EN 565-2017 pdf download.Mountaineering equipment – Tape – Safety requirements and test methods.
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.
5.3.2 Test
Fix the test sample in a vertical orientation. Apply without shock, the mass to the weft yarn of the lower side for at least 1 mm. Release the mass and check that the weft yarn has not unravelled and the test mass stays in a stable position. Repeat the test on the weft yarn of the other end of the test sample.
5.4 Determination of tensile strength
Carry out the determination of the tensile strength by using a tensile testing machine and fixing devices
in accordance with 5.1 of EN ISO 2307:2010.
The minimum length between attachment points shall be 200 mm.
Determine the loading speed, v, as a function of the length of the test sample, using Formula (1):
v = 05 lwith an accuracy of± 20% (1)
where
v is the loading speed in millimetres per minute;
l is the length in millimetres between points of attachment.
5.5 Determination of mass per unit length
Carry out the test with a minimum length of 1 300 mm between attachment points.
NOTE There is no requirement for any particular type of fixing device.
Load the test sample without shock at a rate not exceeding 1 mm/s by means of a (4 ± 0,05) kg test mass.
Retain the maximum load for (60 ± 15)s and mark a reference length oI(1 000 ± 1) mm, with a distance between the marks and the attachment points of at least 100 mm.
Release the load, then cut the marked part from the test sample and determine its mass to the nearest
0,1 g.
Record the mass per unit length in grams per metre, to at least two significant figures.
There is no specific requirement for mass per unit length, but it can be marked on the drum or
packaging of the tape (see Clause 6).
6 Marking
6.1 The drum or production line packaging of tapes shall be marked with at least the following:
a) number of this European Standard, i.e. EN 565;
b) name of the manufacturer’
c) tensile strength which the manufacturer ensures at the time of manufacturing:
d) if tape is supplied on a drum, it shall be of the same type, specification and batch of manufacture, and if it consists of more than one piece, the number of pieces shall be stated on the drum;
e) year of manufacture;
NOTE In addition, the mass per unit length can also be marked.
f) graphical symbol (see Figure 2), which advises the user to read the information supplied by the manufacturer,
Figure 2 — Operator’s manual (according to ISO 7000, Symbol No. 1641)
6.2 The tape shall be marked by means of threads to allow the minimum tensile strength to be read directly, as follows:
a) one coloured thread per S kN tensile strength;
h) colour of the thread(s) shall be uniform and in contrast to the colour of the tape;EN 565-2017 pdf download.
