R = 0,3 mm.NOTE Radius is given to prevent clothing getting caught.The internal dimensions are to be chosen so that a lifebuoy of 760 mm
17、outer diameter, 440 mm inner diameter and of 103 mm thickness with a grab line at its outer edge and a floatable line with a diameter of 8 mm to 11 mm and 30 m length, with or without throw line, fits into the housing.DIN ISO 18421:2016-08 6 4.2 Design4.2.1 InteriorThe interior of the housing shall
18、be designed so that neither the lifebuoy nor the life-line will fall off when the cover is opened and at the same time allows quick and easy access to both.4.2.2 CoverThe housing shall have a cover with bolting. The cover shall have a captive connection to the housing. The closing latches shall keep
19、 the door shut, but allow quick and easy access the lifebuoy.The design of the cover shall allow an easy access of the life buoy.The cover of the housing shall have a lifebuoy symbol to the outside and the plate with directions for rescue and resuscitation of drowning persons in accordance with ISO
20、18422 shall be fastened inside the inner circle of the lifebuoy symbol.4.2.3 MountingThe housing for lifebuoys shall be manufactured in such a way that it can be fixed to masts, posts and poles or onto walls or railings.These requirements are met if there are four bolt holes for the fixing of the ho
21、using through which threaded bolts can be inserted.4.3 MaterialThe housing shall be of a suitable material, e.g.: plastics (Pl); seawater-resistant aluminium (Al); hot-dip galvanised steel (HDG); stainless steel (Stst).4.4 ResistanceThe housing shall comply with the requirements in accordance with I
22、EC 60945 regarding the following:a) rain and spray water;b) sun radiation;c) resistance against oil;d) corrosion.4.5 Temperature stabilityThe utilizability of the housing shall remain constant at air temperatures of 25 C to +65 C.4.6 ColourThe external surface of the housing shall be orange or red.D

Test
24、ing shall be according to 5.4.5 Testing5.1 Scope and testingType approval test on one housing shall be carried out.The tests shall include the following individual tests as described below. The test is performed by visual inspection, function test and measuring.5.2 Visual inspection and functional t
25、estThe performance, the quality of the surface, the colour, the functioning of the indicating device, if applicable, and the feasibility to attach an indicating seal, if applicable, shall be tested by visual inspection and function test.5.3 ResistanceThe manufacturer shall present certificates provi
26、ng 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 housing shall be fixed according to the manufacturers instruction. The housing shall be filled with lifebuoy and the line as desc
