1. CEN and ISO Standards on equipment for plant/crop protection
Tom Bals
Member of CEN/TC 144/WG3 and ISO/TC 23/SC 6
(also BSI AGE 15 and ASABE PM 23)

2. Regulation on plant protection equipment: the European context

3. Regulation on plant protection equipment
Safety
Machinery Directive
In place since 1995
Revised version in place since January 2010
Directive 2006/42/CE (replacing 98/37/EC), amended by 2009/127/EC
Environment
National regulations
New European regulations
Thematic strategy on sustainable use of pesticides
Road travelling rules
National regulation

4. Thematic strategy on sustainable use of pesticides
Machinery Directive amendment (2009/127/EC)
Plant protection equipment – covers safety to the operator of new machines
Directive on sustainable use of pesticides (2009/128/EC)
Includes environmental protection requirements for new plant protection equipment
Includes the inspection of plant protection equipment in use

5. Implementation of European Directives on plant protection equipment

6. The new approach European Directives “old approach”
They set:
Objectives
Solutions
Methods of verification
European Directives “new approach”
They set only objectives called “essential requirements”
Reference can be made to European harmonised Standards as a means of compliance

7. European (EN) Standards
Developed by CEN
CEN TC 144 is the technical committee for tractors and agricultural machinery
Within TC 144, WG3 (mobile machines) covers plant protection equipment
Members of the WGs are national voluntary experts (equipment manufacturers, technical institutes and laboratories, authorities, etc. nominated by their National Standardisation Body - BSI in the case of the UK – although BSI activity in this area is run by Keith and Lesley Hawken of AEA)
EN Standards can be developed in cooperation with the International Standards Organisation, ISO (via the Vienna agreement) – under the lead of CEN or ISO

8. EN harmonised Standards
Developed by CEN to support a European Directive
Published in the Official Journal of the EU
Conformity with a harmonised standard gives a presumption of conformity to the corresponding Directive
Directive → essential requirements
Harmonised Standard → functional or technical requirements

9. Example: sprayer cleaning
Amendment to Machinery Directive
→ Essential requirements
“The machinery must be designed and constructed to allow its easy and thorough cleaning without contamination of the environment”
EN ISO Standard
Technical requirements
Roughness of internal walls of the main tank
Rinsing tank
Device for the internal rinsing of the main tank
Residual volume
Dilution of the residual volume
Instruction manual

15. Conclusions:
EN harmonised Standards which support the SUD have been published or are under development with respect to most vehicle- mounted sprayer types
Standards are essential because they facilitate the implementation of regulation and contribute to harmonisation between countries
Standards are also a tool which regulation can build on
EN Standards generally refer to test methods defined by ISO Standards

16. International (ISO) Standards
EN Standards frequently refer to ISO Standards
In general, EN Standards set performance limits and ISO Standards define test methods

31. ISO/TC 23/SC6 International membership Strong expertise
Official recognition
The best platform for the development of high quality international Standards in the field of plant protection equipment

32. Key issues being addressed in ISO/TC 23/SC 6 Action Plan
More demanding regulation
New strategies for the use of pesticides
Globalisation
Representativeness
Communication
Organisation
New work item prioritisation

33. ISO/TC 23/SC 6 Action Plan Vision, mission and values
Work program management
Communication
Globalisation
Organisation

34. The mission
“To develop high quality Standards that support global harmonisation in the field of plant protection equipment, including the safety of the operator and the environment.”

35. Work programme management
SC 6 scope
“standardisation” of equipment for crop protection, pest control and liquid fertilizers”
→ SC 6 activities focussed on equipment
Set up priorities
Select and prioritise new projects to be launched
Improve the process for assessing new projects
Check list with 10 key points for the assessment of new projects:
Scope
Benefits for the user
Support of regulation etc.

36. Communication / globalisation
Rotate SC 6 meetings regionally
Coordinate the organisation of meetings
Promote the organisation of web conference meetings
Organise information and exchange meeting on application techniques

37. Conclusions:
Sprayers will have in the future to comply with more and more demanding regulations with respect to environmental protection, operator safety and consumer issues
International Standards provide essential support for regulation and global harmonisation – with countries such as US, China and Brazil now involved in ISO and using ISO (and sometimes even European) Standards
ISO/TC 23/SC 6 is the best platform for the development of international high quality Standards in the field of plant protection equipment
ISO/TC 23/SC 6 will in the future focus its strategy on effective work program management, reinforced communication and globalisation
