Geometrical Product Specification
View enquiry form- GPS Foundation Course
- Executive Overview course
What is it?
An intensive four-day course introducing the fundamental principles of Geometrical Product Specification (to BS 8888 and relevant ISO standards).
- Discover how the system of geometrical product specification works.
- Find out how to annotate drawings correctly
- Learn how different types of tolerance control different characteristics, and how to choose the right tolerance for your application.
- Start to benefit from a better standard of specification
This incorporates in full the contents of our most popular course, Geometrical Tolerancing to BS 8888 & ISO Standards – Level 1, with the addition of modules to cover surface texture and edge tolerances.
The course uses examples of your own drawings or products, where available, to illustrate some elements of the course material, and as the basis of some worked examples.
Duration
4 days.Who is it for?
Mechanical, production and design engineers, drawing office and inspection personnel.
Some familiarity with engineering drawing practice and conventional dimensioning and tolerancing is required.

What is it?
A half day overview of Geometrical Product Specification (GPS) and the ISO system of standards that it is based on.
- Learn how ISO GPS can improve communications.
- Find out how ISO GPS can raise levels of quality.
- Discover how ISO GPS can improve productivity and reduce costs.
This course explains how GPS is defined in collection of interlinked ISO standards, and provides an overview of the different elements of the system, including geometrical tolerancing and surface texture specifications.
The Executive Overview is appropriate for managers, supervisors, and decision makers, who need a broad-brushstrokes understanding of the GPS methodology and its implementation.
Duration
3½ hours.Who is it for?
Managers, supervisors and decision-makers in manufacturing industry.
This course can also be used as an introduction for designers, engineers and technical staff who will go on to take more detailed practitioner’s courses.
