AG12 - Mathematical support group (Advisory Group 12) 

Convenor Paul Scott, UK

ISO/TC 213's mathematical support group is working on a new series of standards relating to "partitioning" - the operation used to identify a portion of a geometrical feature belonging to the real surface of the workpiece or to a surface model of the workpiece. 

The three part ISO 18183 series is currently approaching its final voting stage (FDIS): 

• ISO/FDIS 18183-1, Partitioning -- Part 1: Basic concepts
• ISO/FDIS 18183-2, Partitioning -- Part 2: Nominal model
• ISO/FDIS 18183-3, Partitioning -- Part 3: Methods used for specification and verification

 

AG13 - Identification of user needs (Advisory Group 13)

Convenor Johan Dovmark, Denmark

AG13 is currently focussing on a number of terminology issues as well as discussions around measurement reports, user need gap analysis (design process diagram, characteristics matrix), GPS&V Graphical Language, and any other new user needs. 

 

WG2 - Datums and datum systems (Working Group 2) 

Convenor Renald Vincent, France

WG2's main focus of work is the key ISO GPS standard ISO 5459:

• ISO 5459:2011, Geometrical product specifications (GPS) -- Geometrical tolerancing -- Datums and datum systems. 

The datums group is currently working with its experts to establish the best way forward for the next revision of ISO 5459. 

 

WG4 - Uncertainty of measurement and decision rules (Working Group 4) 

Convenor Alessandro Balsamo, Italy

WG4 is currently looking into revising Part 2 of its ISO 14253 series: 

• ISO 14253-2 Inspection by measurement of workpieces and measuring equipment -- Part 2: Guidance for the estimation of uncertainty in GPS measurement, in calibration of measuring equipment and in product verification

Proposals for its revision will be discussed at the next meeting. 

 

WG6 - General requirements for geometrical product specification (GPS) measuring equipment (Working Group 6) 

Convenor Jim Salsbury, USA

WG6, which looks after the standards for measuring equipment, is currently working on a number of revisions to its existing standards. 

• ISO 1938-1 (limit gauges and gauging limits of size)

• ISO 463 (mechanical dial gauges)

In addition, the group is continuing to deal with the work on rotary axis form measuring instruments as well as new work on ISO 5059-1 (two-point inside micrometers).

A number of other potential revision projects will also be discussed at the next WG6 meeting.  

 

WG9 - Dimensional and geometrical tolerancing for castings (Working Group 9)

Outgoing Convenor Georg Henzold, Germany; Incoming Convenor Thorsten Engelke, Germany

The castings working group looks after the ISO 8062 series.

Further potential work on Part 4 and Part 3 of the series will be discussed at the next meeting. 

• ISO 8062-4, Dimensional and geometrical tolerances for moulded parts -- Part 4: General tolerances for castings using profile tolerancing in a general datum system

• ISO 8062-3, Dimensional and geometrical tolerances for moulded parts -- Part 3: General dimensional and geometrical tolerances and machining allowances for castings 

 

WG10 - Coordinate measuring machines (Working Group 10) 

Convenor Craig Shakarji, USA

WG10 looks after the ISO 10360 series and the ISO 15530 series covering coordinate measurement systems.

The group is working on a number of projects to revise existing parts of the ISO 10360 series as well as creating new parts of the series to address computed tomography (CT). 

 

 

WG12 - Size  (Working Group 12)

Convenor Hans Lilja, Sweden 

WG12 looks after a number of standards relating to size such as the ISO 286 series for linear sizes and the ISO 14405 series on dimensional tolerancing (linear sizes, sizes other than linear sizes, and angular sizes). 

The working group is currently dealing with the revision of ISO 14405-1. 

 

WG14 - Vertical GPS principles (Working Group 14) 

Convenor Renald Vincent, France 

WG14 looks after the ISO 17450 series on general and basic concepts as well as key ISO/TC 213 standards such as ISO 8015. Discussions are currently under way within the working group as to the next revision of ISO 8015:

ISO 8015:2011, Geometrical product specifications (GPS) -- Fundamentals -- Concepts, principles and rules.

 

 

WG15 - GPS extraction and filtration techniques (Working Group 15)

Convenor Paul Scott, UK 

WG15 is responsible for the ISO 16610 series on filtration.

16 parts of the series have already been published with further parts under discussion and/or already under development. 

Current project work within the working group includes the following: 

ISO/TR 16610-32,  Filtration -- Part 32: Robust profile filters: Spline filters

ISO 16610-45, Filtration -- Part 45: Morphological profile filters: Segmentation

 

WG16 - Areal and profile surface texture (Working Group 16) 

Convenor John Westberg, Sweden 

WG16 is responsible for the large series of standards on surface texture; areal the ISO 25178 series. 14 parts of the series have already been published. 

The working group is discussing and developing additional new parts of that series as well as brand new work on the ISO 21920 series on surface texture: profile.

Recently published documents include the following: 

• ISO 12179, Surface texture: Profile method -- Calibration of contact (stylus) instruments

• ISO 21920-1, Surface texture: Profile -- Part 1: Indication of surface texture

• ISO 21920-2, Surface texture: Profile -- Part 2: Terms, definitions and surface texture parameters
