Deviation Analysis

IEC 61882 Guide Words:
• MORE/LESS: Quantitative increase/decrease
• NO/NONE: Complete negation of intent
• REVERSE: Opposite direction or action
• PART OF: Incomplete or missing component
• AS WELL AS: Additional (contamination)
• OTHER THAN: Different from intended
• EARLY/LATE: Timing deviation
