Abstract

This specification covers acrylic sheet material manufactured by the cell cast, continuous cast or melt (typically referred to as continuously manufactured sheet) process. <br>NOTE: Acrylic sheet material manufactured by continuous cast meets the requirements of material classified "Melt process category M-1" of ASTM D 4802. <br>Plastic sheet is of the following types, grades, and thicknesses as specified (see <a>6.2</a>, <a>tables I</a> and <a>III)</a>. </span><pre> Type RTPS-1 - Red transparent. Type RTPS-2 - Red transparent, smooth surface finish, one side; patterned pyramidal surface, second side. Type YTPS-1 - Yellow transparent. Type GTPS-1 - Green transparent. Type BTPS-1 - Blue transparent. Type BTPS-2 - Blue transparent, smooth surface finish, one-side; patterned pyramidal surface, second side.</pre> <br> <a><img alt="CHART" /></a> <pre> Type RTLS-1 - Red translucent. Type CLEAR-1 - Clear (colorless). Type CLEAR-2 - Clear (colorless), smooth surface finish, one side; patterned pyramidal surface, second side.</pre> <br> <strong>Beneficial comments (recommendations, additions, deletions) and any pertinent data which may be of use in improving this document should be addressed to: Commander, SEA 03R42, Naval Sea Systems Command, 2531 Jefferson Davis Hwy, Arlington, VA 22242-5160 by using the self-addressed Standardization Document Improvement Proposal (DD Form 1426) appearing at the end of this document or by letter.</strong> <br>White translucent sheet it of the type and grade specified in <a>table I</a> (see <a>6.2</a>). The thickness in <a>table I</a> is a requirement of the type and grade specified. <br><b><u>Intended Use:</u></b> The flat plastic sheet covered by this specification is intended for use in fabrication of window assemblies for lighting fixtures for Naval service. Reference to this specification on drawings or in product specifications may be made in order to specify the flat material to be used in the fabrication of a part. It should be clearly understood that the requirements apply to the flat material prior to forming or fabrication and not necessarily to the material in its final form. <br>
