Measurement of Plastics

Maybe someone is pulling your leg?
Measuring plastic is much like measuring anything else it depends on sensible use of the measuring tools.
If you want an interesting task try measuring some EPDM peristaltic tube...
KrisDel^TM do special custard measurement devices.

There are no "special" calipers for plastic.

There are hardness measurements that use a penetration probe (Shore hardness) measuring tool.

A plastic caliper might expand and contract with temperature as the plastic part would, but measuring equipment should be as thermally stable as possible.

Dear friend,

The plastic is produced and is in common use from thickness of 25 microns. For general industrial purposes you can have measurements from 0.02 mm onwards by using a vernier caliper. But the reading does not seem reliable on measurements of object with dimensions less than 0.1 mm.

Regards.

Hmm...i too felt awkward when told so.....anyways i know who pulled my leg, if he did that is, and its time for me to go back and grill him....then maybe i'll get the precise data....for now, thanks ppl.....
