International Rules for Seed Testing

The International Rules are ISTA primary tool to promote uniformity in the seed testing industry.

Featuring 19 sections, the International Rules for Seed Testing have definitions and standardised methods to be used in sampling, testing seed lot quality and reporting results for international trade. The Rules are a useful reference guide to germination conditions and methods for over 1,000 species. 

The ISTA Rules are voted, amended and approved annually at the Ordinary General Meeting after considering the Technical Committees recommendations.
