BS 354:2010 pdf download – Personal fall protection equipment — Lanyards
5.2.1 General conditioning Store sample lanyards at a temperature of (23 ± 5) °C and a humidity of (65 ± 5) % for at least 24 h.
5.2.2 Conditioning to wet and cold Immerse the sample lanyard in fresh water for a minimum of 1 h at a temperature of (23 ± 5) °C and then, within 90 s, place the sample lanyard in the refrigerated chamber for at least 4 h at a temperature of (-4+0/-2) °C.
5.2.3 Conditioning to very cold If the manufacturer claims that the lanyard can be used below -30°C, condition the sample lanyard in accordance with 5.2.1. Place the sample lanyard in the refrigerated chamber for at least 2 h at the minimum temperature claimed by the manufacturer with a maximum temperature of (- 30 ± 2) °C. 5.3 Examination of design 5.3.1 One unused lanyard shall be used for these examinations.
5.3.2 Verify by reference to appropriate documentation and by normal or corrected vision and/or tactile examination of the lanyard that it conforms to 4.1.1 to 4.1.5 inclusive.
5.3.3 For lanyards with a length adjustment device, verify by functional, visual and tactile examination that the length of the lanyard may be adjusted.
5.3.4 Attach one end of the sample to a suitable fixture. If the lanyard is adjustable, extend it to its maximum length. Apply a load without shock in the form of a mass of (10 ± 0,1) kg, or a corresponding force, to the other end of the lanyard. Maintain the load described above for (60 ± 15) s. Within 10 s, with the load still applied, measure the lanyard length L between the extremity load bearing points, in metres to the nearest 0,01 m (see Figure 1). If the lanyard has more than two terminations, measure the longest length combination of terminations allowed by manufacturer.
5.5 Examination of terminations Verify by reference to appropriate documentation, by normal or corrected vision and/or tactile examination and by measuring that the terminations of the lanyard conform to 4.3.
5.6 Slippage test for lanyards with a length adjustment device
5.6.1 Adjust the lanyard with a length adjustment device to its mid-length position. Mark the lanyard and the adjusting mechanism so that the marks align and so that a slippage can be assessed. 5.6.2 Condition the lanyard with a length adjustment device in accordance with 5.2.1.
5.6.3 Within 90 s of removal from the conditioning atmosphere, start to apply a static tensile force of (6,0 ± 0,1) kN between the two terminations of the lanyard, for a period of (3 25 , 0 0 + ) min in a static strength test apparatus which conforms to 4.1 of EN 364:1992. Remove the force and measure any slippage observed. 5.6.4 Carry out the test specified in 5.6.3 after adjusting and marking in accordance with 5.6.1 and conditioning in accordance with 5.2.2.
5.6.5 Carry out the test specified in 5.6.3 after adjusting and marking in accordance with 5.6.1 and conditioning in accordance with 5.2.3. NOTE A new sample lanyard with a length adjustment device may be used for each test.
5.7 Static strength test 5.7.1 Apparatus The static strength test apparatus shall conform to 4.1 of EN 364:1992.
5.7.2 Method NOTE A new sample lanyard may be used for each test.
220.127.116.11 If a textile lanyard is supplied with a connector conforming to EN 362 inserted in a termination, the connector shall be removed for the test.
18.104.22.168 After conditioning to 5.2, install the lanyard in the test machine within 90 s of removal from the conditioning atmosphere; submit the lanyard to the specified static test force defined in 4.5 between its two end points (supplied terminations). Maintain the force for a period of (3 25 , 0 0 + ) min and check if the lanyard sustains the force.
22.214.171.124 If the lanyard has more than two terminations, repeat the test in accordance with 126.96.36.199 for all possible combinations of termination, see Figure 2.
