  • Understanding an ASTM D 2000 Call Out (.pdf)
    An ASTM D 2000 "call out" may look like a chaotic alphanumeric code, but it can. be simplified and broken down into manageable pieces. At the basic level, ASTM D. 2000 identifies rubber products based on their resistance to heat ageing and resistance. to swelling in oil. In addition, the "call out
  • 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
  • History Of Nist Rockwell Test Block Standards
    In 1991, NIST began the development of a national Rockwell hardness standardization laboratory at the urging of the ASTM and U.S. industry. The goals of this program are to standardize the Rockwell hardness scales for the United States and to provide industry with stable national transfer standards
  • 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
  • Resistance of Unfilled Engineering Polymers to Prolonged Hot Water Exposure (.pdf)
    . 4) RADEL (R) R-5000 polyphenylsulfone (PPSU). 5) Polyetherimide (PEI). ASTM test specimens made for each resin were aged in 60°C (140°F) and 90°C (194°F) water for up to 16,000 hours. Periodic mechanical testing was conducted.
  • Medical Device Link .
    standards has been based on ISO document 11607, "Packaging for Terminally Sterilized Medical Devices. " Since FDA recognized ISO 11607 as a consensus standard, the ASTM F02.60 subcommittee on medical device packaging is submitting versions of the test methods cited in the ISO document for recognition
  • Designing With Plastics
    . Paying more per pound or per cubic inch is often more economical if less material can do the job. There is an attractive simplicity in deciding on the material with the highest ASTM test values as listed in manufacturers' data sheets. Unfortunately, this method seldom results in the best choice
  • An Investigation of Pin Bearing Strength on Composite Materials
    This paper aims to demonstrate the influence of various pin hole details and pin types to the. ultimate and 4% hole elongation bearing strength values. This paper will demonstrate that the. ASTM D 953 bearing strength test can be very misleading and that actual connection details. should
  • Fluoroelastomers and Modern Engine Fluids
    Two classes of fluoroelastomers, FKM and FEPM, are aged at 150°C in dry heat, ASTM reference. engine oil and an organic acid based engine coolant. The test procedure, which uses unique component geometry, test jig and test vessel concept appears to offer a rapid (168 hours), reproducible measure
  • A better way to fix bones
    for tooling and instrument applications. Recent tests on a new, essentially nickel-free stainless alloy, BioDur 108 (ASTM F2229-02), have shown it is significantly stronger, in both annealed and cold-worked conditions, than any of the nickel stainless alloys currently serving in biomedical implants
  • Medical Device Link .
    ASTM International Committee F02, Flexible Barrier Packaging, completed balloting for a test method in June 2007. The test is used to rank porous packaging materials in sterile applications by their ability to hold out bacteria. The result of this balloting was test method ASTM F2638-07, Standard
  • Prediction of Polyolefin Foamability
    Many different polyolefinic foams and effectively nonfoamable polyolefinic resins were studied by ASTM. D-4440, "Standard Test Method for Plastics: Dynamic Mechanical Properties Melt Rheology" techniques [1]. The sensitivity of this test method to chain branching of the polymeric molecule
