... , located in Boulder, Colorado, "characterizes the properties and structures of industrially important fluids and materials." Its work "provides a diverse stakeholder community with innovative measurements and models and critically evaluated data, leading to improved processes and better products, as well as new and improved standards." 1 The ACMD is organized into the following five groups:  Fatigue and Fracture Group  Fluid Characterization Group  Nanoscale Reliability Group  Thermodynamics Research Center Group  Thermophysical Properties of Fluids Group The division chief and four of the five group leaders are new in their positions with the same group structure as in 2017, so it is presumed that the organization is in a state of flux. Many of the individual projects in these groups are organized for either historical or administrative convenience, in contrast with unifying technical or methodological themes based on the MML mission statement.

... Worldwide, there are only a handful of examples of new materials being designed computationally prior to being discovered experimentally in the laboratory. With more accurate thermophysical data, the ability to computationally design new materials prior to synthesizing the material in the laboratory will provide breakthrough methodologies in materials design and remove the empiricism that has ruled the past 100 years.

... The area of additive manufacturing is high profile, but the MML work, both within ACMD and in other divisions, appears disjointed and is not focused on the MML mission statement. A number of ACMD projects utilize the outstanding capabilities of NIST in making precision measurements, but the individual projects appear to be driven by client needs rather than fulfilling the MML mission.

... There are several favorable examples of programs driven by stakeholder needs, most notably the Charpy Impact Machine Verification Program and the Thermophysical Properties of Fluids. The Charpy Impact Machine Verification Program serves over 1,200 manufacturers and users worldwide, whose Charpy Testing Machines are being certified by the ACMD for compliance with ASTM and ISO standards, and is an excellent example of monitoring stakeholder use of outputs through SRMs.

... Over the past 15-20 years, NIST's MML has evolved from a Materials Science and Engineering focused research laboratory to become the nation's premier material measurement laboratory specializing in precision measurement methodologies and standards, supporting industry in the chemical, biological, and materials fields. ACMD has the same breadth of industries as does the larger MML, with an outstanding history of precision chemical, thermodynamic, and mechanical property measurements.
