試驗探針/UL試驗探針/UL1278 Bar probe

用于測試電器產品的結構和外殼是否有良好防觸電保護,以保證使用時不與帶電部件發生意外接觸。

產品概述:符合UL1278圖10.2標準要求。UL1278 Figure 10.2? Bar probe
?10.1.3 The acceptability of a guard is judged with respect to its general serviceability and with respect to  
the shape and size or both of the openings in it, in conjunction with the distance of the guard from the  
heating element and the other high-temperature parts mentioned in 10.1.1. Except as noted in 10.1.5, an  
opening in a guard is considered to be acceptable if, with the heater in any intended operating position,  
the following conditions are met:  
b) The shape and size of an opening which permits the vertically downward entrance of a bar  
probe 1/2 inch (12.7 mm) wide and 1/16 inch (1.6 mm) thick, see Figure 10.2, are such that a  
******** probe 1/16 inch thick and in the form of an isosceles ******** having a base of 2-3/4  
inches and an altitude of 5-1/2 inches, see Figure 10.3, is prevented from touching the heating  
element and the other high-temperature parts when the ******** probe is inserted, apex first, in  
any manner. The testing of an opening with the ******** probe applies also where the vertically  
downward insertion of the bar is prevented by the construction of the guard, the use of an  
additional barrier, or both, unless the vertically applied bar tends to be deflected outward – that  
is, away from the guard.
