Climbing ropes have to\u00a0meet the minimal\u00a0standards set by the European Union (CE) and can apply to pass\u00a0also the higher standards set by the International Climbing and Mountaineering Federation (UIAA). On this article we will have a<br \/>general view on the\u00a0ropes that are currently on the market and understand all the tests they have to pass,\u00a0learning what those signs on the label mean.<\/p>\n<p>First of all, let&#8217;s look inside a rope! Climbing ropes are made of an internal<span>\u00a0<\/span><em>kernel<\/em>, composed of filaments woven in bobbins, and an external<span>\u00a0<\/span><em>mantle<\/em>, which is a protective sheath. While the mantle is vital to preserve the filaments from damage caused by abrasion, humidity and solar light, it is the kernel which does the thought job, holding<br \/>circa 70% of the tension.<\/p>\n<p>Since 2010\u00a0<a href=\"http:\/\/www.beal-planet.com\/en\/\" target=\"_blank\" rel=\"noopener noreferrer\">Beal<\/a>\u00a0produces climbing ropes with their new\u00a0design\u00a0Unicore, which binds the sheath to the kernel (core),\u00a0preventing slippage and\u00a0dramatically reducing the possibility of falling when the sheath\u00a0is cut\u00a0under load.<\/p>[\/et_pb_text][\/et_pb_column][\/et_pb_row][et_pb_row _builder_version=&#8221;4.4.8&#8243;][et_pb_column type=&#8221;4_4&#8243; _builder_version=&#8221;4.4.8&#8243;][et_pb_text admin_label=&#8221;UIAA guidance&#8221; _builder_version=&#8221;4.4.8&#8243;]<h3 style=\"text-align: center;\">UIAA guidelines for DRY\u00a0ropes<\/h3>\n<p>The UIAA has released in 2014 the guidelines illustrating\u00a0their new Water Repellent standard.

textwidget\">\n<p>What makes climbing ropes so special is their elasticity, and this is why they are called<span>\u00a0<\/span><em>dynamic<\/em>.<\/p>\n<p>During a fall a climber is subjected to acceleration\u00a0at\u00a0first, and sudden deceleration at the end of the fall. The purpose of elongation is do absorb and dissipate the impact force produced at the end of a fall, avoiding the final recoil. Numerous researches proved that the max impact force a human being can tolerate is about 15 times one\u2019s own body weight<a href=\"https:\/\/climbingsardinia.com\/climbing-info\/equipment\/climbing-ropes\/#_ftn4\" name=\"_ftnref4\">[1]<\/a>. This means that a person weighting 80 kg can tolerate an impact force not higher than 12kN<a href=\"https:\/\/climbingsardinia.com\/climbing-info\/equipment\/climbing-ropes\/#_ftn5\" name=\"_ftnref5\">[2]<\/a>. Ropes should thus be enough elastic to dissipate the\u00a0impact force that passes\u00a012kN.<\/p>\n<p>&nbsp;<\/p>\n<p>&nbsp;<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<div id=\"pg-543-3\" class=\"panel-grid panel-has-style\">\n<div data-overlay=\"true\" class=\"panel-row-style panel-row-style-for-543-3\">\n<div id=\"pgc-543-3-0\" class=\"panel-grid-cell\">\n<div id=\"panel-543-3-0-0\" class=\"so-panel widget widget_sow-editor panel-first-child panel-last-child\" data-index=\"3\">\n<div class=\"so-widget-sow-editor so-widget-sow-editor-base\">\n<h3 class=\"widget-title\" style=\"text-align: center;\">WHAT DIAMETER SHOULD MY ROPE BE?<\/h3>\n<div class=\"siteorigin-widget-tinymce textwidget\">\n<p>In the last 20 years, thanks to new materials and manufacturing techniques, the diameter and weight of climbing ropes have drastically diminished. The majority of climbing ropes on the market have a diameter smaller than 10mm.\u00a0Thin ropes are appreciated for their ease of use, but they wear faster.<\/p>\n<p>Diameter always comes in relationship with weight, and when buying a rope it is important to know both measures. When comparing two ropes of the same diameter for example, we should pay attention to their weight too. The label on a new rope should show both measures in grams per meter (g\/m).<\/p>\n<p>Watch out for misconceptions: while a thick rope is not necessarily safer or stronger than a thinner one, a thinner rope does not necessarily weight less than a thicker one.<\/p>\n<p>When choosing what rope to buy, pay attention also to which belay device you and your climbing partners will be using. Some devices can only work with thick ropes, while other are designed for new and thinner ropes.The old GriGri for example does not accept ropes thinner than 10mm, while the MicroJul works best with 7mm ropes.

Single ropes are are the most resistant and long,\u00a0 and thus can be used one at the time, to belay a climber or to rappel.\u00a0 Single ropes come in length of 60, 70 or 80 meters. While in countries like England it is hard to find lengthy climbing routes, it is vital to have at 70 meters rope in Sardinia, as many problems are 35 meters high. Single ropes&#8217;<strong><span>\u00a0<\/span>diameter<\/strong><span>\u00a0<\/span>varies from the old 11mm to the actual 8.6mm.<a href=\"https:\/\/climbingsardinia.com\/climbing-info\/equipment\/climbing-ropes\/#_ftn2\" name=\"_ftnref2\">[4]<\/a><\/p>\n<p><strong>Half ropes<\/strong><span>\u00a0<\/span>must be used in pairs. They are normally used for multi-pitches and trad climbing. Apart from double security, half ropes allow climbers to rappel faster, using the entire length of the ropes, descending 50 or 60 meters instead of 30. The diameter of half ropes is generally smaller than single ropes, and varies from 9mm to 7.3 mm<a href=\"https:\/\/climbingsardinia.com\/climbing-info\/equipment\/climbing-ropes\/#_ftn3\" name=\"_ftnref3\">[5]<\/a>.<\/p>\n<p>Knowing that these ropes can only be used in pairs, we recommend<span>\u00a0<\/span><em>buying<\/em><span>\u00a0<\/span>them in pairs. This is to make sure you are always using a good pair of ropes and not recycling an old one in rough conditions.<\/p>\n<p>A pair of half ropes should have the<span>\u00a0<\/span><em>same length<\/em>, to prevent falls when rappelling or other similar incidents. It helps to have ropes of the same diameter, and it is recommendable to have them in different colours.<\/p>\n<p>It exist also another kind of rope, twin ropes, which is now disappearing from the market as replaced by single ropes. Although they are thicker than half ropes, they must be used in pairs and clipped together on each quickdraw.<\/p>\n<p>&nbsp;<\/p>\n<div id=\"pg-543-7\" class=\"panel-grid panel-has-style\">\n<div data-overlay=\"true\" class=\"panel-row-style panel-row-style-for-543-7\">\n<div id=\"pgc-543-7-0\" class=\"panel-grid-cell\">\n<div id=\"panel-543-7-0-0\" class=\"so-panel widget widget_sow-editor panel-first-child\" data-index=\"10\">\n<div data-title-color=\"#443f3f\" data-headings-color=\"#443f3f\" class=\"panel-widget-style panel-widget-style-for-543-7-0-0\">\n<div class=\"so-widget-sow-editor so-widget-sow-editor-base\">\n<h3 class=\"widget-title\" style=\"text-align: center;\">STATIC RESISTANCE<\/h3>\n<div class=\"siteorigin-widget-tinymce textwidget\">\n<p>To pass homologation by European Norms, climbing ropes should not break under a steadily pulling before reaching 18kN.

For a rope to lose resistance it is not necessary to be completely drenched, even thin rain affects its performance. All ropes actually on the market are treated either with chemical agents (Superdry or GoldenDry) or heating techniques (Duraflex or Dry Cover) to prevent water and dirt affecting their resistance.<\/span><\/p>\n<p style=\"text-align: justify;\"><span style=\"color: #ffffff;\">Funny enough, a frosted rope loses only 50% of its initial resistance.<\/span><\/p>\n<p style=\"text-align: justify;\"><span style=\"color: #ffffff;\">If a rope undergoes abrasion or a heavy fall when wet, it is strongly recommended to stop using it.<strong>\u00a0Ropes recover the 100% of their resistance once dried out<\/strong>. It is important to dry ropes away from direct sun light, as UV rays damage the external nylon fibres.<\/span><\/p>\n<h3 style=\"text-align: center;\"><span style=\"color: #ffffff;\"><strong>Dust<\/strong><\/span><\/h3>\n<p style=\"text-align: justify;\"><span style=\"color: #ffffff;\">If a rope is exposed to dust and mud, microcrystals penetrate the sheath and affect the performance of the kernel. Even the friction against anchoring points, karabiners and belay devices frees particles of aluminium that deposit on the sheath.<\/span><\/p>\n<p style=\"text-align: justify;\"><span style=\"color: #ffffff;\">If a rope is dirty and leaves your hands black when belaying, you can be sure microcrystals have deposited on and penetrated the sheath. Subsequent friction (against anchoring points and belay devices) can only press the microcrystals against the internal bobbins, causing damages to the nylon fibres.<\/span><\/p>\n<h3 style=\"text-align: center;\"><span style=\"color: #ffffff;\">Cleaning ropes<\/span><\/h3>\n<p><span style=\"color: #ffffff;\">To keep a rope clean it is good practice to brush it after each use, by using special spiral-shaped brushes.<\/span><\/p>\n<h4 style=\"text-align: center;\"><span style=\"color: #ffffff;\">Washing ropes<\/span><\/h4>\n<p style=\"text-align: justify;\"><span style=\"color: #ffffff;\">All manufacturers claim it safe, and also necessary, to wash dirty ropes in lukewarm water with no strong or improper cleaning agents. Although we recommend washing a climbing rope by hand, it is safe to use washing machines. We advice placing the rope inside a cotton bag (such as a pillow case) and throw it in a washing machine avoiding soap, high temperatures (30 deg. Celsius is fine) and tumble-drying. Dry the rope on shady and ventilated areas, uncoiling and moving it every now and then to avoid mould.<\/span><\/p>\n<p style=\"text-align: justify;\"><span style=\"color: #ffffff;\">We know by experience that after you wash a rope something will not be quite right with it. If a wash makes it lose its external dry treatment, the rope will be exposed to faster water and dust assimilation. But most importantly you will experience stronger friction on belay devices, making the rope very uncomfortable to use.<\/span><\/p>\n<p style=\"text-align: justify;\"><span style=\"color: #ffffff;\">To avoid stronger friction and faster abrasion we advise to complement the washing using wet-protection agents, which you can easily buy from the same rope manufacturer.

The last quickdraw must thus withstand two equal forces: one on the climber and one on the belayer side. This doubling of forces is known as Pulley effect, or Parallelogram of forces.<\/span><\/p>\n<p style=\"text-align: justify;\"><span style=\"color: #ffffff;\">Climbing ropes are dynamic and absorb part of the impact force, transmitting no more than 12kN to the climber. The rope pulling the last quickdraw at the end of a fall will probably exert a force of 12kN on the climber side, and 12kN on the belayer side too.<\/span><\/p>\n<p style=\"text-align: justify;\"><span style=\"color: #ffffff;\">In reality many factors contribute to lower the force on the last quickdraw. The belayer side of the rope often pulls only with two\/thirds of the force, reducing it to 8kN, and the angle of the rope also plays a crucial part. While 0 degrees angles double the force, 90 degrees angles increase the force of 1.5 times only and finally 120 degrees angles do not increase the force at all.<\/span><\/p>\n<p style=\"text-align: justify;\"><span style=\"color: #ffffff;\">The reason why European Standards require all climbing equipment to withstand a force of about 22kN is due to the combination of the dissipation of the impact force by rope elongation and the doubling effect caused by the parallelogram of forces.<\/span><\/p>\n<p><span style=\"color: #ffffff;\"><\/span><\/p>[\/et_pb_toggle][et_pb_toggle title=&#8221;FALL FACTOR&#8221; open_toggle_text_color=&#8221;#edf000&#8243; icon_color=&#8221;#ffffff&#8221; _builder_version=&#8221;4.4.8&#8243; title_text_color=&#8221;#ffffff&#8221; title_text_align=&#8221;center&#8221; background_color=&#8221;#e02b20&#8243; hover_enabled=&#8221;0&#8243; closed_toggle_text_color=&#8221;#ffffff&#8221; text_orientation=&#8221;justified&#8221; title_font=&#8221;|600|||||||&#8221;]<h3 style=\"text-align: center;\"><span style=\"color: #ffffff;\">Why is the fall factor important in climbing?<\/span><\/h3>\n<span style=\"color: #ffffff;\">During a fall a climber gains great speed towards the ground, generating kinetic force that at the end of the fall is transmitted in part to the series of equipment used for the climb (harness, rope, quickdraws) and in part to the climber.<\/span>\n\n<span style=\"color: #ffffff;\">The most dangerous part of a fall in an ideal situation, ignoring case-specific dangers such as rock ledges, is the final part: when the rope extends and the climber has to withstand the force caused by sudden deceleration.<\/span>\n\n<span style=\"color: #ffffff;\">Studies carried out by the Air Force proved that the maximum impact force a person can withstand is about 15 times his or her weight. If falling head-down the maximum force a person can withstand is reduced to 4 times his or her weight.<\/span>\n\n<span style=\"color: #ffffff;\">If a person weights 80kg, the maximum impact force he or she can withstand is 80 x 15 = 1200 kg.\u00a0\u00a0 (1200 kg correspond to more or less 1200 daN, or 1.2 kN)<\/span>\n<h3 style=\"text-align: center;\"><span style=\"color: #ffffff;\">How do you calculate the Fall Factor?<\/span><\/h3>\n<p style=\"text-align: justify;\"><span style=\"color: #ffffff;\">The\u00a0<strong>Fall Factor<\/strong>\u00a0is a relationship between the height of the fall, the length of the rope between the climber and the last anchoring point. It is expressed in decimal values, which in sport and alpine climbing go from a minimum of 0 to a maximum of 2. In certain cases, like in via ferrata, the value can be higher than 2, but in this article we will concentrate on the basic understanding of sport climbing fall factor.

The lead climber starts climbing the second pitch but after 2 meters he or she falls before being able to place the first quickdraw.

Climbing ropes absorb the impact force by elongation, usually transmitting an impact force between 800 and 900 daN, depending on manufacturer and model. With use and wear a rope becomes less elastic, increasing thus the impact force transmitted at the end of a fall.<\/span>\n\n<span style=\"color: #ffffff;\">When buying a new climbing rope it is important to check all the measures stated on the label.
