The notion of normality of codes in Hamming metric is extended to the codes in Rosenbloom-Tsfasman metric (RT-metric, in short). Using concepts of partition number and l -cell of codes in RT-metric, we establish results on covering radius and normality of q -ary codes in this metric. We also examine the acceptability of various coordinate positions of q -ary codes in this metric. And thus, by exploring the feasibility of applying amalgamated direct sum method for construction of codes, we analyze the significance of normality in RT-metric.
