18661-2 quantize has
  Nothing about non-canonical encodings.  
  Nothing about overflow.
  Nothing about 'invalid' (which would be in Annex F).
754 has in 5.3.2
 ...this operation shall not propagate non-canonical encodings:
 quantize does not signal underflow or overflow.
 Otherwise if only one operand is infinite then the invalid operation
 exception is signaled and the result is a NaN.

18661-2 llquantexp has
  Nothing about 'invalid' for infinite and NaN (which would be in Annex F).
