NATIONAL FOREWORD

This Indian Standard (First Revision) which is identical to ISO 12509 : 2023 'Earth-moving machinery and rough-terrain trucks - Lighting, signaling and marking lights, and reflex reflectors', issued by the International Organization for Standardization (ISO) was adopted by the Bureau of Indian Standards on recommendation of the Earth Moving Equipment and Material Handling Sectional Committee and approval of the Mechanical Engineering Division Council.

This standard was first published in 2018.

The following major modifications have been incorporated to the revision of the standard:

a) In the Scope, it was clarified that rough-terrain trucks are included;

b) The term 'earth-moving machines' was replaced with 'machines' throughout this document;

c) The normative references were updated;

d) In 3, several definitions were revised and several were removed as they no longer appear in this document;

e) In 4, technical changes were made including a re-write of 4.1.6 and the addition of 4.1.10, with Table 4-1 and addition of clauses moved from the former C.0;

f) In Annex A, Table A-1 was revised, including the removal of the footnotes;

g) In Annex B, the annex title was clarified and Figure B-1 was revised;

h) Annex C from the previous edition was removed;

j) Annex D from the previous edition was removed;

k) In Annex E (now Annex C), there were technical changes to most of the clauses, including modifications to the text, the figures and the tables. Configurations text was removed in most clauses as this information is now covered in 4.1.10 and Table 4-1. The exception for steeltracked or steel-pad-foot was moved to Table A-1. The content of Clause C.0 has been moved to other sections in this;

m) In Annex F (now Annex D), the figures and keys were revised; and

n) In Annex G from the previous edition was removed.

The text of ISO standard has been approved as suitable for publication as an Indian Standard without deviations. Certain terminologies and conventions are, however, not identical to those used in Indian Standard. Attention is particularly drawn to the following:

a) Wherever the words 'International Standard' appear, referring to this standard, they should be read as 'Indian Standard'; and

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