ISO standards

ISO Standards for Technical Product Specification

BS 308-1:1993, BS 308-2: 1985, and BS308-3:1990 were withdrawn in 2000, and replaced with BS 8888 as the British Standard covering engineering drawing and technical product documentation.

This marks the end of an independent British Standard to cover engineering drawing and documentation, and the adoption in full of ISO standards which are used throughout Europe. As such, BS 8888 does not itself document the principles, practices and procedures to be used in engineering documentation, but instead provides references to the relevant ISO standards that now apply.

Since BS 308 was superceded by BS 8888, and the ISO standards for technical drawing were adopted in full, the number of standards covering technical drawing has expanded to around 200 ISO and EN ISO implementations.

The main standards concerned with geometrical tolerancing are the following:-

BS EN ISO 1101:2017

Geometrical Product Specifications (GPS) – Geometrical Tolerancing – Form, orientation, location and run-out.
(this now incorporates the former ISO 10578 on projected tolerance zones).

BS EN ISO 1660:2017

Geometrical Product Specifications (GPS) – Geometrical Tolerancing – Profile tolerancing.

BS EN ISO 2692:2014

Geometrical Product Specification (GPS) – Geometrical tolerancing – Maximum material requirement and least material requirement.

BS EN ISO 5458:2018

Geometrical Product Specification (GPS) – Geometrical tolerancing – Pattern and combined geometrical specification.

BS EN ISO 5459:2011

Geometrical Product Specification (GPS) – Geometrical tolerancing – Datums and datum systems.

BS EN ISO 8015:2011

Geometrical Product Specification (GPS) – Fundamentals – Concepts, principles and rules.

BS EN ISO 10579:20103

Geometrical Product Specification (GPS) – Dimensioning and tolerancing – Non-rigid parts.

BS EN ISO 14405-1:2016

Geometrical Product Specification (GPS) – Dimensional tolerancing. Part 1: Linear sizes.
