Description of key information

Viscosity is an inherent property of the liquid and is a measure of the resistance of a fluid which is being deformed by either shear stress or tensile stress. Since methyl 5-nitrohydrogen.isophthalate is a solid measurment of its viscosity was not considered to be technically feasible and hence for this end point a waiver was claimed.

Key value for chemical safety assessment
