Application
SRM1247 is intended for use in validating chemical and instrumental analysismethods. It is also suitable for validating the value assignment of in-housereference materials.
Features and Benefits
Information mass fraction values for constituents are provided and expressed as Mass Fraction (mg/kg).
Expiration details, and use instructions are provided on the NIST certificate.
The mass fraction values for elements in nickel-base alloys are provided and estimated using a Gaussian random effects model and the DerSimonian-Laird procedure. These values are metrologically traceable to the SI derived unit for mass fraction, expressed as milligrams per kilogram.
General description
Standard reference material Incoloy® 825 is a high-temperature alloy in wrought form. Each unit of SRM 1247 contains a single disk measuring around 35 mm in diameter and 19 mm in thickness. For more information, please refer to the COA and SDS.
