TS EN 9125
Aerospace series - Quality management systems - Non-deliverable software requirements
This document specifies the requirements for the effective control of non-deliverable software. This document can be used during the design, development, test, production, release, use, maintenance, and retirement of non-deliverable software. This can include non-deliverable software procured from external suppliers and utilized in the design, production, evaluation, test, acceptance, or calibration of a deliverable product. This document focuses solely on the unique requirements of the operational processes that pertain to non-deliverable software as identified below: This document applies to non-deliverable software (including firmware) that affects a deliverable product or service. Following are several applications and supporting examples of non-deliverable software that is within the scope of this document: — design and development: modelling, simulation, virtual reality, virtual machine, computer-aided design (CAD), three-dimensional (3D) modelling and analysis tools, software compiler, and code generators; — manufacturing: additive manufacturing, computer numerical controlled (CNC) programs, robotics, factory automation, tools that load deliverable software, software used in special process (e.g. heat treat, shot peen, sonic wall inspection), and automated manufacturing software (i.e. pick and place); — verification, validation and maintenance: coordinate measuring machine (CMM) programs, hardware or software qualification, code coverage, test scripts, analysis tools, acceptance test, production acceptance, calibration (inspection, test or calibration), simulator, emulator, and software used in post-delivery service provisions. The following types of software are not within scope of this document: — deliverable software (refer to EN 9115); — manufacturing and measuring equipment embedded software (e.g. operating system, drivers); — enterprise or office software (e.g. MS Office, word processing or spreadsheet applications, Teams, network software, email, employee management system). Operational processes not covered in this document are addressed by the respective organization’s quality management system (QMS), based on the EN 9100-series (i.e. EN 9100, EN 9110, EN 9120) and/or ISO 9001 standards.

About This Item
TS EN 9125 addresses the requirements for effectively controlling non-deliverable software within an aerospace quality management system. The focus is on software that is not handed over as a standalone deliverable, but that still affects the design, production, verification, or calibration of a deliverable product or service.
In practical terms, this type of software often acts as an engineering or manufacturing enabler rather than a customer-facing product. General technical context includes tools such as modelling and simulation software, CAD systems, compilers, code generators, test scripts, CMM programs, and automation software. Even when these tools are not delivered to the end customer, their configuration, version control, verification, and authorized use can materially influence product conformity and traceability.
Typical software uses brought into scope
- Design and development tools such as modelling, simulation, virtual reality, CAD, 3D analysis, compilers, and code generators
- Manufacturing software including CNC programs, robotics, factory automation, special process support, and automated material handling
- Verification, validation, and maintenance tools such as test scripts, analysis tools, simulators, emulators, and CMM programs
- Non-deliverable software procured from external suppliers when it is used to support a deliverable product or service
What the standard leaves outside its scope
The standard excludes deliverable software, embedded software in manufacturing or measuring equipment such as operating systems and drivers, and enterprise or office software such as word processing, spreadsheets, network software, email, or employee management systems. That distinction matters because the document is aimed at operational software processes that can affect a deliverable outcome, while broader organizational processes remain covered by the organization’s QMS based on the EN 9100 series and/or ISO 9001.
Conceptually, the standard is about governance of software used in the product lifecycle: design, development, test, production, release, use, maintenance, and retirement. For aerospace organizations, this helps align software-dependent activities with controlled engineering practice, so that the tools influencing product quality are managed with the same discipline expected of other critical process inputs.
