7.試樣斷裂時的伸長率（扯斷伸長率）。二、根據(jù)以上所測參數(shù)的要求。橡膠拉伸試驗(yàn)過程中需要**的數(shù)據(jù)有兩項(xiàng)：拉力力值和標(biāo)距變化量。所以用于測試橡膠拉伸性能的橡膠拉力試驗(yàn)機(jī)必須滿足以下四個要求：1.大行程。由于橡膠在拉伸時變形量很大，尤其是乳膠制品，伸長率有可能高達(dá)1000%以上。所以在橡膠試樣斷裂之前，必須保證夾持器有足夠的行程。2.高精度及高頻率的數(shù)據(jù)采集。拉伸橡膠不需要很大的力，拉力測量范圍不需要很大，所以需要力值的精度較高。一般要求測力儀，拉力機(jī)，硫化儀能夠求取小數(shù)點(diǎn)后兩位以上精度的力值。此外由于檢測橡膠拉伸性能需要拉伸過程中的數(shù)個拉力值，而拉伸試驗(yàn)又不可重復(fù)，所以即時準(zhǔn)確記錄每個試驗(yàn)段的拉力力值對于試驗(yàn)成敗起著非常重要的作用。3.準(zhǔn)確的標(biāo)距測量和記錄裝置（如圖）。試樣標(biāo)距的測量是計算橡膠伸長率的重要數(shù)據(jù)，所以橡膠拉伸試驗(yàn)中拉力試驗(yàn)機(jī)必須準(zhǔn)確地測量試樣的應(yīng)變量，并即時地記錄下來。4.可以準(zhǔn)確描述應(yīng)力－應(yīng)變曲線的裝置。拉伸試樣中的拉力值和標(biāo)距之間有著密切的聯(lián)系，例如：試樣的定伸應(yīng)力需要測量試樣拉伸到給定伸長率的力值，而定應(yīng)力則需要測量試樣拉伸到給定應(yīng)力的標(biāo)距。試驗(yàn)完成后。安徽動態(tài)疲勞試驗(yàn)機(jī)</p><p
