Introduction to BS 8888

View enquiry form

BS 8888 is the current British Standard for Technical Product Specification and Documentation. It replaced BS 308 in 2000. Further information about BS 8888 can be found here

  • An Introduction to BS 8888
  • Executive Overview course
  • BS 308 to BS 8888 conversion course

What is it?

This course provides a one-day overview of the requirements of BS 8888.  The course includes a review of good practice for technical product specification, as well as covering the key concepts and requirements of BS 8888:

  • Format and presentation requirements.
  • Working with 2D and 3D data.
  • The principles of product definition

Topics such as geometrical tolerancing and surface texture requirements are covered in very general terms – specific courses are available for those who need a more detailed understanding of these topics.

Duration

One day

Who is it for?

  • Anyone who needs to understand the principles and practices of developing engineering drawings to a professional standard, and in compliance with BS 8888.

What does it cover?

  • Standards in context
    • BS 8888 and the ISO system
  • Technical Product Specification
    • Principles
    • Use of 2D and 3D data
    • Letters and numbers (covering metric and imperial requirements)
    • Dimensions
  • Tolerances
    • Linear tolerances (including limits and fits)
    • Geometrical tolerances
    • General tolerances (including BS EN 22768)
    • Surface texture
    • Edge tolerance
  • Geometrical Product Specification
    • the four fundamental geometrical properties
    • the Seven Step system
  • Features and features of size
  • Size tolerances, the Envelope Requirement and ISO 14405-1
  • Markings on drawings
  • Compliance and implementation

What is it?

A ½ day overview of BS 8888 and the ISO standards that it is linked to.

Discover the benefits of the ISO system of Geometrical Product Specification, its potential to reduce costs and to improve quality.

BS 8888 implements the ISO system for Technical Product Specification, which covers the definition of work piece geometry, surface and edge requirements, and its presentation in 2D or 3D format.

The Executive Overview is appropriate for managers, supervisors, and decision makers, who need a broad-brushstrokes understanding of the requirements of the standard and its implementation.

Find out what you need to do to comply with the standards.

BS 8888 is referenced by Def Stan 05-10, so defence projects are required to conform to BS 8888.

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.

What does it cover?

  • BS 8888 and the ISO system
  • Geometrical Product Specification (GPS)
  • ISO GPS in practice
    • features and sizes
    • the seven step system
    • datums and datum systems
    • geometrical tolerancing
    • surface texture specification
    • surface imperfections
    • edge tolerances
  • 2D and 3D documentation
  • how to implement BS 8888
  • how to benefit from BS 8888
  • future developments

What is it?

A half day course for engineers, designers and technicians who need to up-date from BS 308 practices to BS 8888 and the ISO system.

This course provides an overview of what has changed with the new standard (and what has not changed).

Topics such as geometrical tolerancing and surface texture requirements are covered in very general terms – specific courses are available for those who need a more detailed understanding.

  • Learn why BS 308 had to be replaced by BS 8888.
  • Find out about the ISO system of Geometrical Product Specification.
  • Discover what you need to do to comply with BS 8888.

Please note: this is not an appropriate course for those who need to be trained up on the correct use and interpretation of Geometrical Tolerancing. That is covered in the Geometrical Tolerancing to BS 8888 & ISO standards course.

Duration

3½ hours

Who is it for?

  • BS 308 and BS 8888
  • the ISO system
  • what has changed from BS 308
  • requirements for 2D drawings
