Inclined Impact Pallet Testing for ISTA 1D Package Testing

ISTA 1D: Package Testing of Packaged Products Weighing Over 150 lb (68 kg)

ISTA 1D testing is an extended procedure that determines the integrity of individually packaged products. As an ISTA and ISO 17025 certified lab, we realize the importance of parcel delivery system shipments and ISTA 1D package testing. Meeting the ISTA 1D simulation integrity testing requirements can be difficult. We understand the challenges and guide companies through the process.

Keystone Package Testing quickly delivers accurate and comprehensive test reports shortly after the completion of the testing. We are in constant communication throughout the test process. Keystone takes a consultative approach throughout the entire test program.

Summary of ISTA 1D Package Integrity Testing for Individually Packaged Products

ISTA 1D is a general simulation performance test that covers the testing of individually packaged products weighing 150 pounds (68 kg) or more when prepared for shipment.

ISTA Series 1 is generally the least strenuous of the ISTA tests. However, when applied correctly, ISTA 1D will provide benefits such as:

  • Shortened packaged development time and confidence in product launch.
  • Protection of products and profits with reduced damage and product loss.
  • Economically-balanced distribution costs.
  • Customer satisfaction and continued business.

Additionally, ISTA 1D testing can be used to compare the relative performance of package and product design alternatives.

ISTA 1D Package Testing Procedures

Note that only one sample is required for this test. The sample should be the untested actual package and product. If this is unavailable, packaging must be as identical as possible.

The ISTA 1D test procedure calls for tests including:

  • Atmospheric Measurement Test Block-Temperature and Humidity.
  • Compression Conditioning Block- Compression.
  • Vibration Test Block-Fixed Displacement.
  • Random Vibration.
  • Shock Test Block-Drop or Impact.
  • Impact and Rotational Drop.

The chart below is from the standard and provides more guidance on the testing procedure and requirements:

ISTA Testing Report

Upon completion of testing, a report is created encompassing the necessary data:

  • Test engineer
  • Date of testing
  • Package failures (if any)
  • Test Results
  • Conditioning

The test report should be submitted to ISTA. If the product and package have met the ISTA requirements, the company will print the ISTA mark on its packaging along with a license number.

This signifies that the package has passed the requirements of the ISTA pre-shipment testing. This package certification is recognized globally. To maintain this certified status, the product must be retested if there are changes to the product, process or package.
