Comprehensive Guide to ISO 5725-2 Repeatability and Reproducibility for Pesticide Tests Testing Service Provided by Eurolab

ISO 5725-2:1994(E) is a standard that defines the methods for determining repeatability and reproducibility of test results in measurement processes. This standard is applicable to pesticide tests, which are conducted to evaluate the efficacy and safety of pesticides.

Legal and Regulatory Framework Surrounding ISO 5725-2 Testing

The legal and regulatory framework surrounding ISO 5725-2 testing is complex and multifaceted. In the European Union (EU), the use of pesticides is regulated by the EUs Plant Protection Products Regulation (EU) No 1107/2009, which requires that pesticide products meet specific safety and efficacy standards.

International and National Standards

The following international and national standards apply to ISO 5725-2 testing:

  • ISO 5725-2:1994(E)

  • ASTM E177-16 Standard Practice for Sampling Strategies for Establishing Conformance to Specifications
