*Our accreditation is limited to those activities described on our UKAS schedule of accreditation which is available on the link below.
Decision Rule: Unless otherwise requested YPG shall issue a Conformity Statement which will be based on a binary Decision Rule (“simple acceptance” of pass/fail) where the acceptance zone is the same size as the tolerance stated in the relevant standard being used as the basis of test, and a calibration uncertainty which is not greater than the tolerance. The reported expanded uncertainty is based on a standard uncertainty multiplied by a coverage factor k = 2, providing a level of confidence of approximately 95%. The uncertainty evaluation has been carried out in accordance with UKAS requirements.
The United Kingdom Accreditation Service (UKAS) is the national accreditation body for the United Kingdom, appointed by government, to assess organisations that provide certification, testing, inspection and calibration services.
