Ladder Rung Spacing Compliance Checker
Actual actual ladder rung spacing versus applicable manufacturer/standard bounds; no ladder compliance certification versus independently applicable ordered caller review bounds in caller independently declared matching unit. Endpoints inclusive, all margins signed. No default benchmark, universal threshold, compliance, medical reassurance or safe operation approval; authoritative protocol/context and measurement uncertainty external.
Description
Ladder rung spacing is a measured configuration value tied to an applicable specification.
Ladder rung spacing is a measured configuration value tied to an applicable specification.1
A numerical band check depends on that independently established reference.
When to use Ladder Rung Spacing Compliance Checker
Use this tool to compare a measurement with the supplied applicable bounds. Establish the survey or observation scope, reference frame, units and independently applicable calibration or qualified plan.
How to use Ladder Rung Spacing Compliance Checker and understand its results
- Establish the survey or observation scope, reference frame, units and independently applicable calibration or qualified plan.
- Enter independentlyMeasuredValue, callerApplicableLowerReviewValue, callerApplicableUpperReviewValue, using the field meanings and rules below, then run the tool.
- Read withinCallerReviewBounds. Inspect signedLowerMargin and signedUpperMargin: a negative margin identifies the exceeded boundary; both endpoints are included.
- 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 |
|---|---|---|---|
| independentlyMeasuredValue | Independently measured value | number | Required |
| callerApplicableLowerReviewValue | Caller applicable lower review value | number | Required |
| callerApplicableUpperReviewValue | Caller applicable upper review value | number | Required |
Enter a finite observation and independently applicable lower and upper bounds in the same units. Require lower≤upper, including equal bounds. Both endpoints pass the inclusive comparison. Return the within-bounds boolean and two signed margins; a negative margin identifies which boundary is exceeded. The implementation does not impose additional physiological ranges or choose the bounds.
within=(lower≤observed≤upper); lowerMargin=observed−lower; upperMargin=upper−observed Use the matching field units and the exact boundary, ordering and reference rules above.
| Output field | Meaning | Value type |
|---|---|---|
| result | Qualified observed calculation or explicit reference | object |
| result.withinCallerReviewBounds | True when the measurement is between the supplied bounds, endpoints included. | boolean |
| result.signedLowerMargin | Observed value minus the supplied lower bound. | number |
| result.signedUpperMargin | Supplied upper bound minus observed value. | number |

}Limitations and assumptions
The actual observation coverage, calibration and qualified plan determine applicability. A numerical result does not establish survey accuracy, route suitability, atmosphere conditions or equipment adequacy beyond the declared comparison. Passing means only that the supplied measurement is inside the supplied inclusive bounds.
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.
