A compendium of science and standards.
Wertek AI is built on top of mature international standards. This documentation explains how — from asset hierarchy doctrine and equipment taxonomy, to event interoperability and integration frameworks.

"We didn't invent another asset model. We materialized the ones the industry already trusts: ISA-95 for hierarchy, ISO 14224 for taxonomy, Brick for HVAC ontology, KKS for power plants. Wertek is what happens when those standards run as living software." — Wertek AI engineering doctrine
How Wertek represents physical assets, why the model is the way it is, and which international standards back each decision.
Five canonical levels (Organization → Plant → Area → Asset → Sub-Asset) and a single rule to decide what becomes a node and what stays a property: do you measure it alone, replace it alone, or maintain it alone?
Read doctrine →How Wertek's data model maps one-to-one onto ISA-95 / IEC 62264, ISO 14224 (9 levels), Brick Schema 1.4 (HVAC), Project Haystack 4 (tagging), and KKS / RDS-PP / IEC 81346 (power plants).
View alignment →Canonical sub-component list per equipment type (chiller, AHU, pump, gas turbine, transformer, capacitor bank, etc.). The structure your customers receive when they pick a template.
Preview catalog →Pre-built systems: chiller plant N+1, AHU dual-fan economizer, VRV office, compressed air redundant, combined cycle block. Customers don't design — they pick.
Browse templates →Open standards Wertek publishes or implements directly, available for any vendor to adopt.
Open event specification for asset measurement, health, hierarchy, work-order intent, and lifecycle events. Published with formal RFC, Zenodo DOI, Python & TypeScript SDKs, Node-RED nodes.
Read the spec at iaes.dev →Bidirectional connectors for SAP PM, SAP B1, Odoo, MaintainX, Fracttal, IBM Maximo, AVEVA Data Hub, OSI PI System, Banner DXM. Every connector is an IAES bridge — zero custom logic per system.
View integrations →The full ISO 14224 taxonomy implemented in Wertek: 6 equipment classes, 28 groups, 67 equipment types — assigned to assets via the IS_TYPE relationship. Foundation for failure-mode analysis.
View taxonomy →Field-ready guides: vibration, ultrasound, electrical, predictive maintenance — free, open, no registration.
Severity classification (vibration), bearing fault frequencies, ultrasound leak quantification, steam trap evaluation, partial discharge, thermal severity, and predictive maintenance guides.
Browse engineering guides →Country-specific power quality thresholds: power factor, THD, sags, swells, penalties. Mexico (FP 0.97), Brazil (0.92), USA (0.90), Peru (0.96), South Africa (0.96), and 12 more.
View grid codes →Asset management lifecycle, maturity assessment, risk register, NCR tracking, SAMP templates, evidence pack export. How Wertek delivers an ISO 55001-compliant program out of the box.
Read framework →If you're modeling a new vertical, evaluating Wertek for a Tier-1 deployment, or auditing how your data model maps to international standards — we'd be glad to talk.
