Abstract Plastic track is widely used in sports fields, such as stadiums, schools, and parks. However, it is important to maintain the quality of the plastic track to ensure the safety of athletes and prolong its lifespan. This article provides a comprehensive guide to plastic track testing, including the types of tests, testing equipment, testing procedures, and interpretation of test results. Introduction Plastic track is a popular choice for sports fields due to its durability, low maintenance, and excellent shock absorption properties. However, over time, plastic tracks may become worn, damaged, or contaminated, which can affect their performance and safety. Therefore, regular testing of plastic tracks is essential to identify any problems and ensure their quality. Types of Tests There are several types of tests that can be performed on plastic tracks, including: 1. Hardness Test: This test measures the hardness of the track surface, which can affect its shock absorption properties. A durometer is used to measure the hardness of the track surface, with a higher reading indicating a harder surface. 2. Tensile Strength Test: This test measures the strength of the track material, which can affect its resistance to wear and tear. A tensile testing machine is used to apply a force to a sample of the track material until it breaks, with a higher force indicating a stronger material. 3. Slip Resistance Test: This test measures the slip resistance of the track surface, which can affect its safety for athletes. A slip resistance tester is used to measure the coefficient of friction of the track surface, with a higher coefficient indicating a more slip-resistant surface. 4. UV Resistance Test: This test measures the resistance of the track material to UV radiation, which can cause fading and degradation of the material. A UV chamber is used to expose a sample of the track material to UV radiation for a specified period, with a lower level of degradation indicating better UV resistance. Testing Equipment To perform these tests, several pieces of equipment are required, including: 1. Durometer: A device used to measure the hardness of the track surface. 2. Tensile Testing Machine: A machine used to apply a force to a sample of the track material until it breaks. 3. Slip Resistance Tester: A device used to measure the coefficient of friction of the track surface. 4. UV Chamber: A chamber used to expose a sample of the track material to UV radiation. Testing Procedures To perform these tests, the following procedures should be followed: 1. Hardness Test: a. Select a representative area of the track surface to test. b. Place the durometer on the track surface and press down until the needle stops moving. c. Record the reading on the durometer. d. Repeat the test in several locations on the track surface. 2. Tensile Strength Test: a. Cut a sample of the track material to the required size. b. Mount the sample in the tensile testing machine. c. Apply a force to the sample until it breaks. d. Record the force required to break the sample. e. Repeat the test with several samples of the track material. 3. Slip Resistance Test: a. Select a representative area of the track surface to test. b. Place the slip resistance tester on the track surface and apply a specified force. c. Record the coefficient of friction of the track surface. d. Repeat the test in several locations on the track surface. 4. UV Resistance Test: a. Cut a sample of the track material to the required size. b. Place the sample in the UV chamber. c. Expose the sample to UV radiation for a specified period. d. Compare the appearance of the sample before and after exposure to UV radiation. Interpretation of Test Results After performing these tests, the results should be interpreted to determine the quality of the plastic track. The following guidelines can be used: 1. Hardness Test: A reading of 50-60 on the durometer is ideal for a plastic track surface. 2. Tensile Strength Test: A force of 5-10 kN is ideal for a plastic track material. 3. Slip Resistance Test: A coefficient of friction of 0.5 or higher is ideal for a plastic track surface. 4. UV Resistance Test: Minimal degradation of the track material indicates good UV resistance. Conclusion In conclusion, regular testing of plastic tracks is essential to ensure their quality and safety for athletes. By following the guidelines outlined in this article, sports field managers can identify any problems with their plastic tracks and take appropriate measures to maintain their performance and longevity.
