International soil correlation implies international exchange of analytical data and this requires international comparability of data. A critical analysis of the reliability of laboratory data is important to give the user an idea about the error range all figures are associated with. A chemical or physical analysis determines a numerical yalue of a paranieter T his parametei has a 'true' value which is usually unknown and which the analyst tries to approximate as closely as possible applying certain procedures. In practice the results are scattered around this 'true' value. -
Book (stand-alone)Guidelines on standards for agricultural pesticide application equipemnt and related test procedures
Portable (operator-carried) sprayers. Vol 1
2001The FAO guidelines on standards are based on existing international, European and national standards and other published references. They also draw on the in-depth knowledge and experience of international sprayer standards of the experts assigned to the project and on the authors’ experience of pesticide application in the developing world. The guidelines on standards consist of detailed specifications and requirements, supported by test procedures to measure compliance with the FAO standard, for the major types of agricultural pesticide sprayers manufactured or used in FAO member countries. These standards reflect current manufacturing practice, other national and international standards and the practical reality in the field in member states. The aim of the standards guidelines is to provide manufacturers and governments with a practical and consistent quality assurance system. Each member country can then decide on the form and speed of introduction of the respective guidelines into national practice and into legislation where appropriate.
