Drainage failures are one of the major problems confronting owners and operators of synthetic turf sports fields. A proposed new standard that provides a test for vertical permeability of synthetic turf will be useful to designers, testing agencies and contractors in minimizing problems associated with field drainage. According to John J. Amato, JJA Sports and a member of ASTM Committee F08 on…

No industry standard currently exists that addresses the vacuum sealing requirements of knife-edged flanges for high vacuum applications. Existing international standards focus on interchangeability of the hardware, but do not address the reliability of the seal. ASTM International Committee E42 on Surface Analysis is now working on a proposed standard on the subject, WK21206 , Specification…

A 2002 workshop on galling wear held by ASTM International Committee G02 on Wear and Erosion provided the impetus for the development of a new standard, ASTM G196 , Test Method for Galling Resistance of Material Couples. The new standard is under the jurisdiction of Subcommittee G02.40 on Non-Abrasive Wear. According to Scott Hummel, Ph.D., associate professor, head of the department of…

New Advanced Ceramics Standards from ASTM Cover Fracture Mirror Size Analysis, Tensile Strength DataSubcommittee C28.01 on Mechanical Properties and Performance, part of ASTM International Committee C28 on Advanced Ceramics, has recently approved two new standards, ASTM C1678 , Practice for Fractographic Analysis of Fracture Mirror Sizes in Ceramics and Glasses, and ASTM C1683 , Practice for Size Scaling of Tensile Strengths Using Weibull Statistics for Advanced Ceramics., ASTM C1678 —Bringing Consistency to Fracture Mirror Size Analysis, Fracture mirror size analysis is a powerful quantitative tool for the interpretation of broken ceramic and glass articles. While this type of analysis can be used to determine the stress in a part at the instant of fracture, inspection and interpretation procedures have often varied, resulting in uncertainty in stress estimates. ASTM C1678, Practice for Fractographic Analysis of Fracture Mirror…, ASTM C1683 —Scaling Strength Values, ASTM C1683, Practice for Size Scaling of Tensile Strength Using Weibull Statistics for Advanced Ceramics, provides methodology to convert fracture strength parameters estimated from data obtained with one test geometry to strength parameters representing other test geometries. Stephen Duffy, chair of civil engineering, Cleveland State University, and C28 member, says that companies producing…

Protecting the eyes of athletes is the central purpose of ASTM International standard F 803 , Specification for Eye Protectors for Selected Sports. However, with an increasing number of sports requiring eye protection, Subcommittee F08.57 on Eye Safety for Sports has been developing individual standards covering eye protection for specific sports. The subcommittee, which is part of ASTM…
