Significance and Use | ||
4.1 This test method is used to determine the property of ester functionality. Ester functionality determines the utility of the wax as well as being a significant quality control test. |
||
1. Scope | ||
1.1 This test method covers the determination of the saponification number of synthetic waxes and natural waxes. 1.2 This test method is applicable to Fischer Tropsche, microcrystalline, polyethylene, and Montan Ester waxes. 1.3 Certain synthetic waxes, notably copolymers of ethylene, exhibit poor reproducibility when running saponification values. Reproducibility can be improved if cooking time in 1.4 Some oxidized polyethylene and other waxes with a melt temperature above 100°C may give poor reproducibility. 1.5 Some dark-colored (Gardner Color 14) waxes may obscure the color change of the indicator, resulting in poor reproducibility. 1.6 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.7 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. |
