NIST supports accurate and compatible measurements by certifying and providing over 1200 Standard Reference Materials® with well-characterized composition or properties, or both. About NIST SRMs.

In the world of science and manufacturing, accuracy is paramount. One key player in ensuring this accuracy is the National Institute of Standards (NIST) and its Standard Reference Materials (SRMs), also known as NIST SRMs. The gold standard, NIST SRMs, are used to validate analytical methods and calibrate instruments.

NIST-traceable standards are reference materials certified to specific values laid out by the National Institute of Standards and Technology (NIST). They are designed specifically for standardized instrument calibration and quality assurance protocols aimed at eliminating measurement uncertainties.

How do you know if the numbers in your lab results or your food's nutritional labels are correct? Labs and manufacturers use Standard Reference Materials or SRMs to make sure that the machines measuring these numbers are accurate.
