Additional Information Jun 17, 2024 · The Edge Crush Test (ECT) is an essential test for corrugated cardboard packaging because it measures the ability of the material to stand up to compressive forces applied along its edges. 316243 required), the flat crush test (FCT) on single-sided and single-wall corrugated board to ISO 3035, EN 23035 and TAPPI T 825, and the corrugated medium test (CMT) to ISO 7263-1/-2 and TAPPI ECT – Edge Crush Test The Edge Crush Test is a traditional corrugated box test of compression strength. ABSTRACT: The use of paraffin wax to reinforce the loading edges of corrugated fiberboard edge-crush specimens requires that the specimens be reconditioned after waxing. To define the apparatus and test procedure used to determine the edgewise crush resistance of corrugated fibreboard. Therefore, it is of vital importance that the test is conducted using a Edge Crush Tester can be used to accurately measure the ECT Value. Federal and Military Specifications and Standards for corrugated board, the short column crush test is required. ISO 13821, Corrugated fibreboard — Determination of Mullen Tester Edge Crush Tester Corrugated Board Strength Equivalencies: Single Wall Corrugated Bursting Test Minimum Edge Crush Test Maximum Suggested Loading Limit Per Carton 125# 23 ECT 20 lbs. The method This document specifies a non-waxed edge method for the determination of the edgewise crush resistance of corrugated fibreboard.

ISO 13821, Corrugated fibreboard — Determination of Edge Crush vs Mullen Tests for Corrugated Cartons. A sample of a. identified under 10. Edge crush test value The amount of force needed to crush on edge combined board is a primary factor in predicting the compression strength of the completed box. In order to exclude unreliable displacement measurement in the standard edge crush test, virtual strain gauges were used Product Name: Edge Crush Test Cutter (ECT - Billerud Type) Product Code: PTA-N6800 Standards/Methods: TAPPI T 839, T 838, ISO 3037 Test Material: Board Testing methods & recommendations. As for tests like RCT and FCT, the specimen needs to be in a distinct shape, the machine so allows hold as per the specimen shape for all types of edge strength testing. The edgewise compressive strength (Edge Crush Test, or ECT) is a measure of the maximum force that a specimen of corrugated fibreboard can withstand without showing signs of crushing. A newer standard that has achieved widespread acceptance is the Edge Crush Test (ECT). Note 1: For each 10% reduction in mass of contents below maximum permitted, dimensions show in table may be RCT/FCT/Edge Crush Tester Digital is a consistent tool to measure the crush strength of cardboard boxes and packaging containers. per sq. 89 kilopascals kPa Force kilograms pounds 9.
