About IAS

The International Accreditation Service (IAS) provides objective evidence that an organization operates at the highest level of ethical, legal and technical standards. IAS is a nonprofit, public-benefit corporation that has been providing accreditation services since 1975. It is a subsidiary of the International Code Council (ICC), a professional membership association that develops the construction codes and standards used by most municipalities within the United States. IAS accredits a wide range of companies and organizations including governmental entities, commercial businesses, and professional associations. IAS accreditation programs are based on recognized national and international standards that ensure domestic and/or global acceptance of its accreditations.

IAS’ International Credentials

As one of the leading accreditation bodies in the United States, IAS is a signatory to the four primary international organizations that form a unified system for evaluating and recognizing competent accreditation bodies worldwide. These organizations are identified as “cooperations” because they have agreed to cooperate with one another by adhering to a common set of accreditation criteria and to undergo periodic onsite evaluation to determine ongoing compliance with ISO/IEC Standard 17011, General Requirements for accreditation bodies accrediting conformity assessment bodies (CABs). Being a “signatory” means that an accreditation body has been evaluated onsite at its offices, a sampling of the assessments of its accredited entities have been witnessed by peer experts, and that it has been found to comply with international requirements.

These organizations agree to recognize the equivalence of accreditations granted by other signatory member accreditation bodies through a series of Mutual (or Multilateral) Recognition Arrangements (MRAs/MLAs). Once an accreditation body becomes a signatory it is obligated to recognize the certificates or reports issued by conformity assessment bodies accredited by all other signatories within a specified scope. The following organizations make up the unified system for recognition of competent accreditation bodies (ABs):

Asia Pacific Laboratory Accreditation Cooperation (APLAC) MRA –ABs involved in the accreditation of testing laboratories, calibration laboratories, inspection bodies, proficiency testing providers and reference material producers. IAS is a MRA signatory for testing laboratories, calibration laboratories and inspection bodies.

International Laboratory Accreditation Cooperation (ILAC) MRA – ABs involved in the accreditation of testing laboratories, calibration laboratories, inspection bodies, proficiency testing providers and reference material producers. IAS is a MRA signatory for testing laboratories, calibration laboratories and inspection bodies.

International Accreditation Forum (IAF) MLA – ABs involved in the accreditation of management systems, products, services or personnel. IAS is a MLA signatory for product certification and management systems.

Pacific Accreditation Cooperation (PAC) MLA – ABs involved in the accreditation of management systems, greenhouse gas validation or verification bodies, product, service and personnel certification. IAS is a MLA signatory for product certification and management systems.

ILAC and IAF are the apex (worldwide) organizations; APLAC is a region of ILAC and PAC is a region of IAF. Accreditation bodies are recognized depending on the geographic region in which they are located but their signatory status applies worldwide.

What is Accreditation?

Accreditation is a formal, independent verification that a program or institution meets established quality standards and is competent to carry out specific conformity assessment tasks. Conformity assessment tasks may include, but are not limited to, testing, inspection, or certification.

Typically, governmental regulatory agencies such as the Consumer Product Safety Commission (CPSC), the U. S. Environmental Protection Agency (EPA), or the Nuclear Regulatory Commission (NRC) require accreditation to verify the technical competence of organizations like laboratories, inspection bodies, and certification agencies.

Organizations responsible for public safety and welfare such as building departments, hospitals, schools, and police and fire departments also seek accreditation to demonstrate their competence and reliability.

Accreditation has been used for over 50 years as the definitive means of evaluating organizations and is now utilized by all the world’s major economies and many developing economies.

Why Accreditation?

Worldwide demand for reliable, safe products and services makes accreditation a necessity. Accreditation from a globally respected agency like IAS means immediate acceptance and assures confidence in your service or product. The best way to demonstrate the highest level of service and good value is through accreditation. Choosing the right organization to evaluate and accredit your professional services has direct impact on your success.

Accreditation is essential if you are involved in any profession that has a direct impact on public safety and welfare. International Accreditation Service welcomes the opportunity to partner with you and help you achieve and maintain your accreditation.
