Compliance assessment

15/05/2021,

Is the tested item/product compliant with the (i) minimum limit "mL", (ii) maximum limit "ML",

or (iii) both/range, set by the legislation or the technical specifications?  Try the worksheet below:
Introduce your measurement "Result"  expressed in "unit";

• Select the level of maximum risk ("LMR" = 5 %, or 1 % for zero tolerance);
• Provide the expected "Target relative expanded uncertainty",  and the relative expanded uncertainties "RU (k=2),%" you expect
  @ "mL" and "ML" (can be the same value); and
  
• Specify the minimum and/or Maximum Limits ("mL", "ML");

Your result will be assessed for conformance according to three risk categories:

• producer's risk: risk of a false rejection of the analysed product
• consumer's risk: risk of a false acceptance of the analysed product
• consumer & producer share the risk of a false acceptance or a false rejection of the analysed product

Acceptance limits (AL) calculated as follows:

   Lower Producer's AL = mL-(gb*mL*RU@mL/2)

   Lower Shared AL     = mL

   Lower Consumer's AL = mL+(gb*mL*RU@mL/2)

   Upper Consumer's AL = ML-(gb*ML*RU@ML/2)

   Upper Shared AL     = ML

   Upper Producer's AL = ML+(gb*ML*RU@ML/2)

where "gb" is the Guard Band (gb = 1.64 when LMR = 5 %; gb = 2.33 when LMW = 1 %).
