Central Science Lab seed testing receives accreditation

The Central Science Laboratory (CSL) in York has been awarded international accreditation for its seed testing services.

CSL has been recognised by the International Seed Testing Association (ISTA) for five key seed quality indicators - purity and determination of other seeds, germination, moisture content determination, and weight determination.

The laboratory, which is a DEFRA agency carrying out research concerning protection of UK agriculture, food and the environment, is one of only three in the UK to be accredited. 

CSL deals with over 10,000 seed samples a year, permitting the issuing of phytosanitary certificates necessary for exporting seeds from the UK. 

The new ISTA accreditation means that CSL can now also issue ISTA Orange International Seed Lot Certificates (OIC) and Blue International Seed Sample Certificates (BIC), which are required by many countries around the world before they will allow the import of seeds.

CSL’s Kelvin Hughes says: “Accreditation is only awarded to laboratories that have the right expertise, methodology and quality assurance systems to carry out seed testing procedures in accordance with their International Rules for Seed Testing – it’s a real feather in our cap.  The fact that we can now issue OIC and BIC certificates is great news for our clients.”

ISTA (International Seed Testing Association) is an independent, non-profit association dedicated to developing, adopting and publishing standard procedures for sampling and testing seeds.
