Gas Concentration Standards Supporting Atmospheric Monitoring

Ongoing
NIST develops suites of SI-traceable, amount-of-substance, primary gas standard mixtures (PSMs) for key trace and greenhouse gas species to provide traceability to the International System of Units for a range of user communities. Standard Reference Materials (SRMs), certified to the PSMs, are

Hardness Standardization and Measurements

Ongoing
DESCRIPTION Purpose: Provide measurement traceability for the Knoop, Rockwell, and Vickers hardness scales and for coating thickness measurements that are based on magnetic methods. Goals: Harmonization of hardness and coating thickness testing protocols, in pursuit of reduction of measurement

Hierarchical Materials

Ongoing
The STG develops the methods and metrology that will lead to the understanding of the structure-property relationships of hierarchical composites in real medical PPE or protective applications, which heretofore has been lacking. This work establishes in situ monitoring of advanced manufacturing

Infrastructure for Agile Manufacturing Data Standards

Completed
Objective - T o develop and deploy to industry advances in standards and measurement science for model-based messaging standards and service-modeling methodology to enable manufacturers to improve the agility of manufacturing systems and manufacturing systems integration. What is the technical idea

Materials Testing in Hydrogen Gas

Ongoing
Hydrogen is known to have a deleterious effect on steels and other metals, but steels are the most cost-effective and commonly used materials for pipelines and pressure vessels. We are collaborating with the code bodies (ASME B31.12 and ISO 11114-4), DOT, and DOE, to enable the implementation of

Measurement Quality in Hydrogen Storage R&D

Ongoing
The hydrogen storage project targets metrologies that assess kinetics and energetics of hydrogen charging and discharging in combinatorial structures as well as the degradation mechanisms that limit life of use. New capabilities are being developed and several existing measurement capabilities are

Measurements for Hydrogen Storage Materials

Completed
The evaluation of candidate storage materials is complicated by a lack of readily available methods for the direct measurement of hydrogen content. MML is working together with researchers from NCNR, and PML to provide measurement tools to fill this gap. Prompt Gamma Activation Analysis (PGAA) is a

Membranes for Clean Water

Completed
Impact Access to affordable, clean water is vital to the nation's economic growth and security. Polymer-based membrane separation technologies based on reverse osmosis, forward osmosis and nanofiltration will play an increasingly critical role in the production of clean, safe water. In order to

Microsystems for Harsh Environment Testing

Completed
Classically, measurement of the mechanical properties and reliability of bulk-scale materials is performed with macroscopic specimens and methods. Specimen preparation limitations, miniaturized load-frame tooling problems, and inadequate understanding of the roles of specimen size and constraint on

Model-based Manufacturing Capability Definition

Completed
Objective - The Model-Based Manufacturing Capability Definition project will develop and deploy advances in standards and measurement science to enable manufacturers to define, measure, and control the capability of smart manufacturing systems. What is the new technical idea? Decisions across the

Multiscale structure and dynamics in advanced technological materials

Ongoing
New technologies increasingly harness materials phenomena that operate across many length-scales: e.g., in selective gas adsorption, additive manufacturing, new alloy designs, or advanced concretes. To overcome technology barriers, it is no longer sufficient just to characterize the materials

New Gas Standard Reference Materials to Support the Automotive Industry

Completed
NIST currently supports AIGER members by maintaining reasonable inventories of required gas SRMs that consist of dilute mixtures of key pollutants such as carbon dioxide, carbon monoxide, hydrocarbons, and nitric oxide. Newer vehicles produce lower levels of these pollutants because their engines

NIST Automated Vehicles Program

Ongoing
Measurement science and standards are needed to support the safe and predictable operation of future automated vehicles (AVs), which have great potential to significantly impact our daily lives and improve the competitiveness of our economy. A FY22 NIST Strategic and Emerging Research Initiatives

NIST Proficiency Testing

Ongoing
A typical lot of NIST SRMs has 300 units, with 5 specimens in each unit. These SRMs are tested by customers and the customer verification data is returned to NIST for evaluation according to the requirements of ASTM E23. Once a minimum of 50 verification results are returned to NIST for a particular

Per- and Polyfluoroalkyl Substances (PFAS)

Ongoing
Perfluorinated and polyfluorinated alkyl substances (PFAS) constitute a family of compounds that are distinguished by partial or complete fluorination of alkyl hydrocarbons. Dubbed “forever chemicals”, the unique chemistry of PFAS imparts a high level of stability, making the compounds resistant to

Physical Infrastructure: Connections

Completed
The NIST Physical Infrastructure Program will provide the critical measurement science needed to assess the condition of aging physical infrastructure and guide cost-effective strategies for its maintenance, repair, and replacement. Infrastructure management challenges in the U.S. have received

Pipeline Safety

Ongoing
The U.S. operates more than 2.5M miles of natural gas, petroleum and hazardous liquid pipelines, crossing all 50 states and operated by more than 3,000 companies. Fluid hydrocarbon fossil fuels remain the world leading source of energy. The safest and most reliable means of transporting these fuels
