Isocyanates
ASTM D5836 and OSHA 42 are test methods for determining
2,4-toluene diisocyanate (2,4-TDI) and 2,6-TDI in the work-
place atmosphere. OSHA 47 is for 4,4
'
-methylenediphenyl
isocyanate (4,4
'
-MDI) in indoor air, and NIOSH Method 5522
is for 2,4-TDI; 2,6-TDI; 4,4
'
-MDI; and 1,6-hexamethylene
diisocyanate (1,6-HDI) in air. Restek offers the 1-(2-pyridyl)
piperzine (1-2pp) derivative.
