Surface Hardness Test Report of Plastics and Carbon Fiber
Your esteemed company provided 2 specimens, as shown in the following picture,they are labeled as Specimen A and Specimen B.Parameters are shown in the following chart.
Label Test Part weight(g) Roughness(Ra/μm) Width/Diameter(cm) Height/Thickness(cm) Length(cm)
A Cylinder Surface 99 -- 78.03 -- 102.55
Ball Surface
202 -- 60.22 -- --

Picture of Sample:

2.Testing Instrument:
Shore durometer SI-200D was used to test Specimen A and B, setting parameters are shown as follows:
Instrument Name Model Scale Test Force Dwell Time Null Display Glass Surface Test
Shore Durometer SI-200D HD 5kgf -- 0HD 100HD
Conclusion:The Shore durometer SI-200D can be used to test the hardness of the specimen you provided

3.Test Data:
Use SI-200D to test the surface hardness of Specimen A and Specimen B respectively( handheld test), test results are shown in the following chart.
Instrument Specimen Scale Test 1 Test 2 Test 3 Test4 Test5 Average Value Standard Deviation
HD 80.5 80.5 81.5 81.0 81.5 81 0.50
B 94.5 95.5 95.0 95.5 96.0 95.3 0.57

4.Data Analysis:
Instrument  Scale Label Max Deviation Average Testing Value Standard Deviation
SI-200D HD A 1.0 81 0.50
B 1.5 95.3 0.57

1)Data Comparison:
Analyzing the data of Specimen A and B tested by SI-200D, it‘s known that  average value of A is 81.0HD , standard deviation is 0.5; average value of B is 95.3HD , standard deviation is 0.57.The test results of A and B are both in test range, and standard deviation is small, which means steady data.
Conclusion:SI-200D can test the hardness value of Specimen A and B accuratly and stably.
2)Advice on instrument purchasing:
It’s advised that your esteemed company perchase Model D hardness tester SI-200D, to test the hardness of  non - metallic rigid plastics
