Abstract

The National Physical Laboratory (NPL) and the United Kingdom Accreditation Service (UKAS) has organised a comparison in mass using stainless steel weights as transfer standards within the range 500 mg to 1 kg. Its purpose is to evaluate the equivalence of mass measurement of stainless steel weights in the UK for International Organisation of Legal Metrology (OIML) weight accuracy classes E1 to F2.
