ASTM D6099
1. Scope
1.1 this test method determines the acidity, expressed as parts per million (ppm) of HCI, in aromatic isocyanate samples of greater than 100-ppm acidity. The test method is applicable to products derived from toluene diisocyanate and methylene-bis(4-phenylisocyanate) (see Note 1).
