The use of test conditions differing from those specified may give different results; this applies both to the absolute magnitude and to the relation between values of the ease of dispersion of various pigments. The subscript DH<sub>PE<\/sub> is therefore used to designate the value obtained as specified in this part of ISO 23900.<\/p>\n<h4>PDF Catalog<\/h4>\n<table border=\"1px\" class=\"des-table\">\n<tr>\n<th>PDF Pages<\/th>\n<th>PDF Title<\/th>\n<\/tr>\n<tr>\n<td><b>2<b><\/td>\n<td>undefined  <\/td>\n<\/tr>\n<tr>\n<td><b>4<b><\/td>\n<td>European foreword <br \/> Endorsement notice  <\/td>\n<\/tr>\n<tr>\n<td><b>6<b><\/td>\n<td>Foreword  <\/td>\n<\/tr>\n<tr>\n<td><b>7<b><\/td>\n<td>1\tScope <br \/> 2\tNormative references <br \/> 3\tTerms and definitions  <\/td>\n<\/tr>\n<tr>\n<td><b>8<b><\/td>\n<td>4\tPrinciple <br \/> 5\tMaterials <br \/> 5.1\tMaterials for method A <br \/> 5.1.1\tTest medium <br \/> 5.1.2\tTitanium dioxide pigment <br \/> 5.2\tMaterials for method B <br \/> 5.2.1\tTest medium <br \/> 5.2.2\tTitanium dioxide pigment <br \/> 6\tApparatus  <\/td>\n<\/tr>\n<tr>\n<td><b>9<b><\/td>\n<td>7\tSampling <br \/> 8\tProcedure <br \/> 8.1\tTesting of colouristic properties in white reduction <br \/> 8.1.1\tPreparation of the mixtures <br \/> 8.1.2\tTwo-roll milling  <\/td>\n<\/tr>\n<tr>\n<td><b>10<b><\/td>\n<td>8.1.3\tPressing <br \/> 8.1.4\tPhotometric measurement <br \/> 8.2\tTesting of ease of dispersion <br \/> 8.2.1\tPreparation of the test samples <br \/> 8.2.2\tPressing and photometric measurement <br \/> 9\tEvaluation  <\/td>\n<\/tr>\n<tr>\n<td><b>11<b><\/td>\n<td>10\tTest report <br \/> 11\tPrecision  <\/td>\n<\/tr>\n<tr>\n<td><b>12<b><\/td>\n<td>Bibliography  <\/td>\n<\/tr>\n<\/table>\n","protected":false},"excerpt":{"rendered":"<p><b>Pigments and extenders.
