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…

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…
