BS EN 564 This European Standard specifies safety requirements and test methods for accessory cord comprising a coreand a sheath, supplied on a drum or in separate lengths, for use in mountaineering including climbing.
The following referenced documents are indispensable for the application of this document. For dated refer-ences, only the edition cited applies. For undated references, the latest edition of the referenced document(including any amendments) applies.
EN ISO 139,Textiles — Standard atmospheres for conditioning and testing (ISo 139:2005)
EN ISO 2307:2005, Fibre ropes — Determination of certain physical and mechanical properties (ISo2307:2005)
For the purposes of this document, the following term and definition applies.
accessory cord cord or rope, comprising a core and a sheath, that has a nominal diameter of 4 mm to 8 mm and is intended towithstand forces, but not intended to absorb energy.The nominal diameter dnom shall be one of the values given in Table 1.Carry out the test at a relative humidity which may be outside the standard atmosphere given in EN ISO 139but at a temperature of (23 ± 5)°C, in which case the test shall begin within 5 min of removal from conditioning atmosphere.
Measure the actual diameter dr under a load of (4 ± 0,05) kg after the latter has been applied for (60 ± 15)s.Ensure that the cross-sectional area of the accessory cord is not subjected to any deformation during themeasurement.
Take the measurements in two directions around the diameter, starting at points 90° apart, at each of threelocations approximately 300 mm apart. The length of the contact areas of the measuring instrument shall be(50 ± 1) mm.
Report the arithmetic mean of the six measurements, to the nearest 0,1 mm.
Carry out the determination of the tensile strength by using a tensile testing machine and fixing devices in ac:cordance with 5.1 of EN ISO 2307:2005.
The minimum free length between attachment points shall be 200 mm.BS EN 564 pdf download.
