testing is conducted using a durometer in accordance with ISO 7619-1 and ASTM D2240 standards. The test measures the resistance of elastomeric materials to indentation under a standardized spring force. For Type 441 cable sheaths, the test involves pressing a truncated cone-shaped indenter into the sheath material surface and recording the depth of penetration after a specified dwell time. The Shore A scale ranges from 0 (maximum penetration, softest material) to 100 (no penetration, hardest material within the A scale range).<\/p>\n            <p class=\"cn-text\">\u90b5\u6c0fA\u786c\u5ea6\u6d4b\u8bd5\u4f7f\u7528\u786c\u5ea6\u8ba1\u6309\u7167ISO 7619-1\u548cASTM D2240\u6807\u51c6\u8fdb\u884c\u3002\u8be5\u6d4b\u8bd5\u6d4b\u91cf\u5f39\u6027\u6750\u6599\u5728\u6807\u51c6\u5316\u5f39\u7c27\u529b\u4e0b\u5bf9\u538b\u75d5\u7684\u62b5\u6297\u529b\u3002\u5bf9\u4e8e441\u578b\u7535\u7f06\u62a4\u5957\uff0c\u6d4b\u8bd5\u6d89\u53ca\u5c06\u622a\u9525\u5f62\u538b\u5934\u538b\u5165\u62a4\u5957\u6750\u6599\u8868\u9762\uff0c\u5e76\u5728\u89c4\u5b9a\u7684\u505c\u7559\u65f6\u95f4\u540e\u8bb0\u5f55\u7a7f\u900f\u6df1\u5ea6\u3002\u90b5\u6c0fA\u6807\u5ea6\u8303\u56f4\u4ece0\uff08\u6700\u5927\u7a7f\u900f\uff0c\u6700\u8f6f\u6750\u6599\uff09\u5230100\uff08\u65e0\u7a7f\u900f\uff0cA\u6807\u5ea6\u8303\u56f4\u5185\u6700\u786c\u6750\u6599\uff09\u3002<\/p>\n\n            <h3>Testing Parameters <span class=\"cn-text\">\u6d4b\u8bd5\u53c2\u6570<\/span><\/h3>\n            <div class=\"table-wrapper\">\n                <table>\n                    <thead>\n                        <tr>\n                            <th>Parameter <span class=\"cn-text\">\u53c2\u6570<\/span><\/th>\n                            <th>Specification <span class=\"cn-text\">\u89c4\u683c<\/span><\/th>\n                            <th>Standard Reference <span class=\"cn-text\">\u6807\u51c6\u53c2\u8003<\/span><\/th>\n                        <\/tr>\n                    <\/thead>\n                    <tbody>\n                        <tr>\n                            <td>Indenter Type <span class=\"cn-text\">\u538b\u5934\u7c7b\u578b<\/span><\/td>\n                            <td>Truncated cone (35\u00b0 included angle, 0.79 mm diameter) <span class=\"cn-text\">\u622a\u9525\uff0835\u00b0\u5939\u89d2\uff0c0.79\u6beb\u7c73\u76f4\u5f84\uff09<\/span><\/td>\n                            <td>ISO 7619-1<\/td>\n                        <\/tr>\n                        <tr>\n                            <td>Applied Force <span class=\"cn-text\">\u65bd\u52a0\u529b<\/span><\/td>\n                            <td>8.064 N (822 gf) spring force <span class=\"cn-text\">8.064\u725b\u987f\u5f39\u7c27\u529b<\/span><\/td>\n                            <td>ASTM D2240<\/td>\n                        <\/tr>\n                        <tr>\n                            <td>Dwell Time <span class=\"cn-text\">\u505c\u7559\u65f6\u95f4<\/span><\/td>\n                            <td>3 seconds (vulcanized rubber) \/ 15 seconds (thermoplastic) <span class=\"cn-text\">3\u79d2\uff08\u786b\u5316\u6a61\u80f6\uff09\/15\u79d2\uff08\u70ed\u5851\u6027\uff09<\/span><\/td>\n                            <td>ISO 7619-1<\/td>\n                        <\/tr>\n                        <tr>\n                            <td>Test Piece Thickness <span class=\"cn-text\">\u8bd5\u6837\u539a\u5ea6<\/span><\/td>\n                            <td>Minimum 6 mm <span class=\"cn-text\">\u6700\u5c0f6\u6beb\u7c73<\/span><\/td>\n                            <td>ISO 7619-1<\/td>\n                        <\/tr>\n                        <tr>\n                            <td>Measurement Points <span class=\"cn-text\">\u6d4b\u91cf\u70b9<\/span><\/td>\n                            <td>5 measurements, minimum 6 mm spacing <span class=\"cn-text\">5\u6b21\u6d4b\u91cf\uff0c\u6700\u5c0f6\u6beb\u7c73\u95f4\u8ddd<\/span><\/td>\n                            <td>AS\/NZS 3808<\/td>\n                        <\/tr>\n                        <tr>\n                            <td>Test Temperature <span class=\"cn-text\">\u6d4b\u8bd5\u6e29\u5ea6<\/span><\/td>\n                            <td>23\u00b0C \u00b1 2\u00b0C (standard conditions) <span class=\"cn-text\">23\u00b0C \u00b1 2\u00b0C\uff08\u6807\u51c6\u6761\u4ef6\uff09<\/span><\/td>\n                            <td>ISO 7619-1<\/td>\n                        <\/tr>\n                    <\/tbody>\n                <\/table>\n            <\/div>\n\n            <p>The hardness value reported is the arithmetic mean of the five measurements.
