The disconnection may be achieved by having the plug accessible or by

6、incorporating a switch in the fixed wiring in accordance with the wiring rules. 除非器具帶有一個符合24.3 的一個開關，否則其需有一個在安裝后用戶能進行插拔的插頭, 或者一個串聯(lián)在固定配線上的開關來斷開電源. Compliance is checked by inspection. 通過視檢,檢查其合格性。,安裝尺寸,Clause 8 Protection against access to live part,8.1 防止接觸到帶電體的要求, 通過8.1.1, 8.1.2, 8.1.3的測試工具檢查, 8.1.

7、4是對安全低電壓的判定. 8.1.5是對嵌入式,固定式器具的要求. 8.2 II類電器與II類結構的對基本絕緣的要求. 嵌入式與便攜式微波爐的要求一樣。,防觸電Clause 8.1.5,8.1.5 Live parts of built-in appliances, fixed appliances and appliances delivered in separate units, shall be protected at least by basic insulation before installation or assembly. Compliance is checked by

8、 inspection and by the test of 8.1.1. 嵌入式器具、固定式器具和以幾個分離組件形式交付的器具在安裝或裝配之前，其帶電部件至少應由基本絕緣來防護。 通過視檢，來檢查其合格性。,Clause 11 Heating,11.2 嵌入式微波爐對測試角有專門的要求, 要按照說明書的安裝要求來布置測試角. 11.3 溫升測試方法(電阻法,熱電偶法) 11.4 電熱器器具測試 11.5 電動類器具測試 11.6 復合類器具測試 11.7 測試時間確定 11.8 測試結果判定,測試角情況Clause 11.2,11.2 測試角要求 Built-in appliances ar

Slidin

12、g doors are positioned so that they are approximately two-thirds open. A force of 35 N is applied to the inside surface of a hinged door at a point 25 mm from its free edge or to the handle of a sliding door. 21.101 將鉸鏈門打開到全開位置前約30的位置，滑動門約打開2/3,然后將35 N的力加至鉸鏈門內表面離其自由端25 mm處的一點上或滑動門手柄處。,機械強度要求 Clause

13、21.101,the force is applied by means of a spring balance having a spring constant of 1,05 N/mm. It is initially applied with an opposing force applied to the other side of the door or handle. The opposing force is then removed to allow the door to complete its travel to the fully open position. The

14、test is carried out five times. 這 一外 力 是由一彈性系數(shù)為1.0 5N /mm的彈簧工具施加的，首先以反向的力加到門或手柄的另一側，然后去掉這一反向力使門完全打開。 試 驗 進 行五次。,Clause 21.101,The test is repeated on doors of stationary appliances and built-in appliances except that the door is initially placed midway between the fully open and closed positions; th

15、e applied force is 1,5 times the force required to open the door or 65 N, whichever is greater. However if the force cannot be measured or if the door is opened indirectly, the 65 N force is applied. The test is carried out five times. 在駐 立 式 微波爐和嵌裝式微波爐的門上重復試驗，但試驗條件改為： 門 的初始狀態(tài)置于全開和關閉的中間位置； 施 加的力是打開門

16、所需力的1.5倍或65 N，取其較大者，如果該力無法測量或門已間接地被打開，則用65N的力 試 驗 進 行五次(打開門),Clause 21.101,Doors are placed midway between the fully open and closed positions. A closing force of 90 N is applied to the outside surface of a hinged door at a point 25 mm from the free edge or to the handle of a sliding door, initially

17、 with the opposing force as described above. This test is carried out 10 times. The appliance shall then comply with Clause 32. 將 門 置 于全開和關閉的中間位置，用一個90N 的關門力施加在鉸鏈門外表面離自由端25m m處或加在滑動門的把手上，開始時是用上述的相反的力。 試 驗 進 行10次。(合上門) 器 具 應 符合第32章的要求。,Clause 22 Construction,Part I 通用部份(22.1-22.52) Part II 嵌入式除22.101
