For vertical resistance measurements: a flat plate 640 mm ± 10 mm square, 5 mm ± 1 mm
thick, made from insulating material with a vertical resistance greater than 1014 X shall be used�
For point-to-point and resistance to ground measurements: a flat plate 1 300 mm ± 10 mm by
600 mm ± 10 mm, 5 mm ± 1 mm thick, made from insulating material with a vertical resistance at
least one order of magnitude greater than the expected value or if the expected value is unknown,
greater than 1014 X shall be used�
For tiles smaller than the size required for testing, several tiles may be combined together,
cutting where necessary to achieve the required area� Support plates (see 5�4) may be required�
If so, they shall be attached to the tiles, and the edges of adjacent tiles joined according to the
manufacturer’s instructions or as otherwise agreed� If tiles are used to form the test specimen,
measurements shall include a test across a minimum of one joint� Groundable points shall
be attached to one or more tiles before application of the support plates, bearing in mind the
requirement for a minimum distance of 1 000 mm ± 50 mm between a groundable point and the
positions of measuring resistance to ground (see 9�4)�
