Description
Compare supplied mass-basis reference-standard potency fractions without assigning assay purity or preparation instructions.
Quality records separate measured results, reference values, acceptance rules, and supporting evidence. Arithmetic consistency and record coverage can be checked against supplied criteria without establishing traceability, approving a method, or deciding product conformity.
Compare supplied mass-basis reference-standard potency fractions without assigning assay purity or preparation instructions.
When to use this tool
Use it for reference standard potency factor when the required inputs and conventions are already available.
How to use the tool and how it works
- Enter weighedMass, suppliedPotencyFraction, referencePotencyFraction. Use the stated units and boundary conventions.
- Run the calculation. Correct any input error before interpreting a result.
- Read activeEquivalent, referenceEquivalentMass. Inspect any known, defined, inclusion, or boundary flags before interpreting numeric values.
Require nonnegative weighedMass, suppliedPotencyFraction from zero through one, and referencePotencyFraction greater than zero and no greater than one. Calculate activeEquivalent=weighedMass*suppliedPotencyFraction and referenceEquivalentMass=activeEquivalent/referencePotencyFraction.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| weighedMass | Weighed Mass | Required. Finite number; minimum 0. |
| suppliedPotencyFraction | Supplied Potency Fraction | Required. Finite number; minimum 0; maximum 1. |
| referencePotencyFraction | Reference Potency Fraction | Required. Finite number; maximum 1; strictly above 0. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| activeEquivalent | Active Equivalent | Required. Finite number. |
| referenceEquivalentMass | Reference Equivalent Mass | Required. Finite number. |

}Limitations and assumptions
- Potencies are fractions, not percentage numerals, and both must use compatible assay bases. Moisture, purity corrections, and reference certification are not inferred.
- The field tables describe structural bounds; the mechanics also state cross-field requirements. Malformed input shapes, disallowed keys, and invalid domains cause input errors. Results must remain finite and within the declared output contract. A successful false flag or zero placeholder is distinct from an error.
- Numeric arithmetic uses binary floating point. Exact comparisons have no hidden tolerance or decimal rounding; negative zero is exported as zero. Decimal-text integer operations retain the exactness specifically stated above.
Alternative or Complementary methods
For reference standard potency factor, check the source records and the supplied rule before comparing the result with another method. Use a separate evidence or method review when arithmetic consistency alone cannot establish the required conclusion.
