What Is Coefficient Of Friction Cof Testing

Business Name: 
Idm Instruments Pty Ltd

Download the attached file for technical information on idm&39s model c0008. this horizontal cof employs the use of a stationary sled with a moving plane and coefficient of friction is measured directly from the resistance to tangential motion and the applied weight pressing the two pieces of sample together.summary of test method one specimen of the material under test is clamped to the horizontal plane surface and the other to the specimen sled. 

The plane is pulled under the stationary sled and the force or fictional resistance is measured and recorded. idm&39s cof tester model c0008 is currently being utilised by various industries worldwide. With custom options including pc control software, heated platens & touch screen lcd, idm provides only the best quality cof testers to the competitive market.<break>need an incline plane cof  you need idm&39s model c0045. 

Enquire now.friction  the resisting force that arises when a surface of one substance slides, or tends to slide, over an adjoining surface of itself or another substance.  Between surfaces of solids in contact there may be two kinds of friction<break>1 the resistance opposing the force required to start to move one surface over another known as static friction, <break>

 the resistance opposing the force to move one surface over another at a variable, fixed, or predetermined speed known as dynamic friction.slip  the lubricity of two surfaces sliding in contact with each other.  In effect, it is the exact opposite of friction, in that high coefficient of friction denotes low slip and low coefficient of friction denotes high slip.coeficient of friction  cof the ratio of the frictional force resisting movement of the surface being tested to the force applied normal to that surface the weight of the material above that surface.coefficient of static or starting friction the ratio of the force resisting initial motion of the surfaces, to the normal force coefficient of kinetic or sliding friction  the ratio of the force required to sustain the uniform relative movement of the surfaces, to the normal force. normal force the force acting perpendicular to the surfaces in contact.
