Add 10 ml of distilled/de-ionized water to the evaporating basin and place this in the fume cupboard behind the safety screen. Whilst holding the test tube firmly with the test tube holder at an angle of 45° - 60° to the vertical, introduce a piece of freshly cut, clean sodium (about the size of a small pea) (200 mg – 250 mg) into the mouth of the test tube without allowing it to come into contact with the sample. With the safety screen in place, heat the sodium gently until it melts and runs down on to the sample (there may be a vigorous reaction when the molten sodium reaches the sample if halogens are present). Heat the tube gently for about 1 min, then more strongly until the lower 20 mm of the tube glows red hot. Plunge the red hot tube into the water in the evaporating basin, immediately placing the gauze on top. (The gauze prevents any loss of material when the tube shatters on contact with the water.) Allow any non reacted sodium to react before grinding up the solution and glass. Filter, and separate the filtrate into two equal portions.C.3.2 Chlorine and bromineTo the first portion of the filtrate, add sufficient nitric acid to make the solution acidic. Boil this solution until its total volume has been reduced by half (this is to remove any HCN or H2S, if present, which would interfere with the test). Add 1 ml silver nitrate solution; a white or yellowish-white precipitate indicates the presence of halogen (Cl, Br) in the original sample. (If the liquor is decanted, and the precipitate is white and readily soluble in dilute ammonia, then chloride is present.)C.3.3 FluorineTo the second portion of the filtrate, acidify with glacial acetic acid. Boil this solution until its total volume has been reduced by half. Add 2 to 3 drops freshly prepared zirconium lake reagent (equal volumes of: a) Alizarin solution: 0,05 g Alizarin Red-S in 50 ml distilled water, b) Zirconium solution: 0,05 g zirconium nitrate in 10 ml concentrated HCl diluted with 50 ml distilled water). Heat at 40 °C for 1 h. The presence of fluoride is indicated by the red/pink colouration being bleached to yellow.Test of long term resistance of insulation to D.C.A test sample with a length of minimum 5m shall be immersed into water containing 3 % NaCl. Further on minimum 300mm of the sample shall stick out of the water. The water-bath shall be retained for (240 ± 2) h at a high temperature of (85 ± 2) °C and a D.C.-voltage 0,9kV shall be applied between conductor and water whereby the conductor shall be connected to the positive potential.The current of this circuit shall be measured with a period of not more than 24h. If possible a continuous measurement shall be preferred.The measured values shall be recorded in a time-current-curve which identifies a stable progress.NOTE A stable progress is e.g. an increase of less than 10% of leakage current on the average for a time of 24h (This is part of the inspection based on practical experiences)After storing the samples shall be taken out of the salt-water-solution and a voltage test according to Ref.-No. 1.2 of table 1 shall be performed. The test voltage shall be the rated voltage (U) of the cable.Cold impact testThe cold impact test shall be performed at –40°C according to clause 8.5 of EN 60811-1-4, but the mass of hammer, the mass of test probe and the height shall comply with table 2.Table E.1 – Parameter for cold impact testDiameter of cable (D) Mass of hammer Mass of test probe height mm g g mmD < 15 1 000 200 10015 < D≤ 25 1 500 200 150D > 25 2 000 200 200The inner and outer surface of sheath shall be inspected with normal or corrective visual faculty without magnification. Only the outer surface of the insulation shall be inspected. No cracks must be determinedAnnex F(normative)Dynamic penetration testA test apparatus for pull test (or a equivalent apparatus) shall be operated in pressure modus and shall be equipped with a measuring device which is able to record the force of penetration of the spring-steel-needle (see figure F.1b) through the insulation or sheath of a completed cable. A circuit with low voltage which finish the test at the moment when the needle penetrates the insulation or the sheath and makes contact with the conductor shall be added.The test shall be performed at room temperature. The force applying to the needle shall be increased continuously with 1 N/s until contact with the conductor has been made. 4 tests at each sample shall be performed and the force at the moment of contact shall be recorded. After each test the sample shall be moved forward and shall be turned clockwise for 90°.The mean value of the 4 test results must not be less than the minimum value F determined with following formulaF = 50 ⋅DD diameter of cable in mmDimensions in mma) detail X(edges not broken or rounded, without ridge)b) detail YCaption 1 N.A. 2 N.A. 3 Load 4 Clamp 5 Sample6Mounting surface7 Fixing screw 8 Blade9 Shoulder with sufficient depth for testing the insulation 10 Needle of spring steel 11SampleFigure F.1 – Arrangement for penetration testAnnex G(normative)Notch propagationThree samples of the cable shall be notched, to a depth of 0,05 mm of the insulation or sheathing, at four points equally spaced with respect to one another around the circumference and 25 mm apart along the length, and in a plane mutually perpendicular to the conductor.One of the samples shall be conditioned at -15 °C, one at ambient temperature and one at 85 °C, in all cases for 3 h, after which time they shall be wound on to a mandrel, (3 ± 0,3) times the minimum specified diameter of the cable, whilst at the conditioning temperature. The notched sample shall be wrapped around the mandrel such that at least one notch is on the outside of the cable.The sample shall be allowed to return to ambient temperature and then subjected to the voltage test given in no. 1.2 of Table 1 but at half the rated voltage U0.。

IEC 61215是太阳能光电（PV）电池模组的设计和性能的标准，并测试光伏组件在各种条件下的耐久性和可靠性。
IEC 61730则是关于光伏组件的安全性标准，要求在电气、机械和防火方面具备符合要求的性能。
第三步：准备认证申请材料准备认证申请材料是获得TUV认证的重要步骤。
申请材料通常需要包括光伏组件的技术规范、性能数据、电气和机械安全测试报告等。
此外，还需要提供光伏组件制造商的质量管理体系文件，例如ISO 9001认证等。
第四步：组织认证测试认证测试是获得TUV认证的关键步骤之一。
认证测试通常由认证机构的工程师进行，包括性能测试、电气测试、机械测试和安全测试等。
性能测试检查光伏组件的功率输出、温度特性和光正比特性等。
电气测试检查光伏组件的电气参数，例如最大功率点和开路电压等。
机械测试和安全测试则包括抗风压、防火性能和机械强度等。
第五步：评估认证结果认证测试完成后，认证机构将评估测试结果，并判断光伏组件是否符合TUV认证标准。
如果通过评估，认证机构将颁发TUV认证证书，确认光伏组件的质量、安全性和可靠性。
