Documents and technical conditions

Last updated 2026-10-06 · document list revision 6

The shop works to its own technical conditions and methods; we reference outside standards in words, by the method agreed with the customer, rather than by number.

Technical conditions

• ТУ-ВН 02 Acceptance of parts by hardness and geometryrev. 4 · 2026-10-06
• ТУ-ВН 05 Conditions on the carburised case and its depthrev. 3 · 2026-09-28
• РД-01 Tempering schedule after quenchingrev. 5 · 2026-10-02

Measurement methods

• МИ-05 Hardness measurement by Rockwell and Brinellrev. 3 · 2026-10-06
• МИ-07 Sampling of measurement points per part and per batchrev. 2 · 2026-09-24
• КИ-11 Control card for the carburised case from a witnessrev. 2 · 2026-09-08

Copies of the current revisions are kept at the shop; an extract for a given order is issued with the protocol. Acceptance is judged against the revision in force on the date the charge was treated.

Acceptance protocol

The protocol form is eight points, from the contract number to the verdict with the heat treater's signature. The point-by-point breakdown lives on the control page, so it is not repeated here.

Machine-readable data

The routes register and the defect base sit as files next to the site and are served as they are; the route picker is built on them.

• /api/regimes.json register of 25 routes with process, grade, temperature and quenchant fieldsupd 2026-10-06
• /data/regimes.csv the same register as a table for downloadCSV
• /api/defects.json the typical-defect base in both languagesupd 2026-09-08

Field names in the files are in Latin; temperatures are in Celsius, hardness in HRC or HB. The bands are working values and are refined per part against the drawing.
