ISTA 1A Integrity Testing for Packaged-Products weighing 150 lb (68 kg) or Less

ISTA 1A: Integrity Testing for Packaged-Products Weighing 150 lb (68 kg) or Less

International Safe Transit Association (ISTA) 1A package testing evaluates the performance of a packaged product weighing under 150 pounds. As an ISTA and ISO 17025 certified lab, we realize the importance of integrity testing of packages weighing less than 150lbs. Meeting the ISTA 1A integrity testing requirements can be difficult. We understand the challenges and guide companies through the process.

Keystone Package Testing provides comprehensive reports shortly after completion of the testing. When packages do not meet the requirements, we assist with finding solutions. We are in constant communication throughout the test process. Lastly, Keystone’s proven process helps avoid product launch delays.

Summary of ISTA 1A Integrity Package Compliance

The ISTA 1 series of tests challenges the capabilities of the package and product to withstand transport hazards. Furthermore, the ISTA  1A procedure tests individually-packaged products weighing 150 pounds or less.

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.

Utilizing Keystone Package Testing services during the development phase of a product and package can be helpful for companies. By identifying weak points in a package, there is an opportunity for redesign to correct the issue before it is mass produced. This will save a lot of time and money later on. Keystone engineers will work with you to prevent such issues.

ISTA package testing 1A protocol features preconditioning, vibration, and shock. The preconditioning ensures the product and package are at ambient temperature prior to testing. The ISTA vibration test is at a fixed displacement. The shock test consists of drop, incline impact, or horizontal impact. The ISTA drop test height may vary per package. At Keystone, customers have the benefit of selecting any one of these three shock test methods.

ISTA 1A Simulation Performance Testing Procedures

Unlike some other ISTA standards, ISTA 1A test 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:

Horizontal Impact Impact velocity varies with packaged-product weight

ISTA 1A Accredited Package Testing Facility

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 for package validation.
