A CALIBRATION LABORATORY’S INTRODUCTION TO INTERNATIONAL
ACCREDITATION SERVICE, INC.
Why Accreditation?
Laboratories and manufacturers in every field depend on the technical competence of calibration
providers to ensure accurate and consistent measurements. The measurement may involve somethingas simple as determining the correct volume and weight of a substance or as complex as determining
the trajectory of a trip to Mars. Because proper calibration depends on trained and qualified personnel, it
is imperative for calibration providers to supply proof of their expertise. International Accreditation
Service’s calibration laboratory accreditation program provides the evidence needed by your customers.
IAS accreditation provides an independent verification of the technical competence of the personnel,
metrological traceability of equipment, suitability of calibration methods, and the effectiveness of themanagement systems of calibration providers. IAS accredits calibration providers to the internationallyaccepted standard ISO/IEC Standard 17025, General requirements for the competence of testing andcalibration laboratories.
Benefits of IAS Accreditation• IAS accreditation helps calibration laboratories meet their customers’ demands for evidence oftechnical competence.
• IAS is committed to operating a cost-effective laboratory accreditation program that ensures the servicesof accredited laboratories are consistent and of high quality.
• IAS accreditation provides proof of compliance with ISO/IEC Standard 17025• IAS accreditation is independent and objective, and is based on a transparent accreditation processincorporating open public hearings for development of accreditation criteria for calibration laboratories.
• IAS accreditation provides evidence that calibration laboratories provide technically valid results byrendering competent and consistent services in line with international standards.
• IAS places tremendous importance on the training and qualifications of its assessors. This leads to ahigh level of assessor competency and technical expertise.
• With its knowledge base and team of technical experts, IAS helps to improve the quality of accredited
calibration laboratories.
• IAS facilitates proficiency testing and interlaboratory comparisons that laboratories use todemonstrate their technical competence. IAS provides independent feedback concerning a laboratory’s
actual performance which serves as a tool to make improvements.
• IAS provides international recognition to their accredited laboratories by virtue of IAS’s signatory
status in the Mutual Recognition Arrangements (MRAs) of the International Laboratory Accreditation
Cooperation (ILAC) and the Asia Pacific Accreditation Cooperation (APAC).

The Accreditation Process
IAS accredits calibration laboratories by verifying technical competence and assessing their management
systems to ISO/IEC Standard 17025. The process for becoming an IAS-accredited calibration laboratory
begins with the calibration laboratory’s submittal of an application, applicable fees and its management
system documentation. An IAS accreditation officer is selected to partner with the laboratory throughout
the accreditation process, beginning with a review of the management system and the requested scopeof accreditation. Once the management system has been reviewed, IAS selects an assessment team
based on the requested scope of accreditation. The assessment team conducts an on-site assessmentof the laboratory, which includes the witnessing of calibrations, and develops an assessment report. Oncea laboratory has satisfied IAS accreditation requirements, compliance with ISO/IEC Standard 17025 anddemonstrated technical competence, an accreditation certificate is issued.
About IAS
International Accreditation Service, a subsidiary corporation of the International Code Council, assesses
and accredits competent calibration and testing laboratories. The IAS testing and calibration laboratory
accreditation programs are recognized internationally by the International Laboratory Accreditation
Cooperation (ILAC) and the Asia Pacific Accreditation Cooperation (APAC). In operation since 1975, IAS
is a nonprofit, public-benefit corporation and one of the oldest accreditation bodies of its type.
