Implications of ISO/TEC 17025 (Requirements for the competence of calibration laboratories)

This document essentially  overlaps and complements the requirements of ISO 3000/1. The main thing is to set up a "Quality Manual" which sets out procedures, standards and responsibilities for the various essential functions of the business such as documentation and methods etc. This manual is to be the "prime" living document its contents will be carefully documented and all changes carefully logged. Changes will be necessary to fulfil what is probably the most important aspect of ISO 3000/1, which is the implementation of continuos improvement. In my case setting up the "Quality Manual" will be derived from the "day-to-day" notes kept in my diary and will probably contain many "process" flowcharts.

More specifically in calibration work documentation means procedures which are usually derived from manufacturers tolerances as given in handbooks and catalogues. Records are in the form of calibration checklists. ISO/Tech 75025 contains references to traceably and periodic auditing of work carried out. Procedures could be changed through "Problem Referrals" at the authors last place of work through the Metrology Centre in the USA.  In dealing with the customer the standard states that all requirements should ascertained before starting the work and that there should be good communications so that extra requirements and complaints can be dealt with. The laboratory capabilities and test methods should be sufficient to complete the work. Documentation should record the extent of the contract.
Sub-contracting of work can only be to another laboratory complying with this standard.
              Obtaining UKAS 75025 certification  for each parameter is expensive so on the way to this goal it has been decided  to be as "open" as possible. The customer will be furnished with a measurement "checklist" which gives the maximum information. Most calbration labs retain the "checklist" and only give the measured values on a certificate  if specifically asked for them.
