Question
State the decision and required evidence.
Method before claim
Engineering Lab
Test methods become evidence only when the setup, variables and limitations are visible.

Evidence architecture
General methods are published now. HAION results appear only after approval.
This page does not simulate a HAION laboratory or publish unverified performance data. It explains how useful caster and mobility evidence should be structured.
Method
Define setup, variables, units and controls.
Measurement
Record the result with operating conditions.
Boundary
Separate observations from approved claims.
Define the question
State the behavior, operating condition and decision the test must support.
Control the setup
Record equipment, load, wheel, floor, speed, route and environment.
Measure variables
Use visible units, sampling and instrument boundaries.
Report limitations
Separate observations from product claims and application approval.
Rolling resistance is not a single material value.
It is the measured response of the wheel, caster, load, alignment and floor at a defined operating condition.
Wheel geometry
Diameter, tread and deformation influence the contact response.
Load
The complete load path changes wheel and bearing behavior.
Floor
Joints, debris, texture and thresholds can dominate the route.
Alignment
Swivel orientation and wheel layout affect actual push force.
Installed caster load is an equipment problem.
Use a conservative support assumption for preliminary sizing, then validate the real frame and route.
Total mass
Include equipment, payload, accessories and foreseeable loading.
Center of gravity
Check how the load shifts across the installed caster positions.
Frame stiffness
Do not assume every caster carries an equal reaction.
Floor condition
Allow for uneven support, thresholds and dynamic transfer.
