Plastics - Unsaturated polyester resins - Determination of acid value
inactive
| Organization: | NEN |
| Publication Date: | 1 April 1978 |
| Status: | inactive |
| ICS Code (Thermosetting materials): | 83.080.10 |
scope:
This International Standard specifies a methode of determining the acid value of unsaturated polyester resins. In some cases, notably when free anhydrides are present, a somewhat lower than theoretical acid value is found, due to the formation of acid esters which precipitate and are, therefore, not determined.
