Data rules
We do not turn marketplace titles into engineering facts. Source material is normalized, reviewed and labeled before publication.
Corrections
Send corrections to [email protected] with the page URL, disputed value and supporting source. Material changes are logged with a new reviewed date.
Content depth and review
Technical pages should answer the selection question, explain the calculation or decision path, give a worked interpretation, identify common mistakes and list usable RFQ fields. Images need descriptive alternative text and must support the subject rather than act as decoration.
Corrections and commercial independence
Corrections are assessed against primary standards, published technical references and reproducible calculations. A future sourcing introduction does not change a calculator result or remove access to the independent guidance.
