However, a fixed-head compression machine is required to perform edge-to-edge and corner-to-corner orientations on test specimens see Note 2. The best platen choice would be the TestResources G with an upper bearing.

We’re ready to help! 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. Planar Biaxial Testing Guide. We are confident that we have what you are looking for. Automotive Interior Mechanical Testing Guide. When you are ready to perform this test, please refer to and follow the exact specifications in the official ASTM D document.

Shipping containers may be tested with or without contents. 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. Our engineers recommend that you pair your compression test machine with an upper platen fit with a spherical bearing to ensure even distribution of load. Have a question about conducting the test for this standard?

The lower platen should be rigid, such as the G23 Compression Platen this platen is required for edge or corner testing. 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.

ASTM D 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. We can create custom platens to your required specimen size. During distribution and warehousing, items are placed under various compressive loads while being stacked and moved. ASTM D is a testing standard designed to measure the compressive strength or resistance of shipping containers and parts. Sales Support Calibration Calculators.

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

Standard load ratings up to kN 67, lbf ; higher ratings available upon request Platen diameters available from 56 mm to mm 2. Packaging components such as boxes, crates, and cases are designed to protect products while they are transported and stored.

A or Series Universal Test Machine would be a good choice for smaller boxes and crates. Your compression test machine choice will depend on the maximum specimen size that you need to test. 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 are subjected to during storage and distribution.

ASTM D Test Method for Determining Compressive Resistance of Shipping Containers

Speak with one of our fixture specialists to learn asrm about our compression platens. Testing packing components for compressive strength is needed to help guarantee the protection of the products inside them. ASTM D can be used to test packaging diagonally along opposite edges astn top to bottom. 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.

Fixed platens are rigidly mounted and can be used for corner testing, edge testing or face-to-face testing opposite sides of the box. Link to Active This link will r642 route to the current Active version of the standard. 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.

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.

G Spherical Seat Compression Platens. The values d624 in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. This test method covers testing of multiple containers or unit loads, in addition to individual shipping containers, components, zstm, or combination thereof.

The Series Universal Test Machine is aztm common choice for this standard, and specifically the Family are best for wide column spacing for large boxes, crates and pallets. Also, unit loads are generally tested only in the top-to-bottom orientation. How to Build a New Test.

Both platens need to be large enough to completely cover each end of the specimen. 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.

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. For constant load test refer to Test Method D Historical Version s – view previous versions of standard.

Force range of 5 kN to kN 1, lbf tolbf Adjustable test space The most popular choice for static tension and compression tests These dual column testers are available in both tabletop and floor standing models. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
