ILAC is an international cooperation of laboratory and
inspection accreditation bodies.

It provides a focus for:

developing and harmonising laboratory and inspection accreditation
practices;
promoting laboratory and inspection accreditation to industry, governments,
regulators and consumers;
assisting and supporting developing accreditation systems;
global recognition of laboratories and inspection facilities via the ILAC
Arrangement, thus facilitating
acceptance of test, inspection and calibration data accompanying goods
across national borders.
