getExceedances

getExceedances(sample, limits): Exceedance

Compares a sample's usable results with a limit set (or a list of limits).

• Results resolve through parameterKey, so a CAS-coded result matches the limit of its welldot equivalent.
• Turbidity: turbidity, turbidity_ntu and turbidity_fnu match a limit on any of those codes; turbidity_fau is never compared.
• A limit with fraction applies only to results of that fraction (a result without fraction counts as total).
• presence_allowed: false is exceeded by presence: true (presence).
• < and not_detected never exceed a maximum (< is below a minimum when its value is ≤ min); > exceeds a maximum when its value is ≥ max. Other numeric values are compared directly (bounds inclusive).
• Rejected results and text results are skipped.
