Accessories and surface-type mounting boxes shall be resistant to heat. 
插接裝置及明裝安裝盒必須能夠耐熱。 
Compliance is checked as shown in Table 24 (2006-05 amended) 
依表 24 進行測試。(2006-05  修訂) 
Parts intended for decorative purposes, such as certain lids, are not submitted to any of these tests. 
僅作裝飾用的零件如某些蓋子，不做本條文試驗。 
25.1 The specimens are kept for 1 h in a heating cabinet at a temperature of (100  ± 2) . ℃  
將試樣放進溫度為 100±2℃的烘箱裡 1 小時。 
During the test, they shall not undergo any change impairing their further use and sealing compound, if any, shall not flow to such an extent that live parts are exposed. 
試驗期間，試樣不得出現影響後續使用的變化。而且，如果有密封膠的話，密封膠不得大量流失以至露出帶電部件。 
After the test, the specimens are then allowed to cool down to approximately room temperature. There shall be no access to live parts which are normally not accessible when the specimens are mounted as in normal use, even if the probe B of IEC 61032 is applied with a force not exceeding 5 N. 
試驗結束後，使試樣冷卻到大約室溫。當插接裝置按正常使用安裝好後，即使用 IEC 61032
探棒 B 的標準測試指施加不大於 5N 的力時，測試指不應觸及通常是不可觸及的帶電部件。  
After the test, markings shall still be legible. 
試驗結束後，標誌仍應清晰可辨。 
Discoloration, blisters or slight displacement of the sealing compound is disregarded, provided that safety is not impaired within the meaning of this standard. 
只要不損害本標準意義上的安全，則密封膠的褪色、起泡或輕度流失均可忽略不計。 
25.2 Parts of insulating material necessary to retain current-carrying parts and parts of the earthing circuit in position, as well as parts of the front surface zone of thermoplastic material, 2 mm wide, surrounding the phase and neutral pin entry holes of socket-outlets, shall be subjected to a ball-pressure test by means of the apparatus shown in figure 37, except that the insulating parts necessary to retain the earthing terminals in position in a box shall be tested as specified in 25.3. 
用以將載流部件和接地電路銅片保持在正常位置所必需的絕緣材料部件，以及插座火線及中線插孔周遭 2mm寬度由熱塑性材料製成部件，要使用圖 37 所示設備做球壓試驗，但安裝盒裡用以將接地端子保持在正常位置所必需的絕緣部件，要按 25.3 條的規定做試驗。 
NOTE When it is not possible to carry out the test on the specimens, the test should be carried out on a piece at least 2 mm thick which is cut from the specimen. If this is not possible, no more than four layers, each cut from the same specimen, may be used, in which case the total thickness of the layers shall be not less than 2,5 mm. 
注︰如果不可能在受試試樣上做試驗，則應從試樣上割下至少 2 mm厚的小塊試樣做試驗。如果這樣做仍不可行，則可以用不多於 4 層、每層均是從試樣上割下的試件來做試驗。這些試件的總厚度不得小於 2.5mm。 
The part under test shall be placed on a steel plate at least 3 mm thick and in direct contact with it. 
將試樣部件放置在至少 3mm厚的鋼板上，使之與鋼板直接接觸。 
The surface of the part to be tested is placed in the horizontal position and the hemispherical tip of the test equipment is pressed against the surface with a force of 20 N. 
將被試部件的表面置於水平位置，並用 20N的力將一直徑為 5mm的鋼球壓住該表面。 
The test load and the supporting means shall be placed within the heating cabinet for a sufficient 
time to ensure that they have attained the stabilized testing temperature before the test 
commences. The test is made in a heating cabinet at a temperature of (125  ± 2) . ℃  
將試驗負載和支承裝置放在烘箱內足夠長的時間，以確保試驗開始之前負載和支承裝置已
經達到穩定的試驗溫度。試驗要在 125±2℃的烘箱內進行。 
After 1 h the ball shall be removed from the specimen, which is then immersed within 10 s, in cold 
water for cooling down to approximately room temperature. 
1 小時之後，將球從試樣上卸下並將試樣浸入冷水以便它在 10s 之內冷卻至大約室溫。 
The diameter of the impression caused by the ball is measured and shall not exceed 2 mm. 
量測鋼球壓痕的直徑，此直徑不得超過 2mm。 
25.3 Parts of insulating material not necessary to retain current-carrying parts and parts of the earthing circuit in position, even though they are in contact with them, are subjected to a ball-pressure test in accordance with 25.2, but the test is made at a temperature of (70  ± 2) , ℃  or (40  ± 2)  plus the  ℃ highest temperature rise determined for the relevant part during the test of clause 19, whichever is the higher. 
雖然與載流都件和接地電路部件接觸，但不是將他們保持在正常位置所必需的絕緣材料部件，應按 25.2 條的規定進行球壓試驗，但試驗要在 70±2℃下進行，或 40±2℃加上第 l9 章的試驗期間在有關部件測得的最高溫昇下進行，取二者中較高的溫度。 
25.4 The specimens are subjected to a compression test by means of an apparatus as shown in figure 38, the test being made in a heating cabinet at a temperature of (80  ± 2) . ℃  
用圖 38 所示的試驗裝置在 80±2℃的烘箱內對試樣進行高溫壓力試驗。 
The apparatus comprises two steel jaws, having a cylindrical face of 25 mm radius, a width of 15 mm and a length of 50 mm. The length of 50 mm can be increased, depending on the size of the accessory to be tested. 
試驗裝置由兩塊鋼夾塊組成，夾塊具有一個半徑為 25mm的圓柱形表面，寬度為 15mm，長度至少 50 mm。 
The corners are rounded with a radius of 2,5 mm. 
稜角應加工成半徑為 2.5mm的圓角。. 
The specimen is clamped between the jaws in such a way that these press against it in the area where it is gripped in normal use, the centre line of the jaws coinciding as nearly as possible with the centre of this area. The force applied through the jaws is 20 N. 
將試樣夾在夾塊之間，使夾塊壓在正常使用時所抓的部位上，夾塊的中心線應盡量與該部位的中心重合，透過夾塊施加 20N 的力。 
After 1 h, the jaws are removed and the specimens shall show no damage within the meaning of this standard. 
1 小時之後，卸下夾塊，試樣不得出現本標準意義上的損壞。
