ASTM E3251-20 - Standard Test Method for Microbial Ingress Testing on Single-Use Systems
May 1, 2020 - ASTM International

4.1 Single-use systems (SUSs) used for biopharmaceutical manufacturing must maintain sterility and product quality of the fluid inside. Such articles or systems should therefore be validated as providing an effective barrier against microbial ingress. The microbial barrier properties...

Object Discrimination and Optical Performance Of a Real-Time 2-5 µm Hyperspectral Imager
FLIR

Hyperspectral imaging in the 2-5 mm band has implications for applications in detection and discrimination of objects of interest. Real time instrumentation is particularly powerful as a tool for characterization and field measurement. A compact, real-time, refractive MWIR hyperspectral imaging...

ASTM D7928-17 - Standard Test Method for Particle-Size Distribution (Gradation) of Fine-Grained Soils Using the Sedimentation (Hydrometer) Analysis
May 1, 2017 - ASTM International

1.1 This test method covers the quantitative determination of the distribution of particle sizes of the fine-grained portion of soils. The sedimentation or hydrometer method is used to determine the particle-size distribution (gradation) of the material that is finer than the No. 200 (75-µm)...

The Precision (and Promise) of the James Webb Space Telescope
April 2, 2015 - IEEE GlobalSpec

The James Webb Space Telescope (JWST) is a large space-based observatory scheduled for launch in October 2018. Originally called the Next Generation Space Telescope (NGST), it was renamed in 2002 in honor of James E. Webb, second administer of the U.S. space agency, NASA. The telescope is...

ASTM C1773-17 - Standard Test Method for Monotonic Axial Tensile Behavior of Continuous Fiber-Reinforced Advanced Ceramic Tubular Test Specimens at Ambient Temperature
February 1, 2017 - ASTM International

1.1 This test method determines the axial tensile strength and stress-strain response of continuous fiber-reinforced advanced ceramic composite tubes at ambient temperature under monotonic loading. This test method is specific to tube geometries, because fiber architecture and specimen geometry...

ASTM D7596-14 - Standard Test Method for Automatic Particle Counting and Particle Shape Classification of Oils Using a Direct Imaging Integrated Tester
June 1, 2014 - ASTM International

5.1 This test method is intended for use in analytical laboratories including on-site in-service oil analysis laboratories. Periodic sampling and analysis of lubricants have long been used as a means to determine overall machinery health. Atomic emission spectroscopy (AES) is often...

ASTM D7928-16 - Standard Test Method for Particle-Size Distribution (Gradation) of Fine-Grained Soils Using the Sedimentation (Hydrometer) Analysis
May 1, 2016 - ASTM International

1.1 This test method covers the quantitative determination of the distribution of particle sizes of the fine-grained portion of soils. The sedimentation or hydrometer method is used to determine the particle-size distribution (gradation) of the material that is finer than the No. 200 (75-µm)...

Thermography Enhances the Capabilities of Laser Transmission Welding (.pdf)
FLIR

In order to investigate the weldability of plastics, a thermographic system based on an FPA detector at 7.5 to 13 µm is realized. Using this technique, the influence of different material modifications and laser irradiation parameters on the heating behavior of selected thermoplastics is...
