How do you measure the strength of containerboard paper? There are a number of standardized tests that are used to determine the strength and durability of c.Short Span Compression Testing (SCT) Short span compression testing measures the compression strength of paper and board materials over a very short compression span. The clamping arrangement is designed to prevent .
Our world class compression testing standards for paper manufacture. About . There are two ways of measuring the compression strength, the Ring Crush Test (RCT) and the Short-Span Compressive Test (SCT). Redefining Packaging for a Changing World . We are different because we see the opportunity for packaging to play a powerful role in the .L&W Autoline SCT . L&W Autoline SCT automates the measurement of compressive strength of liner and fluting for fast and precise results. It is based on the short-span compression test (SCT) method—first developed by the Swedish Pulp and Paper Institute (STFI) in collaboration with Lorentzen & Wettre.

The Short-span Compression Test (SCT) in the plane of the sheet is defined as the maximum compression breaking force, related to a sample width, that the sample resists a specified compression. The SCT is determined according to DIN 54518 with a .The Short Span Compression tester (SCT Test) is used for paper or board stripes with 15 mm width. The jaws clamps the stripe with definite force and then the clamps move from 0,7 mm towards the middle till a break is detected. On the touch screen display the curve is displayed and the value is shown.
Paperboard manufacturers need to better understand why the ring crush test (RCT) and the short-span compression test (SCT) respond differently in some cases, and similarly in other cases, to .
Test Description The sample to be tested is placed in the measurement area. It is created in the appropriate format by a pneumatic punch, moved to the lower part of the device automatically by a transport mechanism and placed in the fully-fledged short span compressive test device integrated there. The SCT test starts automatically. The Short span Compression Test (SCT) was originally developed to measure the compressive strength of paperboard and corrugated board intended to be used as packaging material. For SCT testing of paperboard, a specimen of the paper material is clamped between two clamps a distance 0.7 mm apart. Subsequently a compressive force is applied and .The SCT-21 determines the short span compression strength of papers for quality control (QC) and research and development (R&D) testing tasks. This property is a key characteristic for liner and fluting manufacturers as it influences strongly the stackability of a corrugated box. . The software enables complete program for compression test .

Short span compression. Short span compression test, SCT, tells you how much compression force your paper can take before the structure starts collapsing. A strip of paper is compressed between two clamps until the paper buckles. SCT .Short Span Compression (SCT) should Replace Ring Crush (RCT) 1. Short span compression is an easier, quicker and cheaper testing method, is available in automated systems, works for all basis weights – RCT does not track basis weight ! 2. The science behind SCT is sound and established: results correlate with basis weight, refining, fiber .SCT stands for Short-Span Compression Test (paper).
