The measuring points shall be posit
26、ioned appropriately for the type of measurement being carried out. For aquatic fireworks, a water test area shall be available for testing the resistance to moisture and functioning in the expected manner. 4.2 Wind measurement The wind speed at a height of 1,50 m above the ground shall be measured a
27、nd recorded using a wind speed meter (see 5.5). No performance testing shall be carried out if the wind speed exceeds 5,0 m/s. 5 Apparatus Any equivalent apparatus with the same accuracy or better may be used. 5.1 Timing device.

29、ed meter should accurate to at least 0,5 m/s. 5.6 Balance. Balance, with an accuracy of 0,01 g or better. 5.7 Temperature chamber. 5.7.1 Up to (50 2,5) C. 5.7.2 Up to (75 2,5) C. 5.8 Sound level meter. Sound level meter of class 1 conform to EN 61672-1 with a free-field microphone. 5.9 Shock apparat
30、us. The apparatus shall provide a deceleration of 490 m/s2(-50/+100) m/s2(when measured at the centre of an unloaded platform) and the shock impulse duration (time elapsed from the starting of the machines deceleration to the time in which the deceleration reaches its maximum value during each first
31、 shock pulse) shall be 2 ms 1 ms working at a frequency of 1 Hz 0,1 Hz. An example of an apparatus is shown in Annex A. 5.10 Devices for measuring heights. Heights shall be measured using universal surveying instruments (USI) such as theodolites, electronic spirit levels or video (visible and/or inf
32、rared) systems. Examples of measuring methods and the calculation of the height are given in Annex B. 5.11 Goniometer. Goniometer reading to 1 or better. 5.12 Mortar. The rising height of shells depends particularly on the clearance of the shell in the mortar (ratio of the maximum cross section area
33、 of the shell (AShell) to the inner cross section area of the mortar (Amortar), also designated as “Q“. Q is the ratio of the outer diameter of the shell (do,shell,including the fuse to the lifting charge) squared over the inner diameter of the mortar (di,mortar) squared. The outer diameter of the s
34、hell shall be measured horizontally at the place of largest diameter including the fuse to the lifting charge. The following conditions shall be achieved: 98,09,0mortari,2shello,2mortarshell=ddAAQ BS EN 16261-3:2012EN 16261-3:2012 (E) 7 shello,2mortari,shello,21,102,1 ddd For calibre 100 mm, a wider
35、 tolerance can be accepted. The following conditions shall be achieved: 98,083,0*100Q shello,2mortari,*shello,22,1(02,1 ddd Another determining factor influencing the rising height is the length of the mortar (lmortar) length from the mortar muzzle to the mortar ground. The dimensions of the mortar
36、may also be determined from Figures 1, 2 and 3.

39、outer dimensions of the tested article to the nearest of 1,0 mm and record the results. BS EN 16261-3:2012EN 16261-3:2012 (E) 10 6.1.2 Determination of calibre 6.1.2.1 Apparatus Calliper (see 5.2). 6.1.2.2 Procedure Use the calliper (see 5.2) to measure the calibre of the tested article at least thr
40、ee times at different positions on the article and to the nearest of 0,1 mm and record the results. 6.1.3 Determination of gross mass Use the balance (see 5.6) to measure the gross mass of the tested article and record the results. 6.2 Design Verification Compare the actual article with the detailed
41、 manufacturers drawing. Observe and record any nonconformity. 6.3 Determination of tube angle 6.3.1 Apparatus Goniometer (see 5.11). 6.3.2 Procedure For determination of the tube angle, dismantle the functioned article (if necessary) in such a way that the angle of the tube against the vertical can
42、be measured with goniometer (see Figure 4) and record the results.

43、 (firing device at 90 2). The measurement of heights may be made according to one of the methods described in Annex B. 6.4.2 Dimensions of mortar For type and batch tests, defined standard mortars (5.12) shall be used. Tables for the standardised inside diameter and inside length are given in 5.12.
44、When the height of a shell casing (excluding the lifting charge) is more than twice the calibre, for all shells with a calibre greater than 400 mm and for shells that are designed to be fired from a specific mortar, the mortar recommended by the manufacturer shall be used. 6.4.3 Support of mortar Th
45、e mortar shall be supported in such a way that it is not displaced by the firing of the tested article. No deformable material shall be placed under the mortar. 6.5 Measurement of sound pressure level 6.5.1 Apparatus Sound level meter (see 5.8); Measuring tape (see 5.4). 6.5.2 Procedure Set up the m

The distance between the measuring and firing point may be the same as for the measuring of the Rising Height according to 6.4. Place and ignite the tes
47、t sample in accordance with the labelled instructions and instructions for use, and record the maximum A-weighted impulse sound pressure levels as measured by the sound level meter (see 5.8) and the distance from the firing point (see 5.4). NOTE An example of the calculation method for safety/protec
