| Organization: | NEN |
| Publication Date: | 1 April 1989 |
| Status: | inactive |
| ICS Code (Thermoplastic materials): | 83.080.20 |
scope:
This part of ISO specifies a method for determining the viscosity number of dilute solutions of poly(ethylene terephthalate), poly(butylene terephthalate) and copolymers of the two. With poly(ethylene terephthalate) a mixture of 1 part by mass of phenol and 1 part by mass of 1,2-dichlorobenzene is used as solvent. With the other polymers m-cresol is used as solvent.
