FOREWORD

ThIs Indian Standard ( Fourth R.evision ) was adopted by the Bureau of Indian Standards, after thedraft finalized by the Crop Protection Equipment Sectional Committee had been approved by theFood and Agriculture Diyision Council.

This standard' was first published in 1966 and subsequently revised in 1972, 1974 and 1982. The standardhas been revised again to incorporate certain improvements found necessary in the Ii.ht of the modil­cations sUlgested by the testios authorities and manufacturers. This revision incorporates amon,others the following:

a) Amendment NJ.J. 1 to 3 issued to earlier version of the standard,b) Bditorial changes including updating of referredstandards,c) Material of construction are modified and requirement of chemical composition of brass

casting components as per relevant Indian Standard is to ensure conformity,d) Provision for use of adjustable hydraulic spray nozzle,e) .Order of testing,f) Provision for supplyiq cut-off device as per purchaser's requirements, andg) Test for piston made of synthetic rubber.

This standard was earlier published in two parts. With the withdrawal of IS 3906 (Part 2 ) : 1979'Diaphragm type band-operated knapsack sprayer', this revision has been published as single standardwithout any part.

The figures given in the standard are meant only for illustration of the components. These should notbe considered as suggestive of any standard design.

In preparation of this revision, considerable assistance has been derived from the pest control equip­ment industry and the testios authorities.

For the guidance of the purchaser, Annex A has been complied. Besides quoting the number of thisstandard. the details desired in the Annex may also be stated. '

For the purpose of deciding whether a particular requirement of this standard is complied with, thefinal value, observed or calculated, expressing the result of a test or analysis, shall be rounded offin accordance with IS 2 : 1960 'Rules for rounding off numerical values ( reviled )'. The number ofsignificant places retained in the rounded ott value should be the same as that of the specified value inthis standard.
