By simulating real-world compression forces, this tester helps manufacturers assess the ability of paper products to withstand pressure during handling, stacking, and transportation.<\/p>\n\n\n\n<p>Cell Instruments&#8217; <strong data-start=\"951\" data-end=\"991\">SCT-01 Short Span Compression Tester<\/strong> offers high performance, ease of operation, and compliance with international standards, especially <strong data-start=\"1092\" data-end=\"1104\">ISO 9895<\/strong>, which governs the <strong data-start=\"1124\" data-end=\"1136\">SCT test<\/strong> method.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">SCT Test and ISO 9895<\/h2>\n\n\n\n<p>The <strong data-start=\"1200\" data-end=\"1212\">SCT test<\/strong> (Short-Span Compression Test) as defined in <a href=\"https:\/\/www.packqc.com\/nn\/standard\/iso-9895\/\"><strong data-start=\"1257\" data-end=\"1269\">ISO 9895<\/strong><\/a>, measures the compressive strength of paper and board over a very short span\u2014typically <strong data-start=\"1357\" data-end=\"1368\">0.70 mm<\/strong>.
