44 Introduction
45 The objective of the EN 50483 series is to provide a method of testing the suitability of accessories when used
46 under normal operating conditions with low voltage aerial bundled cables (ABC) complying with HD 626.
47 Climate differs across Europe and in order to meet the differing geographic climatic conditions it is necessary
48 to provide a range of tests to meet these variations. A range of optional, additional tests is provided to meet
49 the varying climatic needs and these should be agreed between the customer and the manufacturer and/or
50 the supplier (see Annex C).
51 This European Standard does not invalidate existing approvals of products achieved on the basis of national
52 standards and specifications and/or the demonstration of satisfactory service performance. However, products
53 approved according to such national standards or specifications cannot directly claim approval to this
54 European Standard. It may be possible, subject to agreement between the customer and the manufacturer
55 and/or the supplier, and/or the relevant conformity assessment body, to demonstrate that conformity to the
56 earlier standard can be used to claim conformity to this standard, provided an assessment is made of any
57 additional type testing that may need to be carried out. Any such additional testing that is part of a sequence
58 of testing cannot be done separately.

158 6.4.3.2 Gas atmosphere test (Method 1)
159 6.4.3.2.1 Principle
160 This test exposes samples to a humidity-saturated atmosphere rich with sulphur dioxide (initial concentration
161 SO : 0,066 7 % (667 parts per million by volume)) with defined conditions of temperature and pressure.
162 6.4.3.2.2 Test equipment
163 The samples and supports shall be installed in a hermetic test chamber, with a humidity-saturated atmosphere
164 in the presence of sulphur dioxide.
165 This test chamber shall be made of inert material. The test shall be made in accordance with EN ISO 22479.
166 6.4.3.2.3 Preparation of SO atmosphere
167 After closing the chamber, sulphur dioxide (concentration = 0,066 7 %) shall be introduced from either a gas
168 bottle or using a specific reaction in the chamber as described in Annex B.
169 6.4.3.2.4 Procedure
170 Each period, or basic module, shall comprise a weekly sequence.
171 7 cycles of 24 h (168 h total), each cycle includes an 8 h exposure with saturated humidity and high sulphur
172 dioxide atmosphere (a total exposure of 56 h), and a 16 h exposure at the laboratory atmosphere (a total
173 exposure of 112 h).
174 NOTE Exposure to laboratory atmosphere can be achieved by opening the chamber door. It is the intention of this
175 phase to allow clean air to circulate around the test samples.
176 During the 8 h period, the temperature is raised to (40 ± 3) °C. During the 16 h period the chamber remains at
177 ambient temperature and finally the water and sulphur dioxide atmosphere is renewed to the concentration as
178 specified in 6.4.3.2.3.
179 6.4.3.2.5 Cleaning
180 When the specimens are exposed successively to a neutral salt spray and then to a humidity saturated
181 atmosphere with sulphur dioxide, the procedure shall be
182 — 7 cycles of 24 h in salt,
183 — no cleaning,
184 — 7 cycles of 24 h in sulphur dioxide,
185 — cleaning in accordance with 6.3.
186 6.4.3.3 Gas atmosphere test (Method 2)
187 6.4.3.3.1 Procedure
188 The test samples shall be subjected to a cyclic corrosion test consisting of 1 h period of drying and 1 h period
189 of fog. The test shall consist of 500 cycles (1 000 h). The fog period shall be at ambient temperature, while the
190 drying time shall be at a higher temperature.
191 NOTE Experience indicates that longer cycle times can produce slower degradation.
192 6.4.3.3.2 Test equipment
193 The apparatus for salt spray (fog) testing consists of a fog chamber, a salt solution reservoir, a supply of
194 suitable conditioned compressed air, one or more atomising nozzles, specimen supports, provision for heating
oSIST prEN 50483-6:2024
prEN 50483-6:2024 (E)
195 the chamber, and necessary means of control. The size and detailed construction of the cabinet are optional,
196 provided the conditions obtained meet the requirements of this standard. The material of construction shall be
197 such that it will not be affected by the corrosiveness of the fog. The chamber shall be designed so that drops
198 of solution that accumulate on the ceiling or cover of the chamber do not fall on the specimen being tested.
199 The nozzle or nozzles shall be directed so that none of the spray can impinge directly on the test specimen.
200 The solution shall not be recycled.
201 6.4.3.3.3 Atomisation and quantity of fog
202 At least two clean fog collectors shall be placed within the exposure zone so that drops of solution from the
203 test specimen or any other source are not collected. The collectors shall be positioned in the proximity of the
204 specimens, one near to a nozzle and the other, as far as possible from all nozzles. It shall be secured so that,
205 for each 80 cm of horizontal collecting area, fog accumulates in each collector at a rate between 1,0 ml to
206 2,0 ml of solution per hour, based on an average run of at least 16 h continuous spray.
207 NOTE Suitable collecting devices are glass funnels with the stems inserted through stoppers into graduated cylinders
208 or crystallizing dishes. Funnels and dishes with a diameter of 100 mm have an area of about 80 cm .
209 6.4.3.3.4 Salt solution
210 The salt solution shall consist of 0,05 % sodium chloride (NaCl) and 0,35 % ammonium sulphate (NH ) (SO )
4 2 4
211 by mass. The water shall be distilled or de-ionized water. The sodium chloride shall be substantially free of
212 nickel and copper and shall contain, on the dry basis, not more than 0,1 % of sodium iodide and not more than
213 0,3 % of total impurities. The ammonium sulphate shall contain not more than 0,3 % total impurities. Some
214 salts contain additives that may act as corrosion inhibitors; careful attention shall be given to the chemical
215 content of the salt.
216 The pH of the collected solution shall be between 5,0 and 5,4.
217 6.4.3.3.5 Air supply
218 The compressed air supply to the nozzle or nozzles, for atomising the salt solution, shall be free of oil and dirt
219 and maintain the air supply between 70 kPa and 170 kPa.
220 6.4.3.3.6 Procedure
221 The test shall consist of cycles of a 1 h drying period and a 1 h fog period. The electrolyte shall be a solution
222 of sodium chloride and ammonium sulphate. The fog period shall be performed at ambient temperature, while
223 the drying-off shall be at higher temperature. The solution atomising air shall not be saturated with water.
224 During the fog period, no heating shall be applied to the cabinet. The fog exposure shall be at (24 ± 3) °C.
225 During the drying-off period the temperature throughout the exposure zone shall reach and remain at
226 (35 ± 2) °C within 45 min of switching from the fog period to the dry period. The drying-off shall be achieved by
227 purging the chamber with fresh air so that within 45 min all visible moisture shall be dried off the specimen.
228 Humidified air shall not be used for drying.
229 NOTE As the specimen cycles from wet to dry it is subjected to a range of solution concentration varying from dilute
230 during the fog period to very concentrated just before the water dries off completely.
231 6.4.3.3.7 Cleaning
232 There shall be no cleaning of the test samples between the test cycles.
233 At completion of the test the samples shall be cleaned in accordance with 6.3.

240 6.4.4.2.1 Principle
241 For saline polluted areas an optional additional test shall be carried out when this is agreed between the
242 customer and the manufacturer and/or the supplier. In order to minimize testing, when agreed, this test shall
243 be carried out during the mandatory heat cycle tests as provided in prEN 50483-5.
244 6.4.4.2.2 Test arrangement
245 This shall be, generally, in accordance with prEN 50483-5:2024, 5.2 but in particular the test circuit, as
246 described in prEN 50483-5:2024, 5.2.1, shall be modified to allow the samples to be fully immersed in a saline
247 solution during the heat cycle.
248 The saline solution shall be maintained at 29,22 g/l (approximately 3 % of mass) concentration of NaCl
249 throughout the test.
250 NOTE A practical arrangement is to place the test samples in a tank and pump the saline solution from a reservoir
251 below. The tank can then be drained back into the reservoir after the required immersion period.
252 The test loop may be arranged so that the samples, but not the measurement points, are immersed in the
253 saline solution. Figure 1 shows a typical arrangement.
