Full title and description

Industrial automation systems and integration — Product data representation and exchange — Part 1680: Application module: Functional unit requirement allocation. This Technical Specification defines the STEP application module for allocating human- and application‑interpretable requirements (customer, regulatory, enterprise) to functional units in a networked functional decomposition.

Abstract

ISO/TS 10303-1680:2006 specifies an application module that supports representation of requirement allocation to functional elements. It covers both human‑interpretable and application‑interpretable requirement assignments, and includes representation of a nodal formulation of a network definition to show how requirements are allocated across functional units.

Scope

The specification defines the data constructs and application module content necessary to represent assignment of requirements to a functional unit within a functional/network decomposition. In scope are: human‑interpretable requirement allocation to a functional unit; application‑interpretable requirement allocation to a functional unit; and representation of a nodal (network) formulation showing how requirements are distributed across functional elements. The module is intended for use within the ISO 10303 (STEP) framework as an application module that can be referenced by higher‑level application protocols or implementations.

Key topics and requirements

• Representation of requirement allocation to functional units (both human- and application-interpretable).
• Definition of data structures to map requirements (customer, regulatory, enterprise) onto functional elements in a networked model.
• Support for nodal/network formulation of functional decompositions to express distributed requirement assignments.
• Interoperability within the STEP architecture — designed to be reused or referenced by APs and implementation methods that exchange product and systems information.

Typical use and users

Implementers and users include systems engineers, PLM/PDM and CAD integration teams, software vendors developing STEP‑compliant import/export or data‑mapping tools, and organizations needing traceable allocation of requirements to functional elements across the product lifecycle. The module is used where formal, machine‑interpretable requirement assignments must be shared between engineering, compliance and downstream systems.

Related standards

ISO/TS 10303-1680 is part of the ISO 10303 (STEP) family of standards for product data representation and exchange. It is intended to be used alongside other STEP application modules and APs that deal with functional modelling, product structure, and lifecycle data. Related parts include core STEP Integrated Resources, relevant APs for systems and functional descriptions, and neighbouring application modules in the 1600–1700 series.

FAQ

Q: What is this standard?

A: ISO/TS 10303-1680:2006 is a STEP application module (Technical Specification) that defines how to represent and exchange requirement allocations to functional units within the ISO 10303 data framework.

Q: What does it cover?

A: It covers the data definitions and constructs needed to assign human‑interpretable and application‑interpretable requirements (customer, regulatory, enterprise) to functional elements, and to represent those assignments within a nodal/network formulation of functional decomposition.

Q: Who typically uses it?

A: Systems engineers, PLM/PLM integration teams, CAD/PLM software vendors, and organizations requiring formal, interoperable representation of requirement-to-function allocations across design and lifecycle systems. Implementers of STEP/AP‑based exchanges also use the module.

Q: Is it current or superseded?

A: The 2006 Technical Specification (Edition 1) remains published; ISO records show it was reviewed and confirmed in the ISO 5‑year review process (confirmed in 2023), so this edition is current unless a later revision or replacement has been published after that confirmation. Users should check the ISO catalogue for any post‑2023 revisions.

Q: Is it part of a series?

A: Yes — it is one application module within the ISO 10303 (STEP) family of standards for product data representation and exchange; application modules like this are used by APs and implementers across industries.

Q: What are the key keywords?

A: Functional unit, requirement allocation, STEP, ISO 10303, application module, PLM, data exchange.
