This method is not applicable to resin impregnated fabrics.<\/p>\n<p>The method is suitable for use with fabrics such as woven or knitted fabrics, nonwovens, non-crimp fabrics, fabrics made of glass rovings or untwisted carbon filament yarns intended for reinforced composite materials. When applying the method to multi-axial non-crimp fabrics, the evaluation of the fibre orientation and gaps only incorporates the uppermost layer.<\/p>\n<p>The method can be used for fabrics treated with powder binder.<\/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>National foreword  <\/td>\n<\/tr>\n<tr>\n<td><b>4<b><\/td>\n<td>European foreword  <\/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>11<b><\/td>\n<td>4 Principle <br \/> 5 Apparatus <br \/> 5.2 Deformability test apparatus  <\/td>\n<\/tr>\n<tr>\n<td><b>13<b><\/td>\n<td>6 Test specimen  <\/td>\n<\/tr>\n<tr>\n<td><b>14<b><\/td>\n<td>7 Procedure <br \/> 7.1 Inserting the test specimen <br \/> 7.2 Specifications of the test <br \/> 7.2.1 Test parameters <br \/> 7.2.2 Evaluation parameters  <\/td>\n<\/tr>\n<tr>\n<td><b>15<b><\/td>\n<td>7.3 Test procedure <br \/> 8 Calculation and specification of the results <br \/> 8.1 Non-crimp fabric <br \/> 8.1.1 General  <\/td>\n<\/tr>\n<tr>\n<td><b>16<b><\/td>\n<td>8.1.2 Deformation force <br \/> 8.1.3 Gap width <br \/> 8.1.4 Gap portion <br \/> 8.1.5 Gap shape <br \/> 8.1.6 Fibre-angle change  <\/td>\n<\/tr>\n<tr>\n<td><b>17<b><\/td>\n<td>8.1.7 Undulation <br \/> 8.1.8 Loop formation <br \/> 8.1.9 Waviness <br \/> 8.1.10 Out-of-roundness <br \/> 8.2 Woven fabrics <br \/> 8.2.1 Characteristic value names, symbols and units  <\/td>\n<\/tr>\n<tr>\n<td><b>18<b><\/td>\n<td>8.2.2 Deformation force <br \/> 8.2.3 Gap portion <br \/> 8.2.4 Gap area <br \/> 8.2.5 Gap shape <br \/> 8.2.6 Fibre-angle change <br \/> 8.2.7 Undulation <br \/> 8.2.8 Shearing angle <br \/> 8.2.9 Waviness  <\/td>\n<\/tr>\n<tr>\n<td><b>19<b><\/td>\n<td>8.2.10 Out-of-roundness <br \/> 8.2.11 Residual deformation <br \/> 8.3 Knitted fabrics <br \/> 8.3.1 Table with characteristic value names, symbols and units <br \/> 8.3.2 Deformation force <br \/> 8.3.3 Gap portion <br \/> 8.3.4 Gap area <br \/> 8.3.5 Gap shape  <\/td>\n<\/tr>\n<tr>\n<td><b>20<b><\/td>\n<td>8.3.6 Waviness <br \/> 8.3.7 Out-of-roundness <br \/> 8.3.8 Residual deformation <br \/> 8.4 Nonwovens <br \/> 8.4.1 Table with characteristic value names, symbols and units <br \/> 8.4.2 Deformation force <br \/> 8.4.3 Anisotropy  <\/td>\n<\/tr>\n<tr>\n<td><b>21<b><\/td>\n<td>8.4.4 Thinning-out <br \/> 8.4.5 Waviness <br \/> 8.4.6 Out-of-roundness <br \/> 8.4.7 Residual deformation <br \/> 8.5 Evaluation  <\/td>\n<\/tr>\n<tr>\n<td><b>22<b><\/td>\n<td>9 Test report  <\/td>\n<\/tr>\n<tr>\n<td><b>24<b><\/td>\n<td>Annex A (informative) Example images  <\/td>\n<\/tr>\n<tr>\n<td><b>26<b><\/td>\n<td>Annex B (informative) Statistical data  <\/td>\n<\/tr>\n<tr>\n<td><b>27<b><\/td>\n<td>Bibliography  <\/td>\n<\/tr>\n<\/table>\n","protected":false},"excerpt":{"rendered":"<p><b>Textiles.
