1.1These test methods determine the specific gravity of toluenediisocyanate, polymeric (methylene phenylisocyanate), and liquid methylene di(phenylisocyanate). These test methods also are applicable to many other liquids. (See Note 1.)
1.1.1Test Method A—Specific gravity by pycnometer, for high-accuracy determination.
1.1.2Test Method B—Specific gravity by hydrometer, for a less accurate, but rapid, determination.
1.2The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.3This 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
Note 1:There is no known ISO equivalent to this standard.
1.4This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
