FOREWORD

This Indian Standard ( Fourth Revision) was adopted by the Bureau of Indian Standards. after thedraft finalized by the Crop Protection Equipment Sectional Committee had been approved by the Foodand Agriculture Division 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 light of themodifications suggested by the testing authorities and the manufacturers. The revised version incor­porates, among others, 'the fol1owing:

a) Amendments No. 1 and 2 issued to earlier version of this standard;b) Editorial changes including updating of referred standards;0-) .Material of construction are modified and chemical composition of brass casting components

as per their relevent Indian Standard is to ensure conformity;d) Requirements of spray lance, cut off device, spray nozzle and spray gun and their method of

test which were earlier covered in separate specifications. i.e., IS 7417 : 1982. IS 7458 : 1982,IS 7515: 1982, IS 10064: 1982. IS 10093 : 1982. IS 10107 : 1982 and IS 11776 : 1986 are nowcovered in this standard. With the publication of this standard these standards will bewithdrawn; ,

e) Test for piston made of synthetic rubber; andf) Provision or.~upplying a spray gun and adjustable nozzle.

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

For the guidance of the purchaser, information to be supplied if quoted to the manufacturer is givenin Annex A.

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 off inaccordance with IS 2: 1960 'Rules for rounding oft' numerical values ( revised) '. The number ofsignificant places retained in the rounded off value should be the same as that of the specified value inthis standard.
