16、3 94 = 3404589 008624L IT2 Page 2 EN 2010 if the latter is judged to be nearer the imaginary contrast lying midway between two adjacent pairs than it is to either, the tested specimen is given an intermediate assessment, for example 4-5 or 23. A rating of 5 is given only when there is no perceived d
17、ifference be- tween the tested specimen and the original piece. If the Sstep scale is used, the degree of staining of the tested specimen is that number of the grey scale which has a perceived colour difference nearest in magnitude to the perceived colour difference be- tween the original piece and
18、the tested specimen. A rating of 5 is given only when there is no perceived difference between the tested specimen and the original piece. When a number of assessments have been made, it is very useful to compare all the pairs of original and tested specimens which have been given the same numerical
19、 rating. This gives a good indication of the consistency of the assessments, since any errors be come prominent. Pairs which do not appear to have the same degree of contrast as the remainder of their groups should be rechecked against the grey scale and, if necessary, the rating should be changed.
