日本山本科學(xué)社YAMAMOTO硬度塊
在所有硬度測試中，測量通過對樣品施加測試力（力）而產(chǎn)生的變形量（長度）。從這個意義上說，硬度的標(biāo)準(zhǔn)取決于力和長度和時間等直接精度。
硬度基準(zhǔn)片是直接精度特別優(yōu)異的試驗(yàn)機(jī)，對硬度變化極小、硬度不隨時間變化的試片進(jìn)行測試，并顯示硬度值。
用于對試驗(yàn)機(jī)進(jìn)行日常檢查（間接精度），確認(rèn)試驗(yàn)機(jī)是否在標(biāo)準(zhǔn)規(guī)定的允許范圍內(nèi)（非校準(zhǔn)）。因此，如果在使用基準(zhǔn)件的檢查中發(fā)現(xiàn)任何異常，將由專家等進(jìn)行直接的精度檢查和校準(zhǔn)。
