How BHT-X content is written
- technical principles are checked against official standards catalogue pages and reputable public method references;
- content is rewritten in original language rather than copied;
- general guidance is separated from controlled acceptance requirements;
- product claims are limited to public Multitek information or clearly marked as configuration-dependent;
- articles show a review/update date and are corrected when evidence changes;
- commercial links do not change the technical formula or suppress limitations.

Common Brinell terms
| Term | Meaning in this site |
|---|---|
| HBW | Brinell hardness determined with a tungsten carbide ball. |
| D | Ball diameter in the hardness formula. |
| d, d₁, d₂ | Mean indentation diameter and its two approximately perpendicular readings. |
| Test force F | Force applied by the verified machine under the selected scale. |
| Dwell time | Time the specified force is maintained as defined by the method. |
| Direct verification | Evaluation of defined machine components/functions under the applicable verification standard. |
| Indirect verification | Evaluation of system performance using standardized reference blocks. |
| BHN | Common informal phrase “Brinell hardness number”; formal reporting commonly uses HBW designations. |
