Current methods for determining bulk specific gravity of aggregate are often time-consuming and not ideal for quality control checks during construction. However, a new ASTM International standard provides a fast method for determining the consistency of aggregate properties that are used in asphalt and concrete mixtures. Committee D04 on Road and Paving Materials has approved ASTM D7370…

Accepted Fire Prevention Measure to Benefit Citizen Safety Seeking to prevent accidental death and damage to property related to untended cigarettes, Finland has proposed that all cigarettes sold in the country be tested to assess their likelihood to cause fire in bedding or upholstered furniture. The regulatory proposal specifies the use of ASTM E2187 - an international standard developed by…

A growing need to recycle millions of tires discarded annually is the impetus for the continued development of a proposed new ASTM International specification that provides standards for converting tires into an asphalt product. WK20240 , Specification for Performance Graded Tire Rubber-Modified Asphalt Binder is being developed by Subcommittee D04.40 on Asphalt Specifications, under the…

A new Pennsylvania law to help prevent smoking-related fires will require that cigarettes sold in the state perform well when tested using ASTM International standard E2187 , Test Method for Measuring the Ignition Strength of Cigarettes. "Careless smoking is one of the leading causes of fires, killing hundreds and injuring thousands every year," said Rep. Tim Solobay, a volunteer firefighter who…

A proposed new ASTM International standard, WK16997 Test Method for Determining the Heat Release of Materials of Low Combustibility Using a Bench Scale Oxygen Consumption Calorimeter, will be used as a fire response test for products and materials that are difficult to ignite and have relatively low rates of heat release. The proposed standard is being developed by Subcommittee E05.23 on…

A new ruling by the Federal Railroad Administration cites an ASTM standard as a means of making emergency exits from trains more visible to emergency personnel. The standard cited, D 4956 , Specification for Retroreflective Sheeting for Traffic Control, is under the jurisdiction of Subcommittee D04.38 on Highway Traffic Control Materials, part of ASTM International Committee D04 on Road and…

A proposed new standard currently being developed by ASTM International Committee E05 on Fire Standards will establish a test protocol for assessing fire performance of decks and other horizontal exterior structures where combustibles beneath the structure can ignite. The proposed standard, WK17025 , Test Method for Evaluating the Under-Deck Fire Test Response of Deck Structures, is under the…

A proposed new standard will provide a practice for inspecting and evaluating the retroreflective properties of longitudinal non-intersection pavement markings. The proposed standard, WK16773 , Practice for Evaluating Retroreflectance of Pavement Markings Using Portable Hand-Operated Instruments, is being developed by Subcommittee D04.38 on Highway Traffic Control Materials, which is part of ASTM…

A new ASTM International standard will be used to quantify the uncertainty associated with measurements in fire tests in a consistent manner, while a proposed new E05 standard, WK14401 , Evaluating the Fire Test Response of Deck Structures to Burning Brands, will determine the fire test response of deck structures. , ASTM E 2536, Guide for Assessment of Measurement Uncertainty in Fire Tests, “Users of fire test data often need a quantitative indication of the quality of the data presented in a test report,” says Marc Janssens, director of the fire technology department at Southwest Research Institute and first vice chairman of Committee E05 . “This quantitative indication is referred to as the measurement uncertainty.” E 2536 will be used to quantify the uncertainty associated…, ASTM WK14401, Evaluating the Fire Test Response of Deck Structures to Burning Brands, Subcommittee E05.22 on Surface Burning is developing a proposed new standard, WK14401 , that will determine the fire test response of decks or other horizontal ancillary structures attached to or in close proximity to primary structures. While E05.22 member Paul Hough says that the task group working on WK14401 is already well-represented by manufacturers, regulators, wildland fire experts and…
