Durometer for body bushings??

[Snuffy]

Has anyone checked the durometer of the stock rubber body bushing?

Just wanted to check before I try to scrounge up a durometer and test a crusty one.

I'm lost. What is a durometer?

[twodogs]

I'm sure there's a technical definition of it, but I always took it to mean a measurement of how hard/resistant to deformity an object is.

Like polyurethane vs. rubber. Poly has a higher durometer.

Engineers?

Did I get points for that answer?

good enough for the girls I run around with.

Close twodogs...

Poly doesn't necessarily have a higher durometer. It just generally does for bushing applications.

No luck on a durometer at the University today... Kind of suprises me. I figured with all of the SAE programs on campus that they would have some form of testing. I'll get a penatrometer on Monday and convert the readings.

English please..

a penatrometer!!!

Durometer is one of several ways to indicate the hardness of a material, defined as the material's resistance to permanent indentation. It is named for instrument maker Albert F. Shore, who developed a measurement device called a durometer in the 1920s. The term durometer is often used to refer to the measurement, as well as the instrument itself. Durometer is typically used as a measure of hardness in polymers, elastomers and rubbers.


Durometer, like many other hardness tests, measures the depth of an indentation in the material created by a given force on a standardized presser foot. This depth is dependent on the hardness of the material, its viscoelastic properties, the shape of the presser foot, and the duration of the test. ASTM D2240 durometers allows for a measurement of the initial hardness, or the indentation hardness after a given period of time. The basic test requires applying the force in a consistent manner, without shock measuring the hardness (depth of the indentation). If a timed hardness is desired, force is applied for the required time and then read. The material under test should be a minimum of 6.4 mm (.25 inch) thick.

a penatrometer!!!

Picture please. I want to know what a penatrometer looks like. My mental image is, well, not good.
