Doplňující informace
| 1. Scope | ||||||||||||||||||||||||||||||

1.1 This classification system covers polychlorotrifluoroethylene (PCTFE) plastics that consist of at least 90 % chlorotrifluoroethylene and are suitable for extrusion and for compression and injection molding. Additional components allow for chemical modifications, such as co-monomers, but not colorants, fillers, plasticizers, or mechanical blends with other resins. This classification system does not cover recycled PCTFE materials. 1.2 The physical and electrical properties of parts molded or extruded from PCTFE molding compounds vary with the crystalline content obtained during processing and subsequent annealing. Accordingly, the numerical values listed in Table 1 apply only to the test specimens molded in accordance with Section 8. These values are not applicable as design criteria to semi-finished and finished parts prepared and annealed under other conditions. 1.3 The values stated in SI units as
detailed in IEEE/SI-10 are to
be regarded as the standard. The values given in parentheses are
for information only.
1.4 The following precautionary statement pertains only to the test methods portion, Section 10, of this classification system: Note 1: Although this classification system and ISO 12086-1 (1995) and ISO 12086-2 (1995) differ in approach or detail, data obtained using either are technically equivalent. |
