1.1.9 Precedence of Standards. The following are Y14 Standards that are basic engineering drawing standards: ASME Y14.1, Decimal Inch Drawing Sheet Size and Format ASME Y14.1M, Metric Drawing Sheet Size and Format ASME Y14.2, Line Conventions and Lettering ASME Y14.3, Multiview and Sectional View Drawings ASME Y14.5, Dimensioning and Tolerancing ASME Y14.24, Types and Applications of Engineering Drawings ASME Y14.34, Associated Lists ASME Y14.35M, Revision of Engineering Drawings and Associated Documents ASME Y14.36M, Surface Texture Symbols ASME Y14.38, Abbreviations and Acronyms for Use on Drawings and Related Documents ASME Y14.41, Digital Product Definition Data Practices ASME Y14.100, Engineering Drawing Practices All other ASME Y14 standards are considered spe- cialty types of standards and contain additional require- ments or make exceptions to the basic standards as required to support a process or type of drawing. 1.1.10 Unless Otherwise Specified (UOS). The phrase “unless otherwise specified” or UOS is used to indicate a default requirement. The phrase is used when the default is a generally applied requirement and the exception can be clarified by providing a reference to another document or requirement. 2 REFERENCES The following publications form a part of this Standard to the extent specified herein. A more recent revision may be used provided there is no conflict with the text of this Standard. In the event of a conflict betweenthe textofthis Standard andthe references cited herein, the text of this Standard shall take precedence.

3.24 Ply Stackup View ply stackup view: a view representing the ply level rela- tionship ofeach ply and other items within the laminate. 3.25 Ply Table ply table: a table annotating the plies and items that are applicable to a composite part. See Fig. 9-1. 3.26 Preform preform: an assembly of dry fabric and fibers that has beenprepared for one ofseveral different wetresin injec- tion processes. A preform may be stitched or stabilized in some other way to hold its shape. A commingled preform may contain thermoplastic fibers and may be consolidated by elevated temperature and pressure without resin injection. 3.27 Roving roving: a number of strands, tows, or ends collected into a parallel bundle with little or no twist. In spun yarn production, an intermediate state between sliver and yarn. 3.28 Sequence sequence: denotes a sub-bond configuration (grouping of plies) for design definition/clarity. It may also be used, when specified, to define the manufacturing pro- cess (i.e., to tie groups of plies to specific tooling or process methodologies). 3.29 Tool Side tool side: the surface of the item adjacent to the tool surface. 3.30 Tool Side View tool side view: a viewing direction looking through the part towards the tool surface. 3.31 Tow tow: an untwisted bundle of continuous filaments. Com- monly used in referringto man-made fibers, particularly carbon and graphite fibers, in the composites industry (MIL-HDBK-17).
