BS EN 50131-8:2009 13 EN 50131-8:2009 Annex A (normative) Performance tests This annex states the test procedure for evaluating fog outp
36、ut and fog performance. NOTE Since it is accepted that there is a direct relationship between the concentration of airborne fog chemical and visibility through the resulting fog, this has been selected as the most appropriate basis of quantifying fog output/performance of the EUT (Equipment Under Te
37、st). The following tests should be carried out in a fog test chamber as detailed below. A.1 Fog test chamber The fog test chamber shall be set up as detailed in Figure A.1. The fog test chamber shall be, apart from as otherwise detailed in this document, an empty and windowless room or enclosure of
38、volume (150 - 200) m, with a height to ceiling of (2,5 - 3) m. The volume of the test chamber shall be recorded as (v). The ratio of length to width shall be between 1:1 and 2:1. The chamber shall be well lit (300 lx - 500 lx measured at 76 cm above the floor of the chamber). Four distribution fans
39、(as shown in Figure A.1) shall be mounted as the same level in the machine equal distance between the security fog system and the corner of the room as indicated with the flow rate to give a homogenous distribution in the room. The fans shall be rated with a flow rate of between (0,15 - 0,3) m/s and
40、 the maximum fan tip speed shall not exceed 3 m/s. NOTE The distribution fans are only used to calculate the amount of fog chemical used. The staggered black cross markers (as per Figure A.2) shall be positioned at the observers/operators eye level, at 2 m and 3 m from the viewing position of the ob
41、server. The staggered grey/black marker (as per Figure A.3) shall be positioned at the observers/operators eye level, at 1 m from the viewing position of the observer. The chamber shall be at (20 - 22) C, with a relative humidity of (40 - 75) %. The EUT shall be placed centrally within the chamber,
42、so that the output nozzle is 1 m above floor level. If the EUT has multiple output nozzles, the centre of the group of nozzles shall be at 1 m above floor level. The EUT shall be mounted on a calibrated digital weighing scale, measuring in single gram increments. All necessary supply leads to the EU
43、T shall be supported in such a way as to nullify their impact on the calculation of the amount of fog chemical used. BS EN 50131-8:2009EN 50131-8:2009 14 A.2 Test procedure Determination of fog chemical concentration to achieve 1 m visibility (1 OD/m, 90 % obscuration) that is essentially a measure
44、of the efficiency of the fog. The purpose of the first part of the test is to determine the amount of fog chemical required by the EUT to achieve a uniform 1 m visibility through the fog in the test chamber. For each activation of the EUT the weight of chemical used per activation shall be recorded.
45、 For the sake of accuracy, and if the manufacturer of the EUT agrees, the flow rate through the EUT may be reduced so that the visibility target is achieved more progressively, since the purpose of this exercise is to determine the consumption of fog chemical (mg/m) to achieve 1 m visibility, not to
46、 equate fog output. Alternatively, the manufacturer of the EUT may elect to produce smoke in short bursts to achieve the same result. The distribution fans shall be switched on within the chamber to ensure even fog distribution is achieved once the EUT is activated. The observer/operator within the
47、chamber shall activate the EUT. The observer/operator within the test room shall stop the EUT when the black element of the 1 m marker is not visible, and the weight of fog chemical used to achieve that visibility noted. The test chamber shall then be cleared of fog and this procedure shall be repea
48、ted 2 times, and the mean average weight (zi) of fog chemical used calculated. A.3 Activation test The purpose of this part of the test is to enable specific performance figures to be attributed to individual EUTs. The test chamber shall be clear of all visible fog. Distribution fans shall not be us
49、ed in this test. From start time (t0) the observer/operator shall activate the EUT until the weight of fog chemical used is as in A.2. Record this time as (t1). The observer/operator shall then assume his viewing position. Two minutes after (t1), the observer/operator shall confirm that the greyscale element of the 1 m marker is not visible. It is accepted that the black element of the 1 m marker may just be visible. If the greyscale element of the 1 m marker is visi
