This study was evaluated the penetration performance according to SPM type. The types of SPM are liquid and cream type. And the amounts of SPM were applied 0.13, 0.25, 0.36, and 0.51 kg/㎡. The specimen size was 100×30mm as KS F 4930. Test results indicated that the penetration depth of SPM were improved with increasing the amounts of application of liquid and cream SPM. In the case of applied cream SPM of 0.13, 0.25 and 0.36 kg/㎡ the standard deviation of penetration depth was less the liquid type SPM was applied.
