All fabrics covered by this specification are plain weave. This specification determines the nomenclature, definitions, general and chemical requirements for the glass, and physical requirements for finished woven glass fibre fabrics. Annex A of this standard provides a style designator for each finished fabric glass style, with specifications on yarn, fabric count, thickness and weight in both SI and US system.<\/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>5<b><\/td>\n<td>English <br \/> CONTENTS  <\/td>\n<\/tr>\n<tr>\n<td><b>7<b><\/td>\n<td>FOREWORD  <\/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 Visual requirements <br \/> Tables <br \/> Table 1 \u2013 Classification of defects  <\/td>\n<\/tr>\n<tr>\n<td><b>13<b><\/td>\n<td>5 Physical requirements <br \/> 5.1 Fabric count <br \/> 5.2 Weave type <br \/> 5.3 Fabric thickness <br \/> 5.4 Fabric weight <br \/> 5.5 Fabric length <br \/> 5.6 Fabric width <br \/> 5.7 Feather length <br \/> 5.8 Filament diameter <br \/> Table 2 \u2013 Filament diameter designations  <\/td>\n<\/tr>\n<tr>\n<td><b>14<b><\/td>\n<td>5.9 Bare glass nominal measurement <br \/> 6 Chemical requirements <br \/> 7 Electrical requirements <br \/> 7.1 Dielectric constant <br \/> 7.2 Dissipation factor <br \/> Table 3 \u2013 Bare glass nominal measurements  <\/td>\n<\/tr>\n<tr>\n<td><b>15<b><\/td>\n<td>8 Workmanship requirements <br \/> 8.1 Splices <br \/> 8.2 Laser machinability performance <br \/> 8.3 Alternate fabric styles and weaves <br \/> 9 Quality assurance <br \/> 9.1 Statistical process control (SPC)   <\/td>\n<\/tr>\n<tr>\n<td><b>16<b><\/td>\n<td>9.2 Responsibility for inspection  <br \/> 9.3 Test equipment and inspection facilities  <br \/> 9.4 Preparation of samples  <br \/> 9.5 Standard laboratory conditions  <br \/> 9.6 Inspection requirements and acceptability <br \/> 9.6.1 General  <br \/> 9.6.2 Sample size  <br \/> Table 4 \u2013 Sample size per number of rolls shipped   <\/td>\n<\/tr>\n<tr>\n<td><b>17<b><\/td>\n<td>9.6.3 Sampling plans <br \/> 9.6.4 Acceptable quality level (AQL) <br \/> 9.7 Test methods <br \/> 9.7.1 Fabric appearance  <br \/> Table 5 \u2013 Sample size per length of individual roll shipped and the acceptable quality level  <\/td>\n<\/tr>\n<tr>\n<td><b>18<b><\/td>\n<td>9.7.2 Fabric count  <br \/> 9.7.3 Weave type  <br \/> 9.7.4 Fabric thickness  <br \/> 9.7.5 Weight per unit area   <\/td>\n<\/tr>\n<tr>\n<td><b>19<b><\/td>\n<td>9.7.6 Fabric length  <br \/> 9.7.7 Fabric width  <br \/> 9.7.8 Finish level (organic content)   <\/td>\n<\/tr>\n<tr>\n<td><b>20<b><\/td>\n<td>9.7.9 Bias or bowed filling  <br \/> 10 Preparation for delivery <br \/> 10.1 Preservation and packaging  <br \/> 10.2 Packing <br \/> 10.3 Marking <br \/> 11 Additional information <br \/> 11.1 Ordering data  <br \/> 11.2 New styles   <\/td>\n<\/tr>\n<tr>\n<td><b>21<b><\/td>\n<td>Annex A (normative)Finished fabric glass styles in SI units  <\/td>\n<\/tr>\n<tr>\n<td><b>24<b><\/td>\n<td>Bibliography  <\/td>\n<\/tr>\n<\/table>\n","protected":false},"excerpt":{"rendered":"<p><b>Materials for printed boards and other interconnecting structures &#8211; Sectional specification set for reinforcement materials.
