Scope
This International Standard specifies a method of determining the average molecular mass and the molecularmass
distribution of raw natural rubber dissolved in tetrahydrofuran. A set of polystyrene standards is used for
calibration purposes (i.e. the method is a relative one).
An alternative method, using cyclohexane as solvent and polyisoprene standards, is included in an informative
annex.
