1.1 This test method measures unsaturation in polyether polyols.

1.1This test method measures unsaturation in polyether polyols. (See Note 1.) It uses 2 mL of ca. 0.05 M mercuric acetate reagent in methanol and about 1 g of sample or less. This test method uses a potentiometric determination of an end point.

1.2The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

1.3Mercury has been designated by many regulatory agencies as a hazardous substance that can cause serious medical issues. Mercury, or its vapor, has been demonstrated to be hazardous to health and corrosive to materials. Caution should be taken when handling mercury and mercury containing products. See the applicable product Safety Data Sheet (SDS) for additional information. Users should be aware that selling mercury and/or mercury containing products into your state or country may be prohibited by law.

1.4This 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.

Note 1:This standard is equivalent to ISO 17710.
