Organization: ASTM International
Publication Date: 1 May 2015
Status: inactive
Page Count: 3
ICS Code (Auxiliary materials and additives for plastics): 83.040.30
ICS Code (Thermoplastic materials): 83.080.20
significance And Use:

4.1 These test methods can be used for research, quality control, or specification tests to characterize isocyanates used in polyurethane products.

4.2 Viscosity measures the... View More

scope:

1.1 These test methods (A and B) determine the viscosity of crude or modified isocyanates. They are applicable to products derived from toluene diisocyanate, methylene di(phenylisocyanate), and polymeric (methylene phenylisocyanate) (see Note 1).

Note 1: Test method A includes a procedure for measuring dynamic viscosity using a rotational instrument. Test method B is simply a reference to a general procedure for measuring kinematic viscosity, D445.

1.2 The values stated in SI units are to be regarded as standard.

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. For specific hazards statement, see Warning at the end of 5.1.

Note 2: This standard is equivalent to ISO 3219 and ISO 3104.
