This International Standard specifies a method for the determination of the plane-strain crack-arrest fracture toughness, K<\/i>la<\/sub>, of polymeric materials by using a side-grooved, crack-line-wedge-loaded compact tension specimen to obtain a rapid crack run-arrest segment of flat-tensile separation with a satisfactory crack front. This International Standard employs a static fracture analysis determination of the stress intensity factor at a short time after crack arrest. The estimate is denoted as K<\/i>a<\/sub> and when certain size requirements are met, the test result provides an estimate, termed as K<\/i>la<\/sub>, of the plane-strain crack-arrest toughness of the polymer. The specimen size requirements provide for in-plane dimensions large enough to allow the specimen to be modelled by linear elastic analysis. If the specimen does not exhibit rapid crack propagation and arrest, K<\/i>a<\/sub> cannot be determined.<\/p>\n
