  • Standard of Coulometric Film Oxygen Permeability Testing —— ASTM D 3985
    Abstract: Based on standard ASTM D 3985, this article briefs on coulometric oxygen permeability testing of film and sheet materials. It also presents a detailed introduction about the principal and operating procedure of coulometric testing. With the accelerated development of trade globalization
  • Tension Testing of Metallic Materials (ASTM E8)
    ASTM E 8 describes tension testing methods to determine yield strength, yield point elongation, tensile strength, elongation and reduction of area of metal products. It applies to metallic materials in any form, including: sheet, plate, wire, rod, bar, pipe and tube. For each of these specimen
  • Standard Abbreviations for Rubbery Materials
    Based on ISO recommendation R1629 and ASTM D 1418
  • A Probabilistic Approach to Modeling Microstructural Variability and Fatigue Behavior in ASTM F562 Medical Grade Wire (.pdf)
    Several previous studies have demonstrated the importance of constituent inclusion particle distributions on variability in observed fatigue lifetimes. Such models have often concentrated on crack growth behavior in standard test specimens such as single edge notch tension (SENT) geometries
  • A New Code of Practice for Remote Field Testing (RFT)
    As world leaders in RFT (Remote Field Testing), R.T.Co. is spearheading the initiative to create codes of practice that will help improve the quality of RFT services industry-wide. A new ASTM standard practice for RFT-for which R.T.Co. were primary authors-is due out soon. Watch for some positive
  • Biodiesel filtration with MaxFlo case study Filter Press
    after 20 minutes circulation for TSS, soap, free glycerine and water tests. All parameters passed ASTM standard test specifications.
  • Measurement for Monotonic Equibiaxial Flexural Strength of Glass
    . In other words, surface strength could be called an indicator of the strength of the glass surface itself. In this article, we introduce an example of a ring bending test, as per the ASTM standard, to obtain the surface strength of glass.
  • Case Study # 5 - Alloy F75
    demonstrated that F75 components meet the chemical specifications and exceed the mechanical property specifications of the ASTM standard, F75-01 Standard Specification for Cobalt-28 Chromium-6 Molybdenum Alloy Castings and Casting Alloy for Surgical Implants (UNS R30075). Further, F75 properties
  • On-Site testing of Spray Applied Polyurethane Foam (SPF)
    Application of new and existing roofing systems consisting of spray applied polyurethane foam (SPF) should currently meet ASTM standards. These are either ASTM D 5469 for new systems or a proposed new standard from ASTM for coverings applied over existing roofing systems. These standards outline
  • Definitions and Explanations
    ASTM (American Society for Testing and Materials): A nonprofit industry wide organization that formulates test methods and material specifications, and publishes standards, testing methods, recommended practices, definitions, and other materials. AWG: Acronym for American Wire Gauge. Conductors
  • Epoxies Used in Tensile Testing: Film vs. Liquid-Why is There a Difference? (.pdf)
    Tensile testing of thermal spray coatings is currently covered by a variety of internal company specifications and generally by ASTM C-633. It is a highly recognized fact that liquid epoxies, on average, produce higher results in side by side comparisons with their film counterparts. However
