2. An Interlaboratory Investigation of the Effect of Material Granularity and Sample Processing on
Measurement Variability: Nutritional Elements in Cereals
NIST Interagency/Internal Report (NISTIR)
Katrice A Lippa, Laura J Wood, Stefan D Leigh, Nathanael A Heckert
This interlaboratory study was uniquely designed to determine the effects of material granularity
and sample processing techniques on the measurement variability (i.e. precision) of nutritional
elements in various cereal materials. Participants w ...
3. Effects of fiber gripping methods on the single fiber tensile test:
I. Non parametric statistical analysis
Jae Hyun Kim, Nathanael A Heckert, Stefan D Leigh, Haruki Kobayashi, Walter G McDonough, Kirk D Rice, Gale Antrus Holmes
Single fiber tensile tests using two different gripping methods were carried out on various fiber lengths. One method (the glue-tab grip) consists of mounting a fiber onto a rigid tab as specified in ASTM C1557-03 using an adhesive, while the other ( ...
4. Breakfast Cereal Sampling Study for Nutritional Elements
Laura J Wood, Katrice A Lippa, Melissa Meaney Phillips, Catherine A Rimmer, Nathanael A Heckert, Stefan D Leigh, Amanda J Moors, Rebecca S Pugh
The National Institute of Standards and Technology (NIST) has established a Dietary Supplement Laboratory Quality Assurance Program (DSQAP) in collaboration with the National Institutes of Health Office of Dietary Supplements (NIH-ODS). The DSQAP de ...
5. Certification of NIST SRM 2569 Lead Paint Films for Children's Products
John L Molloy, John R Sieber, Karen E Murphy, Stephen E Long, Stefan D Leigh
SRM 2569 Lead Paint Films for Children‰s Products is a new Standard Reference Material (SRM) developed for use primarily with XRF instrumentation. It consists of three paint coatings, with nominally 0 mg/kg, 90 mg/kg, and 300 mg/kg of Pb added, on p ...
6. On the Relationship Between Deformation-Induced Surface Roughness and Plastic Strain in AA5052, Is it Really Linear?
Mark R Stoudt, Joseph Bunton Hubbard, Stefan D Leigh
Three different heat treatments of aluminum alloy AA5052 were subjected to various levels of uniaxial plastic strain. The resulting surface topographies were then evaluated using scanning laser confocal microscopy (SLCM) and stylus profilometry. St ...
7. SRM 1450d, Fibrous-Glass Board, for Thermal Conductivity from 280 K to 340 K
Special Publication (NIST SP)
Robert R Zarr, Amanda C. Harris, John F Roller, Stefan D Leigh
Thermal conductivity measurements at and near room temperature are presented as the basis for certified values of thermal conductivity for SRM 1450d, Fibrous Glass Board. The measurements have been conducted in accordance with a randomized full fact ...
8. Statistical analysis of fiber gripping effects on Kolsky bar test
Jae Hyun Kim, Nathanael A Heckert, Stefan D Leigh, Haruki Kobayashi, Walter G McDonough, Richard L. Rhorer, Kirk D Rice, Gale Antrus Holmes
Preliminary data for testing fibers at high strain rates using the Kolsky bar test by Ming Cheng et al. 1 indicated minimal effect of strain rate on the tensile stress-strain behavior of PPTA, poly (p-phenylene terephathalamide) fibers. In a differen ...
9. Statistical analysis of fiber gripping effects on single fiber tensile test
Jae Hyun Kim, Nathanael A Heckert, Stefan D Leigh, Walter G McDonough, Haruki Kobayashi, Kirk D Rice, Gale Antrus Holmes
10. Elemental Analysis of a Single-Walled Carbon Nanotube Candidate Reference Material
Rolf Louis Zeisler, Rick L. Paul, Rabia Oflaz, Lee Lijian Yu, Jacqueline L Mann, William R. Kelly, Brian E Lang, Stefan D Leigh, Jeffrey A Fagan
A material containing single-walled carbon nanotubes (SWCNTs) together with other carbon species, cata-lyst residues, and trace element contaminants has been prepared by the National Institute of Standards and Technology for characterization and dist ...
