The National Institute of Standards and Technology (NIST) has developed the Semiconductor Low Flow Standard (SLowFlowS), a new rate-of-rise (RoR) gas flow standard capable of measuring flows as low as 0.01 standard cm³/min. SLowFlowS incorporates two
The most popular international test standards for Charpy testing, namely ASTM E23, ASTM A370, and ISO 148-1, prescribe significantly different tolerances for the specimen ligament length, ranging from ±0.025 mm (E23) to ±0.01 mm (A370). A study conducted

Standard Reference Material (SRM) 3672a Organic Contaminants in Smokers' Urine (Frozen) and SRM 3673a Organic Contaminants in Non-Smokers' Urine (Frozen) are intended for use in evaluating analytical methods for the determination of selected naturally
The 2023 Photopolymer Additive Manufacturing Alliance (PAMA) Workshop convened experts from academia, industry, and government to explore the state-of-the-art and future opportunities in photopolymer-based 3D printing. The workshop was organized around
We compare the outputs of two Satellite Time and Location (STL) low Earth orbit (LEO) receivers in common-view with a very long baseline. By comparing the STL pulse per second (PPS) output to national laboratory timescales at distant locations, we can

For users of the network time protocol (NTP), a "lucky packet" is defined as one which is returned back to the client with very short roundtrip travel time over the internet. In NTP the error budget of the time offset measurement is dominated by the
In FY 2024, of the 23 federal agencies that reported, four federal agencies added a combined total of six government unique standards (GUS) in lieu of voluntary consensus standards (VCS.) No other agency added or rescinded any GUS in lieu of VCS, leaving a
The latest protocols are described for the NIST assignment of fluorescence intensity to calibration spheres or beads, which are used primarily for the accurate measurement of particle intensity in quantitative flow cytometry. Procedures for measuring
