Oxidation on termination of smd chip capacitor | 19 April, 2007

I observed some black dot or some oxidation occured on chip termination on pcba reflowed fews weeks ago as buffer stock. The solder joint and fillet wetting is good and shinning. It is an acceptable or defect condition per IPC standard/requirement? Which IPC standard tell the acceptability?
