Selection and Precautions of Ball Drop Rebound Tester

1. The difference between electrically releasing steel balls and manually releasing steel balls:

A: Manual release: The principle of manually releasing a steel ball is to use a magnet on the handle to attract the steel ball, and then separate the handle from the steel ball through artificial external force. This will inevitably cause the steel ball to deviate and rotate during the falling process, resulting in collision and deviation from the center when it comes into contact with the sample. Moreover, due to the different operating forces of each person or the same operator, it will also cause errors in the results and affect the success rate of the test.

B: Electric release: The principle of electric release of steel balls is to fix the steel ball perpendicular to the electromagnet and at the center of the organic glass tube. After the electromagnet loses its magnetism and falls freely after being powered off, it rebounds after coming into contact with the sample, greatly improving the efficiency of the test and the reliability of the data. At the same time, it also meets the requirement stipulated in the standard that the steel ball should not rotate and be in the center position when falling.

2. Advantages of both manual and automatic readings:

The accuracy of automatic measurement is relatively high, but if there are errors in the test results due to operational errors or uneven samples, manual readings can be used for comparison, effectively reducing the probability of errors and making the test data more rigorous.

3. Regarding the requirements for the value of the test results of the sample due to the rebound of the falling ball:

In the standard, there is an overview of the test results as follows:Test 3 samples per group, test 3 results for each sample, take the maximum value from the 3 results, and calculate the average of the 3 maximum values as the average rebound rate of the sampleHowever, some manufacturers in the market have failed to understand the requirements of the standard for test results, resulting in unreliable test data. At the same time, customers do not pay enough attention and importance to this issue. We hope to draw your attention to it.

The working principle of the sponge rebound coefficient tester is that after sponge, foam, rubber and other materials are formed, they should be stored for at least 72 hours before testing. Before testing, the sample should be conditioned in an environment with a temperature of 23 ± 2 ℃ and a relative humidity of 45% -50% for at least 16 hours, and then tested in the aforementioned environment.

The rectangular prism of the sample should have its upper and lower surfaces parallel to each other, and the sample is not allowed to have any skin.

The Chinese standard GB/T6670-2008 has replaced the GB/T6670-1997 Determination of Resilience of Flexible Cellular Plastics to the Determination of Resilience of Flexible foam Polymeric Materials by the Falling Ball Method. Two methods are used, namely, Method A and Method B.

Details of the determination content of the resilience of soft foam polymer materials by falling ball method:

Function of ISO8307 Sponge Ball Rebound Tester

1、 Test scope:

1.1 specifies two methods for determining the rebound performance of soft foam polymer materials.

1.2 It is applicable to the determination of falling ball resilience of soft foam polymer materials.

2、 The following terms and definitions apply to this standard.

2.1 Open cell soft foam material: soft foam material with closed cell volume less than 25%.

2.2 Closed cell flexible foam plastic: A flexible foam material with a closed cell volume greater than 25%.

Principle: A steel ball with a certain mass and diameter is dropped from a fixed height onto the surface of the sample. The height of the steel ball's bounce is measured, and the percentage of the ratio of the bounce height to the drop height is calculated.

Method A, Testing Instruments and Main Parameters:

Sponge ball rebound performance tester, including a transparent tube with an inner diameter of 30mm~60mm, a steel ball with a diameter of 16mm ± 0.5mm, a mass of 16.8g ± 1.5g, released by a magnet or other device. During the descent, there was no rotation and it remained in the center position. The falling height is 500mm ± 0.5mm. The distance between the top of the ball and the surface of the specimen should be 516mm. Therefore, the origin of zero rebound is the diameter distance of the steel ball above the surface of the specimen.

If the pipe is not vertical, it may cause measurement errors, and the steel ball will contact the inner wall of the pipe during the falling or rebounding process, rendering the measurement results invalid. Use a spirit level or similar device to calibrate the hard reference surface to ensure levelness, and place the transparent tube and frame vertically.
