Approved is better!

SKL (Foundation for Quality Control of Agricultural Equipment) in Wageningen (the Netherlands) is the Dutch organisation for testing agricultural machines in use.


Easy registration of the results of an inspection, uniform and complete filled-in testing reports and a complete overview of the performed inspections are the main advantages of the use of a software system for registration.

For the registration of the performed sprayer-inspections and certified workshops for the inspections SKL, together with her software partner SONIMA, has developed a complete, flexible and reliable web-based registration system. SKL is using this system since 2007.

The registration system for sprayer-inspections can register inspections for:


  • Field-crop sprayers (in line with EN-ISO16122:1)
  • Air-assisted sprayers for bush and tree crops (in line with EN-ISO16122:2) 
  • Fixed and semi mobile sprayers (in line with EN-ISO16122:3)
  • Other tailor made inspection reports 

The main purposes of the registration system are:

  • Registration of inspections, sprayers and owners
  • Registration of all certified testing stations and test-operators
