Technical drawings — General principles of presentation Part 24: Lines on mechanical engineering drawings
National foreword This British Standard is the UK implementation of ISO 128-24:2014. It supersedes BS ISO 128-24:1999 which is withdrawn. The UK participation in its preparation was entrusted to Technical Committee TDW/4, Technical Product Realization. A list of organizations represented on this committee can be obtained on request to its secretary. This publication does not purport to include all the necessary provisions of a contract. Users are responsible for its correct application. © The British Standards Institution 2014.

Foreword ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the different types of ISO documents should be noted. This document was drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 2. www.iso.org/directives

5 Line widths and line groups On mechanical engineering drawings, two line widths are normally used. The proportions between the line widths should be 1:2. The line groups are specified as shown in Table 2.
Table 2 — Line groups Line widths
Line group 0,25
0,35 0,5a 0,7a 1
Preferred line groups
01.2 – 02.2 – 04.2 0,25
0,35 0,5
for line no.
Dimensions in millimetres 01.1 – 02.1 – 04.1 – 05.1 0,13 0,18
The widths and groups of lines should be chosen according to the type, size and scale of the drawing and according to the requirements for microcopying and/or other methods of reproduction.
Examples of application Table A.1 gives examples of the application of the different types of lines indicating the reference number given in Table 1. The figures are shown in first angle projection. It is understood that third angle projection could be used as well. Table A.1 — Examples of application
