1.1This test method determines the ratio of the infrared absorbance of uretidinedione (dimer) in methylene-4,4’- di(phenylisocyanate) to an infrared absorbance at a reference wavelength within the same material. It is applicable to monomeric methylene-di(phenylisocyanate), or “Pure MDI,” containing 95 % or greater methylene-4,4’-di(phenylisocyanate).
1.2This 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:There is no known ISO equivalent to this standard.
