The short-span compressive strength test was developed by the Swedish Pulp and Paper Research Institute in the mid-1970s (1). The purpose of the test is to determine the edgewise .This test is one of the most commonly used to evaluate the edgewise compression strength of paper and board. From a strip of material with dimensions 15 Â 60 mm 2 , a short segment (0.7 mm).
SCT (short-span compression test) is one of the most commonly used testing methods for determining the compression strength of paper or cardboard. In this test, the sample is . 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. . (G MD, CD) will not enter into the analysis .17-36 Short Span Compression Tester. The 17-36 Short Span Compression Tester measures the compression strength of paper and board. The span (also known as the gap) is set to a distance of between 0.3-0.7mm. To perform an accurate compression test on such a short distance, it is essential that the clamps and instrument are extremely stable.
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.SCT-short span compression testing is an important test to predict the performance of container boards used to make corrugated boxes. Take your 15mm wide sample, place it between two air operated clamps and it’s then compressed. The maximum compressive strength is recorded and reported in Kilonewtons per meter.
The instrument employs the SCT-method (Short Span Compression Test), which has been well established for 40 years. The method is considered to be the best one for estimating and optimizing the compressive strength of liner or fluting. Methods such as the RCT-method (Ring Crush Test) can underestimate the strength of low grammage
L&W Compressive Strength Tester STFI leverages the Short-Span Compression Test (SCT) method to measure the compression strength of liner and fluting. Compressive strength determines the stacking ability of corrugated boxes. The aim is to produce strong boxes, and at the same time use a minimum of raw material. According to the Australian paperboard industry, RCT is a vital and relevant indication of package stacking performance compared to the Short-span compression test (SCT; Section 4.1.3) (Jackson .Possibility to compare MD and CD values.

The CLT is used in both the MD and CD directions of the liners. For CLT, one edge of a paper strip of length 152 mm and width 12.7 mm is clamped between two metal strips so that a free upper part of 6.3 mm protrudes above the clamp and load is applied to the free edge of the paper strip. . short-span compression test (SCT) and the ring crush .

The test is performed using a 15 mm wide paper or cardboard specimen and it is compressed until failure occurs.
The ring crush (RC) test and the short-span compression (STFI) test can be used to evaluate the compression strength of corrugated board components, and can be correlated with combined board strength.The ModularLine short span compressive test device consists of a punch mechanism in MD and CD, a transport unit and a fully-fledged short span compression tester, which is integrated within the lower part of the system. .The short span compressive test may measure a more fundamental paper property, but due to the level of variability in the material and the testing process, the ring crush test appears to serve as a better predictor
Leveraging the short-span compression test (SCT) method enables a shorter measuring distance and therefore no sample bending. This provides better results to.
The short span compression tester has been developed specially for the paper industry, and has exceptional ease of use and high measurement accuracy. Its open design allows samples to be easily placed in the test jaws. To allow measurement of thick as well as thin materials, the gap between the clamp jaws can be set, via the software,
