Organization: ASTM International
Publication Date: 10 July 1998
Status: inactive
Page Count: 2
ICS Code (Auxiliary materials and additives for plastics): 83.040.30
ICS Code (Thermoplastic materials): 83.080.20
scope:

1.1 These test methods determine the viscosity of crude or modified iso cyanates. It is applicable to products derived from toluene di iso cyanate, methylene-bis-(4-phenyl iso cyanate), and polymethylene polyphenyl iso cyanates. (See Note

1.)

1.2 This standard does not purport to address all of the safety problems, 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 statements see Note 2 and 10.5.

Note 1-There is no equivalent ISO standard.
