Tack - The ability to adhere to itself; a sticky or adhesive quality.
Team Feasibility Commitment - A commitment by the Product Quality Planning Team that the design can be manufactured, assembled, tested, packaged, and shipped in sufficient quantity at an acceptable cost, and on schedule.
Tear Resistance - Resistance to tearing, measured as the force required to tear completely across a specially-designed nicked rubber test piece or right-angled test piece by elongating it at a specified rate. Express in lbs. per inch of thickness of specimen.
Tear Strength - The maximum load required to tear apart a specified specimen, the load acting substan- tially parallel to the major axis of the test specimen.
Telescopic Packing - Packing sets used on telescopic cylinders, each stage having a different diameter.
Temperature Range - Lowest temperature at which rubber remains flexible and highest temperature at which it will function.
Tensile Strength - Force in pounds per square inch required to cause the rupture of a specimen of a rubber material.
Tensile Strength - The capacity of a materiel to resist a force tending to stretch it. Ordinarily the term is used to denote the force required to stretch a material to rupture, and is known as "breaking load", "breaking stress "ultimate tensile strength". lit rubber testing, it is the load in lbs. per square inch or kilos per square centimeter of original cross-sectional area, supported at the moment of rupture by a piece of rubber being elongated at a constant rate.
Tensile Stress - The applied force per unit of original cross sectional area of a specimen.
Tensile Stress at Given Elongation - The tensile stress required to stretch a uniform section of a specimen to a given elongation.
Tension Set - The extension remaining after a specimen has been stretched and allowed to retract.
Thermal Deterioration - The elongation at the moment of rupture.
Thermoplastic Rubber - Rubber that does not require chemical vulcanization and will repeatedly soften when heated and stiffen when cooled; and which will exhibit only slight loss of its original charac- teristics.
Thermosetting Rubber - Chemi- cally vulcanized rubber that cannot be remelted or remolded without destroying its original characteristics.
Thorseals - A brand name for a polyurethane hydraulic u-cup seal.
Timing Plan - A plan that lists tasks, assignments, events, and timing required to provide a product that meets customer needs and expec- tations.
Tips - A rubber cup-shaped part used on the end of a rod or shaft to provide shock resistance or cushioning.
Trim - The process Involving removal of mold flash.
T-Seals - A "T" shaped rubber sealing ring with harder back-up rings on each side for rod or piston sealing.
Tube Springs - A rubber or plastic cushioning device used to assist spring or cover the outer portion of a coil spring.
