I'm researching approvals for a weight transmitter and have come across a data sheet that doesn't give specific approvals names, only the types of areas they're approved for. Does anyone know what FM/ANSI/ISA approvals these correspond to?

Intrinsically Safe, Class 1-3, Division 1, Group A-G
Intrinsically Safe, Class 1, Zone 0, AEx ia IIC
Nonincendive Class 1, Division 2, Group A-D
Nonincendive Class 1, Zone 2, Group IIC
S Class 2-3, Division 2, Group F-G
T4 (Ta = 50C)


Thanks in advance!
