A measure of the force required to continue a tear in a foam after a split or break has been started and expressed in pounds per inch (lbs/in.). This property is important in determining suitability of foam in applications where the material is sewed, stapled, or otherwise anchored to a solid substrate. Also important in demoldability. (ASTM D3574).
The force required beginning, or continuing a tear in a fabric under specified conditions.
The force required to propagate a tear already initiated by a cut on the edge.
The property of a material that is measured by the force required to tear it under specified conditions.
The amount of pressure, in pounds, necessary to tear material.
The ability of a piece of flexible polyurethane foam to resist propagation of a cut made in the sample. Reference ASTM D-3574
the capacity of a compound to resist the initiation of a break in its surface or the propagation of such a break; several kinds of tear tests exist, but close correspondence of any of them to field experience has not been established
A measure of the force necessary to continue a tear in a material once a tear has been started. With most elastomers, the Die B test (___) is used, and the measurement is made in units of pounds per inch (ppi).
The force required to initiate or continue a tear in a material under specified conditions
The force required to propagate a tear in a silicone which has been nicked or cut. Expressed in lbs./in. of width.
The maximum force required to tear a specimen.
The load required to tear apart a sealant specimen. ASTM test method D-624 expresses tear strength in pounds.
The maximum load required to tear apart a specified specimen, the load acting substantially parallel to the major axis of the test specimen.
The force required to start or continue or propagate a tear in a geotextile under specified conditions.
The force required to tear a specimen under standardized conditions in an instrument designed to simulate in a general way the tearing encountered under use conditions.
The resistant property of a sheet of paper to tearing, usually measured by the force required to tear a strip under standard conditions.
Property measured by the force required to tear a specimen under specified test conditions.
