A new ASTM International standard provides a more detailed and complete description of a test protocol that has been used for more than 40 years in code requirements and specifications for fire-retardant-treated wood. This test is now also used in some codes for building products that are not wood. The new standard, ASTM E2768 , Test Method for Extended Duration Surface Burning Characteristics of…

Consumers who are purchasing building materials for homes want to be assured that the materials are mold resistant. A proposed new ASTM standard will allow for a mold-resistance rating to be given to specific materials, depending on how the materials perform to the test method. The proposed new standard, ASTM WK32079 , Test Method for Determination of Mold Growth on Building Products Designed for…

Discussions concerning how easily test results for dimension stone test specimens can be influenced by improper or nonuniform preparation methods have led to the ongoing development of a proposed new ASTM International standard. The new standard, ASTM WK31179 , Practice for Selection and Preparation of Dimension Stone Test Specimens, is being developed by Subcommittee C18.08 on Selection of…

While standards for outdoor calibration techniques for solar radiometers exist, there are currently no general standards that deal with issues of indoor calibration transfers between radiometers of different design. A proposed new ASTM standard, ASTM WK27263, Test Method for Indoor Transfer of Calibration from Reference to Field Pyranometers, will address in detail issues associated with…

Petrography is routinely performed on dimension stone for many construction projects in which new stone is being used, and it is often required in technical specifications. In order to facilitate this process, ASTM International Committee C18 on Dimension Stone has developed a new standard, ASTM C1721 , Guide for Petrographic Examination of Dimension Stone. The new standard is under the…, ASTM Committee C18 Next Meeting:, April 21-22, April Committee Week, St. Louis, Mo., Technical Contact:, Michael Scheffler, Wiss, Janney, Elstner Associates Inc., Northbrook, Ill., Phone: 847-272-7400; mscheffler@wje.com, ASTM Staff Contact:, Jeff Adkins, Phone: 610-832-9738; jadkins@astm.org, ASTM PR Contact:, Barbara Schindler, Phone: 610-832-9603; bschindl@astm.org Release #8432/Dec2009

Flow characteristics of fine metal powders are important in filling dies for pressing of powder metallurgy compacts, which are later sintered and sometimes machined into finished parts. The flow rate, as measured by a new ASTM standard, determines the flow necessary for a precise quantity of powder to be introduced into the die. The new standard, B964 , Test Methods for Flow Rate of Metal Powders…
