NEN-ISO 8328
Amorphous thermoplastic moulding materials - Determination of maximum reversion
| Organization: | NEN |
| Publication Date: | 1 August 1990 |
| Status: | inactive |
| ICS Code (Thermoplastic materials): | 83.080.20 |
scope:
This International Standard specifies a method of assessing molecular orientation in test specimens of amorphous thermoplastic materials by determination of the maximum longitudinal reversion after a specified heat treatment. The method is suitable only for specimens exhibiting predominantly uniaxial orientation, such as bars and dumb-bells in which the orientation occurs along the length of the specimen, or plates in which the orientation is parallel to one of the sides.
