This Standard specifies the criteria which must be fulfilled by laboratories in order to obtain and maintain their status as an International Seed Testing Association (ISTA) accredited laboratory and their authorisation to issue ISTA Certificates. This Standard covers all steps from sampling to issuance of ISTA Certificates.
Application forms are obtainable from the ISTA Secretariat. In order to obtain accreditation duly completed application forms must be lodged with the ISTA Secretariat. The applicant must meet the required organisational and other requirements outlined in this Standard, show competence by successfully completing the pre-accreditation proficiency testing, and demonstrate competence during the on-site assessment of the laboratory’s facilities by auditors appointed by the ISTA Executive Committee.
Applicants pay for the services rendered during the accreditation assessment (proficiency assessment, on-site assessment, and document evaluation), and pay an annual fee for being an accredited member of ISTA.
ISTA accreditation is formally granted by ISTA after the Executive Committee has been satisfied that the accreditation process has been properly executed, and that the applicant laboratory has met the requirements of this Standard.
1. Purpose and scope1.1. This ISTA Laboratory Accreditation Standard has been prepared to meet the specific needs of ISTA, its member laboratories and the international seed trade. It is based on internationally accepted principles for accreditation. It has been approved by the ISTA Executive Committee under provisions of Article 15(c)15 of the Articles of the International Seed Testing Association.
1.2. The current version of the ISTA International Rules for Seed Testing forms an integral part of the Standard, as the Rules define the methods which must be used for the issuance of ISTA Certificates by accredited laboratories. Accreditation can only be granted for methods stated in the ISTA Rules including performance approved methods as defined therein.
1.3. Care has been taken to make the Standard suitable for laboratories in different countries, and to require only that which is necessary to ensure that test results are reliable.
1.4. Only the English version of this Standard is official.
1.5. It is the responsibility of the laboratory to carry out its work in such a way as to meet the requirements of ISTA.
2. DefinitionsThe following terms are used in the Standard:
Accreditation: Formal recognition of technical competence to carry out specific tasks.
Accreditation body: Body that conducts and administers a laboratory accreditation system and grants accreditation (ISTA).
Auditors: Persons appointed by or recognised by the Association to carry out audits.

Quality manual: Collection of documents which describes quality policy, quality systems and quality practices in the laboratory.
Reference materials: Materials which provide essential traceability and are used to demonstrate the accuracy of results, to calibrate equipment, to monitor laboratory performance, to validate methods, and to enable comparison of methods by use as transfer standards.
Sampler: A person trained and experienced in seed sampling who is authorised by a laboratory to obtain seed samples.
Sampling: A defined procedure whereby a representative part of a seed lot is taken to obtain a sample of suitable size.
SI units of measurement (International System of Units): The SI is founded on seven SI base units for seven base quantities assumed to be mutually independent, e.g. length (m), mass (kg).
