Metall materiallarning tishli namunalari uchun standart zarba sinov usuli

GB/T229 -2020 metall materiallar charpy zarba sinov usuli va ASTME23 metall materiallar standart zarba sinov usuli farqi va mayatnik ta'sir sinovi qo'llash savol doirasiga e'tibor berish kerak: GB/T229 -2020 aniqlash uchun charpy zarba sinovi yutilish energiya usulida metall materiallar. Bu xona haroratida, yuqori haroratda yoki past haroratda charpy sarkaç ta'sirini sinash uchun javob beradi, lekin asbobli zarba sinov usulini o'z ichiga olmaydi. Ushbu qism uchun GB/T19748 ga qarang. Xona harorati sinovlari uchun atrof-muhit harorati talabi gbt229-2020 23 ± 5 daraja castme23-18 bo'lib, u charpy testi (shunchaki qo'llab-quvvatlanadigan nur) yordamida metall materiallarning tishli namunalarini zarbani sinash usulini belgilaydi. va Isaak Asimov testi (konsol nuri) . Ushbu sinov usuli -196 C (77K) dan past haroratlarda zarba sinovlari uchun mos emas. ASTME{10}} xona haroratida 20 ± 5 daraja
