Annotation of standard text ASTM D4802-16 :
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. Materials shall be classified under categories and finishes: Category A-1; Category A-2; Category B-1; and Category B-2.Finish 1; Finish 2; Finish 3; Type UVF; and Type UVT. Tests shall be performed to determine the properties of the material in accordance with following test methods: test conditions; index of refraction; specific gravity; luminous transmittance; haze; water-absorption; shrinkage; thermal stability; deflection temperature under flexural load; tensile strength and elongation at break; impact strength; spectral transmittance of Type UVF and UVT sheet; abrasion resistance; coating adhesion; and chemical resistance.

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 1: This specification is intended to consolidate the
requirements of the Cast Methacrylate Plastic Sheets portion of

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: 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 is suitable for use 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, is not suitable for use when these properties are adversely affected. 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 2: This standard and ISO 7823-1 address the same subject
matter, but differ in technical content.
