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
