7.14.4 Remarks

The thickness of the sheet material and/or the (laminated or non-laminated) panel construction must ensure that distortion cannot be imposed through manual force.

Finished flat architectural panels may not deviate more than 0.75 % in flatness with respect to the longest side and diagonal of the article, and must meet the
requirements of the manufacturer with regard to sheet thickness, sheet quality, construction and technical design of the article. The inspection frequency for this
additional requirement during production is at least 1 x per month. Panels are measured in the position in which they will be installed.

The enamelled surface shall be visually examined either in natural light or in artificial daylight D 65 (see EN ISO 105-J03). The surface shall be examined from a
distance at which the fixed panel would normally be viewed. The enamelled surface shall be free from defects liable to change the general appearance of the
panel.

Resistance to graffiti: After eight days of ageing, inks, varnishes, lacquers or paints, shall be easily removable with suitable solvents without any visible gloss or colour change
in the enamel surface.
