standard reference materials

Standard Reference Materials (SRMs) are carefully characterized substances or materials used to ensure the accuracy and reliability of measurements in laboratories. They have known properties, like composition or physical characteristics, which serve as benchmarks for testing and calibration. Scientists and industries use SRMs to validate their testing methods and instruments, ensuring that results are consistent and trustworthy. Think of SRMs as trusted yardsticks in scientific measurements—without them, it would be challenging to compare and trust the results across different laboratories or studies.
