7.5.3 按規(guī)定的初試驗力保持時間tPF 保持初試驗力。 </p> <p> 7.5.4 初試驗力保持時間tPF 結(jié)束時，立即確定壓痕基準(zhǔn)深度的參照位置（見生產(chǎn)廠商的使用說明書）。 </p> <p> 7.5.5 將試驗力增加F1 即主試驗力，達到選定的硬度標(biāo)尺所需的總試驗力F（見表1 和2）。主試驗 </p> <p> 力Fl 應(yīng)在規(guī)定加載時間范圍tTA 之內(nèi)可控地加載。 </p> <p> 7.5.6 按規(guī)定的總試驗力保持時間tTF 保持總試驗力F。 </p> <p> 7.5.7 繼續(xù)保持初試驗力F0 的同時，卸除主試驗力F1。 </p> <p> 7.5.8 將初試驗力F0 保持適當(dāng)時間，使被測材料彈性恢復(fù)，并且框架的拉伸變得可以忽略不計。 </p> <p> <br /> </p> <p> <br /> </p> <p> <br /> </p><p> 5.5.1 一般的試樣支撐裝置的硬度應(yīng)不小于58HRC。有些特殊支撐砧座要求更低的材料硬度。 </p> <p> 5.5.2 平面試樣應(yīng)在具有光滑、平坦支撐面的平砧座上進行測試，其平面垂直于壓頭的軸線。 </p> <p> ASTM E18-2017?1

對于薄材料或非完全平面試樣，應(yīng)使用一個帶有3mm(1/8in.)~12.5mm(1/2in.)直徑凸起平在“點” </p> <p> 的砧座，該點應(yīng)被打磨光滑平整。非常軟的材料不能在“點”砧座上進行測試，因為無損試樣厚度 </p> <p> 大小，施加的力都可能會導(dǎo)致砧座被壓入試樣的底面。 </p> <br /> <p> <br /> </p> <p> <br />
