To secure NATA accreditation, NATA assesses your laboratory against defined criteria, which are a mix of both international standards and local criteria, developed by NATA.

There can be as many as 20 to 30 documents that you need to go through to identify which requirements may be applied to your laboratory. If you have contacted NATA and they told you to download all of these documents and have a look through them you might be feeling overwhelmed right now. I don’t blame you!

Here are the documents that NATA accreditation requires.

Fields of Testing

NATA’s accreditation requirements vary according to what kind of testing you are doing. Check out NATA’s Fields of Testing.

The requirements documents include:

  • ISO 17015 General requirements for the competence of testing and calibration laboratories. Or, ISO 15189 Medical laboratories – Requirements for Quality and Competence.
  • Standard Application Document (affectionately known as the SAD!)
  • (Field) ISO/IEC 17025 Application document (you guessed it – FAD)
  • General Equipment Tables
  • NATA Rules
  • NATA Procedures for Accreditation
  • 20 – 30 policy circulars, technical circulars, annexes and information papers.

The main criteria documents, so you know where to look for the information you need, are:

These international standards outline requirements for laboratories that can be used to demonstrate they operate competently, and are generating valid test results. These are general requirements, with no prescriptive schedules or test requirements. The emphasis is on monitoring risk and opportunities. The management system requirements in both of these standards are closely aligned with the requirements of ISO 9001.

Standard Application Document

The ‘SAD’ for ISO 17025 laboratories only, contains some specific additional criteria that NATA has developed, based on their rules and their interpretation of ISO 17025. It also contains a lot of recommendations and examples, none of which are mandatory. Be careful of the wording in it – it doesn’t stick to ‘must’ and ‘should’ in the way that ISO 17025 does, which can lead to some vigorous discussions with NATA staff members at times.

ISO/IEC 17025 Application Document

ISO 17025 Application Document for your field of testing  (or ISO 15189 Supplementary Requirements for Medical Testing) is probably going to be a lot more interesting to you. There is a separate one for each field, and you will find that the ‘interpretive criteria’ in there relate to things you may know something about. There will also be a list of equipment and recommended calibration frequencies – something that is not mandatory to follow, but can be a useful guide.

General Equipment Table

This gives you a suggested equipment calibration frequency for a number of ‘common’ pieces of equipment.

NATA’s Rules

These contain the information you need to know about ‘NATA endorsed’ test reports – when you can issue them and when you can’t. There is also information about how to use your NATA accreditation in advertising material. The rest of the rules are about how NATA operates, it’s board, what happens if NATA thinks that your laboratory should not be accredited any more (‘suspension’) and so on. It’s worth reading through them when you are away from the day-to-day business of the lab, and thinking about how the rules apply in your situation.

Policy Circulars, Technical Circulars, Annexes and Information Papers

These contain specific information on particular topics. As they can contain additional accreditation criteria, you can’t ignore them. Many have self-explanatory titles, so you can quickly decide if they are relevant to you. Others you really have to read through to find out what they are about.
