D If asym speci? Five specimens shall be tested. The dissipation factor is the cotangent of the dielectric phase angle or the tangent of the dielectric loss angle.
NOTE 21—Physical properties of most nylon resins are highly dependent upon the moisture content of the molded item. The test specimen is a disk Recommended processing temperatures are shown in Table 3. This standard does not purport to address all of the safety concerns, if any, associated with its use. Suffix values will override the PA table values. These specimens shall be tested. J Carbon black content and absorbance must be 1.
Material data for inje Your comments will receive d40066 consideration at a meeting of the responsible technical committee, which you may attend. G Relative Viscosities for Group 03 were generated from a correlation with Test Method Dutilizing an Ubbelohde viscometer, and m-Cresol as the solvent.
