The measuring points shall be positioned appropriately for the type of measurement being carried out. For aqu
30、atic 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 and recorded using a wind speed meter (see 5.5). No performance testing sha
31、ll 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.

32、SO 3599. 5.3 Ruler. Ruler, with a scale resolution of 1,0 mm or better. DIN EN 16261-3:2013-03 EN 16261-3:2012 (E) 6 5.4 Measuring tape. Measuring tape, with a scale resolution of 10 mm or better. 5.5 Wind speed meter. The wind speed meter should accurate to at least 0,5 m/s. 5.6 Balance. Balance, w
33、ith 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 apparatus. The apparatus shall provide a deceleration of 490 m/s2(-50/+100)
34、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 shock pulse) shall be 2 ms 1 ms working at a frequency of 1 Hz 0,1 H
35、z. 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 infrared) systems. Examples of measuring methods and the calculation of
36、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 of the shell (AShell) to the inner cross section area of the mortar
37、(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 shell shall be measured horizontally at the place of largest diameter
38、including the fuse to the lifting charge. The following conditions shall be achieved: 98,09,0mortari,2shello,2mortarshell=ddAAQ DIN EN 16261-3:2013-03 EN 16261-3:2012 (E) 7 shello,2mortari,shello,21,102,1 ddd For calibre 100 mm, a wider tolerance can be accepted. The following conditions shall be ac
39、hieved: 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 may also be determined from Figures 1, 2 and 3. Key X calibre of

43、of 1,0 mm and record the results. DIN EN 16261-3:2013-03 EN 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 three times at different positions on the article an
44、d 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 manufacturers drawing. Observe and record any no
45、nconformity. 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 be measured with goniometer (see Figure 4) and re
46、cord the results.

The measurement of
47、 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. When the height of a shell casing (excluding
48、 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 The 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 so
