ASTM D6537 Shock Testing
ASTM D6537 package testing covers measured shock for actual or simulated products. As an ISTA and ISO 17025 certified lab, we realize the importance of ASTM D6537 testing. Meeting the ASTM D6537 shock testing requirements can be difficult. We understand the challenges and guide companies through the process.
Keystone Compliance creates an accurate test plan to eliminate expensive over-testing. When packages do not meet the requirements, we assist with finding solutions. Our accurate test reports are delivered quickly. Keystone takes a consultative approach throughout the entire test program.
ASTM D6537 Shock Testing for Determination of Package Performance
The scope of ASTM D6537 covers methods for obtaining measured shock responses using instrumentation for an actual or simulated product package system when subjected to defined shock inputs to measure package performance.
ASTM D6537 package testing establishes methods for obtaining measured shock data for use with shock and impact test methods. It is not intended as a substitute for performance testing of shipping containers and systems such as ASTM D4169.
When testing, an ASTM D6537 package testing lab will address acceleration measuring techniques. Other ways of measuring shock impacts, such as high-speed video, are not covered by this integrity compliance standard.
Shock testing is intended to provide the user with a process to obtain data on package performance when a packaged product is subjected to shock. These measures can be used to quantify or qualify a package system.
Data from this practice may provide a measure of a package’s ability to mitigate the various levels of shipping shock or impact hazards. These measures may be used to prescribe a mode of shipping and handling that will not induce damage to the packaged product or to define the required levels of protection that must be provided by its packaging.
ASTM D6537 Shock Integrity Testing Procedures
ASTM D6537 Sampling and Conditions
Before performing the standard integrity test method, the sampling procedures and specimen to be tested must be determined. It is recommended to test the actual contents and package to evaluate the protective capability intended for shipment. However, use simulated contents to evaluate the package when access to the actual contents is prohibitive because of availability, excessive cost, or hazardous nature.
Condition the package and components to the conditioning requirements by the test method being followed. Unless otherwise specified, conduct all tests with the same conditions prevailing.
ASTM D6537 Test Procedure
First, the accelerometer is mounted at a location on the product that represents the product as a single mass. This location should be rigid and non-flexible. This prevents extraneous responses from being measured, thus distorting or influencing the resulting data.
The mounting of the accelerometer can have a significant effect on the quality of the data. Looseness or loss of contact between the accelerometer and its mounting surface can cause false or spurious readings. The best and most reliable method is a threaded fastening mounted directly to a smooth surface.
Note that the accelerometer is mounted so that its sensitive axis is aligned as accurately as possible with the acceleration direction to be measured.
The sensing orientation of the accelerometer in reference to the axis of the product is documented. When the package is assembled, the accelerometer orientation may not be readily accessible. Necessary connections are made from the accelerometer(s) to the signal conditioner.
The package is assembled by the specimen option chosen and is closed and secured in the same manner as specified for shipment. The shock event is then performed per the established shock and impact method. Where desired and capable, data is saved for further testing and archival purposes.
The ASTM D6537 shock integrity test is repeated as needed to complete the total number of shock impacts per pre-established test sequence.
