Plastics — Polyurethane raw materials — Determination of isocyanate content - Third Edition
N 14896
Annotation
This lnternational Standard specifies two methods for the measurement of the isocyanate content of aromatic isocyanates used as polyurethane raw materials. Method A is primarily applicable to refined toluene diisocyanate (TDI), methylene-bis-(4-phenylisocyanate) (MDI) and their prepolymers. Method B is applicable to refined, crude or modified isocyanates derived from toluene diisocyanate, methylenebis-( 4-phenylisocyanate) and polymethylene polyphenylisocyanate. It can also be used for isomer mixtures of toluene diisocyanate, methylene-bis-(4-phenylisocyanate) and polymethylene polyphenylisocyanate. Other aromatic isocyanates may be analysed by this method if precautions are taken to verify suitability. It is not applicable to blocked isocyanates.

Пластмассы — сырье Полиуретана — Определение содержания изоцианата - Третий Выпуск
Этот международный Стандарт определяет два метода для измерения содержания изоцианата ароматических изоцианатов, используемых в качестве сырья полиуретана. Метод A прежде всего применим к очищенному диизоцианату толуола (TDI), метилену еще раз - (с 4 фенилизоцианатами) (MDI) и их форполимеры. Метод B применим к усовершенствованным, сырым или измененным изоцианатам, полученным из диизоцианата толуола, methylenebis-(с 4 фенилизоцианатами) и полиэтилен polyphenylisocyanate. Это может также использоваться для смесей изомера диизоцианата толуола, метилена еще раз - (с 4 фенилизоцианатами) и полиэтилен polyphenylisocyanate. Другие ароматические изоцианаты могут быть проанализированы этим методом, если меры предосторожности приняты для проверки пригодности. Это не применимо к блокированным изоцианатам.
