strength are among the most critical mechanical properties when selecting tunnelling cables and tunnel boring machine (TBM) cables. These cables face extremely harsh operating conditions including continuous friction with rocks and debris, repeated dynamic movement during reeling and unreeling operations, and high mechanical stress from heavy equipment. According to international standards such as ISO 4649 and DIN 53516 for abrasion resistance, and ISO 34-1 and ASTM D624 for tear strength, accurate assessment of these properties is essential to ensure reliable performance and operational safety. The selection of appropriate sheath materials\u2014TPU (Thermoplastic Polyurethane), PUR (Polyurethane Rubber), CPE (Chlorinated Polyethylene), or EPR (Ethylene Propylene Rubber)\u2014directly impacts cable longevity, safety, and operational efficiency in demanding underground environments.\n                <\/div>\n                \n                <div class=\"text-cn\">\n                    <strong>\u7e41\u9ad4\u4e2d\u6587\uff1a<\/strong> \u8010\u78e8\u6027\u548c\u6495\u88c2\u5f37\u5ea6\u662f\u9078\u64c7\u96a7\u9053\u96fb\u7e9c\u548c\u96a7\u9053\u6398\u9032\u6a5f\uff08TBM\uff09\u96fb\u7e9c\u6642\u6700\u95dc\u9375\u7684\u6a5f\u68b0\u6027\u80fd\u4e4b\u4e00\u3002\u9019\u4e9b\u96fb\u7e9c\u9762\u81e8\u6975\u5176\u60e1\u52a3\u7684\u64cd\u4f5c\u689d\u4ef6\uff0c\u5305\u62ec\u8207\u5ca9\u77f3\u548c\u788e\u5c51\u7684\u6301\u7e8c\u6469\u64e6\u3001\u5377\u7e5e\u548c\u5c55\u958b\u64cd\u4f5c\u671f\u9593\u7684\u53cd\u8907\u52d5\u614b\u904b\u52d5\uff0c\u4ee5\u53ca\u4f86\u81ea\u91cd\u578b\u8a2d\u5099\u7684\u9ad8\u6a5f\u68b0\u61c9\u529b\u3002\u6839\u64daISO 4649\u548cDIN 53516\u8010\u78e8\u6027\u6a19\u6e96\uff0c\u4ee5\u53caISO 34-1\u548cASTM D624\u6495\u88c2\u5f37\u5ea6\u6a19\u6e96\uff0c\u6e96\u78ba\u8a55\u4f30\u9019\u4e9b\u6027\u80fd\u5c0d\u65bc\u78ba\u4fdd\u53ef\u9760\u6027\u80fd\u548c\u64cd\u4f5c\u5b89\u5168\u81f3\u95dc\u91cd\u8981\u3002\u9078\u64c7\u9069\u7576\u7684\u8b77\u5957\u6750\u6599\u2014\u2014TPU\uff08\u71b1\u5851\u6027\u805a\u6c28\u916f\uff09\u3001PUR\uff08\u805a\u6c28\u916f\u6a61\u81a0\uff09\u3001CPE\uff08\u6c2f\u5316\u805a\u4e59\u70ef\uff09\u6216EPR\uff08\u4e59\u4e19\u6a61\u81a0\uff09\u2014\u2014\u76f4\u63a5\u5f71\u97ff\u96fb\u7e9c\u5728\u8981\u6c42\u82db\u523b\u7684\u5730\u4e0b\u74b0\u5883\u4e2d\u7684\u4f7f\u7528\u58fd\u547d\u3001\u5b89\u5168\u6027\u548c\u904b\u71df\u6548\u7387\u3002\n                <\/div>\n            <\/section>\n\n            <section class=\"content-section\">\n                <div class=\"section-header\">\n                    <h2 class=\"section-title\">\n                        \u0627\u062e\u062a\u0628\u0627\u0631 \u0645\u0642\u0627\u0648\u0645\u0629 \u0627\u0644\u062a\u0622\u0643\u0644: \u0627\u0644\u0645\u0639\u0627\u064a\u064a\u0631 \u0627\u0644\u062f\u0648\u0644\u064a\u0629 \u0648\u0637\u0631\u0642 \u0627\u0644\u0627\u062e\u062a\u0628\u0627\u0631\n                        <span class=\"section-title-sub en\">Abrasion Resistance Testing: International Standards &#038; Test Methods<\/span>\n                        <span class=\"section-title-sub cn\">\u8010\u78e8\u6027\u6e2c\u8a66\uff1a\u570b\u969b\u6a19\u6e96\u8207\u6e2c\u8a66\u65b9\u6cd5<\/span>\n                    <\/h2>\n                <\/div>\n\n                <p>\u064a\u064f\u0642\u064a\u0651\u0645 \u0627\u062e\u062a\u0628\u0627\u0631 \u0645\u0642\u0627\u0648\u0645\u0629 \u0627\u0644\u062a\u0622\u0643\u0644 \u0642\u062f\u0631\u0629 \u063a\u0644\u0627\u0641 \u0627\u0644\u0643\u0627\u0628\u0644 \u0639\u0644\u0649 \u062a\u062d\u0645\u0644 \u0627\u0644\u0627\u062d\u062a\u0643\u0627\u0643 \u0627\u0644\u0633\u0637\u062d\u064a \u0627\u0644\u0645\u0633\u062a\u0645\u0631 \u062f\u0648\u0646 \u062a\u062f\u0647\u0648\u0631 \u0643\u0628\u064a\u0631. \u064a\u064f\u0639\u062a\u0628\u0631 \u0645\u0639\u064a\u0627\u0631 DIN 53516 (\u0627\u0644\u0645\u0639\u0631\u0648\u0641 \u0623\u064a\u0636\u0627\u064b \u0628\u0640 ISO 4649) \u0645\u0646 \u0623\u0643\u062b\u0631 \u0627\u0644\u0645\u0639\u0627\u064a\u064a\u0631 \u0627\u0633\u062a\u062e\u062f\u0627\u0645\u0627\u064b \u0639\u0627\u0644\u0645\u064a\u0627\u064b \u0644\u0647\u0630\u0627 \u0627\u0644\u063a\u0631\u0636. \u064a\u062a\u0645 \u0641\u064a \u0647\u0630\u0627 \u0627\u0644\u0627\u062e\u062a\u0628\u0627\u0631 \u0642\u064a\u0627\u0633 \u0641\u0642\u062f\u0627\u0646 \u0627\u0644\u062d\u062c\u0645 \u0628\u0627\u0644\u0645\u064a\u0644\u064a\u0645\u062a\u0631 \u0627\u0644\u0645\u0643\u0639\u0628 (mm\u00b3) \u0628\u0639\u062f \u062a\u0639\u0631\u064a\u0636 \u0639\u064a\u0646\u0629 \u0623\u0633\u0637\u0648\u0627\u0646\u064a\u0629 \u0644\u0644\u0627\u062d\u062a\u0643\u0627\u0643 \u0645\u0639 \u0648\u0631\u0642\u0629 \u0643\u0627\u0634\u0637\u0629 \u0639\u0644\u0649 \u0623\u0633\u0637\u0648\u0627\u0646\u0629 \u062f\u0648\u0627\u0631\u0629 \u0628\u0633\u0631\u0639\u0629 40 \u062f\u0648\u0631\u0629 \u0641\u064a \u0627\u0644\u062f\u0642\u064a\u0642\u0629 \u062a\u062d\u062a \u062d\u0645\u0644 \u0645\u062d\u062f\u062f.<\/p>\n\n                <div class=\"text-en\">\n                    <strong>English:<\/strong> Abrasion resistance testing evaluates a cable sheath&#8217;s ability to withstand continuous surface friction without significant degradation. The DIN 53516 standard (also known as ISO 4649) is among the most globally recognized standards for this purpose. This test measures volume loss in cubic millimeters (mm\u00b3) after exposing a cylindrical specimen to friction against an abrasive sheet mounted on a rotating drum at 40 rpm under a specified load. The test methods include Method A (non-rotating test piece) and Method B (rotating test piece), with results reported as either relative volume loss or an abrasion resistance index. Lower volume loss values indicate superior abrasion resistance\u2014a critical factor for tunnelling cables exposed to continuous contact with rough surfaces, rocks, and debris.

ISO 34-1:2022 and ASTM D624 are the primary international standards for this test, measuring the force required to propagate a tear in a pre-cut specimen. ISO 34-1 specifies three test piece geometries: trouser (Method A), angle (Method B), and crescent (Method C). The trouser test is preferred because it is not sensitive to cut length and results are more easily related to fundamental tear properties. The test applies force using a tensile testing machine at 500 mm\/min \u00b1 50 mm\/min until the specimen breaks. Tear strength is calculated by dividing the maximum or median force by the specimen thickness, expressed in kN\/m or N\/mm.\n                <\/div>\n\n                <div class=\"text-cn\">\n

<strong>English:<\/strong> The following table presents a comprehensive comparison of different sheath materials used in tunnelling and TBM cables, focusing on mechanical, chemical, and thermal properties relevant to tunnel boring applications. TPU (Thermoplastic Polyurethane) demonstrates superior performance across most parameters, particularly in abrasion resistance, tear strength, and oil resistance, making it the preferred choice for demanding TBM applications. The tensile strength of TPU is 2-3 times that of natural rubber and synthetic rubber compounds, with polyester-based polyurethane achieving tensile strengths approaching 60 MPa and elongations exceeding 400%. Mining cables are specially engineered to withstand harsh underground environments and must meet strict international standards including MSHA, IEC, and DIN VDE requirements for flame retardancy, abrasion resistance, and mechanical durability.\n                <\/div>\n\n                <div class=\"text-cn\">\n                    <strong>\u7e41\u9ad4\u4e2d\u6587\uff1a<\/strong>
