For constant load test refer to Test Method D Link to Active This link will always route to the current Active version of the standard. Also, unit loads are generally tested only in the top-to-bottom orientation. Planar Biaxial Testing Guide.

ASTM D may be asttm for measuring the ability of the container d624 resist external compressive loads applied to its faces, to diagonally opposite d624, or to corners. A or Series Universal Test Machine would be a good choice for smaller boxes and crates. Standard load ratings up to kN 67, lbf ; higher ratings available upon request Platen diameters available from 56 mm to mm 2. Speak with one of our fixture specialists to learn more about our compression platens.

Specimens for ASTM D should be the full shipping container prepared in the same way that it will be used for packing and shipping.

We’re ready to help! Have a question about conducting the test for this standard? This is a general guide designed to help you understand the basic test procedure and equipment needed to test your products and materials to this standard. Contact our Engineers Today! How to Build a New Test. Shipping containers may be tested with or without contents. We offer machines, apparatus, testers, tensile grips, test fixtures, clamps, holders, jigs, faces, jaws, extensometers, environmental and humidity chambers, furnaces, baths and custom solutions for unique applications.

ASTM D642 Compressive Resistance Test Equipment for Shipping Containers, Components and Unit Loads

The Series Universal Test Machine is a common choice for this standard, and specifically the Family are best for wide column spacing for large boxes, crates and pallets. ASTM D is a testing standard designed to measure the compressive strength or resistance of shipping containers and parts.

Compressive resistance is one of the properties used to evaluate the ability of shipping containers, components, and unit loads to successfully survive the compressive forces they d6442 subjected to during storage and distribution. Fixed-platen machines generally cause corrugated box specimens to fail at their strongest point, while swivel-platen machines cause corrugated box specimens to fail at their weakest point.

Spherical platens can be used in face-to-face testing to allow the platen to change angles and stay in contact with the non-uniform crushing of a container. You should make sure astk test five or more samples and average the data to improve the statistical reliability of the data.

Your compression test machine choice will depend on the maximum specimen size that you need to test.

The procedure may be used for measuring the ability of the container to resist external compressive loads applied to its faces, to diagonally opposite edges, or to corners Fig. Both platens need to be large enough to completely cover each end of the specimen.

ASTM D can be used to test packaging diagonally along opposite edges or top to bottom. When you are ready to perform this test, please refer to and follow the exact specifications in the official ASTM D document.

G Spherical Seat Compression Platens. Test Procedure Select a sample size and condition each specimen as indicated Carefully center the specimen on the bottom compression platen Slowly bring the top platen into contact with the specimen Apply the desired pre-load Make sure your system is set to specimen deformation Begin to apply load at the constant rate indicated in the specification Continue test until failure or specified load Repeat this procedure with each specimen.

Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.

Historical Version s – view previous versions of standard. We can create custom platens to your required specimen size. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. The lower platen should be rigid, such as the G23 Compression Platen this platen is required for edge or corner testing. Our engineers are familiar with ASTM D and can help guide you through the testing process, but we recommend you purchase and read the official ASTM standard to achieve the best results.

Our engineers would recommend pairing your compression tester with Xy Software to allow the user to collect all force and displacement data points during the test. Users can choose to test with fixed or spherical platens. The ISO standards may not meet the requirements for this test method.

ASTM D Test Method for Determining Compressive Resistance of Shipping Containers

We are confident that we have what you are looking for. However, a fixed-head compression machine is required to perform edge-to-edge and corner-to-corner orientations on test specimens see Note 2. ASTM D tests the compressive resistance of shipping containers including boxes and drums and components.

Standard load ratings up to kN 67, lbf ; higher ratings available upon request Platen diameters from 56 mm to mm 2. Give one of our engineers a call today and they can help guide you through the ASTM D test process with the best machine configuration for your requirements.

Fixed platens are rigidly mounted and can be used for corner testing, edge testing or face-to-face testing opposite sides of the box.
