In order for research methods to be consistent, accessible and reproducible, we need universal, widely understood standards for research that all scientists adhere to. NPL has been responsible for maintaining fundamental standards and units for more than 100 years and is now engaged in pioneering work to create a set of “gold standards” for all scientific methodologies, materials, analyses and protocols, based on exhaustive testing at a large number of laboratories, in tandem with both industry and national and international standardisation organisations.
