Three certified reference materials, including sediment (IAEA-410) and seaweeds (IAEA-446, and NIST-SRM-4359) (Outola et al. 2006; Pham et 

The certified mass fractions delivered by Standard Reference Material (SRM) 1270a are intended primarily for use in validation of chemical and instrumental methods of analysis for element contents of iron and steel alloys. They can be used to validate value assignment of a laboratory's in-house reference materials.

Certified reference materials (CRMs) are 'controls' or standards used to check the quality and metrological traceability of products, to validate analytical measurement methods, or for the

MIFAB’s copper piston operated water hammer arrestors are lead free and certified to ASSE 1010-1996 and ANSI A112.26.1M Standards, as well as IAPMO and IAPMO R&T certified. The non-freeze wall hydrant is certified lead free by the UPC authority. As standards change, it is important for us to be able to exceed those standards and provide our
