230.3—20XX標(biāo)定的標(biāo)準(zhǔn)硬度塊進(jìn)行間接檢驗(yàn)。如果在此溫度范圍以外檢驗(yàn)，應(yīng)在檢驗(yàn)報(bào)告中注明。 5.2 程序 5.2.1 硬度計(jì)的間接檢驗(yàn)應(yīng)按照以下程序執(zhí)行。應(yīng)對(duì)硬度計(jì)使用的每一個(gè)標(biāo)尺進(jìn)行檢驗(yàn)。對(duì)于每一個(gè)待檢驗(yàn)的標(biāo)尺，應(yīng)使用表1中規(guī)定的每一個(gè)硬度范圍的標(biāo)準(zhǔn)塊。標(biāo)準(zhǔn)塊的硬度值應(yīng)接近預(yù)期使用的極限值。建議采用與標(biāo)定標(biāo)準(zhǔn)硬度塊時(shí)相同的試驗(yàn)循環(huán)時(shí)間。試驗(yàn)時(shí)只允許使用標(biāo)準(zhǔn)硬度塊的標(biāo)定面。
