Accreditation is granted to the Organization for the production of certified reference material
and reference material as follows:
1. Per APLAC TC008 sections 6.5 & 6.6 “For CRMs, the scope of accreditation shall be expressed in terms of
a best Reference Value Capability which shall include the RMP‟s estimate of its least uncertainty of
measurement (UCRM) for each property value’s range it reports. … CRMs that are an identification value
(such as species identification) or where the property value is an ordinal number (such as a color fastness
chart) do not require an uncertainty of measurement to be stated in the scope of accreditation.” Per section
6.3 “An accredited RMP is not permitted to report on a RM certificate an uncertainty of property value
which is less than or better than that stated in its scope of accreditation.” Per section 6.12 “The uncertainty
covered by the Reference Value Capability shall be expressed as the expanded uncertainty having a specific
coverage probability (often 95 %). The unit of the uncertainty shall always be the same as that of the
property value or in a term relative to the property value, for example a percentage or ratio of the property
value.” See sections 6.7 through 6.11 for additional information.
