Summary of ISTA 2C Integrity Testing

ISTA Testing Procedure 2C outlines the necessary package testing for furniture packaging. Specifically, this procedure covers testing of individually packaged products of furniture (case goods) for shipment.

When this ISTA Series 2 test is applied correctly, testing will provide benefits such as:

  • Shortened package development time and confidence in product launch
  • Protection of products, reduced damaged and reduced product loss
  • Economically balanced distribution costs

Although the traditional furniture definition of case goods is for hard goods and upholstered furniture, ISTA 2C testing can also be used for any furniture transported in a container.

ISTA 2C Package Integrity Testing Procedures

Transit testing for this procedure involves the main test sequences below.


First, atmospheric preconditioning. The package must be soaked at ambient room temperature for at least 12 hours before testing must commence.

The next test sequence is atmospheric conditioning, which is optional but recommended. During this sequence, the package is subjected to one or more of a variety of conditions.

These conditions include extreme cold temperatures, extremely hot temperatures, high humidity, and low humidity. There are also suggested conditions that change from one range to another. The typical soak time for the conditioning is 72 hours. The objective of this testing is to identify the package’s performance at anticipated atmospheric limits. This will provide the seller with insight into how crucial these extremes will be to furniture packaging.


The next test sequence in ISTA 2C testing is vibration testing. This test sequence requires random testing under a dynamic load. The top-load simulates freight on top of a floor-loaded shipping unit in a 108-inch trailer.

There are three levels of top-load test levels. Level one is 12 pounds per foot cubed. Level two is 10 pounds per foot cubed. Level three is eight pounds per foot cubed. The level three method assumes that the carrier uses air-ride trucks. There are several requirements for the top load. It must be larger than the test specimen. However, it must not overhang the specimen by more than one and a half inches. It must also spread the weight out evenly across the entire test unit.


The final test sequence is shock testing. The shipper will have the ability to select a method of shock testing from one of three different choices. The first available method is drop testing. The second method is inclined impact testing. The final available method is horizontal impact testing.

Test Report

Upon completion of the ISTA 2C testing, the shipper will receive a test report. That test report will include the results of the testing and photos of the packaged product before and after each test. This test report will be submitted by the shipper to ISTA. ISTA will review the report and issues transit tested package certification or an acknowledgment.
