This standard specifies the criteria which must be fulfilled by laboratories and sampling entities in order to obtain ISTA accreditation, and to maintain their status as an ISTA accredited member and their authorisation to issue ISTA certificates. This standard covers all the steps from sampling to issuance of ISTA certificates.
For the purpose of this standard, the term ISTA "accredited member" refers to the accredited laboratory and accredited sampling entity.
ISTA Certificates can be issued only by accredited laboratories having seed testing methods included in their scope of accreditation.
Technologies new to the ISTA Rules are accepted, whether these are the basis of new methods or new tools within existing methods, provided they can meet the specific requirements that are prescribed case by case.
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 requirements outlined in this Standard, show competence by successfully completing the pre-accreditation proficiency testing, and demonstrate competence during the assessment of the candidate for accreditation/accredited member’s facilities by auditors appointed by the ISTA Head of the Accreditation and Technical Department.
Applicants pay for the services rendered during the accreditation assessment (i.e., proficiency assessment, on-site assessment, partially remote assessment or remote assessment in specific conditions, and evaluation of documents), and also pay an annual fee for being an accredited member of ISTA.
A partially remote audit or a complete remote audit can only be accepted on an exceptional basis and must be approved by the ISTA Executive Committee (ECOM).
ISTA accreditation is formally granted by ISTA after the Executive Committee is satisfied that the accreditation process has been properly executed, and that the candidate for accreditation/accredited member has met the requirements of this Standard.
1. Purpose and scope
1.1. This ISTA Accreditation Standard has been prepared to meet the specific needs of ISTA, its accredited members and the international seed trade. 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 members. Accreditation can only be granted for methods stated in the ISTA Rules including new technologies and performance approved methods as defined therein.
1.3. Care has been taken to make the Standard suitable for accredited members in different countries, and to require only that 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 accredited member to carry out its work in such a way as to meet the requirements of ISTA.
2. Definitions
The 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 member accreditation system and grants accreditation (ISTA).
Auditors: Persons appointed by or recognised by the Association to carry out audits.
Audit: Systematic and documented process for obtaining audit evidence and evaluating it objectively to determine the extent to which audit criteria are fulfilled.
Certificate: Document that presents test results and other information relevant to a test.

ISTA Rules: ISTA International Rules for Seed Testing, published by the International Seed Testing Association; includes standardised definitions, methods and principles to be used in evaluating seed for transactions in international trade.
ISTA Certificates: Blank paper ISTA Certificates and access to blank electronic ISTA Certificates for seed analysis is controlled by ISTA. Both blank paper, and access to blank electronic certificates, are only provided to and can only be issued by accredited laboratories.
Accredited member: entity performing a) seed testing and sampling, b) seed testing only or c) sampling only.
Sampling entity: an ISTA member accredited/authorised by ISTA for seed sampling only.
Method: Generic description of a logical sequence of operations used in a particular test, specifying the attribute to be examined, the species, the measuring principles used as well as the possible range, dimension and unit of results.
Proficiency testing: Methods of checking laboratory testing performance by means of inter-laboratory tests, i.e., the ISTA Proficiency Test Programme.
Quality manual: Collection of documents which describes quality policy, quality management system and quality practices of the accredited member.
Reference materials: Materials which provide essential traceability and are used to demonstrate the accuracy of results, to calibrate/verify equipment, to monitor accredited member 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 an accredited member to obtain seed samples.
Sampling: A defined ISTA 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).

All sampling, measuring, and testing equipment, for which this is possible, must be adequately calibrated, verified and approved as fit for purpose before being placed into service and monitored regularly afterwards. A document must be kept in which are recorded the results of each calibration, verification, service, and repairs (see 5.2.7e and f). Calibration, verification and servicing of equipment must be performed according to an established programme.
5.3.2. The overall programme of calibration/verification of equipment must be designed and operated so as to ensure that, wherever applicable, measurements made in the accredited member are traceable to national and international standards of measurement.
5.3.3. Appropriate calibration samples, reference materials and reference standards of measurement must be held by the accredited member, or a service provider, and be used for calibration and reference purposes.

10.8. Audits
10.8.1. At least yearly, the accredited member must perform internal audits of its activities in accordance with a predetermined schedule and procedure. Audits must be performed in such a way that they verify the accredited member's continuous compliance with this Standard and its quality management system. The internal audit programme must address all elements of the quality management system, including the testing and sampling activities. It is the responsibility of the quality manager to plan and organise audits as required by the schedule and requested by the organisation management. Such audits must be carried out by trained and qualified staff who are, wherever resources permit, independent of the activity to be audited. The audit report and related checklist must be kept and available.
10.8.2. When audit findings cast doubt on the effectiveness of the operations or on the correctness or validity of the accredited member’s test results, the accredited member must take timely corrective action, and must notify clients in writing if investigations show that the accredited member results may have been affected.
