Historical Standard: ASTM D4802-02 Standard Specification for Poly(Methyl Methacrylate) Acrylic Plastic Sheet
SUPERSEDED (see Active link, below)
ASTM D4802
1. Scope
1.1 This specification covers monolithic methacrylate sheets produced by various processes. For this specification, methacrylate sheet shall be composed of polymerized acrylic monomers of which at least 80 % shall be methyl methacrylate.
Note 1This specification is intended to consolidate the requirements of the Cast Methacrylate Plastic Sheets portion of discontinued Fed. Spec. L-P-391D, discontinued Specification D 702, Cast Methacrylate Plastic Sheets, Rods, Tubes and Shapes, and discontinued Specification D 1547, Extruded Acrylic Plastic Sheet.
1.2 This specification is intended to cover acrylic sheet for general-purpose applications. For specialty applications consult the appropriate use standards.
1.3 The following safety hazards caveat pertains only to the test methods portion, Section 8, of this specification: 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.
1.4 Acrylic sheet is used frequently in applications in which extreme clarity, lack of optical distortion and absence of any foreign particulate matter are of primary significance. Reground material may be used as long as careful control is used to eliminate adverse effects on these properties. The use of recycled material in type B-1 and B-2 sheet, may have adverse effects on these properties which would preclude its use in most cases. The use of recycled or reground material is not possible for type A-1 and A-2 materials since the sheet is produced directly from monomer
Note 2This standard is similar to ISO 7823-1:1987 (E) in title only. The technical content is significantly different.
