1 Scope

This standard specifies the method for determination of animal fat in polyethylene polymers. This standard applies to the determination of animal fats in particular polyethylene polymers. This standard does not apply per kilogram of polymer samples containing less than 50mg of the sample (see Table A.1 result of tallow 1).

2 Terms and definitions

The following terms and definitions apply to this standard. 2.1 Soluble in boiling tetrachlorethylene impurities. For example. polyethylene packaging materials. Principle 3 It will be broken down by the acid soaps compounds tested sample was dissolved in chloroform (polyethylene polymer suspended in solution), with the use of The sand core has a filter aid layer of filter crucible. Flushing the crucible and the insoluble matter was dried and weighed. Then boiling tetrachlorethylene, polyethylene-based polymer It was extracted from the insolubles. The crucible and insolubles again dried and weighed.

4 Reagents
