(This is a re-do of an inquiry sent Friday, in case it went nowhere.  I've 
received
no replies and we had a mail-server problem, so I thought I'd try again)

I've been tasked with justifying the enforcement of a long established
internal requirement, here at PBNI.   For as long as I can recall, we have
been considering solder flagging (aka icicles, solder spikes) a rejectable
condition, even when a solitary occurrence of as little as 0.8 mm.
(We based this rejection upon workmanship standards that we adopted
from a sister organization with a much more Class 3 and military 
orientation).

As we are manufacturing Class 2 products, and are re-evaluating the adopted
requirements, this 'reject' comes into question. I'm reviewing 
ANSI/J-STD-001A
and IPC-A-610B this morning, I find no reference to this condition other 
than
that shown in Figure 4-17 of the latter.

I certainly don't object to loosening up on our present standard if it is 
not
justifiable, but I can't help the feeling that I'm missing something.  Am I 
?

An anticipatory  ...Thanks !
