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…

ASTM International Committee E53 on Property Management Systems has begun developing new standards to address the beginning of a challenging new era for asset managers – the era of lost laptops. Understanding how organizations reached this point – where entities are losing an increasing number of sensitive assets such as computers, some with sensitive information stored in the memory devices – is…

ASTM International Committee B08 on Metallic and Inorganic Coatings has recently approved a revision of one of its most important standards, B 633 , Specification for Electrodeposited Coatings of Zinc on Iron and Steel. B 633 is under the jurisdiction of Task Group B08.08.04 on Soft Metals, which is part of Subcommittee B08.08 on Metallic Coatings. Zinc coatings are used to provide a sacrificial…

Asset budgets are often the third largest line item (after personnel and information technology) for many organizations. Because of this, asset managers in both the public and private sectors need to present compelling arguments and demonstrate strategic value to core missions in framing asset decisions. With this in mind, ASTM International Committee E53 on Property Management Systems has more…

ASTM International Committee C15 on Manufactured Masonry Units has created a new subcommittee, C15.11 on Adhered Manufactured Stone Masonry Veneer. The purpose of C15.11 is to develop and maintain product specifications and installation guidelines for adhered manufactured stone masonry veneer. According to Brenda Harris, chair of the new subcommittee, adhered manufactured stone masonry veneer…

Anyone who has ever lost time searching for a set of keys that simply are not where they’re supposed to be will appreciate the larger-scale, though similar concept behind E 2499 , Standard Practice for Classification of Equipment Physical Location Information, a new standard developed by ASTM International Committee E 53 on Property Management Systems. The goal of the standard, which is under the…
