The laboratory has a vital role in the research and executive system, and the results of analysis are the basis of many decisions and policies. Due to the role of laboratories in surveying the status of soil resources in the country, the Department of Soil and Water Laboratories was established in1335. Today, standardization is the most important factor in creating, maintaining and improving the quality of systems at a globally acceptable level. The ISO 17025 places a great emphasis on the correct testing method and the correct use of standards, with a strong focus on accuracy, determination of test results, and determination of computational error and results. The purpose of this project is to implement ISO 17025 in the laboratories of the Soil and Water Research Institute. For this purpose, firstly, a strategic committee was established as the main reference for developing the standards in the laboratory. After finalizing the test methods, the documents required by the laboratory were prepared and modified. Selected tests for obtaining the ISO 17025 standard are determination of heavy metals in soil, plant and fertilizer samples and determination of nitrate in vegetables. Then the standard requirements (managerial and technical) were implemented in the laboratory. In the next stage, training courses were held for the laboratory experts. The uncertainty of the results was calculated and the quality control/quality assurance of the results was done. Afterwards, an internal audit was performed to eliminate possible non-compliances. Finally, the final audit will be done by the National Center for Iranian Accreditation.Keywords: Laboratory, standard, ISO 17025, audit, certification.
