Abstract The National Institute of Standards and Technology (NIST) certifies a suite of Standard Reference Materials (SRMs) to address specific aspects of the performance of X-ray powder diffraction instruments. This report describes SRM 1976b, the third generation of this powder diffraction SRM.

The SRMs were developed at the request of industry in a unique collaboration between NIST and the Joint Research Centre of the European Commission in Belgium. Standard Reference Materials 1992 and 1993 can help ensure the accuracy of measurements made with electrophoretic light scattering and electroacoustic instruments.

NIST traceable reference material (NTRM) means a calibration gas mixture tested by and certified by the National Institutes of Standards and Technologies (NIST) 

FOREWORD TheNationalInstituteofStandardsandTechnology(NIST),formerlytheNationalBureauof Standards,wasestablishedbytheU.S

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

The SRM is certified by NIST against primary gas standards which are prepared by NIST and which have undergone rigorous validation both at NIST and internationally. The SRM is then sold to users through the NIST's SRM Program. The NTRM program is a collaboration between NIST and a specialty gas company to certify a production lot of gas standards.
