ASTM D4889-04-Reapproved2011<\/h3>\n

Historical Standard: Standard Test Methods for Polyurethane Raw Materials: Determination of Viscosity of Crude or Modified Isocyanates<\/h4>\n
\n

ASTM D4889<\/h4>\n

Scope<\/strong><\/p>\n

1.1 These test methods (A and B) determine the viscosity of crude or modified iso<\/span>cyanates. They are applicable to products derived from toluene diiso<\/span>cyanate, methylene-bis-(4-phenyliso<\/span>cyanate), and polymethylene polyphenyliso<\/span>cyanates (see Note 1).<\/p>\n

Note<\/span> 1\u2014Test method A includes a procedure for measuring dynamic viscosity using a rotational Brookfield instrument. Test method B is simply a reference to a general procedure for measuring kinematic viscosity using a Cannon-Fenske instrument, D445.<\/p>\n

1.2 The values stated in SI units are to be regarded as standard.<\/p>\n

1.3 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.<\/span> For specific hazards statements see Warnings<\/span> at the end of 5.1 and 10.5.<\/p>\n

Note<\/span> 2\u2014There is no known ISO equivalent to this standard.<\/p>\n
