Overview
IEC 61671-4:2016 (equivalent to IEEE Std 1671.4‑2014) defines an exchange format, based on Extensible Markup Language (XML), for describing a test configuration used by an Automatic Test System (ATS) to test and diagnose a Unit Under Test (UUT). The standard specifies the TestConfiguration XML schema (TestConfiguration.xsd) and related instance schema, providing a machine-readable way to identify the hardware, software, and documentation required by automatic test equipment (ATE) and test programs.
Key topics and technical requirements
- TestConfiguration XML schema: Formal definition of the structure for representing test station and UUT test assets.
- Instance document rules: How to create valid ATML TestConfiguration instance files that conform to the schema.
- Schema names and locations: Prescribed locations and naming for ATML TestConfiguration schemas to support interoperability.
- Extensibility of ATML XML schemas: Guidance for extending the schema while maintaining compatibility.
- Conformance: Requirements and clauses that define how implementations demonstrate compliance with the standard.
- Supporting material and mappings: Informative annexes (examples, MTPSI card field mappings, bibliography) to assist implementation.
- Terminology and references: Definitions, acronyms and normative references to other ATML framework components.
Practical applications
- Enables consistent exchange of test configuration data between ATE vendors, test program developers, and maintenance systems.
- Supports automated station configuration (station configuration file, Master Configuration Control Document - MCCD) and Master Test Program Set Index (MTPSI) integration.
- Useful in manufacturing test, field maintenance, diagnostics, avionics, defense, and any domain using ATS/ATE for functional or fault‑isolation testing.
- Facilitates automation, repeatability, and integration of test assets across toolchains (test program generation, configuration management, and diagnostic systems).
Who should use this standard
- Test engineers and test program developers creating or consuming ATML TestConfiguration files.
- ATE/ATS manufacturers and system integrators implementing interoperable station configuration and test-data exchange.
- Maintenance organizations and logistics teams requiring standardized test-definition exchange.
- Tool vendors (test management, diagnostic, configuration control) aiming for ATML interoperability.
Related standards
- Other ATML component standards in the IEEE 1671 family (ATML framework) and applicable IEC/IEEE publications addressing instrument description, test results, and test program structures.
