ASTM D256塑料耐沖擊性測定的標(biāo)準(zhǔn)試驗方法
ASTM D256 Standard Test Methods for Determining the Izod Pendulum Impact Resistance of Plastics
ASTM D256塑料耐沖擊性測定的標(biāo)準(zhǔn)試驗方法簡介:此方法包含了安裝在標(biāo)準(zhǔn)設(shè)備上的標(biāo)準(zhǔn)擺錘度對塑料耐沖擊性能的測定。ASTM E256標(biāo)準(zhǔn)測試的測試方法要求樣本有一缺口。在測試方法A,C和D中,缺口集中產(chǎn)生應(yīng)力從而增加了脆性而不是韌性和斷裂的可能。
ASTM D256 Standard Test Methods for Determining the Izod Pendulum Impact Resistance of Plastics scope: These test methods cover the determination of the
resistance of plastics to “standardized” pendulumtype hammers, mounted in “standardized” machines, in breaking standard specimens with one pendulum swing . The standard tests for these test methods require specimens made with a milled notch . In Test Methods A, C,and D, the notch produces a stressconcentration that increases the probability of a brittle, rather than a ductile, fracture.
