ASTM E1012(2019) and ISO 23788(2012) are both available methods based on using strain-gaged alignment transducers for alignment verification of material test machines. It is significant to make known the scope and applications of these standards, as poor alignment adversely affects test results. In this paper, similarities and differences of ASTM E1012(2019) and ISO 23788(2012) are criticized by scanning criteria such as sources of misalignment, configurations of strain-gaged alignment transducers, verification of machine alignment, and determination of alignment class.

对齐验证标准之间差异的回顾研究

ASTM E1012(2019) 和 ISO 23788(2012) 都是基于使用应变片对准传感器对材料试验机进行对准验证的可用方法。了解这些标准的范围和应用非常重要，因为校准不佳会对测试结果产生不利影响。在本文中，ASTM E1012(2019) 和 ISO 23788(2012) 的异同受到了诸如不对中源、应变片对中传感器配置、机器对中验证和对中等级确定等扫描标准的批评。
