9 Line-Throwing Appliances

Parent topic: Part 1 - Prototype Test for Life-Saving Appliances

9.1 Tests for pyrotechnics

 Rockets used in line-throwing appliances should be subjected to the tests prescribed in 4.3.1, 4.3.3, 4.4, 4.5.1 (if appropriate), 4.5.5 and 4.5.6.

9.2 Function test

 Three projectiles should be fired connected to a line and should carry the line at least 230 m in calm conditions. The lateral deflection from the line of firing should not exceed 10% of the length of flight of the projectile. If the projectile is fired using an explosive charge, then one of the projectiles should be fired using double the normal charge.

9.3 Line tensile test

 The line should be subjected to a tensile test and should have a breaking strain of not less than 2 kN.

9.4 Visual examination

 It should be established by visual examination that the appliance:

  • .1 is marked with clear and precise instructions on how it should be operated; and

  • .2 is marked with a means of determining its age.

9.5 Temperature test

 Three individual units, consisting of projectile, firing system and line should be subjected to the temperature cycling prescribed in 4.2.1 and one specimen subjected to each of the tests prescribed in 4.2.2, 4.2.3 and 4.2.4.
