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...
