Enclosure Folder Acid-Free pH Pass Checker
Actual folder/enclosure pHscreen under independently verified material policy/test method. pHalone does not prove acid-free, lignin-free, buffering suitability, PAT pass or long-term preservation.
Description
Enclosure pH is a measured material property with a sampling and testing basis.
Enclosure pH is a measured material property with a sampling and testing basis.1
A supplied pH window does not establish complete archival suitability or conservation approval. Use this tool to calculate the stated observation or conditional model from supplied measurements.
When to use Enclosure Folder Acid-Free pH Pass Checker
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 Enclosure Folder Acid-Free pH Pass Checker and understand its results
- Establish the institution, collection/material context, applicable standards or authority, reference date and measurement units.
- Enter independentlyMeasuredEnclosurePh, callerApplicableLowerPh, callerApplicableUpperPh, using the field meanings and rules below, then run the tool.
- Read result.withinCallerEnclosurePhWindow. 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 |
|---|---|---|---|
| independentlyMeasuredEnclosurePh | Independently measured enclosure ph | number | Required |
| callerApplicableLowerPh | Caller applicable lower ph | number | Required |
| callerApplicableUpperPh | Caller applicable upper ph | number | Required |
Require measured and caller pH bounds in inclusive 0–14, with upper≥lower. Compare inclusively and return the boolean only. No testing method, material policy or conservation approval is selected.
withinPhWindow=(callerLowerPh≤measuredPh≤callerUpperPh) 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.withinCallerEnclosurePhWindow | Within Caller Enclosure Ph Window; use the units, sign convention and calculation stated above | boolean |
{
"input": {
"independentlyMeasuredEnclosurePh": 7,
"callerApplicableLowerPh": 6.5,
"callerApplicableUpperPh": 8.5
},
"output": {
"result": {
"withinCallerEnclosurePhWindow": true
}
}
}Limitations and assumptions
A supplied pH window does not establish complete archival suitability or conservation approval. 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.
Alternative or Complementary methods

Use Lignin-Free Box Certification Label Validator where its separate inputs and scope apply: A lignin-free label needs evidence matched to the actual product and lot.
