NIOSH Asymmetry Multiplier Lookup
RNLE actual asymmetry-plane angle multiplier1−.0032A, not measured trunk torque. Caller independently establishes matching units, evidence, method edition and applicability; output is not compliance, diagnosis, work-safety approval, geological identity or validated hazard prediction.
Description
The NIOSH asymmetry multiplier adjusts for a supplied angular displacement from the lifting reference plane.
The NIOSH asymmetry multiplier adjusts for a supplied angular displacement from the lifting reference plane.1
That angle is an observation input rather than something inferred from body images or load coordinates. Use this tool to calculate NIOSH Asymmetry Multiplier Lookup from the supplied measurements and assumptions.
When to use NIOSH Asymmetry Multiplier Lookup
Use this tool to calculate NIOSH Asymmetry Multiplier Lookup from the supplied measurements and assumptions. Establish the observation protocol, units, task and reference population or review criterion before entering measurements.
How to use NIOSH Asymmetry Multiplier Lookup and understand its results
- Establish the observation protocol, units, task and reference population or review criterion before entering measurements.
- Enter asymmetryDegrees, using the field meanings and rules below, then run the tool.
- Read asymmetryMultiplier. Interpret the fields using their units, signs and evidence conventions below.
- If input validation fails, correct the reported field and run again. Before applying the result, check reference scope, model assumptions and any missing evidence or placeholder values.
| Input field | Meaning | Value type | Requirement |
|---|---|---|---|
| asymmetryDegrees | Asymmetry degrees | number | Required |
Enter asymmetry angle in degrees from zero through 135. Return 1−0.0032×angle. The supplied angle is not measured or inferred, and other lifting multipliers are not calculated.
AM=1−0.0032×angleDeg Use the exact units, boundary rules, ordering and missing-evidence conventions above.
| Output field | Meaning | Value type |
|---|---|---|
| asymmetryMultiplier | Asymmetry Multiplier; follow the units, sign, ordering and evidence convention stated above | number |

}Limitations and assumptions
That angle is an observation input rather than something inferred from body images or load coordinates. Interpretation depends on the units, sampling scope and exact model described above.
All listed fields require explicit values. Unexpected fields, incorrect types, nonfinite numbers and sparse evidence arrays fail validation; the specific bounds and alignment requirements are stated above. Extremely large inputs or outputs can also be rejected. An input error is distinct from a successful result reporting false, no matches or missing evidence.
Alternative or Complementary methods
Use NIOSH Vertical Multiplier Lookup for this related task: The NIOSH vertical multiplier adjusts a lifting model for hand height relative to its reference height.
Use NIOSH Horizontal Multiplier Lookup when its separate inputs and assumptions fit the question: The NIOSH horizontal multiplier reduces a lifting-model allowance as horizontal reach increases.
