Tinius Olsen - ASTM D2519-02 Electrical Insulating Varnish


830-001 ASTM D2519-02 Electrical Insulating Varnish

The ASTM standards (sometimes) give accurate and very precise instructions on how a specific test should be performed. This is an example of one of these tests, the parts and method are explicitly layed out within the standard document.

This attachment uses a 3 point bend applied to a coil to test the strength of Electrical Insulating Varnish.

The coil, made from various metals, are wrapped tightly around an anvil. The anvil is then removed and the coil placed in the varnish solution.
The coated coil is then placed in this 3-point bend and then tested. This is then used to show the properties of the varnish when applied to the metal.

As this test uses the appropriate materials in an accurate situation it should produce good results.
