Since the late 1970s, precast box sections have become an important component in the construction of culverts, storm drains and sewers, but there has not been a comprehensive standard for the installation of such sections. A new ASTM International standard fills this gap. ASTM C1675, Practice for Installation of Precast Reinforced Concrete Monolithic Box Sections for Culverts, Storm Drains and…, Technical Contact:, Roman Selig, Hamilton Kent LLC, Birmingham, Ala., Phone: 205-910-0690; roman.selig@hamiltonkent.com, ASTM Staff Contact:, Diane Trinsey, Phone: 610-832-9661; dtrinsey@astm.org, ASTM PR Contact:, Barbara Schindler, Phone: 610-832-9603; bschindl@astm.org R elease #9243

During the past five years, certain insulating oils have been found to contain corrosive sulfur that can produce copper sulfide deposits as a function of time and temperature in operating equipment. A proposed revision to ASTM standard D 1275, Test Method for Corrosive Sulfur in Electrical Insulating Oils, will provide a means to certify that new or in service oils either contain or do not…
