Authors could obtain yield values of 25 sorts of waxes with much more accuracy ahd rapidity. As the results, the correlation, between yield value and needle penetration number of waxes which was presented in the previous paper as equation (9), was revised as equation (3) of the present paper.
In addition, viscosity of waxes were estimated from tangent at yield value of correlating relationship between rate of penetration and shearing stress at the apex of the needle.
