Yoriqhosilbo’lgandan keyin, qiyayoriqni kengayishini mikroskop MPB-2 yordamida aniqlanadi. To’sinni oklangan yuzasida poydo bo’lganyoriqlar urni kalam bilan chizib borilada va tajriba oxirida masshtab turida yoriqlar kartasi tuziladi. Priborlardan olingan hisoblarga kura buzilish vaqtidagi ko’ndalang kuchning tajribaviy qiymati aniqlanadi.
Tajribadan olingan natijalarni nazariy hisoblar bilan takkoslanadi va to’sinni yarokliligi to’g’risida xulosa chikariladi.
