Standard Test Method for Instrumented Impact Testing of Metallic Materials
N E2298
Annotation
This test method establishes the requirements for performing instrumented Charpy V-Notch (CVN) and instrumented Miniaturized Charpy V-Notch (MCVN) impact tests on metallic materials. This method, which is based on experience developed testing steels, provides further information (in addition to the total absorbed energy) on the fracture behavior of the tested materials. Minimum requirements are given for measurement and recording equipment such that similar sensitivity and comparable total absorbed energy measurements to those obtained in Test Methods E23 and E2248 are achieved.
The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
*A Summary of Changes section appears at the end of this standard
Автоматический перевод:
Метод стандартной пробы для инструментованного испытания на удар металлических материалов
Этот метод испытаний устанавливает требования для выполнения инструментованной V-метки Charpy (CVN) и инструментованных испытаний на ударную вязкость Миниатюризированной V-метки Charpy (MCVN) на металлических материалах. Этот метод, который основан на опыте, развитом, проверяя стали, предоставляет дополнительную информацию (в дополнение к общей поглощенной энергии) на поведении перелома проверенных материалов. Минимальные требования даны для оборудования измерения и регистрирующего оборудования, таким образом, что подобная чувствительность и сопоставимые общие измерения поглощенной энергии к полученным в Методах испытаний E23 и E2248 достигаются.
