NSF International

Food Safety

The NSF (National Sanitation Foundation) is the largest organization in the world in the realm of assessing and certifying the products and materials destined for contact with foodstuffs and their suitability for coming into contact with foodstuffs. The NSF mark, synonymous with public health, is recognized around the world as a symbol of the high standards of safety of all the products it certifies, meaning that customers can rest easy when purchasing anything with NSF certification.
Stone Italiana’s materials have been awarded the prestigious NSF/ANSI Std. 51 mark (National Sanitation Foundation - Food Equipment Materials), guaranteeing that they are safe for contact with foodstuffs. They fulfil the strict chemical analysis criteria for the certification, proving that the materials used to manufacture them meet international food safety requirements.
In the USA, suitability for contact with foodstuffs and the use of food additives are governed by chapter 21 of theCode of Federal Regulations, (CFR). This chapter is handled by the DA (Food and Drug Administration U.S.A.) which, by awarding the NSF 51 certification, guarantees that Stone Italiana surfaces are “food contact proof” and therefore suitable for use as kitchen worktops in contact with foodstuffs.
NSF 51 certification consists of:
  • Initial Type Testing (ITT) and periodical testing of samples of Stone Italiana materials at NSF laboratories in the USA;
  • Yearly spot inspections at the Stone Italiana production plant in order to assess the processes for receiving base materials, colourants, additives and resins, and to ensure the traceability of the batches of all the components declared in the formulations both at the mixing and the finishing stage.
