The Test

The full test consists of 47 test items, the first 30 of which must be satisfied to receive a pass certificate. The subsequent 10 are advisory and the final 7 are optional test elements.

This comprehensive test covers all the application components of the sprayer to ensure the machine is working correctly and efficiently with further considerations of safety for the sprayer operative and the environment.

Major components of the sprayer tested include control systems, hoses and pipework, nozzles and nozzle control systems, filters, pumps, tank, chemical induction systems and booms. In addition it is recommended that computer control systems are checked to maximize efficiency and to satisfy the calibration element of crop assurance schemes.


Be Safe

The NSTS will ensure your sprayer equipment and agrochemicals are being used in a manner that is safe for the sprayer operative, safeguarding your employees or contractors against accident and bringing peace of mind to you that risk assessment has been carried out on your machinery.

Furthermore the NSTS certificate provides useful documentation for insurance companies and offers confidence to your sprayer operatives in your diligence and due-care as an employee.


Be fully compliant

The NSTS test is a requirement of the major UK crop assurance schemes and of supermarket protocols.

The NSTS test will become a requirement for all boom sprayers by 2016 under the requirements of the Sustainable Use Directive and be retested every five years until 2020 when the requirement for re-testing reduces to every three years.  The SUD is mandatory throughout the EU.

Furthermore, a NSTS certificate will indicate to clients your adherence to best practice procedures and reflect favourably upon your professionalism.
