CRRC Standards Development
Last page update: November 6, 2018
The current version of ANSI/CRRC S100 - Standard Test Methods for Determining Radiative Properties of Materials was approved by the American National Standards Institute on April 26, 2016.
The CRRC became an accredited standards developer for the American National Standards Institute (ANSI) in 2007. After a three-year process, the first edition of ANSI/CRRC S100 - Standard Test Methods for Determining Radiative Properties of Materials (formerly CRRC-1 Standard) was approved on November 16, 2010.
ANSI's Essential Requirements and CRRC's procedures specify that the process for standards development must be a collaborative, balanced, and consensus-based approval process. As such, every few years the standard must go through a public review process. As part of this process, consensus must be reached by representatives from materially-affected and interested parties. ANSI/CRRC S100 (2016) was developed with input from the public and the CRRC Consensus Body, a balanced group representing diverse interests, ensuring that all aspects of the standard are considered.
ANSI/CRRC S100 covers test specimen preparation and test methods for measuring the initial and aged radiative properties of roofing products. ANSI/CRRC S100 is referenced by building codes and rating programs worldwide in order to measure the initial and aged solar reflectance and thermal emittance of roofing products.

Frequently Asked Questions
What is ANSI/CRRC S100?
ANSI/CRRC S100 (formerly CRRC-1 Standard) was developed as a consensus-based standard to provide a consistent reference in energy and building codes regarding measuring the radiative performance of roofing performance. ANSI/CRRC S100 covers specimen preparation and test methods for measuring the initial and aged solar reflectance and thermal emittance of roofing products.
What is ANSI?
The American National Standards Institute (ANSI) is a distinguished non-profit organization that coordinates the development of voluntary consensus standards through its Essential Requirements, which require the process for standards development to be fair, open, and balanced.
How often is ANSI/CRRC S100 updated?
The CRRC updates ANSI/CRRC S100 approximately every three years. The primary reason for updating the standard is to incorporate changes made to the CRRC's Product Rating Program that are related to radiative properties measurement, including new test methods and practices adopted by the CRRC since the last update of ANSI/CRRC S100.
Where can I find a copy of the previous edition of the standard (CRRC-1 Standard 2012)?
You can download the archived standard here. CRRC-1 (2012) is superceded by ANSI/CRRC S100 (2016).
