Packaged Products for Parcel Delivery System Shipment 150 lbs (68 kg) or Less
ISTA 3A tests packaged products for parcel delivery system shipment weighing 150 lbs or less. This test is used to simulate courier companies’ shipping environments. ISTA 3A is often required by .COM retailers.
Micom offers ISTA 3A testing as part of its Package testing services. Alternatively, the ASTM D4169 can also be considered.
ISTA 3A Uses and Factors to Be considered
ISTA 3A is a general simulation test for individually packaged products that will challenge the capability of the package and products to withstand distribution hazards in the small parcel delivery system. Packages to be tested to that standard must weigh less than 150 lbs. This test separates packages by shape into four categories. The four shapes are standard, small, flat and elongated. The tests and the test conditions change as a function of the package shape. While testing to ISTA 3A, the package and product are considered together and not separately, i.e.: they both need to be tested together. Test samples can be tested under specific atmospheric transit conditions such as moisture, low temperature or low pressure (simulating altitude). Should you have any questions or need help please contact our material testing lab. Our test experts will be happy to work with you to tailor the best possible packaging test plan for your needs.
ISTA 3A requires a minimum of 1 sample to be tested. For final packaging design purposes a higher number of samples is recommended; ideally 5 or more. However only testing one is mandatory to establish compliance.
The tests shall be performed on each test sample in the sequence indicated in the following table:
ISTA 3A – Standard Packaged Product Test
|Sequence #||Test Category||Test Type||Test Level||For ISTA Certification|
TEST BLOCK 1
|Temperature and humidity||Ambient||Required|
TEST BLOCK 1
|Controlled temperature and humidity||Temperature and humidity chosen from chart||Optional|
TEST BLOCK 3
|Drop||9 drops – height varies with packaged-product weight||Required|
TEST BLOCKS 4 & 7 for Standard
TEST BLOCKS 5 & 7 for Pails and Short Cylinders
|Random with and without top load||Overall Gmrs levels of 0.53 and 0.46||Required|
TEST BLOCKS 2 & 6
|Random Vibration Under Low Pressure||Truck or Truck & Air dependent||Optional|
TEST BLOCK 9
|Drop||8 drops – height varies with packaged-product weight. Includes drop on hazard||Required|
The table above is for standard size packages. As outlined above, it will change as a function of the package shape.
Typical Experimental Parameters
Number of specimens/product: 1 (min.) Maximum sample weight: 150 lbs
The video below shows drop test #3 of the ISTA 3A standard. This test includes 9 drops with a set height based on the weight of the package.
