addressing uncertainty in oil and natural gas industry greenhouse

using standard methods, non-standard methods, and laboratory-developed methods. This standard may be
applied to all organizations performing tests and/or calibrations, including both internal companies’
laboratories as well as external contract laboratories.
ISO/IEC 17025:2005 is applicable to all laboratories regardless of the number of personnel or the extent
of the scope of testing and/or calibration activities. When a laboratory does not undertake one or more of
the activities covered by ISO/IEC 17025:2005, such as sampling and the design/development of new
methods, the requirements of those clauses would not apply.
As part of compliance with ISO/IEC 17025:2005, laboratories that want to be accredited to this standard
are mandated to seek feedback, both positive and negative, be it from in-house users or from external
customers. The information gathered is expected to help laboratories improve their management systems,
their testing and calibration activities, and customer service. The ISO standard seeks to improve
laboratory measurement proficiency and accuracy by continual improvement of the effectiveness of
laboratory management systems and the implementation of quality policy, quality objectives, internal
audits, data analysis, corrective and preventive actions, and periodic management review.
