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.

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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. Note 2:?There is no known ISO equivalent to this
standard.
1.4?This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee. |
