Mold Risk RH Threshold Alert Level Classifier
Actual RH excursion screen under independently applicable collection policy. Duration, temperature, substrate, history and spores unmodeled; no universal mould prediction or safe below-threshold certification.
Description
Relative humidity is one factor in mold-related collection review.
Relative humidity is one factor in mold-related collection review.1
A caller-selected threshold does not independently predict mold growth or establish a safe environment. Use this tool to calculate the stated observation or conditional model from supplied measurements.
When to use Mold Risk RH Threshold Alert Level Classifier
Use this tool to calculate the stated observation or conditional model from supplied measurements. Establish the institution, collection/material context, applicable standards or authority, reference date and measurement units.
How to use Mold Risk RH Threshold Alert Level Classifier and understand its results
- Establish the institution, collection/material context, applicable standards or authority, reference date and measurement units.
- Enter independentlyObservedRhPercent, callerApplicableRhReviewThresholdPercent, using the field meanings and rules below, then run the tool.
- Read result.exceedsCallerRhReviewThreshold, result.signedRhReviewMarginPercentagePoints. Interpret each field using the units, signs and evidence rules below.
- If input validation fails, correct the reported field and run again. Before applying a successful result, check the stated reference scope, units, assumptions and any retained unknown evidence.
| Input field | Meaning | Value type | Requirement |
|---|---|---|---|
| independentlyObservedRhPercent | Independently observed rh percent | number | Required |
| callerApplicableRhReviewThresholdPercent | Caller applicable rh review threshold percent | number | Required |
Require observed and caller review relative-humidity percentages in inclusive 0–100. Flag observed>threshold strictly and return threshold−observed in percentage points. Equality is not an exceedance; no default mold threshold or environmental diagnosis is supplied.
exceeds=(observedRhPercent>callerThresholdPercent); signedMarginPoints=threshold−observed Apply the field units and exact ordering, boundary and evidence rules above.
| Output field | Meaning | Value type |
|---|---|---|
| result | Structured result containing the calculation or selected reference fields below | object |
| result.exceedsCallerRhReviewThreshold | Exceeds Caller Rh Review Threshold; use the units, sign convention and calculation stated above | boolean |
| result.signedRhReviewMarginPercentagePoints | Signed Rh Review Margin Percentage Points; use the units, sign convention and calculation stated above | number |

}Limitations and assumptions
A caller-selected threshold does not independently predict mold growth or establish a safe environment. Results depend on the independently established measurement basis and the exact model assumptions above.
Every listed input requires an explicit value. Unexpected fields, incorrect value types, nonfinite numbers and sparse numeric arrays fail validation; tool-specific bounds and alignment rules apply as described above. Extremely large inputs or outputs can also be rejected. An input error is distinct from a successful calculation that reports a false comparison or retains unknown evidence.

Use Magnetic Tape Binder Hydrolysis Risk Age Flag Checker where its separate inputs and scope apply: Tape age is one possible trigger for conservation review.
