  • Goniometric Power Distribution Testing

ISO 17025 is the main standard used by testing and calibration laboratories. While similar to the ISO 9000 (9001, 9002) standards, ISO 17025 adds the concept of competence to the equation and it applies directly to those organizations that produce testing and calibration results.  Laboratories use ISO 17025 to implement a quality system aimed at improving their ability to consistently produce valid results. Since the standard is about competence, accreditation is simply a formal recognition of a demonstration of that competence.  A prerequisite for a laboratory to become accredited is to have a documented quality management system.  Regular internal audits are employed to ensure continuous improvement.

There are two main sections in ISO/IEC 17025 – Management Requirements and Technical Requirements. Management requirements are primarily related to the operation and effectiveness of the quality management system within the laboratory. Technical requirements address the competence of staff, methodology, test/calibration equipment and the test methods. Full validation of test methods and proof of proficiency set this standard apart from ISO 9001 or 9002.

NVLAP is the National Voluntary Laboratory Accreditation Program. It is a National Institute of Standards and Technology (NIST) program in the USA which provides an unbiased third-party test and evaluation program to accredit laboratories in their respective fields to the ISO 17025 standard. NVLAP is in compliance with ISO 17011.

The EPA requires that all ENERGY STAR™ products must be certified by a third-party to ensure consumer confidence in the ENERGY STAR program and label. Product testing must be carried out in an EPA-recognized laboratory that has been verified to meet strict, international standards for quality and competency. Ongoing tests are also required to ensure that products continue to deliver superior energy efficiency and performance. 

Devices carrying the ENERGY STAR service mark generally use 20%-30% less energy than required by federal standards. The ENERGY STAR program was created by the US Department of Energy and US Environmental Protection Agency in 1992 to assist consumers in finding energy efficient products.
