Radiance temperature (at 653nm) of iron at its melting point was measured using a subsecond-duration pulse heating technique. Specimens in the form of strips with initially different surface roughnesses were used. The results do not indicate any dependence of radiance temperature (at the melting point) on initial surface or system operational conditions. The average radiance temperature (at 653 nm) at the melting point for 13 specimens is 1670 K on IPTS-68, with a standard deviation of 0.8 K and a maximum absolute deviation of 1.7 K. The total error in the radiance temperature is estimated to be not more than ±6 K.
采用亚秒级持续时间脉冲加热技术测量了铁在熔点时的辐射温度（653纳米处）。使用了初始表面粗糙度不同的条状试样。结果并未表明辐射温度（熔点时）对初始表面或系统运行条件有任何依赖性。13个试样在熔点时的平均辐射温度（653纳米处）在国际实用温标（IPTS - 68）下为1670K，标准偏差为0.8K，最大绝对偏差为1.7K。辐射温度的总误差估计不超过±6K。
