It includes the detailed requirements for S2 sheathing materials and other components called up in the separate parts.<\/p>\n<blockquote>\n<p>NOTE Detailed requirements for insulation systems are given in EN 50306-2.<\/p>\n<\/blockquote>\n<p>In particular, EN 50306-1 specifies those requirements relating to fire safety which enable the cables to satisfy Hazard Level 3 of EN 45545-1 and EN 45545-2.<\/p>\n<p>These cables are rated for occasional thermal stresses which causes ageing equivalent to continuous operational life at a temperature of 105 \u00b0C or 90 \u00b0C. For standard cables, this is determined by the acceptance test defined in EN 50305, using accelerated long-term (5 000 h) thermal ageing indicating a 125 \u00b0C or 110 \u00b0C \/20 000 h temperature index. If the customer were to require lifetime predictions, this would be demonstrated based on the temperature index of the product as supplied by the manufacturer. The maximum temperature for short circuit conditions is 160 \u00b0C based on duration of 5 s.<\/p>\n<p>EN 50306-1 is expected to be used in conjunction with one or more of the other parts of EN 50306.<\/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>8<b><\/td>\n<td>1 Scope <br \/> 2 Normative references  <\/td>\n<\/tr>\n<tr>\n<td><b>9<b><\/td>\n<td>3 Terms and definitions  <\/td>\n<\/tr>\n<tr>\n<td><b>10<b><\/td>\n<td>4 Rated voltage  <\/td>\n<\/tr>\n<tr>\n<td><b>11<b><\/td>\n<td>5 Marking <br \/> 5.1 Indication of origin <br \/> 5.2 Continuity of marks <br \/> 5.3 Durability <br \/> 5.4 Legibility  <\/td>\n<\/tr>\n<tr>\n<td><b>12<b><\/td>\n<td>5.5 Additional marking <br \/> 5.6 Use of the name CENELEC <br \/> 6 General requirements for the construction of cables <br \/> 6.1 Conductors <br \/> 6.1.1 Material <br \/> 6.1.2 Construction <br \/> 6.1.3 Check of construction <br \/> 6.1.4 Electrical resistance <br \/> 6.2 Insulation system <br \/> 6.2.1 Material <br \/> 6.2.2 Application <br \/> 6.2.3 Thickness and concentricity  <\/td>\n<\/tr>\n<tr>\n<td><b>13<b><\/td>\n<td>6.3 Fillers and tapes <br \/> 6.3.1 Material <br \/> 6.3.2 Application <br \/> 6.4 Inner sheath <br \/> 6.4.1 Material <br \/> 6.4.2 Application <br \/> 6.4.3 Thickness <br \/> 6.5 Metallic screen <br \/> 6.5.1 Type of screen <br \/> 6.5.2 Application <br \/> 6.6 Sheath <br \/> 6.6.1 Material  <\/td>\n<\/tr>\n<tr>\n<td><b>14<b><\/td>\n<td>6.6.2 Application <br \/> 6.6.3 Thickness <br \/> 6.7 Overall diameter <br \/> 7 Electrical performance <br \/> 8 Fire performance &#8211; cables <br \/> 8.1 Flame propagation (flame spread) &#8211; single vertical cable <br \/> 8.2 Flame propagation (flame spread) &#8211; bunched cables <br \/> 8.2.1 Cables with diameter more than or equal to 12 mm <br \/> 8.2.2 Cables with diameter greater than 6 mm and less than 12 mm  <\/td>\n<\/tr>\n<tr>\n<td><b>15<b><\/td>\n<td>8.2.3 Cables with diameter not greater than 6 mm <br \/> 8.3 Smoke emission <br \/> 9 Fire performance &#8211; components <br \/> 9.1 Tests for corrosive and acid gas emission, and for fluorine <br \/> 9.2 Toxicity  <\/td>\n<\/tr>\n<tr>\n<td><b>17<b><\/td>\n<td>Annex A (normative)Thickness and overall diameterSelection of samples and calculation of results <br \/> A.1 Insulation thickness <br \/> A.1.1 Procedure <br \/> A.1.2 Evaluation of results <br \/> A.1.3 Concentricity <br \/> A.2 Measurement of sheath thickness <br \/> A.2.1 Procedure <br \/> A.2.2 Evaluation of results <br \/> A.3 Measurement of overall diameter  <\/td>\n<\/tr>\n<\/table>\n","protected":false},"excerpt":{"rendered":"<p><b>Railway applications.
