ICS 17.140.20; 65.060.01

FAD 11

NATIONAL FOREWORD

This Indian Standard (Part 2) (Second Revision) which is identical to ISO 7216 : 2015 'Agricultural and forestry tractors - Measurement of noise emitted when in motion' issued by the International Organization for Standardization (ISO) was adopted by the Bureau of Indian Standards on the recommendation of the Agricultural Machinery and Equipment Sectional Committee and approval of the Food and Agriculture Division Council.

The Indian Standard (IS 12180) was first published in 1987 with the title 'Method for noise measurement of agricultural tractors' and was based on ISO 5131 : 1982 and ISO/DIS 7216. In the first revision in 2000, the standard was split into two parts with the general title 'Tractors and machinery for agriculture and forestry - Noise measurement - Method of test'. Part 1 was an identical adoption of ISO 5131 : 1996 covering method for the measurement of noise at the position of the operator(s) of a tractor or machine used in agriculture and forestry and Part 2 was an identical adoption of ISO 7216 : 1992 covering method for the measurement of noise emitted by wheeled tractors or self-propelled machine used in agriculture and forestry while in motion.

The second revision of the standard (Part 2) has been undertaken to align with the latest version of ISO 7216 published in 2015.

The text of ISO standard has been approved as suitable for publication as an Indian Standard without deviations. Certain conventions are, however, not identical to those used in Indian Standards. 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.
