What are the testing standards for the abrasion resistance tester of artificial turf

The artificial turf wear resistance testing machine is used to evaluate the wear resistance of artificial turf under repeated friction, and its testing standards are crucial to ensure the accuracy and comparability of the test results. Here is aboutArtificial turf abrasion resistance testing machineThe main testing standards are:

　　1、 Sample preparation standards

1. Sampling requirements: Representative samples should be randomly selected from the artificial turf roll or pre laid site to be tested. Avoid selecting edges, areas with obvious defects or damage to ensure that the sample can truly reflect the performance of the entire batch of products or site.

2. Sample size: Cut the sample into the appropriate size according to the fixture specifications and testing requirements of the artificial turf wear tester. Generally speaking, the sample area should be sufficient to cover the friction area of the testing machine and leave appropriate margin around for fixation.

3. Sample pretreatment: Before testing, the sample needs to be placed under standard environmental conditions (such as temperature of 23 ℃± 2 ℃, relative humidity of 50% ± 5%) for a certain period of time to reach a stable state and eliminate the influence of environmental factors on the test results.

　　2、 Testing environment standards

1. Temperature and humidity: The test should be conducted under relatively stable environmental temperature and humidity conditions. It is usually recommended to control the temperature between 20 ℃ -25 ℃ and the relative humidity between 40% -60%. Such environmental conditions help ensure the consistency and reliability of test results.

2. Testing site: The testing site should be flat and clean to avoid external vibrations and interference that may affect the operation of the testing machine. At the same time, the venue should have good ventilation conditions to prevent the accumulation of heat caused by friction from affecting the test results.

　　3、 Test parameter standards

1. Friction head or roller parameters: The material, shape, size, and surface roughness of the friction head or roller should comply with relevant standards and regulations. For example, friction heads are usually made of rubber materials with moderate hardness, and there are clear size requirements for the diameter and width of the rollers to ensure consistency and repeatability of the friction process.

2. Movement speed and frequency: Set appropriate friction head or roller movement speed and frequency according to different testing standards and application scenarios. Generally speaking, the exercise speed ranges from tens to hundreds of times per minute, and the frequency is adjusted according to actual needs. The setting of these parameters should be able to simulate the wear and tear of artificial turf in actual use.

3. Loading pressure: Loading pressure simulates the load that artificial turf can withstand in actual use. The magnitude of loading pressure should be set according to the expected usage scenarios and relevant standards of artificial turf, usually adjustable within a certain range to meet the testing requirements of different types and specifications of artificial turf.

　　4、 Evaluation criteria for test results

1. Appearance evaluation: After the test is completed, observe the wear of the sample surface with the naked eye, such as fiber breakage, detachment, fuzzing, and other phenomena. Evaluate the sample according to the predetermined grade standards based on the degree of wear.

2. Physical performance testing: In addition to appearance evaluation, some physical performance tests can also be conducted on the sample, such as measuring the weight and thickness changes of the sample before and after testing. By analyzing these data, the wear resistance of artificial turf can be more accurately evaluated.

Following the above testing standards can make the test results of the artificial turf abrasion tester more scientific and accurate, providing reliable basis for quality control and performance evaluation of artificial turf.
