This approach is called gas leakage test methodology. However, in this document it is recognized that other methodologies might be acceptable, provided that they demonstrate that any release of the radioactive contents will not exceed the regulatory requirements, and subject to agreement with the competent authority.<\/p>\n<p>This document provides both overall and detailed guidance on the complex relationships between an equivalent gas leakage test and a permissible activity release rate. Whereas the overall guidance is universally agreed upon, the use of the detailed guidance shall be agreed upon with the competent authority during the Type B(U), Type B(M) or Type C packages certification process.<\/p>\n<p>It should be noted that, for a given package, demonstration of compliance is not limited to a single methodology.<\/p>\n<p>While this document does not require particular gas leakage test procedures, it does present minimum requirements for any test that is to be used. It is the responsibility of the package designer or consignor to estimate or determine the maximum permissible release rate of radioactivity to the environment and to select appropriate leakage test procedures that have adequate sensitivity.<\/p>\n<p>This document pertains specifically to Type B(U), Type B(M) or Type C packages for which the regulatory containment requirements are specified explicitly.<\/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>7<b><\/td>\n<td>Foreword  <\/td>\n<\/tr>\n<tr>\n<td><b>8<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>12<b><\/td>\n<td>4 Symbols and units  <\/td>\n<\/tr>\n<tr>\n<td><b>15<b><\/td>\n<td>5 Regulatory requirements <br \/> 5.1 Relevant regulations <br \/> 5.2 Regulatory containment requirements <br \/> 6 Procedure for meeting the requirements of this document <br \/> 6.1 General  <\/td>\n<\/tr>\n<tr>\n<td><b>16<b><\/td>\n<td>6.2 Quality management system <br \/> 6.3 Procedure <br \/> 6.3.1 General  <\/td>\n<\/tr>\n<tr>\n<td><b>17<b><\/td>\n<td>6.3.2 Determination of permissible activity release rates  <\/td>\n<\/tr>\n<tr>\n<td><b>18<b><\/td>\n<td>6.3.3 Determination of standardized leakage rates <br \/> 6.3.4 Determination of permissible test leakage rates for each verification stage <br \/> 6.3.5 Selection of appropriate test methods <br \/> 6.3.6 Performance of test and record of results <br \/> 7 Determination of permissible activity release rates <br \/> 7.1 Step 1: List the radioactive contents, Ai <br \/> 7.2 Step 2: Determine the total releasable activity, RIT  <\/td>\n<\/tr>\n<tr>\n<td><b>19<b><\/td>\n<td>7.3 Step 3: Determine the maximum permissible activity release rates, R <br \/> 8 Determination of standardized leakage rates <br \/> 8.1 General  <\/td>\n<\/tr>\n<tr>\n<td><b>20<b><\/td>\n<td>8.2 Step 4: Determine the activity release rate due to permeation, RP <br \/> 8.3 Step 5: Determine the maximum permissible activity release rate due to leakage, RG <br \/> 8.4 Step 6: Determine the activity per unit volume of the containment system medium, C <br \/> 8.5 Step 7: Determine the maximum permissible volumetric leakage rate of the medium, L <br \/> 8.6 Step 8: Determine the maximum permissible equivalent capillary leak diameter, D  <\/td>\n<\/tr>\n<tr>\n<td><b>21<b><\/td>\n<td>8.7 Step 9: Determine the permissible standardized leakage rate, QSLR <br \/> 9 Containment-system verification requirements <br \/> 9.1 Containment-system verification stages <br \/> 9.1.1 General  <\/td>\n<\/tr>\n<tr>\n<td><b>22<b><\/td>\n<td>9.1.2 Design verification <br \/> 9.1.3 Fabrication verification <br \/> 9.1.4 Preshipment verification  <\/td>\n<\/tr>\n<tr>\n<td><b>23<b><\/td>\n<td>9.1.5 Periodic verification <br \/> 9.1.6 Maintenance verification <br \/> 9.2 Verification requirements <br \/> 9.2.1 General <br \/> 9.2.2 Step 10: Determine permissible test leakage rate for each verification stage, QTDA, QTDN, QTF, QTS, QTP and QTM <br \/> 9.2.3 Step 11: Select appropriate test methods  <\/td>\n<\/tr>\n<tr>\n<td><b>24<b><\/td>\n<td>10 Leakage test procedure requirements <br \/> 10.1 General <br \/> 10.2 Step 12: Perform tests and record results <br \/> 10.3 Test sensitivity <br \/> 10.4 Test procedure requirements <br \/> 10.4.1 General <br \/> 10.4.2 Testing  <\/td>\n<\/tr>\n<tr>\n<td><b>25<b><\/td>\n<td>Annex A (informative)  Preferred leakage test methods  <\/td>\n<\/tr>\n<tr>\n<td><b>39<b><\/td>\n<td>Annex B (informative)  Methods of calculation  <\/td>\n<\/tr>\n<tr>\n<td><b>44<b><\/td>\n<td>Annex C (informative)  Conversion tables  <\/td>\n<\/tr>\n<tr>\n<td><b>45<b><\/td>\n<td>Annex D (informative)  Worked examples  <\/td>\n<\/tr>\n<tr>\n<td><b>80<b><\/td>\n<td>Annex E (informative)  Rationale  <\/td>\n<\/tr>\n<tr>\n<td><b>93<b><\/td>\n<td>Bibliography  <\/td>\n<\/tr>\n<\/table>\n","protected":false},"excerpt":{"rendered":"<p><b>Safe transport of radioactive materials.
