Engineering standards

Match the evidence to the application

Dimensions, test scope and regulatory context should be reviewed together before a wheel is specified.

Specification and validation matrix

Use the following categories to prepare a product-specific review. Exact tolerances and acceptance limits belong on the approved drawing and test plan.

Review area	Information to provide	Evidence to consider
Fitment	Diameter, width, PCD, offset and center bore	Drawing, mating hub and tire interface
Load	Axle load, wheel position and duty cycle	Specified rating and test conditions
Geometry	Datums and tolerance limits	Radial and lateral runout measurement
Environment	Exposure, coating and storage conditions	Agreed inspection and protection requirements
Market	Destination and product classification	Applicable regulation and scope of approval

Evidence checklist

Identify the exact wheel and drawing revision covered by each document.
Confirm test method, specimen and acceptance criteria in the report.
Review whether UNECE, DOT/FMVSS, SAE or JWL/VIA requirements apply to the product and market; their scopes are not interchangeable.
Separate quality management system certificates from product approvals.
Agree how lot identification and inspection records relate to the order.

A certificate or report is meaningful only within its stated scope. Request current evidence and verify the issuing body, validity and product applicability before relying on it for a release decision. Changes to geometry or duty may require a fresh assessment.
