1 General
Carry out all tests at a temperature range of (23 ± 5) °C.
2 Conditioning
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.
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.
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 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.
Static strength
1 When tested in accordance with requirement of Static strength test, lanyards including any textile material or textile lanyard elements, e.g. synthetic fibre ropes or webbing, shall sustain a force of at least 22 kN.
2 When tested in accordance with requirement of Static strength test, lanyards made entirely of metallic elements shall sustain a force of at least 15 kN.
Dynamic strength for lanyards with a length adjustment device
When tested in accordance with requirement of Dynamic strength test for lanyards with a length adjustment device, the lanyard shall retain the test mass clear of the ground. Afterwards, the same lanyard shall, when tested in accordance with requirement of Static test for lanyard with a length adjustment device after the dynamic test, withstand a test force of (3 ± 0,3) kN, or an equivalent mass, applied for a period of (3 25,0 0 + ) min.
