It is applicable for assessing the effect of water-soluble and solid matter bounded non-volatile contaminants in natural samples, such as soils and waste materials. Although not the main purpose, the contact test can additionally be used for testing the effect of chemicals, as described in the Annex&nbsp;C. The test yields a result within 6&nbsp;h and can therefore be used for screening potentially contaminated test material.<\/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>12<b><\/td>\n<td>5.1 Test organisms  <br \/> 5.2 Control substrates  <br \/> 5.2.1 General  <br \/> 5.2.2 Control for soils   <\/td>\n<\/tr>\n<tr>\n<td><b>13<b><\/td>\n<td>5.2.3 Control for waste material  <br \/> 5.3 Test substrates   <\/td>\n<\/tr>\n<tr>\n<td><b>14<b><\/td>\n<td>5.4 Reagents   <\/td>\n<\/tr>\n<tr>\n<td><b>17<b><\/td>\n<td>7.1 Preparation of dilutions  <br \/> 7.2 Reference substances and positive control preparation   <\/td>\n<\/tr>\n<tr>\n<td><b>18<b><\/td>\n<td>7.3 Contact test procedure  <br \/> 7.3.1 General  <br \/> 7.3.2 Aeration   <\/td>\n<\/tr>\n<tr>\n<td><b>19<b><\/td>\n<td>7.3.3 Deactivation  <br \/> 7.3.4 Preparation of the inoculum  <br \/> 7.3.5 Incubation and fluorescence measurement  <br \/> 7.4 Interferences   <\/td>\n<\/tr>\n<tr>\n<td><b>20<b><\/td>\n<td>8.1 Calculation  <br \/> 8.1.1 Relative fluorescence  <br \/> 8.1.2 Determining the percentage of inhibition  <br \/> 8.2 Expression of results   <\/td>\n<\/tr>\n<\/table>\n","protected":false},"excerpt":{"rendered":"<p><b>Soil quality.
