DIN audit fix (2026-06-09): hto-edit.owl's existing rdfs:comment/skos:definition treats Aufkohlen as a 'surface hardening process'; DIN EN ISO 4885 §3.36 defines it as 'thermochemische Behandlung zum Anreichern der Oberfläche eines austenitisierten Werkstückes mit Kohlenstoff'. Hardening only follows IF quenching is subsequently applied (cf. §3.37 Einsatzhärten = Aufkohlen + Härten). Original rdfs:label preserved; the §3.36 verbatim definition is added via skos:definition as the canonical anchor.

redaktionelle Anmerkung
-
In practice, the English terms 'equalization' and 'soaking' are synonymous. The standard DIN EN ISO 4885 is ambiguous about the distinction between 'Halten' (§3.185) and 'Durchwärmen' (3.80), and also translates 'soaking' as 'Halten'. The diagram for '§3.80 Durchwärmen' shows the two processes in sequence, whereas the annotation for 'Halten' states that the discrete location within an object must be specified. However, I deem this unnecessary, since 'Halten'/'holding' refers to the process that follows the soaking step and ensures a homogeneous temperature distribution regardless of the location. (thnlrd)

DIN audit (2026-06-09, γ refinement): HTO_0000072 (recently added upstream as case-hardening PROCESS) is overlaid here with DE label 'Einsatzhärten' and verbatim 4885 §3.37 wording. Earlier draft had a twin class hto:HTO_0000106; removed in favour of this overlay to keep upstream IRIs intact (Q2c style). HTO_0000106 slot vacated for Divya to re-claim. The depth measure CHD is the separate HTO_0000089 — do not conflate process with depth.

DIN audit fix (2026-06-09): DIN EN ISO 4885 §3.143 lemma is 'Nitrieren'; DIN 17022-4, DIN 17022-5, and DIN EN ISO 683-5 all use 'Nitrieren' exclusively. The hto-edit.owl DE label 'Nitridieren' is a non-DIN morphological variant. The canonical 'Nitrieren' is hoisted to skos:prefLabel; the legacy 'Nitridieren' is demoted to skos:hiddenLabel.

DIN audit (2026-06-09): DIN EN ISO 4885 has no §3 entry for partial pressure; this is upstream physical-chemistry vocabulary, not DIN-terminology-native. Operational usage in DIN 17022-4 §7.3 (p_NH3, p_H2 in K_N formula) is the only DIN anchor.

DIN audit (2026-06-09): DIN EN ISO 4885 does not enumerate 'Sollwert' as a §3 lemma; PMDco owns the generic 'setpoint' concept upstream. The DIN procedural anchor is DIN 17022-1 §5 (Sollwert / Solltemperatur operational usage). Provenance is therefore procedural rather than terminological.

redaktionelle Anmerkung
-
DIN audit addition (2026-06-09): Glühen-family subclass from DIN EN ISO 4885 §3.89 (Full annealing — listed inline in §3.8 Anm.1 as a named Glühen child). Definition is paraphrased per 4885 conventions; the §3.89 verbatim entry uses generic 'Wärmebehandlung'.
-
deviating from the standard here because 'full annealing' ist supposed to fully transform the microstructure into austenite (hence the name) whereas comparable annealing procedures do not fully transform the material even though they are within the same T-range (normalizing, intercritical annealing). Additional info and explanation provided by TWaldenmaier. (thnlrd)
