ISTA 1B Package Testing

ISTA 1B package testing evaluates the performance of a package greater than 150lbs from normal transportation hazards. As an ISTA and ISO 17025 certified lab, we realize the importance of integrity testing. Meeting the ISTA 1B requirements can be difficult. We understand the challenges and guide companies through the process.

Keystone’s proven process helps avoid product launch delays due to communication throughout the test process. We also provide accurate test reports that are delivered quickly. Our pricing is competitive and we offer volume discounts. Lastly, Keystone Package Testing takes pride in having a great reputation of helping customers achieve their package certifications.

ISTA Procedure IB Package Testing is for products weighing over 150 pounds. The test procedure is used to determine the ability of a package to protect the product from normal transportation hazards. This test procedure is for individually-packaged products.

The test sequence of ISTA 1B transit testing includes conditioning, vibration and various types of shock. The conditioning is to ensure the unit is at ambient temperature. Conditioning and preconditioning is performed to simulate the different environments that a package could encounter throughout the distribution channel. The vibration is a fixed displacement vibration. The shock testing includes drop, incline impact, horizontal impact or rotational edge drop. Only one shock test method is to be used. Units do not need to be tested to all three methods. The vibration and shock tests are meant to simulate the different hazards that a package could encounter during distribution.

The drop or impact is to occur on each face or side. The drops are to happen in a certain sequence. The impact test is to occur on four faces. The rotational edge drop involves lifting one edge three to four inches off the ground. That edge of the box is then supported with a timber or support. The other edge is then raised eight inches. The height that it is raised is predetermined by a formula that takes into account the weight of the package.The higher edge is released so that the package drops freely. It is important that it is dropped on a flat and rigid surface.

As with ISTA 1 A testing, only one test unit is required.

ISTA 1B contains three sections:

  • Overview provides the general knowledge required before going into the testing laboratory.
  • Testing presents the specific instructions to do the testing in the laboratory.
  • Report indicates what data shall be recorded to submit a test report to ISTA.
