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…

X-ray diffraction has become a popular means of residual stress measurement in the aerospace materials field over the last 50 years. A proposed new guide being developed by ASTM International Committee E28 on Mechanical Testing will provide the necessary information to obtain the most reliable residual stress values as well as identify and evaluate potential errors in measurement, paving the way…

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…

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…
