According to ASTM D642 Standard: Detailed Box Compression Strength Tester GT-N02A

ASTM D642 is an internationally recognised standard for assessing the compression resistance of paper packaging, applicable to corrugated boxes and cardboard materials. This test evaluates the compressive strength and load-bearing capacity of packaging materials by simulating the pressure experienced during stacking.

ASTM D642 Standard and Testing Method

ASTM D642 test method covers compression tests on shippingcontainers (for example,boxes and drums) or components,orboth. Shipping containers may be tested with or withoutcontents.The procedure may be used for measuring the ability of the container to resist external cormpressive loads applied toits faces, to diagonally opposite edges, or to corners.This test method covers testing of multiple containers or unit loads, in addition to individual shipping containers,components,materials, or combination thereof.

This test method is related to TAPPI T804, which issimilar for fixed platen machines but does not recognize swivelplaten machines.

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

Equipment Required for ASTM D642

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

Packaging Compression Tester Feature

Strength test

Strength test which belongs to a destructive test is mainly used to measure the deformation when the sample is loaded with maximum pressure or crushing strength.

Constant Value Test

There are two parameters which are to be set in the constant value test: load force value and deformation value. The user can set one or both of them according to the practical requirement. the measure is complete when any parameter reaches the set value.

Stacking Test

Stacking Test is used to check up that whether the sample can endure a constant pressure in a given time period. Set up two parameters: compressive strength and testing time (hour).

when the test starts, the system will check the current pressure at any moment to ensure the set value; the measure is complete when the test time is expired or the deformation value exceeds the set one within testing time.

The overall system is in good parallelism, stationarity and high return speed.
