ISO 7823-1:2003(E)
Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies
(ISO member bodies). The work of preparing International Standards is normally carried out through ISO
technical committees. Each member body interested in a subject for which a technical committee has been
established has the right to be represented on that committee. International organizations, governmental and
non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the
International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 7823-1 was prepared by Technical Committee ISO/TC 61, Plastics, Subcommittee SC 11, Products.
This fourth edition cancels and replaces the third edition (ISO 7823-1:1998), which has been technically
revised.
ISO 7823 consists of the following parts, under the general title Plastics — Poly(methyl methacrylate)
sheets ― Types, dimensions and characteristics:
 Part 1: Cast sheets
 Part 2: Extruded sheets
 Part 3: Continuous cast sheets

Part 1:
Cast sheets
1 Scope
This part of ISO 7823 specifies requirements for non-modified flat poly(methyl methacrylate) (PMMA) cast
sheets (plates) for general-purpose use. The sheets may be colourless or coloured, and may be transparent,
translucent or opaque.
The thickness range of the sheets covered by this part of ISO 7823 is 1,5 mm to 25 mm.
