ISO 10303-49-1998 PDF

Full title and description

Industrial automation systems and integration — Product data representation and exchange — Part 49: Integrated generic resources: Process structure and properties (ISO 10303-49:1998). This part of the ISO 10303 (STEP) family defines integrated resource constructs for specifying process definitions, relationships between processes, process effectivity and properties, resources required by processes and their properties, and the relationship of processes to product definitions; the constructs can be assembled (with application resources or protocols) into process plans and process-step representations.

Abstract

ISO 10303-49:1998 specifies EXPRESS-based resource constructs that represent actions (or potential actions) to effect manufacturing or other processes. It covers process specification, relationships and sequencing of processes, effectivity, alternative process definitions and realization methods, identification and properties of resources used by processes, and mapping between processes and products to support process planning and related data exchange. Administrative metadata (such as organization or author) is out of scope.

Scope

This part of ISO 10303 defines the integrated generic resource constructs needed to describe processes and process-related information for product realization and manufacturing planning. It includes: (a) constructs for specifying a process and its constituent steps; (b) relationships and sequencing between processes; (c) definition of effectivity and alternative process plans; (d) the identification and properties of resources (machines, tools, materials) used by processes; and (e) representation rules that allow assembly of these constructs into process plans for data exchange between CAx and PLM systems. Administrative metadata and execution-state history are intentionally excluded.

Key topics and requirements

• Resource constructs for process specification (process, process_step, method, operation) enabling explicit representation of process structure and steps.
• Definitions of process effectivity and alternatives to support conditional or variant process plans.
• Resource identification and property constructs for machines, tools, fixtures, materials and other resources required by processes.
• Mapping of process elements to product definitions to support integration with product geometry and product-structure models.
• EXPRESS schema-based definitions (structured data semantics) intended for use with STEP implementation methods (e.g., STEP-file, SDAI).

Typical use and users

Primary users include standards engineers, CAD/CAM/PLM implementers, process planners, manufacturing integration specialists and software vendors who need to model, exchange, or archive process plans and resource requirements as structured data. Typical uses are neutral data exchange of process plans between enterprise systems, long‑term archival of manufacturing process definitions, and as a resource base when building application protocols or application modules that require process modelling.

Related standards

ISO 10303-49 is part of the ISO 10303 (STEP) family. Closely related parts and references include: ISO 10303-1 (overview and fundamental principles), ISO 10303-11 (EXPRESS language reference), implementation-method parts such as ISO 10303-21 (STEP-file), and other Integrated Generic Resource (IR) parts in the 41–62 range that define complementary resource types (for geometry, shape, material, etc.). Application Protocols (APs) such as AP 242 and related APs rely on IR parts for foundation. The part also references other standards used for data description (for example ISO/IEC 8824-1 where applicable).

FAQ

Q: What is this standard?

A: ISO 10303-49:1998 is Part 49 of the ISO 10303 family (STEP) that defines integrated generic resource constructs for representing process structure and process-related properties used in process planning and manufacturing data exchange.

Q: What does it cover?

A: It covers EXPRESS-based constructs to describe processes, process steps, relationships and sequencing, effectivity/alternatives, resources and resource properties, and the mapping between processes and product definitions; administrative information and execution history are out of scope.

Q: Who typically uses it?

A: CAD/CAM/PLM software vendors, integration and standards engineers, process planners and manufacturing IT specialists who need a neutral, implementation‑independent data model for process plans and process/resource information.

Q: Is it current or superseded?

A: The ISO record shows ISO 10303-49:1998 as the published (confirmed) international standard (Edition 1, 1998). Users should verify national adoptions or later revisions for their jurisdiction or application; there is no ISO record of a newer Part 49 edition replacing the 1998 publication at the time of this summary.

Q: Is it part of a series?

A: Yes — it is one part of the STEP (ISO 10303) family. Parts 41–62 are the Integrated Generic Resources group (of which 49 is one), and many other STEP parts (description methods, implementation methods, APs, modules) compose the full standard family.

Q: What are the key keywords?

A: STEP, ISO 10303, process structure, resource constructs, EXPRESS, process plan, manufacturing data exchange, integrated generic resources.
