The International Rules for Seed Testing are ISTA’s primary instrument to promote uniformity in seed testing. The ISTA Rules have 19 sections that provide definitions and standardized methods to be used in, for example, sampling, testing seed lot quality and reporting results forinternational trade. The ISTA Rules are also a useful reference guide to germination conditions and methods for over 1000 species.

The International Rules for Seed Testing are approved by and amended at ISTA Ordinary Meetings on the basis of advice tendered by the ISTA Technical Committees.
The 2014 edition (effective 1 January 2014) includes the latest changes which were passed at the ISTA Ordinary General Meeting 2013, held at Antalya, Turkey.

Additional information on seed testing can be found in various ISTA Handbooks, however, without having legal character.
