1.Description Chase friction testing machine is used to evaluate the frictional characteristics of material in braking system in accordance with the SAE J661,GB 5763-2018 and GB/T 17469-2012. Chase machine is suitable for small bench test of M1, M2, N1, O1 and O2 vehicles brake linings. This machine is widely used for product formulation R&D, Quality control and Certification etc. 2.Principle A constant pressure is applied to the sample,which will be pressed against the inner surface of the friction drum which rotates at a certain speed, so a friction force will be generated along the tangent direction of the contact surface. The friction coefficient of the tested sample can be determined by measuring the pressure and friction force. During the test, the Chase friction tester controls the temperature change at any time according to the requirements. The drum outer ring is used to assist the heating tube heating and the back suction cooling, so that the temperature change at the sample is stable and the temperature measurement accuracy is higher. 3.Features (1)Loading by Pneumatic servo with high precision control. (2)Temperature of friction drum is adjustable to adapt to different test requirements and different climatic condition. (3)Rubbing speed can be set freely between 0 and 1000 RPM.

1. Introduction and test principle of compression strength measuring The compression testing machine is to measure compression strength of corrugated boxes in the situation of pressure and protect functions of packages for the objects filled in the packages. Test principle: (1) Corrugated boxes compression strength test, loading to the corrugated boxes using a compression testing machine at a certain constant rate untill corrugated boxes are broken or till certain load or displacement are reached. (2) Corrugated boxes stacking test, loading a certain force to the corrugated box using a compression testing machine untill corrugated box is broken or sustain a certain time period. When measuring deformation of corrugated box during compression test, an original load should be set as a datum point. The datum point can refer to the following chart: Average compression force(N)Original force(N) 101-200 10 201-1000 25 1001-2000 100 2001-10000 250 10001-20000 1000 200001-100000 2500 2.
