42、 radially outwards (downwards) for at least 30 min by attaching a mass of 90 kg. After being loaded in this way, check the lifebuoy visually for fractures or cracks and by measurement for any permanent deformation. 5.7 Load-carrying capacity Attach a steel weight with a mass of at least 15,3 kg to t

43、he lifebuoy. Let the lifebuoy with the attached steel weight float in freshwater. After 24 h, check whether the lifebuoy is still floating with the required buoyancy. 6 Designation A lifebuoy shall be designated (see example) by: a) the word “lifebuoy”, b) the number of this standard, c) the mass of

44、 the ring as specified in 4.4.
