The ongoing focus on sustainability in construction has contributed to greater interest in vegetative, or green, roof systems, in which traditional roofing material is replaced or supplemented with vegetation. A proposed new ASTM International standard will address an important aspect of designing this kind of roofing: determining the proper roofing and waterproofing membrane for a particular…

When fasteners penetrate roofing or waterproofing products as a planned part of installation, it is expected in some cases that the product will resist water migration at the point of penetration. A new ASTM International standard, D7349 , Test Method for Determining the Capability of Roofing and Waterproofing Materials to Seal Around Fasteners, addresses this situation. ASTM D7349 was developed…

Modified bitumen products have been in use since the mid-1970s, and represent a substantial percentage of the commercial asphalt roofs installed throughout North America. A new ASTM International standard addresses the use of cold process adhesives in modified bitumen roofing systems. ASTM D7379 , Test Methods for Strength of Modified Bitumen Sheet Material Laps Using Cold Process Adhesive, was…

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…
