ASTM D6537 Instrumented Package Shock Testing for Determination of Package Performance

ASTM D6537 determines shock responses for product package systems when subjected to shock inputs. As an ISTA and ISO 17025 certified lab, we realize the importance of ASTM shock integrity testing. Meeting the ASTM D6537 requirements can be difficult. We understand the challenges and guide companies through the process.

Keystone Package Testing partners with customers to achieve package compliance. We provide comprehensive reports shortly after the completion of the testing. Keystone creates an accurate test plan to eliminate expensive over-testing.

Summary of ASTM D6537 Shock Testing

The purpose of ASTM D6537 is to measure the shock responses when an actual or simulated package is subjected to shock. This test will measure package performance by using acceleration measurement techniques. Also, ASTM D6537 provides the user with helpful information about package performance. Users can generally determine the package’s ability to withstand shocks and impact hazards that it may encounter throughout distribution.

To fully understand the ASTM D6537 procedure, there is some specific terminology defined by the following:

  • Accelerometer- a sensor that can convert acceleration into a measurable proportional electric signal
  • Coefficient of restitution- rebound velocity to impact velocity ratio
  • Complex waveform- also known as a complex shock pulse; acceleration vs. time graph that represents the response of multiple systems when subjected to an impact
  • Faired acceleration- amplitude that represents the primary response system
  • Fairing- smoothing a recorded pulse by estimating the amplitude of a primary waveform
  • Peak acceleration- maximum absolute value of acceleration (occurring during shock pulse)
  • Primary waveform- acceleration vs. time graph that represents the response of a system when subject to an impact
  • Pulse duration- the amount of time that the shock acceleration is beyond reference level
  • Velocity change- the sum of velocity at impact and rebound velocity

The apparatus required for ASTM D6537 are the shock or impact apparatus, instrumentation system, accelerometer, and cabling. Moreover, apparatuses must meet the requirements outlined in the regulatory standard. Additionally, the amount of samples needed for testing depends on the purpose of the tests.

There are two options:

Option 1- Actual Contents and Package

This test method serves to evaluate the protective capability of the package that is intended for shipment. Prototypes can provide a different outcome so if a prototype must be used, it has to be as close as possible to the actual manufactured package and product.

Option 2- Simulated Contents and Package

Option 2 is available for products that are cost-prohibitive, limited availability, or hazardous. A simulated product may be used but it must have the same characteristics as the actual product.

It is important to maintain structural integrity before testing. The package should not be damaged when it arrives at the testing laboratory.

Before testing, test equipment should be verified through calibration. It is recommended that packaging be conditioned, if applicable, before testing. To begin testing, the accelerometer is mounted on the package in a spot that represents the package as a whole. Furthermore, it is mounted in such a way that it is not loose or does not lose contact with the package.

The recommended mounting method is threaded fastening. However, other methods such as adhesives, cement, magnetic mounts, and waxes can also be used. The package should be closed and sealed in the same manner that it is for shipping. Then, shock testing is performed. After testing, Keystone will write a report that follows ASTM D6537 procedures and outlines the results of the test.
