Six months after the spring 2008 publication of ASTM standard E2600 , Practice for Assessment of Vapor Intrusion into Structures on Property Involved in Real Estate Transactions, the task group that developed it surveyed users to receive feedback on the new standard. According to Anthony Buonicore, CEO of the Buonicore Group and chair of the vapor intrusion task group, the survey results have led…

Subjects Include Vented Construction Systems, Furnace Exposure and Tunnel Fire Resistance, Subcommittee E05.11 on Fire Resistance, part of ASTM International Committee E05 on Fire Standards, is currently developing a number of proposed standards, including the following three test methods on vented construction systems, furnace exposure on test samples and tunnel fire resistance. All parties interested in working on fire resistance standards are encouraged to join in the activities of…, Vented Construction, Understanding how construction systems will perform in the earliest moments of a fire is crucial. A proposed new ASTM standard, WK22660 , Test Method for Evaluating Fire Performance of Vented Construction, will provide tests for evidence on how vented construction systems are affected by the first five minutes of a fire and will be used to complement existing fire testing methods test results “…, Furnace Exposure, Fire test laboratories and fire protection engineers will be the primary users of proposed new standard ASTM WK23795 , Test Method for Measuring the Uniformity of Furnace Exposure on Test Samples. The proposed standard provides general principles for measuring the uniformity of furnace exposure on samples tested in accordance with the following standards: - ASTM E119 , Test Methods for Fire…, Tunnel Fire Resistance, Fires in tunnels can reach temperatures as high as 2,500°F [1371°C], but current standards that deal with building fires provide for a maximum temperature of 2,000°F [1093°C] and are not specific to tunnels. A proposed new standard, ASTM WK23821 , Test Methods for Tunnel Fire Resistance, will be developed with the special considerations of tunnel fires in mind. According to Barry Badders, manager…

The U.S. Environmental Protection Agency has determined that the 2008 revision to an ASTM International standard describing the environmental assessment needs of parties involved in the acquisition of forestland and rural properties is now compliant with the agency’s All Appropriate Inquiries Rule (40 CFR Part 312, Standards and Practices for All Appropriate Inquires). The EPA decision came in a…

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…

Ceramic and glass companies, as well as universities and government laboratories, will be the primary users of a new ASTM standard that allows for the flexural strength determination of components made in a round shape or after finish machining with minimal waste. The standard, ASTM C1684 , Test Method for Flexural Strength of Advanced Ceramics at Ambient Temperature-Cylindrical Rod Strength, was…

Vapor intrusion from contaminated soil and groundwater into structures can potentially create significant liability and have a material impact on property value. Because of this, accurately determining whether a property has vapor intrusion issues is a concern for property owners, prospective purchasers and environmental professionals conducting due diligence. ASTM International Committee E50 on…

Information on light nonaqueous-phase liquids and their impact on the environment has grown significantly in the last 20 years. This accumulation of knowledge means that different remediation strategies are now available for sites that contain these substances. In order to facilitate decision making, ASTM International Committee E50 on Environmental Assessment has developed a new standard, E 2531…
