  • väikeste koormustega (tavaliselt alla 2 N) materjali kõvaduskatse (Vickersi, Knoopi jt meetodid) (vt: mikrokõvadus, Knoopi kõvadus, Vickersi kõvadus; vrd makrokõvaduskatse)
  • a microindentation hardness test (such as Knoop or Vickers hardness test) using a calibrated machine to force a diamond indenter of specific geometry, under a test load of 1 to 1000 g force into the surface of the test material and to measure the diagonal or diagonals optically (see: microhardness, Knoop hardness, Vickers hardness; compare: macrohardness test)

microhardness test preferred
  • mehaanilise kõvaduskatse, mida kasutatakse eriti väga rabedate materjalide või õhukeste lehtede puhul
  • kõvaduskatse, mille korral kasutatakse püramiidikujulist indentorit mille pikkuse laiuse suhe on 7:1
  • test for mechanical hardness used particularly for very brittle materials or thin sheets
mikrokõvaduskatse preferred
Usage examples
  • Mikrokõvaduskatse korral surutakse püramiidikujuline teemantsüvend katsekeha pinnale, kasutades teadaolevat rakendatavat jõudu 1 N kuni 10 N, ja tekitatakse kuni 50 μm süvendid.

Usage examples
  • In microhardness test, a diamond indenter of specific geometry is impressed into the surface of the test specimen using a known applied force of 1 N to 10 N and produce indentations of about 50 μm.
