NATlONAL FOREWORD

This Indian Standard (Part 25) which is identical with ISO 128-25 : 1999 ‘Technical drawings —General.principles of presentation — Part 25: Lines on shipbuilding drawings’ issued by the InternationalOrganization for Standardization (ISO) was adopted by the Bmeau of Indian Standards on therecommendation of-the Drawings Sectional Committ6:e and approval of the Production and GeneralEngineering Division Council.

ISC 128 was published in 1982 and was accordingly adopted as IS 10714:1983. ISO 128:1982 waswithdrawn and published again in several parts. In view of this Drawings Sectional Committee decidedto adopt ISO 128-25:1999 as IS 10714 (Part 25).

This standard specif.~s application rules and basic conventions for the types of lines on shipbuildingdrawings.

The other parts of this series are given as follows:

IS 10714 (Part 20) :2001 Technical drawings — General principles of presentation: Part 20 Basicconventions for lines

IS 10714 (Part 21 ) :2001 Technical drawings — General principles of presentation: Part 21 Preparationof lines by CAD systems

The text of ISO Standard has been approved as suitable for publication as an Indian Standard withoutdeviations. Certain conventions are, however, not identical to those used in Indian Standards. Attentionis particularly drawn to the following:

a) Wherever the words, ‘International Standard’ appear, referring to this standard, they should beread as ‘Indian Standard’.

b) Comma ( , ) has been used as a decimal marker while in Indian Standards, the current practiceis to use a point ( . ) as the decimal marker.

in this adopted standard, reference appears to certain International Standards for which Indian Standardsalso exist. The corresponding Indian Standards, which are to be substituted in their places, are listedbelow along with their degree of equivalence for the editions indicated:

1 scope

This part of ISO 128 specifies application rules and basic conventions for the types of lines on shipbuildingdrawings.

2 Normative references

The following normative documents contain provisions which, through reference in this text, constitute provisions ofthis part of ISO 128. For dated references, subsequent amendments to, or revisions of, any of these publications donot apply. However, parties to agreements based on this part of ISO 128 are encouraged to investigate thepossibility of applying the most recent editions of the normative documents indicated below. For undatedreferences, the latest edition of the normative document referred to applies. Members of 1S0 and IEC maintainregisters of currently valid International Standards.

ISO 128-2Q 1996, Technical drawings — General principles of presentation — Pafl 20: 6asic conventions for lines.

ISO 6428:1982, Technical drawings — Requirements for microcopying.

3 General principles

The basic types of lines, their designations and dimensions as well as general rules for dra~hting of lines arespecified in ISO 128-20.

The requirements for microcopying are specified in ISO 6428.

4 Types of lines and their application

The different types of lines and their application are described in Table 1.

The first part of the line number in Table 1 corresponds to the basic type number, in accordance with ISO 128:20.

~It is recommended to use only one type of line on one drawing.

] The decision to use the type of line 02.2.3 or 01+03 is left to the shipyard.

Examples of applications are given in annex A.

5 Line widths and line groups

Two line widths are normally used on shipbuilding drawings. The proportions between the line widths should be notsmaller than 1:2. A proportion of 1:3 is also allowed.

The line groups are specified in Table 2.
