This standard 20/30409960 DC BS ISO 16152. Plastics. Determination of xylene-soluble matter in polypropylene is classified in these ICS categories:

• 83.080.01 Plastics in general

This international standard specifies a method of determining the mass fraction of a polypropylene homopolymer of copolymer which is soluble in xylene at 25°C.

Other materials with solubilities similar to that of the xylene-soluble fraction, such as additives, may interfere with the determination.

This international standard included two methods which are “reference method (method 1)”and “automated instrument method (method 2)”, The “reference method” is used to calibrate the method used for the determination of the xylene-soluble matter in polypropylene.

The “automated instrument method” is a method which can be used for the determination if it is calibrated using the reference method described in clause 4 provided it shows a certain permissible repeatability.
