EN 16261-3:2012 (E) 5 1 Scope This European Standard specifies test methods for fireworks of category 4. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. EN 16261-1:2012, Pyrotechnic articles — Fireworks, Category 4 — Part 1: Terminology EN 16261-2:2013, Pyrotechnic articles — Fireworks, Category 4 — Part 2: Requirements EN 61672-1, Electroacoustics — Sound level meters — Part 1: Specifications (IEC 61672-1) ISO 3599, Vernier callipers reading to 0,1 and 0,05 mm 3 Terms and definitions For the purposes of this document, the terms and definitions given in EN 16261-1:2012 apply. 4 Test environment for functioning test 4.1 General A large unobstructed area, which shall be wide open. The measuring points shall be positioned 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 and 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. Timing device, capable of being read to the nearest 0,1 s. 5.2 Calliper. Calliper, flat faced vernier calliper reading to 0,1 mm, conforming to ISO 3599. 5.3 Ruler. Ruler, with a scale resolution of 1,0 mm or better. SIST EN 16261-3:2013

±= 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) m/s2 (when measured at the centre of an unloaded platform) and the shock impulse duration (time elapsed from the starting of the machine's 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 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 infrared) 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 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 shell 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 SIST EN 16261-3:2013

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 be measured with goniometer (see Figure 4) and record the results.

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. 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 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 plac
