by Brianna Crandall — October 15, 2010—ASTM International has released new, revised or proposed standards in recent weeks on using bamboo in lumber products, various aspects of concrete, fire hazards in oxygen systems, and three-dimensional laser scanning technology.
A proposed revision to ASTM International standard ASTM D5456, Specification for Evaluation of Structural Composite Lumber Products, would add bamboo as a fiber material that can be used in the manufacture of engineered wood composite products. The standard specifies evaluation procedures for structural design properties that would allow the products to be used as substitutes for solid-sawn lumber and glue-laminated timbers in residential and commercial building construction.
New standard ASTM F2659, Guide for Preliminary Evaluation of Comparative Moisture Condition of Concrete, Gypsum Concrete and Other Floor Slabs and Screeds Using a Non-Destructive Electronic Moisture Meter qualifies the types of non-destructive moisture meter suitable for determining moisture levels in concrete, gypsum concrete and other types of floor slabs and provides guidelines for how, where and when such moisture meters are used and what limitations exist.
The revised ASTM Standards for Ready-Mixed Concrete: 4th Edition, includes 38 ASTM standards, the Metric Practice Guide of Concrete and Concrete Aggregates, and the Manual of Aggregate and Concrete Testing. It represents the latest information in the industry and is a valuable resource for specifiers, engineers, architects, contractors, builders, testing laboratories, concrete producers and students.
A new compilation of 23 ASTM standards, ASTM Standards for Fire Hazards in Oxygen Systems, addresses fire hazards in oxygen systems, including safe practices in design, materials selection, storage, handling and operations. The CD-ROM is a vital resource for those involved in the production or use of liquid or gaseous oxygen or oxygen-enriched gas mixtures, including engineers, scientists, technicians, purchasing agents, plant managers and operators, safety professionals, and those who supply, design or manufacture hardware for oxygen services. It is a companion CD to the ASTM Manual on Safe Use of Oxygen and Oxygen Systems: Handbook for Design, Operation, and Maintenance, 2nd Edition (Manual 36).
ASTM is developing new standards for three-dimensional laser scanning technology, including ASTM E2761, Specification for 3D Imaging Data Exchange. The working committee says a standardized data exchange format would provide users with greater flexibility in working with 3D point clouds than is currently possible, as well as lower costs and increase applications for 3D imaging, and help the design world in its current transition from 2D to 3D technology.
