山本科學(xué)硬度塊

日本山本科學(xué)社YAMAMOTO硬度塊

　　在所有硬度測(cè)試中，測(cè)量通過(guò)對(duì)樣品施加測(cè)試力（力）而產(chǎn)生的變形量（長(zhǎng)度）。從這個(gè)意義上說(shuō)，硬度的標(biāo)準(zhǔn)取決于力和長(zhǎng)度和時(shí)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(duì)硬度變化極小、硬度不隨時(shí)間變化的試片進(jìn)行測(cè)試，并顯示硬度值。

　　用于對(duì)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)。
