The Elcometer 4695 Display Charts / Spreading Rate are Leneta test charts used in coatings laboratories to assess film opacity and hiding power by drawdown or brushout. Made from naturally bright, non-fluorescent white paper, they contain no optical brighteners that would otherwise skew instrumental colour measurements, which matters when a hiding or spreading-rate result has to be objective and repeatable.

The display charts use time-tested diagonally striped black and white patterns that emphasise variations in film opacity with strong visual impact, making them suited to hiding power display work. The Spreading Rate charts (Form 8H) are accurately 0.1 square metres in area (approximately one square foot) and are used in brushout hiding tests at specified spreading rates as described in ASTM Method D 344. The charts can be used with the Elcometer 4340 Motorised Film Applicator for consistent film application.

Two sizes are supplied: the 8B chart at 194 x 289mm (250 per box, four boxes per case) and the larger 8H chart at 286 x 438mm (125 per box, four boxes per case), available by box or case. They can be used in accordance with AS/NZS 1580.213.1, ASTM D 344, ASTM D2805, ASTM D 2486, ASTM D 5150, ASTM D 6441, BS 3900-D4, DIN 53162-2, FTMS 141 4121 and ISO 2814.
