BS 565:2017 pdf download – Mountaineering equipment – Tape – Safety requirements and test methods 1 Scope This European Standard specifies safety requirements and test methods for tape supplied on drums or in separate lengths, for use in mountaineering, including climbing. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. EN ISO 2307:2010, Fibre ropes – Determination of certain physical and mechanical properties (ISO 2307:2010) 3 Terms and definitions For the purposes of this document, the following term and definition applies. 3.1 tape long, narrow, flat textile structure intended to withstand forces, but not intended to absorb energy 4 Safety requirements 4.1 Stability When tested in accordance with 5.3, the weft yarn of the tape shall not be released from the tape sample. 4.2 Tensile strength When tested in accordance with 5.4, the tensile strength of tape shall be at least 10 kN. It shall be possible to read the tensile strength from the continuous tape (see 6.2). 4.3 Mass per unit length This mass shall be given as information according to 7 d). 5 Test methods 5.1 Test samples 5.1.1 Carry out the test described in 5.3 on one test sample. 5.1.2 Carry out the tests described in 5.4 on one test sample. 5.1.3 Carry out the test described in 5.5 on one test sample. 5.2 Conditioning and test conditions Dry the test samples for at least 24 h in an atmosphere of (50 ± 5) °C and less than 20 % relative humidity. Then condition these test samples in an atmosphere of (23 ± 2) °C and (50 ± 2) % relative humidity for at least 72 h. Then start testing these samples at a temperature of (23 ± 5) °C within 10 min. 5.3 Stability 5.3.1 Preparation Cut a sample of at least 200 mm length of tape without the influence of heat. Extract the weft yarn on both ends to allow the attachment of a test mass of (150 ± 5) g (see Figure 1). 5.3.2 Test Fix the test sample in a vertical orientation.Apply, without shock, the mass to the weft yarn of the lowerside for at least 1 min. Release the mass and check that the weft yarn...
