According to ASTM D642 Standard: Detailed Box Compression Strength Tester GT-N02AASTM 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 MethodASTM 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 ProcedureSelect a sample size and condition each specimen as indicatedCarefully center the specimen on the bottom compression platenSlowly bring the top platen into contact with the specimenApply the desired pre-loadMake sure your system is set to specimen deformationBegin to apply load at the constant rate indicated in the specificationContinue test until failure or specified loadRepeat this procedure with each specimenEquipment Required for ASTM D642Your compression test machine choice will depend on the maximum specimen size that you need to test.Select the GESTER Box Compression Strength Tester GT-N02ABox Compression Strength Tester GT-N02B Type Compression Testing Machine with multi-function and high precision is designed to test the compressive strength of standard size corrugated box, or packages and containers made of other material with a compressive strength smaller than 100kN. Can conduct tensile, compression, bending, shearing, tearing and peeling test; use PC and interface board for data collection, preservation, processing and printing test result; can calculate max force, yield strength, average peeling force, max deformation, yield point, elastic modulus and other parameters.Measuring range: 0-10KN, 20KN, 30KN, 50KN, 70KN, 100KN (Optional)Test Standards: ISO2872, ISO2874, ISO 12048, ASTM D642, TAPPI T804Packaging Compression Tester FeatureStrength testStrength 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 TestThere 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 TestStacking 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.

How to Improve the Accuracy of a Martindale Tester1: Use the GESTER Martindale TesterNew and upgraded design martindale abrasion and pilling tester is driven by dual servo system. Standard Lissajous figure motion trajectory is generated by digital algorithm.Instead of the structure supported by steel balls, avoids the risk of uneven cover plate caused by ball wear. The cover plate can be folded and turned up to facilitate sample loading and test results.The added lubricating oil injection hole is convenient for customers to maintain and ensure that the machine can run stably for a long time.2: Steps to Improve Martindale Tester AccuracyFollowing these steps will assist you in conducting tests efficiently and enhancing the accuracy of your Martindale tester.Martindale Abrasion Test Sample PreparationProper sample preparation is crucial for obtaining accurate and reproducible results. A specified number of circular test specimens must be cut.Specimens must be flat, undamaged, and cut to the specified dimensions.Select appropriate sandpaper or standard abrasives, ensuring their surfaces are smooth and free from granular protrusions.Prepare auxiliary materials such as standard felt and standard foam pads.The specimen should be conditioned in an environment of 21 ± 1°C and 65 ± 2% humidity for 4 hours prior to testing.Secure Clamping and Correct InstallationPosition the specimen-holding fixture on the grinding machine. Set parameters such as the number of cycles according to the relevant test standards.Initiating Testing:Set the counting parameters and select the test mode on the touchscreen. Choose the desired workstations and start the test. The instrument will then perform the abrasion test according to the preset parameters and motion trajectory.The GESTER martindale abrasion and pilling tester features six test modes: 60×60 Abrasion/Pilling, 24×24 Pilling, 60-X, 60-Y, 24-X, 24-Y. The system enables one-touch switching between modes without additional hardware conversion.This martindale abrasion machine measures the abrasion resistance and pilling properties of various textile structures. Specimens undergo continuous directional friction against a known abrasive material under low pressure, with wear or pilling levels compared against standard parameters.Maintenance and CareAfter Testing:Upon test completion, switch off the power supply to halt the Martindale abrasion tester. Clear the test area and return all specimens, abrasive paper, and other items to their designated locations. This helps maintain the cleanliness of the instrument and its surroundings.Routine Maintenance:Regularly clean and inspect the instrument to ensure it maintains optimal performance and accuracy. Check the power cord and connectors for any damage and ensure they are secure. Periodically examine components such as the abrasion platform, guide plates, and friction heads for wear. Replace or repair any worn parts promptly if necessary.
