NIST/ECRC

ISO TC184/SC4 SC4 is an acronym for Subcommittee 4

Focus: Industrial Data Standards Established in 1983 Three areas of work:

1) Digital Product Data Representation ISO 10303 - Industrial Automation Systems and

Integration - Product Data Representation and Exchange. (Unofficially: STEP)

2) Parts Library Representation ISO 13584 - Industrial Automation Systems and

Integration - Standard for the representation of standard parts (Unofficially: PLIB)

3) Manufacturing Management Data (Unofficially: MANDATE)

NIST/ECRC

NIST’s Role in STEP Development

NIST is the SC4 Secretariat Sponsors US industry SC4 Chair Provides the STEP On-line Information

Services (SOLIS), a service which makes all STEP and SC4 information/documentation available electronically

Provides administrative support to US TAG, the formal US representative to SC4

Supports and coordinates industrial input and activity across multiple industrial sectors

NIST/ECRC

IGES/PDES Organization (IPO) US focal point for Product Data Standards and

Technologies; ANSI-accredited consensus standard organization Membership domestic, participation international.

The US technical development body to STEP Established in 1979, conducts quarterly meetings

and maintains IGES Projects are organized similarly to SC4 Principal management provided by NIST;

administrative support provided by USPRO

NIST/ECRC

US Technical Advisory Group

US Body responsible (to ANSI) for establishing US Position on SC4 Ballots

US TAG Chair serves as US Head of Delegation to SC4 Meetings

Voluntary body; small, official membership (~20 organizations); has membership requirements

Solicits & organizes US ballot comments; ballot coordinator responsible for organizing comments
