National foreword

This British Standard has been prepared by Technical Committee TDE/4 and is the English language version of EN ISO 5455:1994Technical drawings — Scales, published by the European Committee for Standardization (CEN). It is identical with ISO 5455:1979, published by the International Organization for Standardization (ISO).

This British Standard partially supersedes BS 308‑1. It is envisaged that when the full range of European Standards on technical drawing is implemented BS 308 will be withdrawn.

A British Standard does not purport to include all the necessary provisions of a contract. Users of British Standards are responsible for their correct application.

Compliance with a British Standard does not of itself confer immunity from legal obligations.
