This method is designed to simulate typical anaerobic digestion conditions for the organic fraction of mixed municipal solid waste. The test material is exposed in a laboratory test to a methanogenic inoculum derived from anaerobic digesters operating only on pretreated household waste. The anaerobic decomposition takes place under high-solids (more than 20 % total solids) and static non-mixed conditions. The test method is designed to yield the percentage of carbon in the test material and its rate of conversion to evolved carbon dioxide and methane (biogas).<\/p>\n<p>The conditions described in this International Standard might not always correspond to the optimum conditions for the maximum degree of biodegradation to occur.<\/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>Introduction  <\/td>\n<\/tr>\n<tr>\n<td><b>8<b><\/td>\n<td>Section sec_1 <br \/> Section sec_2 <br \/> Section sec_3 <br \/> Section sec_3.1 <br \/> Section sec_3.2 <br \/> Section sec_3.3 <br \/> 1\tScope <br \/> 2\tNormative references <br \/> 3\tTerms and definitions  <\/td>\n<\/tr>\n<tr>\n<td><b>9<b><\/td>\n<td>Section sec_3.4 <br \/> Section sec_3.5 <br \/> Section sec_3.6 <br \/> Section sec_3.7 <br \/> Section sec_4 <br \/> Section sec_5 <br \/> Section sec_6 <br \/> 4\tPrinciple <br \/> 5\tTest environment <br \/> 6\tReagents  <\/td>\n<\/tr>\n<tr>\n<td><b>10<b><\/td>\n<td>Section sec_7 <br \/> Section sec_7.1 <br \/> Section sec_7.2 <br \/> Section sec_7.3 <br \/> Section sec_7.4 <br \/> Section sec_8 <br \/> Section sec_8.1 <br \/> 7\tApparatus <br \/> 8\tProcedure <br \/> 8.1\tPreparation of the inoculum  <\/td>\n<\/tr>\n<tr>\n<td><b>11<b><\/td>\n<td>Section sec_8.2 <br \/> Section sec_8.3 <br \/> Section sec_8.4 <br \/> 8.2\tPreparation of test material and reference material <br \/> 8.3\tStart-up of the test <br \/> 8.4\tIncubation period  <\/td>\n<\/tr>\n<tr>\n<td><b>12<b><\/td>\n<td>Section sec_8.5 <br \/> Section sec_9 <br \/> Section sec_9.1 <br \/> Section sec_9.2 <br \/> 8.5\tTermination of the test <br \/> 9\tCalculation and expression of results <br \/> 9.1\tCalculation of gaseous carbon <br \/> 9.2\tCalculation of the percentage biodegradation  <\/td>\n<\/tr>\n<tr>\n<td><b>13<b><\/td>\n<td>Section sec_9.3 <br \/> Section sec_9.4 <br \/> Section sec_10 <br \/> Section sec_11 <br \/> 9.3\tCalculation of loss in mass <br \/> 9.4\tExpression of results <br \/> 10\tValidity of results <br \/> 11\tTest report  <\/td>\n<\/tr>\n<tr>\n<td><b>15<b><\/td>\n<td>Annex sec_A <br \/> Table tab_d <br \/> Figure fig_A.1 <br \/> Annex A<br \/>\n(informative)<\/p>\n<p>Principle of test system  <\/td>\n<\/tr>\n<tr>\n<td><b>16<b><\/td>\n<td>Annex sec_B <br \/> Annex B<br \/>\n(informative)<\/p>\n<p>Example of loss in mass determination  <\/td>\n<\/tr>\n<tr>\n<td><b>17<b><\/td>\n<td>Reference ref_1 <br \/> Reference ref_2 <br \/> Reference ref_3 <br \/> Reference ref_4 <br \/> Bibliography  <\/td>\n<\/tr>\n<\/table>\n","protected":false},"excerpt":{"rendered":"<p><b>Plastics.
