33、pplicable, shall be tested by visual inspection and function test.5.3 ResistanceThe manufacturer shall present certificates proving that the relevant requirements in 4.4 and 4.5 are fulfilled.5.4 Strength testThe test shall be carried out at an ambient temperature of +20 C 5 C.Prior to the test the
34、housing shall be fixed according to the manufacturers instruction. The housing shall be filled with lifebuoy and the line as described in 4.1 and closed.Then a textile belt of a width of 35 mm 5 mm with means for attaching the test weight shall be placed around the housing. With this, the test weigh
35、t of 100 kg shall be applied to the belt and maintained for 60 s.During and after the test, the housing shall neither become loosened from the fixation nor show any malfunction nor permanent deformation or damage.5.5 Mounting instructionThe manufacturer shall provide mounting instructions.6 Designat
