Unless otherwise specified, the export controls for military, dual-use and strategic items contained in this Guide apply to all destinations except the United States. Terms in "quotations" are defined terms. In some instances chemicals are listed by name and CAS number. The list applies to chemicals of the same structural formula including hydrates regardless of name or CAS number.
CAS numbers are shown to assist in identifying a particular chemical or mixture, irrespective of nomenclature. CAS numbers cannot be used as unique identifiers because some forms of the listed chemical have different CAS numbers and mixtures containing a listed chemical may also have different CAS numbers. The export of "technology" which is "required" for the "development", "production" or "use" of items controlled in the Dual-Use List is controlled according to the provisions in each Category.
This "technology" remains under control even when applicable to any uncontrolled item. Controls do not apply to that "technology" which is the minimum necessary for the installation, operation, maintenance checking or repair of those items which are not controlled or whose export has been authorised. This does not release such "technology" controlled in entries Controls do not apply to "technology" in the "public domain", to "basic scientific research" or to the minimum necessary information for patent applications.

Wood is a porous and fibrous structural tissue found in the stems and roots of trees and other woody plants. It is an organic material - a natural composite of cellulose fibers that are strong in tension and embedded in a matrix of lignin that resists compression. Wood is sometimes defined as only the secondary xylem in the stems of trees,  or it is defined more broadly to include the same type of tissue elsewhere such as in the roots of trees or shrubs. It also conveys water and nutrients between the leaves , other growing tissues, and the roots. Wood may also refer to other plant materials with comparable properties, and to material engineered from wood, or wood chips or fiber. Wood has been used for thousands of years for fuel , as a construction material , for making tools and weapons , furniture and paper.

ASTM's textile standards provide the specifications and test methods for the physical, mechanical, and chemical properties of textiles, fabrics, and cloths, as well as the natural and artificial fibers that constitute them. The textiles covered by these standards are commonly formed by weaving, knitting, or spinning together fibers such as glass fiber strands, wool and other animal fibers, cotton and other plant-derived fibers, yarn, sewing threads, and mohair, to name a few. These textile standards help fabric and cloth designers and manufacturers in testing textiles to ensure acceptable characteristics towards proper end-use. Additive Manufacturing Standards.
