What is the NIST established value for Standard Reference Material for lead?

The established value for the Standard Reference Material (SRM) for lead set by the National Institute of Standards and Technology (NIST) is indeed 1.02 mg/cm². This value serves as an important benchmark for laboratories that conduct lead testing and analysis. The SRM provides a consistent reference point that ensures accuracy and reliability in measuring lead content in various materials.

Using this specific value helps laboratories calibrate their equipment and validate their measurement processes, which is critical for regulatory compliance and public health safety. Accurate lead measurements are essential in environments where lead exposure could occur, such as in housing built before 1978, which is critical for inspectors dealing with potential lead hazards. Having a standardized material ensures that lead detection technologies and methodologies yield reliable results, which is especially important given the health implications associated with lead exposure.
