Abstract
An ISO performance standard dedicated to protective clothing for operators handling plant protection products was published in 2011. The standard requires measuring penetration through fabrics with a test chemical representative of plant protection product with the highest penetration. In Europe, the EC Regulation No 1107/2009 requires data to substantiate that the protective clothing specified on plant protection product label provides adequate protection against that product. This can be done by testing with the specific product or through extrapolation. A study was conducted to develop a database to better understand the penetration behavior of plant protection products through protective clothing compared to the reference test chemical for ISO 27065. The aim of the study was to determine whether testing with the reference test chemical for ISO 27065 is sufficient to serve as the basis for extrapolations. The study was also used to select a product to be used as the basis for the development of a surrogate, as the current ISO 27065 test chemical is planned to be changed. A fabric that met ISO 27065 Level C1 requirements was tested with ISO 27065 test chemical as well as 65 commercial plant protection products that represent a wide range of formulation types. A sub-set of 12 plant protection products was selected for further testing with two additional Level C1 fabrics. Based on the statistical analysis, formulation types, for which there is data in the database, could be used for extrapolation purposes. In addition, a reference product was selected as the basis for the development of a non-commercial surrogate test chemical.

The study was coordinated by the International Consortium for PPE for Pesticide Operators and Re-entry Workers. Testing conducted in France was funded by Ecophyto (the French action plan to reduce and secure pesticide use, in compliance with the Sustainable use EU directive) for Part 1 and by UIPP for Part 2. Funds provided by Fundag were used by IAC for testing conducted in Brazil. We thank members of UIPP for the coded Plant Protection Products and to BASF for providing the pendimethalin products. Special thanks to those members and sponsors who provided input and support for the project, and to Sophie Chenavas (CTC Groupe) and Ana Flavia Villa (Instituto Agronômico) for their diligence in conducting the tests.
