SEED TESTING INTERNATIONAL OCTOBER 2026
• ACCREDITATION 
Revision of ISTA 
Accreditation Standard
The revised version of the ISTA Accreditation 
Standard (8.0) is now in force. At the February 
2026 ECOM meeting, the revised Directives 
Acc-D-06B for ‘Accreditation of Laboratories 
and Sampling Entities with Sampling Units 
at Multiple Sites’; Acc-D-01 for ‘Termination, 
Suspension and Withdrawal of ISTA 
Accreditation’; and Acc-D-07 ‘Accreditation 
and Scope of Accreditation Policy’, were 
approved with validity from 16 March 2026. 
These directives are posted on the ISTA website 
(see www.seedtest.org/en/services-header/
documents/accreditation-documents.html).
Training and Education
As an outcome of the auditors’ workshop 
organised in Poznan in December 2023,  
a guideline for the calibration of laboratory 
equipment (balances/scales and thermometers) 
is in progress, and we hope it will be available 
no later than the end of 2026. This is being 
created with the great support of Steve Jones, Joel 
Léchappé, Harry Nijenstein and Stephan Brière. 
The guideline will be submitted for checking 
and opinions to the ISTA Technical Committees 
(TCOM) and as soon as it is finalised, will be 
available on the ISTA website for free viewing  
and download.
Another important contribution of the 
department to ISTA’s training and education 
programme was a ‘Quality Assurance Workshop 
for Beginners’, delivered in French in November 
2025 in Dakar, Senegal, with the support of the 
Food and Agriculture Organization of the United 
Nations (FAO). For 2026, a similar workshop will 
be run in Spanish in Mexico.
In the same area of quality assurance, three 
webinars were given in 2025 and so far, one 
in 2026. For each webinar we had over 200 
participants, with more than 880 participants  
in total across all webinars.

A webinar on the ‘ISTA Standard PT Programme 
Plan 2026–2028’ was organised by the Proficiency 
Test (PT) administrator at the ISTA Secretariat in 
collaboration with the PT Committee Chair and 
Vice-Chair. All past webinars are available 
to view on the ISTA YouTube channel 
(go to www.youtube.com/@
internationalseedtestingas8438).
In October 2026 we plan another webinar focused 
on changes to the ISTA accreditation scope.
Two projects have also started for the 
Accreditation and Technical Department:
• Project 1: Accreditation of ISTA laboratories 
for seed health tests – a new approach; with the 
support of the Seed Health (SH) Committee, 
ECOM–SHWG, ECOM–AWG
	
−  From validated methods to more method-	
based accreditation
• Project 2: Submitted sample storage after testing; 
together with the Seed Storage Committee and 
the Bulking and Sampling Committee; other 
ISTA TCOMs will support the project, and the 
conclusion will improve requirement 2.5.4.7 
of the International Rules for Seed Testing 
(ISTA Rules)
A new LinkedIn page, ‘ISTA accredited members 
community’ has now been launched. We hope 
that this will be beneficial for all ISTA accredited 
members. Finally, the excellent support received 
from the ECOM-AWG during the past year for 
many specific cases needs to be commended.
We the auditors would like to mention the 
support and the good communication with the 
ISTA TCOMs. Their answers to questions raised 
by auditors and laboratories during audits and 
when studying the ISTA Rules, have helped us to 
improve and clarify aspects for future audits also 
to suggest possible changes to the ISTA Rules.
