Standard Specification for Cast Poly(Methyl Methacrylate) Plastic Rods, Tubes, and Shapes
ABSTRACT
This specification covers poly(methyl mathacrylate) plastic rods, tubes, and other shapes produced by casting or machining cast blanks. It does not however apply to heat-formed and molded or extruded parts and shapes, or sections that are made by assembling or joining two or more pieces. The plastics may be of two types according to the material's ultraviolet light absorbing properties while the castings may be specified according to the surface finishing which may be a smooth surface finish obtained either in the casting process or by surface polishing or a rough, unfinished surface which may be frosted, abraded, sanded, machined, or as-cast. Tests shall be conducted in the standard laboratory atmosphere to determine the physical and optical properties of the materials. The specimens shall conform to the index of refraction, specific gravity, water absorption, deflection temperature under flexural load, tensile strength, elongation at break, spectral transmittance, luminous transmittance, and haze requirements.
SCOPE
1.1 This specification covers poly(methyl methacrylate) rods, tubes, and other shapes produced by casting or machining cast blanks. This specification does not apply to heat-formed and molded or extruded parts and shapes, or sections that are made by assembling or joining two or more pieces. Note 1—The properties included in this specification are those required to identify the types and grades of materials covered. There may be other requirements necessary to identify particular characteristics.
1.2 The values stated in SI units are to be regarded as standard.
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. Note 2—There is no known ISO equivalent to this standard.

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.
