, use ISTA 1C.
- For packaged-products intended for international distribution, consider ISTA 2A.
- For packaged-products that may be transported in a small parcel delivery system, consider ISTA 3A.
The chart below is from the standard and provides more guidance on the testing procedure and requirements:
|Sequence #||Test Category||Test Type||Test Level||For ISTA Certification|
|1||Atmospheric Preconditioning||Temperature and Humidity||Ambient||Required|
|2||Vibration||Fixed Displacement||1in (25mm) peak-to-peak at a frequency to be determined||Required|
|3||Shock (alternative methods allowed – select one test type)||Drop||Height varies with packaged-product weight||Required|
|Inclined Impact (Conbur)||Impact velocity varies with packaged-product weight|
|Horizontal Impact||Impact velocity varies with packaged-product weight|
What can one gather from the results of ISTA 1A packaging testing? The results provide an evaluation of the performance of the packaged-product. This evaluation can be used to compare alternative package designs. It can also be used to compare various packaging materials.
