ISTA 1D
Extended Testing for Packaged Products Weighing Over 150 lbs (68 kg)
ISTA 1D is an extended test for packaged products over 150 LB (68 KG). It is a more sophisticated test method than ISTA 1B. However, this test should still be viewed as s a screening test. Micom offers ISTA 1D testing as part of its Package testing services.
Uses and Factors to Be Considered for ISTA 1D
ISTA 1D is an integrity test for individually packaged products weighing over 150 lbs (68 kg). It can be used to evaluate the performance of a packaged product and compare the relative performance of package and product design alternatives. The package and product are considered together and not separately. They both need to be tested together. ISTA 1D does not cover specific conditions than can occur during transit such as moisture, pressure or unusual handling. If you need to test to these distribution hazards, we recommend you test to ISTA Series 2 and ISTA Series 3 tests instead.
ISTA standards require a minimum of 1 sample to be tested. However, for final packaging design purposes a higher number of samples, such as 5 or more, is recommended. Nonetheless, testing only one is mandatory. Alternatively, the ASTM D4169 standard can be used to test your packages.
Please note that packages that have already been subjected to the rigors of transportation prior to the test cannot be assumed to represent standard conditions. In order to ensure testing in optimal condition, products and packages shipped to accredited laboratories for testing must be over-packaged for shipment to the laboratory or repackaged in new packaging at the laboratory.
ISTA 1D Test Sequence
The tests shall be performed on each test sample in the sequence indicated in the following table
| Sequence No. | Test Category | Test Type | Test Level | For ISTA Certification |
| 1 | Compression Conditioning | Machine or Static | Calculated Test Load or Force | Required |
| 2 | Vibration
(Alternative methods allowed – select one test type) |
Fixed Displacement | 1 in (25 mm) peak to peak at a frequency to be determined | Required |
| Random | Overall Grms level of 1.15 | |||
| 3 | Shock
(Alternative methods allowed – select one test type) |
Drop | 6 in (150 mm) | Required |
| Incline Impact (Conbur) | 69 in (1.7 m) per second impact velocity | |||
| Horizontal Impact | 69 in (1.7 m) per second velocity change | |||
| 4 | Shock | Rotational Edge Drop | 8 in (200 mm) | Required when not testing face 1 |
