21、00 r 200: (50 10) % r 400: 95 % III 100 r 200: (50 10) % r 400: 70 % aFor tank showers the water distribution of Class III applies irrespective of the volume flow rate (see also 4.3.3). 5 DIN 12899-3:2009-04 4.2 Flow rate of water 4.2.1 Plumbed-in body showers The water supplied by plumbed-in body s
22、howers shall be of a constant flow rate discharged overhead in accordance with one of the three classes given in Table 1 at a flow pressure to be specified by the manufacturer. The plumbed-in body shower shall be capable of delivering this supply for a minimum of 15 minutes. NOTE Attention is drawn
23、to possible national regulations concerning the volume flow rate. During the type test (see 4.3.1), the flow pressure shall be measured with a fully opened valve at the point where the shower is connected to the water supply. The measured value shall be indicated in the manufacturers information. If
24、 plumbed-in body showers have two or more shower heads, the total water volume flow rate shall be at least 100 L/min; a minimum of (30 5) L/min thereof shall discharge over the head of the user. 4.2.2 Tank showers The water that is discharged by the tank shower shall be an overhead water volume flow
25、 rate out of the three classes according to Table 1. The tank shower shall be capable of delivering this supply for a minimum of 15 minutes. Flow pressure, max. deviation of water volume flow rate and the duration of water flow shall be specified by the manufacturer and shall be declared in the manu
26、facturers information (see clause 8). 4.2.3 Combination showers For combination showers the respective specified water volume flow rate shall be maintained during simultaneous actuation of both the body shower and the eye wash unit for at least 15 minutes. The emergency safety eye wash unit and its
27、water flow rate shall comply with DIN EN 15154-2. 4.3 Water distribution 4.3.1 Type test The water distribution of emergency body showers for production and logistic sites shall be measured by the following type test procedure. 4.3.2 Body showers of classes I and II At a distance 700 mm below the sh
28、ower head, (50 10) % of the volume of water delivered shall fall in a circle with a radius r of 200 mm (see Figure 1); the water level in the individual compartments of this circle shall not deviate by more than 30 % from the mean value. At this measuring level, the area reached by a minimum of 95 %
29、 of the water shall be limited to a circle with a radius r of 400 mm. The velocity of the water spray shall be low enough to be non-injurious to the user. NOTE All details of this type test procedure are in accordance with the test procedure for laboratory showers given in DIN EN 15154-1. 6 DIN 1289

35、iven to the avoidance of overheating through radiant heat or danger through refreezing. 5.2 Installation height The shower head shall be designed to be installed so that its lower edge is (2 200 100) mm above the level on which the user stands. On combination showers the integrated eye wash unit sha
36、ll conform to the installation height according to DIN EN 15154-2. 5.3 Free space The free space between the centre line of the shower head and the nearest obstruction (wall, vertical supply tube or similar) shall be a circle with a minimum radius r of 400 mm. Only the valve control element and/or t
37、he eyewash station and/or the hand held shower on a combination shower shall project into this space by a maximum of 200 mm. Other parts or components shall not project into this space. 6 Valves For manual operation, the valve shall be opened in a single operation by turning or moving a valve actuat
38、or to max. 90 or max. 200 mm stroke. The maximum force for the operation shall be 100 N or the maximum torque for operation 7 Nm. When applying this force/torque for a maximum of 1 s, the valve shall be fully open. A valve which is activated through a certain weight, e.g. by entering a platform, sha
39、ll be completely open at a load of maximal 40 kg in the centre of the platform (actuation). 8 DIN 12899-3:2009-04 9 In the case of automatic operation or actuation through a platform the shut-off valve shall also fully open within 1 s. The valve shall not close automatically once it has been opened,
40、 except for actuation platforms. The direction of operating the valve actuator shall be clearly visible and unmistakable. The valve actuator shall be large enough to be easily located and operated by the user even when wearing protective gloves with a maximum size in accordance with DIN EN 420. The
41、valve actuator shall be positioned between floor level and maximum 1 750 mm above that level. Actuation platforms shall have a minimum size of 500 mm 500 mm and shall be placed axially to the height of fall of the shower head. 7 Shower head Adjustments to the direction of spray or the water distribu
42、tion of a shower head shall only be possible using a tool. The shower head shall be self-draining between the valve and the outlet. The shower head shall be removable for maintenance but only by use of a tool. 8 Mechanical stability of tank showers Tank showers shall be built according to structural
43、 calculations given in DIN 1055-100 to ensure constructional stability. Where appropriate, wind loads according to DIN 1055-4 and snow loads according to DIN 1055-5 shall be considered. 9 Manufacturers information The manufacturer shall specify to which class according to this standard (see 4.1) the
44、 safety shower belongs. For safety showers with more than one shower head the total volume flow rate shall also be specified.
