红外吸收法测碳钢中碳含量的不确定度评定

Evaluation of Uncertainty for Determination of Carbon in Carbon Steel by Infrared Absorption Method after Combustion

依据相关检测标准,利用高频红外碳硫分析仪对碳素钢中碳含量进行了测定,列举了对碳含量不确定度有影响的主要因素,并对其不确定度进行了评价,为日后同类型检测中不确定度的评定提供了参考。

According to relevant standard, by using high fr equency infrared carbon-sulfur analyzer, this paper determines carbon content in carbon steel,lists the main factors affecting the uncertainty of carbon content,and evaluates the uncertainty of the determination,providing a reference for the same kind of determination in future.
