It measures the maximum force required for a plunger to penetrate a clamped specimen, providing\n    a peak puncture resistance value in kilonewtons (kN). The instrument accommodates a wide range of materials,\n    including geotextiles, geomembranes, geogrids, drainage boards, and geosynthetic clay liners. During testing, its 5\n    kN load frame drives the plunger into the specimen held between two circular clamping rings. A load cell\n    continuously measures the applied force in relation to displacement, generating a force-displacement curve. The\n    highest point on this curve represents the material's puncture resistance and helps determine its ability to\n    withstand localized pressure from angular aggregate and other irregular surfaces beneath an overlying load.\u003c\/p\u003e\n\u003cp\u003eA key aspect of the QualiGTX™ CBR R is its automated specimen clamping mechanism, which eliminates the need for\n    manual securing before each test. The system applies consistent clamping pressure whenever a new test begins,\n    reducing operator-related differences that can affect measurement repeatability. An industrial touchscreen\n    microcomputer manages the testing process, displays the force-displacement curve in real time, and generates a\n    structured report upon completion. Test data can also be exported for further evaluation or transferred to a\n    laboratory information management system, eliminating the need for manual data entry.\u003c\/p\u003e\n\u003cp\u003eThe tester supports the quality control and material evaluation requirements of geosynthetic manufacturers,\n    certification organizations, and construction testing laboratories. Its adaptable configuration allows different\n    specimen types to be tested using the same load frame, with the appropriate plunger and clamping accessories.\n    Compatible materials include woven separation geotextiles, smooth HDPE liners, composite geomembranes, plastic\n    geogrids, drainage boards, and bentonite mats. This versatility provides laboratories handling multiple geosynthetic\n    product categories with a consolidated testing solution.\u003c\/p\u003e\n\u003ch2\u003eRapid CBR Puncture Tester – QualiGTX™ CBR R Applications\u003c\/h2\u003e\n\u003cp\u003eResistance to static puncture is an important selection criterion for geosynthetic materials installed beneath heavy\n    loads or against surfaces containing sharp, irregular particles.

As soil, aggregate, or other overlying materials exert pressure, the geosynthetic is forced against\n    stones and debris beneath it. The resulting contact stress gradually increases over an extended period. Static\n    puncture testing simulates this loading condition by moving a plunger into a securely clamped specimen at a\n    controlled, relatively low speed. As the plunger advances, the material stretches around its tip and the applied\n    force increases. Once the specimen reaches its maximum load-bearing capacity, it can no longer distribute the\n    developing stress effectively. Penetration then begins, producing a sharp reduction in the measured force. The\n    highest force recorded immediately before this failure represents the specimen's puncture resistance.\u003c\/p\u003e\n\u003cp\u003eThe arrangement of the clamping rings plays an important role in determining the resulting measurement. When a\n    specimen is secured between circular rings, the unsupported central section is exposed to the advancing plunger.\n    This produces biaxial tensile deformation as the material stretches in multiple directions, unlike the predominantly\n    uniaxial deformation associated with conventional strip tensile testing. The resulting stress condition provides a\n    closer representation of buried geosynthetic behavior, where the material is constrained by surrounding soil rather\n    than having an unsupported free edge.\u003c\/p\u003e\n\u003cp\u003ePlunger diameter and the clear opening of the clamping assembly also influence how the specimen fails. A larger\n    plunger distributes the applied load across a wider contact area, allowing extensible nonwoven materials to deform\n    and draw down before rupture. A smaller plunger concentrates the applied force over a more localized region,\n    increasing the likelihood of localized material failure. Consequently, puncture resistance results are directly\n    comparable only when the testing geometry is consistent.\u003c\/p\u003e\n\u003cp\u003eThe QualiGTX™ CBR R controls this loading process through a load cell with ±1% indication accuracy and 0.02% minimum\n    resolution. These measurement capabilities capture changes throughout the force-displacement response, including the\n    transition region where extensible materials begin to yield. Its adjustable test speed of 10 to 60 mm\/min\n    accommodates the loading rates specified in different geosynthetic puncture protocols. Maintaining the required\n    speed is important because polymer stiffness can increase as the rate of applied loading rises. The 110 mm vertical\n    stroke provides the travel needed for highly extensible materials, particularly needle-punched nonwovens, to undergo\n    substantial deformation before tearing. This allows the test to continue until actual specimen rupture rather than\n    ending prematurely because the plunger has reached its travel limit.\u003c\/p\u003e\n\u003ch2\u003eRapid CBR Puncture Tester - QualiGTX™ CBR R Technical Specifications\u003c\/h2\u003e\n\u003ctable class=\"table table-style-align-center\" align=\"center\" border=\"1\" cellspacing=\"0\" cellpadding=\"0\"\u003e\n    \u003cthead\u003e\n        \u003ctr\u003e\n            \u003cth\u003eParameter\u003c\/th\u003e\n            \u003cth\u003eSpecification\u003c\/th\u003e\n        \u003c\/tr\u003e\n    \u003c\/thead\u003e\n    \u003ctbody\u003e\n        \u003ctr\u003e\n            \u003ctd\u003eTest Principle\u003c\/td\u003e\n            \u003ctd\u003eStatic puncture, plunger driven through a clamped circular specimen\u003c\/td\u003e\n        \u003c\/tr\u003e\n        \u003ctr\u003e\n            \u003ctd\u003eMeasured Property\u003c\/td\u003e\n            \u003ctd\u003ePeak puncture resistance (kN), force versus displacement curve\u003c\/td\u003e\n        \u003c\/tr\u003e\n        \u003ctr\u003e\n            \u003ctd\u003eMaximum Test Force\u003c\/td\u003e\n            \u003ctd\u003e5 kN\u003c\/td\u003e\n        \u003c\/tr\u003e\n        \u003ctr\u003e\n            \u003ctd\u003eIndication Accuracy\u003c\/td\u003e\n            \u003ctd\u003e±1%\u003c\/td\u003e\n        \u003c\/tr\u003e\n        \u003ctr\u003e\n            \u003ctd\u003eMinimum Resolution\u003c\/td\u003e\n            \u003ctd\u003e0.02%\u003c\/td\u003e\n        \u003c\/tr\u003e\n        \u003ctr\u003e\n            \u003ctd\u003eTest Speed Range\u003c\/td\u003e\n            \u003ctd\u003e10 to 60 mm\/min\u003c\/td\u003e\n        \u003c\/tr\u003e\n        \u003ctr\u003e\n            \u003ctd\u003eVertical Stroke\u003c\/td\u003e\n            \u003ctd\u003e0 to 110 mm\u003c\/td\u003e\n        \u003c\/tr\u003e\n        \u003ctr\u003e\n            \u003ctd\u003eSpecimen Clamping\u003c\/td\u003e\n            \u003ctd\u003eAutomatic\u003c\/td\u003e\n        \u003c\/tr\u003e\n        \u003ctr\u003e\n            \u003ctd\u003eControl System\u003c\/td\u003e\n            \u003ctd\u003eIndustrial touchscreen microcomputer\u003c\/td\u003e\n        \u003c\/tr\u003e\n        \u003ctr\u003e\n            \u003ctd\u003eData Output\u003c\/td\u003e\n            \u003ctd\u003eAutomatic report generation, data export for analysis\u003c\/td\u003e\n        \u003c\/tr\u003e\n        \u003ctr\u003e\n            \u003ctd\u003eCompatible Materials\u003c\/td\u003e\n            \u003ctd\u003eGeotextile, geomembrane, composite geomembrane, plastic geogrid, drainage and waterproofing board,\n                geosynthetic clay liner\u003c\/td\u003e\n        \u003c\/tr\u003e\n        \u003ctr\u003e\n            \u003ctd\u003eVoltage\u003c\/td\u003e\n            \u003ctd\u003eAC 220 V, 50 Hz (110V is also available)\u003c\/td\u003e\n        \u003c\/tr\u003e\n        \u003ctr\u003e\n            \u003ctd\u003eDimensions (W × D × H)\u003c\/td\u003e\n            \u003ctd\u003e700 × 620 × 1360 mm\u003c\/td\u003e\n        \u003c\/tr\u003e\n        \u003ctr\u003e\n            \u003ctd\u003eWeight\u003c\/td\u003e\n            \u003ctd\u003e150 kg\u003c\/td\u003e\n        \u003c\/tr\u003e\n    \u003c\/tbody\u003e\n\u003c\/table\u003e","brand":"Qualitest USA LC","offers":[{"title":"Default Title","offer_id":53605858345271,"sku":null,"price":100.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0786\/1859\/1543\/files\/rapid-cbr-puncture-tester1293251.webp?v=1794486169","url":"https:\/\/qualitest.us\/pt\/products\/rapid-cbr-puncture-tester","provider":"Qualitest USA LC","version":"1.0","type":"link"}
