ISO 17025 (For Testing and Calibration for Laboratories) NABL

WHAT IS ISO / IEC 17025 or NABL?

ISO/IEC 17025 is the main standard used by testing & calibration laboratories. Originally known as ISO/IEC guide 25,ISO/IEC 17025 was initially issued by the international organization for the standardization in 1999. It was first published in 2001 & on 2005

Key Steps Toward Accreditation are

  • ISO/IEC 17025 accreditation should be well thought out and well prepared. It can be quite expensive but can also have big benefits.
  • The balance between costs and benefits should be worked out and documented
  • Going for ISO/IEC 17025 will impact the entire laboratory and supporting services such as human resources, documentation and finance departments. Therefore, while the decision to initiate and fund the project will be made by management, all affected departments should be involved in the process
  • The entire process is divided into two phases: Investigation phase and implementation phase. In the investigation phase information is collected to decide if going for accreditation makes business sense
  • Once the decision is made the laboratory develops and implements documentation in preparation for the Accreditation assessment
