This International Standard specifies a method for the laboratory preparation of a paste from PVC paste resins under controlled conditions.
This paste can be used for the control (in particular, of the rheological properties) and comparison of resins.
NOTES
1 For certain studies and in particular those concerning application problems, other methods using different apparatus and formulae can be used (for example with stabilizers).
2 The method shall not be used if the relative humidity is equal to or less than 20 % as anomalous results can be obtained in such cases.
