Strength at Yield (Tensile)

Tensile strength (TS) at yield, sometimes called tensile stress at yield, measures the stress a plastic can withstand at the yield point, i.e. when an increase in strain is not provoked by an increase of stress.

In the International System, the unit of Tensile Strength is the pascal (Pa) (or megapascals, MPa or even GPa, megapascals), which is equivalent to newtons per square meter (N/m2). In the US, pounds-force per square inch (lbf/in2 or psi), or kilo-pounds per square inch (kpsi) are commonly used for convenience when measuring tensile strengths.

ASTM D638 and ISO 527 are the standards commonly used to measure the tensile properties of plastics.
