The group applies these techniques to certification of gas standards in support of industries responding to U.S. and state regulations, environmental concerns, fairness in trade issues, and global climate change. The primary concern is to provide the infrastructure for high-quality, traceable gas measurements, allowing better decision-making by industry, regulators, government officials, research scientists, and the public. Measurement services are provided through the development of reference materials including NIST Traceable Reference Materials (NTRMs), Reference Materials (RMs), Standard Reference Materials (SRMs).
