As a key material in interior soft decoration and commercial flooring applications, carpets are widely used in residential spaces, hotel lobbies, office buildings, exhibition halls, shopping malls, and other public environments. During long-term service, carpets are continuously subjected to static loads caused by stationary furniture, prolonged standing of people, heavy object placement, and other pressure conditions.The Carpet Static Load Tester adopts a constant static pressure loading method to accurately simulate the actual working conditions of carpets under long-term static compression. Through controlled loading, timed pressure holding, and precise displacement measurement, the tester quantitatively evaluates key performance indicators such as carpet thickness loss rate, residual deformation, and recovery resilience.Featuring stable operation, accurate measurement, and excellent adaptability to real application conditions, this equipment is an essential testing instrument for carpet manufacturers, soft furnishing and building material suppliers, third-party quality inspection organizations, and university material research laboratories.

Components of Carpet Static Load Tester

1. The tester is equipped with an integrated thickened steel frame, anti-slip fixed base, and horizontal leveling knobs. The robust structure effectively minimizes slight vibrations during the loading process, ensuring stable operation. It guarantees that the compression plate moves vertically downward with uniform force distribution, providing a reliable foundation for standardized testing.

2. The system consists of standard national calibration weights, a vertical guide transmission mechanism, and a flat load-bearing compression plate, which provide accurate and constant static pressure loading. The compression plate maintains uniform force distribution without tilting, ensuring consistent pressure across the entire specimen area and fully complying with standard test conditions.

Equipped with a high-precision displacement sensor, thickness measurement probe, and data acquisition module, the tester can accurately capture thickness variations of the specimen at different testing stages. It achieves millimeter-level measurement accuracy, ensuring precise and reliable deformation and recovery rate data.

3. The tester features a touchscreen control panel, programmable timer module, automatic start/stop system, and audible & visual alarm device. It supports customized parameter settings and enables fully automated operation throughout the entire testing process, providing convenient operation and suitability for various testing applications.

The flat anti-slip test platform, specimen positioning limit plates, and flexible protective cushioning layer can securely fix carpet specimens of different sizes and materials, preventing specimen displacement during testing, reducing measurement errors, and ensuring high testing accuracy.

Testing Principles of Carpet Static Load Tester

1. Constant Static Pressure Uniform Loading Principle

The tester utilizes a standard calibration weight module and precision transmission structure to apply a constant vertical downward load to the compression plate. The pressure is evenly distributed across the surface of the carpet specimen, eliminating localized stress concentration.

Unlike manual loading methods, which suffer from inconsistent force application and pressure fluctuations, the tester achieves stable load output through mechanical weighting, accurately simulating real-life static loading conditions such as furniture placement, heavy object storage, and prolonged standing.

The constant pressure continuously compresses the surface pile fibers and internal cushioning layers of the carpet, precisely reproducing the physical changes caused by long-term loading, including fiber compaction and pore structure reduction. This ensures consistent test conditions for each test cycle and provides highly comparable and repeatable test results.

2. Timed Pressure Holding and Time Accumulation Principle

Permanent deformation of carpets is not caused by instantaneous loading but results from the cumulative effect of long-term pressure exposure. The tester is equipped with an intelligent timing control system, allowing users to set different pressure holding durations such as 5 minutes, 30 minutes, and 2 hours according to national standards and testing requirements.

Through continuous static pressure loading, the system accelerates the accumulation of fatigue damage, inducing failure phenomena such as carpet fiber compaction and cushioning layer compression relaxation.

Short-duration pressure holding is suitable for routine production quality inspection, while long-duration pressure holding is applicable for extreme performance verification of new products. This method effectively simulates aging and wear caused by long-term carpet usage while significantly reducing testing time, enabling rapid prediction of carpet surface collapse and durability performance after extended service.

3. Thickness Difference Deformation Quantification Principle

Thickness reduction and residual deformation are key indicators for evaluating the compression resistance of carpets. The tester is equipped with a high-precision displacement measurement module, which collects three sets of critical data:

Initial specimen thickness

Compressed thickness under pressure holding

Residual thickness after unloading and recovery

The built-in calculation system automatically determines the compression deformation rate and recovery resilience rate based on these measurements.

High-quality carpets feature excellent fiber elasticity and stable cushioning structures, allowing rapid recovery after unloading with minimal residual deformation. In contrast, carpets made with inferior fibers or weak cushioning structures are prone to irreversible permanent collapse after compression, resulting in significantly reduced recovery performance.

This principle converts subjective evaluations such as softness, comfort, and durability into accurate digital parameters, enabling objective classification and quality assessment of carpet performance.

4. Fiber Structure Fatigue Failure Evaluation Principle

Carpets are porous flexible fiber composite structures consisting of surface pile fibers, intermediate foam cushioning layers, and bottom anti-slip backing layers. Each structural layer has different compression resistance and recovery characteristics.

Under continuous static pressure, surface pile fibers gradually flatten and become compacted, reducing the gaps between fibers. Meanwhile, the intermediate cushioning layer undergoes both elastic and plastic deformation. With prolonged loading, plastic deformation continues to accumulate, eventually resulting in permanent compression and collapse.

Through standardized static compression testing, the tester can accurately distinguish between elastic deformation and permanent plastic deformation, identify weak points within the carpet structure, and evaluate the influence of fiber materials, weaving processes, and cushioning layer formulations. The obtained data provides reliable support for product design optimization and manufacturing improvement.

5. Intelligent Sequential Closed-Loop Control Principle

The tester is equipped with a programmable intelligent control system, enabling fully automated operation throughout the entire testing process, including loading, pressure holding, unloading, recovery resting, and data acquisition.

The system allows flexible setting of test parameters and automatically performs the complete test sequence. After completion, the tester automatically stops and stores all test data. It is also equipped with safety functions including overload protection, travel limit protection, and abnormal alarm functions.

The entire testing process requires no manual intervention. Test results are automatically recorded and securely stored, ensuring data traceability and integrity. The system fully meets the requirements of quality management systems and third-party inspection standards in the building materials industry, making it suitable for standardized and regulated quality control applications.
