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. 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.
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.

This fourth edition cancels and replaces the third edition ISO 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 is 1,5 mm to 25 mm.
For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document 7823- any amendments applies.

Revision of ISO Test conditions for moulding and extrusion plastics ISO Immersion method, liquid 78823-1 method and titration method ISO Density gradient column method ISO Rockwell hardness ISO Xenon-arc sources ISO Open-flame carbonarc lamps ISO Determination of coefficient of linear thermal expansion and glass transition temperature ISO Single-beam instrument ISO Double-beam instrument ISO Revision in parts of ISO National environmental legislation and regulations shall be followed regarding additives.
There shall be no scratches, marks or other surface defects larger than 3 mm2 each anywhere in the sheet. Each defect shall be considered separately. Table 1 — Classification of defects 5. What constitutes a significant number shall be agreed between the interested parties. Variations in colour shall be agreed upon between the interested parties.
For cut sheets, the tolerances for each sheet shall be as specified in Table 2. The tolerances apply within each sheet and from sheet to sheet. For measurements made under ambient conditions, due allowance shall be made for dimensional changes due to the differences in temperature and relative humidity between test locations. Examples of, and test methods for, such properties are presented in Table 4. The sampling procedure given in ISO is widely accepted and frequently used. Hence it is recommended.
When it is necessary to 7283-1 the sheet to the thickness required for a particular test method, one original surface shall isso left intact.
Measurements shall be carried out at not less than mm from the sheet edge. The original surface shall be put under tension whenever the specimen has been machined to the specified dimensions. The pendulum shall strike the surface that is opposite to the original one if the specimen has been machined to the specified dimensions.
Measurements shall not be carried out on isso with a thickness below 3 mm. Flammability The flammability and burning properties shall be determined in accordance with national fire regulations.
By agreement between the interested parties, the light transmittance may alternatively be determined oso exposure to a carbon-arc lamp see ISO Changes in colour and properties after exposure shall be determined in accordance with ISO The details of these tests shall be agreed upon between the interested parties. For the purposes of on-line quality control testing, this drying stage may be omitted, but in cases of dispute it is required.
Mark the four sides and measure the length of each to the nearest 0,02 mm. Take suitable precautions to avoid the specimens sticking to the plate: The heating time, which depends on the thickness of the sheet, shall be as given in Table A.
Then sprinkle a light covering of talc isl the specimen, place a second aluminium sheet over the specimen jso spacer, and fasten the two aluminium sheets together lightly with clips. Calculate the average percentage change for the four sides of each specimen and the average value for the set of three specimens.
