It was necessary for the construction laboratories to adopt the quality management method in their work, in particular the application of the standards of ISO 17025: 2005, Which improve the performance of these laboratories in terms of administrative and technical.

This research includes a statistical study of a sample of construction laboratories, construction contracting companies and project implementation entities in some government departments to determine the factors affecting the reliability of the laboratory tests. The methodology used in the research will provide recommendations and suggestions to help the laboratory staff focus on the factors influencing the Reliability of tests and handling them according to the  ISO 17025: 2005.
