1. An Interlaboratory Investigation of the Effect of Material Granularity and Sample Processing on Measurement Variability: Nutritional Elements in Cereals
Series: NIST Interagency/Internal Report (NISTIR)
Report Number: 7927
Published: 5/9/2013
Authors: Katrice A Lippa, Laura J Wood, Stefan D Leigh, Nathanael A Heckert
Abstract: 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 ...

2. Effects of fiber gripping methods on the single fiber tensile test: I. Non parametric statistical analysis
Published: 2/15/2013
Authors: Jae Hyun Kim, Nathanael A Heckert, Stefan D Leigh, Haruki Kobayashi, Walter G McDonough, Kirk D Rice, Gale Antrus Holmes
Abstract: 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. Certification of NIST SRM 2569 Lead Paint Films for Children's Products
Published: 10/15/2012
Authors: John L Molloy, John R Sieber, Karen E Murphy, Stephen E Long, Stefan D Leigh
Abstract: 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 ...

5. On the Relationship Between Deformation-Induced Surface Roughness and Plastic Strain in AA5052— Is it Really Linear?
Published: 8/1/2011
Authors: Mark R Stoudt, Joseph Bunton Hubbard, Stefan D Leigh
Abstract: 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 ...

6. SRM 1450d, Fibrous-Glass Board, for Thermal Conductivity from 280 K to 340 K
Series: Special Publication (NIST SP)
Report Number: 260-173
Published: 8/1/2011
Authors: Robert R Zarr, Amanda C. Harris, John F Roller, Stefan D Leigh
Abstract: 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 ...

7. Statistical analysis of fiber gripping effects on Kolsky bar test
Published: 6/14/2011
Authors: Jae Hyun Kim, Nathanael A Heckert, Stefan D Leigh, Haruki Kobayashi, Walter G McDonough, Richard L. Rhorer, Kirk D Rice, Gale Antrus Holmes
Abstract: 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 ...
