Abstract:
The large variety of phyto-sanitary equipment and plants existing on
the Romanian market (various brands, various levels of wear), the users’
training level and the requirements Romania has for its accession to the EU
demand the adoption of some precise regulations concerning the control of
the spraying equipment according to the present-day international norms.
This paper presents the situation nowadays in Romania in the filed of the
control of the spraying devices and the concerns of INMA with respect to the
adoption and implementation of the European norms. In this respect, the
functional prototypes of two stands for the control of the characteristics of
the spraying machines for the filed works, orchards and vineyards
respectively have been achieved. Both stands have small dimensions, easy to
move, are built with anticorrosive materials and enable performing tests
directly at the beneficiary. The principle underlying the functioning of this
measuring equipments is electric conductivity, respectively, closing of the
electric circuit through the column of liquid in the test tube when it is filled
up. The developed methods and working procedures ensure greater precision
of measurement, reducing testing time and certifying the obtained
measurement values, automatically printed and graphically represented in a
Test Result Bulletin.
The functional prototypes of the two stands represent the first step
towards the introduction and implementation of the European norms in the
control of the sprayers. The advantages of these stands for the testing and
checking consist in: increased measuring accuracy, reduced trial time,
increased reliability of results, automated printout of the Test bulletin
including the test results, easily used in the field.
