Acid-Free Mount Board pH Pass Checker
Matched board-pHwindow screen only; measurement method and material policy independently verified. pHdoes not certify acid-free/lignin-free/PAT pass, buffering suitability or long-term preservation.
Description
Mount-board pH is one measured property relevant to material compatibility.
Mount-board pH is one measured property relevant to material compatibility.1
A supplied pH interval alone does not establish archival suitability.
When to use Acid-Free Mount Board pH Pass Checker
Use this tool to calculate or review the supplied observations under the stated rules. Establish the object or visitor scope, measurement units and independently applicable conservation, engineering, access or editorial reference.
How to use Acid-Free Mount Board pH Pass Checker and understand its results
- Establish the object or visitor scope, measurement units and independently applicable conservation, engineering, access or editorial reference.
- Enter independentlyMeasuredBoardPh, callerApplicableMinimumPh, callerApplicableMaximumPh, using the field meanings and rules below, then run the tool.
- Read result.withinCallerPhScreen. Use the units and sign conventions below.
- Correct any reported input issue and run again. Before using a successful result, check the stated units, signs, reference scope and observation coverage.
| Input field | Meaning | Value type | Requirement |
|---|---|---|---|
| independentlyMeasuredBoardPh | Independently measured board ph | number | Required |
| callerApplicableMinimumPh | Caller applicable minimum ph | number | Required |
| callerApplicableMaximumPh | Caller applicable maximum ph | number | Required |
Require measured, minimum and maximum pH all within 0–14 and maximum≥minimum. Return whether the measurement lies inside the inclusive supplied interval; no material-compatibility decision is added.
withinPh=(minimumPh≤measuredPh≤maximumPh) Use the matching field units and the exact boundary, ordering and reference rules above.
| Output field | Meaning | Value type |
|---|---|---|
| result | Structured result; its nested fields below contain the actual calculation or selected reference | object |
| result.withinCallerPhScreen | Within Caller Ph Screen | boolean |
{
"input": {
"independentlyMeasuredBoardPh": 7,
"callerApplicableMinimumPh": 6.5,
"callerApplicableMaximumPh": 8.5
},
"output": {
"result": {
"withinCallerPhScreen": true
}
}
}Limitations and assumptions
Object condition, observation coverage and applicable references determine applicability. A supplied comparison or record does not certify conservation treatment, engineering, access compliance or insurance eligibility.
Missing required fields, unknown fields, wrong types and violated rules return input issues. Numeric values and outputs must be finite. Extremely large composite outputs are rejected.
Alternative or Complementary methods
For a related step, use Temperature Setpoint by Collection Type Lookup: Collection temperature setpoints depend on material condition and the applicable conservation reference. For a complementary comparison, use Relative Humidity Setpoint by Material Class Lookup: Relative-humidity setpoints depend on material, condition and applicable conservation guidance.
