231.1測定布氏硬度用的布氏硬度計（以下簡稱硬度計）的直接檢驗和間接檢驗方法，并規(guī)定了應(yīng)對硬度計進行這兩種方法檢驗的檢驗周期。直接檢驗包括檢查被檢硬度計性能參數(shù)是否處于規(guī)定的限值以內(nèi)，而間接檢驗則是使用按GB/T231.3標定的標準硬度塊進行硬度測量來檢查硬度計的綜合性能。如果硬度計還用于其他方法的硬度試驗，則應(yīng)分別按每一種方法單獨對硬度計進行檢驗。本部分適用于固定安裝的硬度計和便攜式硬度計。對于不能符合按規(guī)定的力/時間配置的硬度計，可按附錄B對硬度計的力和試驗循環(huán)時間進行改進的直接檢驗。</p><p style="text-indent:25px">A1.5 定期檢定 A1.5.1 用戶可將定期檢定作為監(jiān)測試驗機在間接檢定周期內(nèi)性能的工具。對于每一個將會使用的努氏和維氏硬度標尺，至少應(yīng)依照表A1.1 中給出的計劃進行定期檢定。 A1.5.2 定期檢定程序—執(zhí)行定期檢定時使用的程序如下： A1.5.2.1 應(yīng)對每個將要使用的維氏和努氏硬度標尺執(zhí)行定期檢定。每個待檢定的維氏和努氏硬度標尺均應(yīng)至少使用一個滿足附錄A4 要求的標定試塊。當(dāng)試塊可從市面上買到時，所選的試塊硬度等級應(yīng)基本與待測材料的硬度值相同。 A1.5.2.2 定期檢定用的壓頭應(yīng)為試驗常用的壓頭。 A1.5.2.3 在進行定期檢定之前，應(yīng)確保試驗機工作正常，工作臺和標定試塊潔凈，并且測量儀器進行了正確的調(diào)整和歸零。 A1.5.2.4 在每個定期檢定用的試塊上至少進行進行硬度試驗，間隔應(yīng)滿足7.11.1 給出的要求。*應(yīng)在試塊校準過的表面進行硬度測量。有洛氏硬度計、電動洛氏硬度計、數(shù)顯洛氏硬度計、數(shù)顯表面洛氏硬度、數(shù)顯洛氏、表面洛氏硬度計。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;"

如壓痕直徑超出了0.24D~0.6D區(qū)間范圍，應(yīng)在試驗報告中注明壓痕直徑與壓頭直徑的比值d/D。針對此項變動，根據(jù)3.1布氏硬度原理以及針對鋼材所推薦采用的F/D2=30比率關(guān)系。d/D=0.24~0.6對應(yīng)的鋼材布氏硬度范圍在95.5~653HBW之間，與ASTM A370鋼鐵產(chǎn)品布氏硬度的規(guī)定類似，即“布氏硬度不建議適用于硬度值高于650HBW的材料，此時壓頭應(yīng)廢棄并更換”。建議CNAS認可實驗室當(dāng)鋼材布氏硬度值在95.5~650HBW區(qū)間范圍以外時，需在報告?zhèn)渥⒅薪o出d/D的具體數(shù)值。并在硬度超出650HBW時立刻檢查壓頭的計量特性或予以更換，以同時滿足GB/T 231.1-2018以及ASTM A370的要求。 (4) 明確了壓痕直徑的光學(xué)測量既可采用手動也可采用自動測量系統(tǒng)，采用自動測量系統(tǒng)時建議對測試表明至少進行磨床處理，有條件時可采用鏡面拋光，以確保對壓痕直徑的準確辨識。 (5) 明確了修約規(guī)則，即保留三位有效數(shù)字，如98.2HBW、220HBW。硬度是表征著材料的彈性、塑性、形變、強化率、強度和韌性等一系列不同物理量組合的一種綜合性能指標。布氏硬度測試儀用途</p><p style="text-indent:25px">用硬度法測試的實況是測試點在黑色的珠光體帶硬度偏高，在白色鐵素體帶硬度偏低。布氏硬度測試儀用途</p><p
