Abstract
The present invention relates to an elastomeric material thickness test fixture. The test fixture comprises a cylinder having an interior space for receiving at least one sheet of a material to be tested, and a piston movable relative to the cylinder for applying a holding force to the at least one sheet. The piston has a through hole to allow a test medium to be used to study chemical attack to come into contact with the at least one sheet. A process for allowing assessment of chemical attack on thick elastomeric materials using the test fixture is also described.
Claims10
A test fixture for testing sheets of material comprising:
- a cylinder having a side wall and a bottom surface defining an interior space for receiving at least one sheet of material to be tested;
- a piston slidable within said cylinder, said piston and said cylinder bottom surface cooperating for applying a holding force to said at least one sheet, said piston having a through hole for allowing a test medium to come into contact with said at least one sheet;
- and
- means for applying force joined between said piston and said cylinder for applying a force to said piston and causing said piston maintain a position within said cylinder and into a position where said piston contacts a surface of said at least one sheet.
A test fixture for testing sheets of material comprising:
- a cylinder having a side wall and a bottom surface defining an interior space for receiving at least one sheet of material to be tested;
- a piston having a flange positioned exterior of said cylinder and a body portion slidable within said cylinder, said flange and body portion defining a through hole inside said piston, and said piston body portion and said cylinder bottom surface cooperating for retaining said at least one sheet therebetween;
- a sealing means positioned between said cylinder side wall and said piston body portion;
- and
- a fastening means joined between said piston flange and said cylinder side wall for retaining said piston within said cylinder.
A process for allowing the assessment of chemical attack on thick elastomeric materials comprising:
- providing a cylinder having an interior space;
- positioning at least one sheet of elastomeric material within said interior space;
- fastening a piston with a through hole within said cylinder for retaining said at least one sheet of elastomeric material within said interior space;
- and
- immersing said cylinder with said at least one sheet and said piston into a test medium in which said chemical attack will be assessed.
