to aid location during darkness), to provide for additional hazards of the working environment (e.g twin-chamber buoyancy systems when there is a risk of damage to inflatable lifejackets), and the like They may be added as appropriate to any of the devices designated as compliant with CEN standards, from the largest lifejacket to the lightest buoyancy aid Owners, users and manufacturers of buoyancy devices, and those framing legislation, should specify additional items compliant with these standards when the foreseeable conditions of use make them desirable Manufacturers are also encouraged to fit them when possible to enhance the range of conditions for which devices are suited Each of these additional items is likely in the right conditions to contribute significantly to the

activation shall be preceded by exposure to an air temperature of (– 30 ± 1) °C for 8 +0,10 h, and the test activation shall be carried out in seawater at a temperature of (– ± 0,5) °C In these cases, achievement of at least the required minimum luminous intensity shall have occurred within a maximum of of activation In four more of the specimens tested, activation shall be performed in seawater at (30 ± 1) °C, and half the required minimum luminous intensity shall be achieved within 30 s of activation and the required minimum luminous intensity shall be achieved in 10 In the remaining four of the specimens tested, activation shall be performed in fresh water at 18 °C to 20 °C and the required minimum luminous intensity shall be achieved within 30 s of activation Following activation, each light shall emit the required minimum luminous intensity for a minimum of h continuously When measuring the luminous intensity, the photocell used shall subtend an angle of not more than 0.5° at the light source The distance of measurement shall be such that the law of the inverse of the square of the distance is applicable 4.3 Whistles 4.2.4 Marking 4.4.1 Types ｗｗｗ．ｂｚｆｘｗ．ｃｏｍ Part of the complete

distance of (5 ± 0,1) m directly in front of the whistle, at a predominant frequency of (2 ± 0,1) kHz The whistle shall also be shown to be capable of producing sound in air immediately following immersion in fresh water Whistles shall be attached to cord or line of a length sufficient to permit their use, which shall in turn be attached securely to the lifejacket or buoyancy aid They shall be stowed in a pocket on the device in such a way that the performance of the lifejacket is not affected, but so that they can be removed for use with either hand of the wearer, and can be stowed by the wearer Whistles complying with this standard shall be marked with the number of the EN standard to which they conform 4.4 Multi-chamber buoyancy systems These shall be of one of three types a) The buoyancy system can consist of two or more independently operating chambers which can be separated from each other In this case, each operating chamber shall when tested separately meet at least the requirements of EN 395, as regards material strength, inflation characteristics, performance standards, etc Licensed Copy: Institute Of Technology Tallaght, Institute of Technology, Thu Apr 12 10:11:30 GMT+00:00 2007, Uncontrolled Copy, (c) BSI EN 394:1994 b) The buoyancy system can consist of two or more independently operating chambers which cannot be separated from each other, and any one of which is capable of filling the entire lifejacket in the absence of inflation from others (most employ a “diaphragm” technique to achieve this) In this case, each operating chamber shall, when tested with the others uninflated, meet at least the requirements of EN 395 Each chamber shall be capable of providing a minimum of 100 % of the buoyancy required under the applicable lifejacket standard Each lifejacket shall be tested by first inflating one chamber fully to a pressure of (0,05 ± 0,01) kPa and then left for 30 +2 at a temperature of 15 °C to 25 °C 0 Each operating head shall then be fired in turn, allowing a 30+10 period between each, until all the chambers have been fully inflated, and the first has been inflated using two means (oral and gas) No rupture or visible damage shall result In the event that both chambers can be inflated orally, this test shall be repeated in full with the other chamber being inflated prior to firing each operating head c) The buoyancy system can consist of two or more independently operating chambers which cannot be separated from each other, and each of which provides a different and individual buoyancy, and all of which shall be capable of simultaneous inflation In this case, each operating chamber shall meet at least the requirements of EN 395 However, inflating all the available buoyancy chambers will result in a much higher total buoyancy than inflating any single one 4.4.2 Pressure testing A pressure drop test is to be undertaken with each inflatable chamber in turn, whilst all the other chambers are left vented to the free air Each chamber shall be inflated to an internal pressure of (3,5 ± 0,1) kPa for a period of 24+0,10 h, at the end of which there shall have been a loss of pressure by no more than 0,25 kPA 4.4.3 Buoyancy value Lifejackets which achieve the requirements of this standard shall be classified as having reached the standard appropriate to that of the combined maximum total buoyancy (i.e the maximum buoyancy resulting from the inflation of all the chambers simultaneously), provided that they meet the requirements of that standard in all other respects 4.4.4 Marking Lifejackets containing buoyancy systems complying with this standard shall be marked with the number of the EN standard to which they conform, postfixed with the words “multi-chamber buoyancy system” 4.5 Safety harness and lines 4.5.1 General Only safety harnesses and safety lines for yachtsmen which comply with EN 1095 shall be accepted as meeting the requirements of safety harnesses and safety lines When used in conjunction with or as an integral part of a lifejacket both the safety harness and the lifejacket shall be capable of operating to their specified performance whether the lifejacket is deployed or not, and whether the harness is attached to a safety line or not 4.5.2 Attachments Neither component, claimed to be usable in conjunction with the other, shall have any attachment which impairs the operation or performance of the other, or that is likely to cause damage to the other ｗｗｗ．ｂｚｆｘｗ．ｃｏｍ 4.5.3 Combinations Any integral combination or claimed permissible or usable combination of lifejacket and safety harness shall comply with the requisite standards on each individual item, and in each permissible combination Only then can the combination be stated and marked as complying with the appropriate EN standards Whilst it is not required that the combination be donned or doffed in a single operation, unless it is of permanently integral construction each component shall satisfy its required tests when in combination and when separated 4.5.4 Attachment and detachment of safety line Attachment and detachment of the safety line shall comply with EN 1095 4.5.5 Marking

relevant lifejacket standard, and themselves shall meet the material requirements of that standard, performing to the same levels in all tests except those of inflation as the inflatable chambers and main structural components as specified in that standard Lifejackets with protective covers complying with this standard shall be marked with the number of the EN standard to which they conform, postfixed with the words “protective cover” 4.7 Sprayhoods Sprayhoods shall normally be stowed in a position which puts them clear of the face of the wearer, which does not interfere with the normal operation of the lifejacket, and which is not a hazard, for example snagging on other objects They shall be able to be unstowed and deployed to protect the airway whilst the wearer is in the water, with the lifejacket fully deployed and inflated, if inflatable When deployed, they shall not impair the performance of the lifejacket in such a way as to render it no longer compliant with the relevant standard In particular, they shall be fitted with a clear area to enable the wearer to see sufficient of his surrounding as to aid his rescue If when deployed, the sprayhood reduces the effectiveness of any retroreflective material on the lifejacket itself, then the sprayhood shall itself provide an additional area at least equal to that obscured Sprayhoods shall be easily removable from their protective position, and shall be capable of being restowed so that they not fall back to their deployed position They shall also comply with the requirements of the carbon dioxide levels
