It is not applicable to the determination of water or nicotine-free dry particulate matter when using the extraction procedure specified in ISO&nbsp;4387:2000, 7.9.1 or the subsequent measurement of water specified in ISO&nbsp;10362\u20111 or ISO&nbsp;10362\u20112.<\/p>\n<blockquote>\n<p>NOTE The type of analytical smoking machine used could impact the mass of TPM collected on the smoke trap. This might be due to either incomplete collection or evaporation of water and other volatile compounds from the smoke trap.<\/p>\n<\/blockquote>\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>National foreword  <\/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>9<b><\/td>\n<td>1 Scope <br \/> 2 Normative references <br \/> 3 Terms and definitions  <\/td>\n<\/tr>\n<tr>\n<td><b>10<b><\/td>\n<td>4 Principle <br \/> 5 Apparatus  <\/td>\n<\/tr>\n<tr>\n<td><b>11<b><\/td>\n<td>6 Sampling <br \/> 7 Generation and collection of total particulate matter <br \/> 7.1 Preparation of the cigarettes for smoking <br \/> 7.1.1 General  <\/td>\n<\/tr>\n<tr>\n<td><b>12<b><\/td>\n<td>7.1.2 Selection of test portions from a bulk of Q cigarettes <br \/> 7.1.3 Selection of test portions from P packets <br \/> 7.1.4 Duplicate test portions <br \/> 7.2 Marking the butt length <br \/> 7.2.1 Standard butt length <br \/> 7.2.2 Measurement of length of filter  <\/td>\n<\/tr>\n<tr>\n<td><b>13<b><\/td>\n<td>7.2.3 Measurement of length of overwrap <br \/> 7.2.4 Butt length to be marked on the cigarettes before conditioning <br \/> 7.3 Sealing the filter ventilation holes <br \/> 7.4 Selection of cigarettes <br \/> 7.5 Conditioning  <\/td>\n<\/tr>\n<tr>\n<td><b>14<b><\/td>\n<td>7.6 Preliminary tests before smoking <br \/> 7.7 Smoking and collection of particulate matter <br \/> 7.7.1 Smoking plan <br \/> 7.7.2 Preparation of smoke traps and cigarette holders <br \/> 7.7.3 Setting up the smoking machine  <\/td>\n<\/tr>\n<tr>\n<td><b>15<b><\/td>\n<td>7.7.4 Procedure for smoking run  <\/td>\n<\/tr>\n<tr>\n<td><b>16<b><\/td>\n<td>7.8 Collection of total particulate matter <br \/> 7.9 Calculation of total particulate matter <br \/> 8 Test report  <\/td>\n<\/tr>\n<tr>\n<td><b>19<b><\/td>\n<td>Annex A(informative) Smoking plans  <\/td>\n<\/tr>\n<tr>\n<td><b>25<b><\/td>\n<td>Bibliography  <\/td>\n<\/tr>\n<\/table>\n","protected":false},"excerpt":{"rendered":"<p><b>Cigarettes.
