GUIDELINES ON DECISION RULE  
 
This document will provide the decision rule that will be used to account for measurement 
uncertainty, based on ILAC -G8:09/2019.  
 
Definition of Terms:  
 
Acceptance Interval - interval of permissible measured quantity values.  
 
Acceptance Limit (AL)  - specified upper or lower bound of permissible measured 
quantity values.  
 
Guard Band (w)  – interval between a tolerance limit (TL) and a corresponding 
acceptance limit (AL) where length w = |TL – AL|. 
 
Measured Quantity Value  - quantity value representing a measured result.  
 
Rejection Interval  - interval of non -permissible measured quantity values.  
 
Specific Risk - is the probability that an accepted item is non -conforming, or that a 
rejected item does conform. This risk is based on measurements of a single item . 
 
Tolerance Interval / Specification Interval  - interval of permissible values of property.  
 
Tolerance Limit (TL) / Specification Limit - specified upper or lower bound of 
permissible values of a property.  
 
Decision Rule  
 
A Binary decision rule is when the result is limited to two choices (pass or fail). As explained 
below, the declaration of conformity is binary acceptance.  
 
 Binary Acceptance based on Guard Band  
 
 The decisions are based on guard -banded acceptance limits. The acceptance limits, AL = TL 
– w, where U is the expanded measurement uncertainty or equivalent to w. The estimate of 
the measurand is assumed to have a normal probability  distribution and specific risk is used 
for the risk calculation. In this case, the risk of accepted items being outside the tolerance limit 
is less than or equal to 2.5%.

Statements of Conformity are reported as follows:  
• Pass – acceptance based on guard band; the measurement result being below the 
acceptance limit, AL = TL – w.  
• Fail – rejection based on guard band; if the measurement result is above the 
acceptance limit, AL = TL – w
