Abstract
A testing assembly measures the friction of a coating of a test piece having a defined length. The testing assembly comprises a base and a tower fixedly secured to the base. A receiving channel extends through the tower. The receiving channel has a predetermined diameter for receiving the test piece therein. The testing assembly also includes a port extending along a portion of the receiving channel. The port provides access to the test piece at various points along its defined length such that temperature readings of the test piece can be taken as torque and tension are measured.
Claims21
A testing assembly for measuring friction of a coating of a test piece having a defined length, said testing assembly comprising:
- a base;
- a tower fixedly secured to said base;
- a receiving channel extending through said tower, said receiving channel having a predetermined diameter for receiving the test piece therein;
- and
- a port extending along a portion of said receiving channel for accessing the test piece at various points along the defined length such that temperature readings of the test piece can be taken when torque and tension are measured.
A clamping fixture assembly insertable into a tower having a port and a key to have a test piece and a fastener secured to said clamping fixture assembly, said clamping fixture assembly comprising:
- a body having a predetermined length extending between a head receiving end and a fastener receiving end, said body defining a hollow core extending between said head receiving end and said fastener receiving end;
- a fastener port disposed at said fastener receiving end for receiving a fastener therein;
- and
- an access opening in said body between said head receiving end and said fastener receiving end, said access opening providing access to said hollow core along said defined length allowing measurements of the test piece to be taken while the test piece is secured to said clamping fixture assembly.
