Unlike conventional compression methods, <strong>ISO 9895<\/strong> focuses on the intrinsic fiber strength of the material by minimizing buckling effects, making it one of the most reliable indicators of paper quality.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For laboratories, packaging manufacturers, paper mills, and R&amp;D departments, <strong>ISO 9895<\/strong> provides repeatable and comparable data that supports material development, process optimization, and quality assurance. A modern <strong>short span compression test machine<\/strong> allows engineers to obtain highly accurate compression strength values within seconds, improving production efficiency and confidence in material performance.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What Is ISO 9895?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>ISO 9895<\/strong> specifies the laboratory method for determining the <strong>short-span compression strength<\/strong> of paper and paperboard in both the machine direction (MD) and cross direction (CD).<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The method measures the maximum compressive force required to cause failure in a narrow specimen with an extremely short unsupported span. Because the unsupported length is only about <strong>0,70 mm<\/strong>, the test minimizes bending and buckling, allowing the measured force to reflect the true compressive strength of the fiber network.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The standard is primarily intended for:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Wellpappe<\/li>\n\n\n\n<li>Kraft linerboard<\/li>\n\n\n\n<li>Testliner<\/li>\n\n\n\n<li>Corrugating medium<\/li>\n\n\n\n<li>Folding boxboard<\/li>\n\n\n\n<li>Industrial paperboard<\/li>\n\n\n\n<li>Specialty packaging papers<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Most testing laboratories apply the method to materials with grammage between <strong>100 g\/m\u00b2 and 400 g\/m\u00b2<\/strong>, although other materials may also be evaluated depending on application requirements.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full is-resized\"><img fetchpriority=\"high\" decoding=\"async\" width=\"600\" height=\"600\" src=\"https:\/\/www.materialstests.com\/wp-content\/uploads\/2026\/07\/A-Strength-Test-for-Paper-Short-span-Compression-.webp\" alt=\"ISO 9895 | Festigkeitspr\u00fcfung f\u00fcr Papier \u2013 Kurzspannweiten-Druckversuch\" class=\"wp-image-3504\" style=\"width:310px;height:auto\" srcset=\"https:\/\/www.materialstests.com\/wp-content\/uploads\/2026\/07\/A-Strength-Test-for-Paper-Short-span-Compression-.webp 600w, https:\/\/www.materialstests.com\/wp-content\/uploads\/2026\/07\/A-Strength-Test-for-Paper-Short-span-Compression--300x300.webp 300w, https:\/\/www.materialstests.com\/wp-content\/uploads\/2026\/07\/A-Strength-Test-for-Paper-Short-span-Compression--150x150.webp 150w, https:\/\/www.materialstests.com\/wp-content\/uploads\/2026\/07\/A-Strength-Test-for-Paper-Short-span-Compression--12x12.webp 12w\" sizes=\"(max-width: 600px) 100vw, 600px\" \/><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\">Why Is ISO 9895 Important?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Compression strength directly influences how packaging materials perform throughout the supply chain.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Manufacturers use <strong>ISO 9895<\/strong> because it provides valuable information for:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Raw material evaluation<\/li>\n\n\n\n<li>Paper machine process control<\/li>\n\n\n\n<li>Product consistency verification<\/li>\n\n\n\n<li>Corrugated board quality prediction<\/li>\n\n\n\n<li>Packaging performance optimization<\/li>\n\n\n\n<li>Qualifikation der Lieferanten<\/li>\n\n\n\n<li>Research and development<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Compared with conventional compression tests, <strong>short-span compression strength testing<\/strong> offers better repeatability because the specimen fails by fiber compression rather than structural instability.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The test is especially valuable for predicting how linerboard and medium contribute to the final compression performance of corrugated boxes.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">How Does Short-Span Compression Testing Work?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The principle behind <strong>short-span compression testing<\/strong> is straightforward but highly precise.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A specimen measuring <strong>15 mm wide<\/strong> is securely clamped between two high-friction jaws. The unsupported span between the clamps is only <strong>0,70 mm<\/strong>.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">W\u00e4hrend des Tests:<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li>The sample is positioned between the clamps.<\/li>\n\n\n\n<li>A constant clamping force securely holds the specimen.<\/li>\n\n\n\n<li>The movable clamp advances toward the stationary clamp.<\/li>\n\n\n\n<li>Compression force increases until the specimen fails.<\/li>\n\n\n\n<li>The maximum force is recorded.<\/li>\n\n\n\n<li>Compression strength is calculated according to <strong>ISO 9895<\/strong>.<\/li>\n<\/ol>\n\n\n\n<p class=\"wp-block-paragraph\">Because the unsupported span is extremely short, failure occurs primarily through compression rather than bending, resulting in highly reproducible measurements.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">How To Ensure Accurate Results<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Ein Fachmann <strong>short span
