Today's reality

Material data exchange across the value chain remains manual, fragmented and error‑prone.

01

Manual process

  • Test planning and documentation
  • Result consolidation and reporting
  • Repeated data entry across system
02

High coordination effort

  • Manufacturers
  • Suppliers
  • Laboratories
03

Quality and Compliance risks

  • Ambiguous interpretations
  • Transcription and formatting errors
  • Costly corrections and rework

The result: fragmented data, limited comparability and increasing regulatory and compliance risk.

The standardized answer

VDA 231-300 and VDA 231-301 - A standardized, machine‑readable foundation for interoperable material data.

01

Consistent material definition

Standardized material and surface semantics (VDA 231-300) · Clear reference to 3D product data - JT / ISO 14306 · Unambiguous basis for downstream test and compliance data

02

Interoperable test & measurement data

Machine-readable test and measurement results (VDA 231-301) · Standardized structure with formal validation rules · Direct system-to-system exchange without re-typing

ManufacturersSuppliersLaboratories

03

Shared semantic understanding

Common interpretation of material and test data · Reduced coordination effort across companies · Reliable data exchange

VDA 231‑300 Defines what is tested and how materials are described. VDA 231‑301 Defines how results are structured and exchanged – enabling seamless data flow without re-typing or interpretation gaps.

Modular by design

What is VDA 231-301?

VDA 231‑301 enables interoperable, machine‑readable exchange of material and test data across systems, companies and digital ecosystems.

01

Open by default

JSON Schema, no license fees, no proprietary formats — built for any ecosystem.

02

Composable

Combine the generic core with domain-specific subschemas to match your exact use case.

03

Validation built in

Every payload can be checked against the schema in-browser or in your pipeline.

Who benefits

A standard that pays back at every node of the value chain.

Manufacturer

Manufacturer

Define what material data you need — once, in a form every supplier can deliver.

Reduced coordination overhead
Comparable, auditable data
Faster compliance sign-off

Supplier

Supplier

Submit material and test data once and reuse it across all customers.

One format, many customers
Less manual re-entry
Machine-validated results

Test Laboratory

Test Laboratory

Deliver structured, validated test results that integrate directly into customer systems.

Structured report output
Direct system integration
Zero transcription errors

Compliance & Quality

Compliance & Quality

Rely on consistent, formally validated data for audits and sustainability reporting.

Traceable data provenance
Audit-ready records
Regulatory confidence
