28、 31 4.4.3 Duration of tests Replace the last sentence of the second paragraph with the following sentence: If the minimum operating current of the fuse is not reached in the test, the PROBE ASSEMBLY shall be operated for a period corresponding to the maximum fusing time or continuously for 1 h or 4
29、h, as specified above. 6 61010-031 Amend. 1 IEC:2008 Page 35 5.1.2 Identification In Table 1, replace row 7 with the following text: Number Symbol Reference Description 7 Not used Page 37 5.1.5 Parts protected by DOUBLE INSULATION or REINFORCED INSULATION Replace the existing title and text of the s

31、 fourth paragraph of 5.2, on page 39, replace the reference to “9.2“ by “9.1“. Page 41 5.4.3 Operation Add an item i), as follows: i) a warning that the measurement category of a combination of a PROBE ASSEMBLY and an accessory is the lower of the measurement categories of the PROBE ASSEMBLY and of
32、the accessory. Page 43 6.2 Determination of ACCESSIBLE parts Delete the reference “(see 6.4, note 1)”, at the end of the first paragraph. 61010-031 Amend. 1 IEC:2008 7 Page 49 6.3.1.3 Capacitance Add a new last paragraph, as follows: See Figure 5. Page 51 6.3.2.3 Capacitance Replace the title of Fig

Replace the existing conformity statement with the following new conformity s
34、tatement: Conformity is checked by inspection, and by the voltage tests of 6.6 (without humidity preconditioning), using metal foil tightly wrapped around a 150 mm 20 mm length of cable. Test voltage values are based on the CLEARANCES of the probe listed in Table 3 for measurement categories II, III
35、 or IV, and on the calculation of 6.5.2.2 for measurement category I or if no category is specified. 6.4.4 PROBE TIPS Replace the existing text of 6.4.4 with the following text, but retain Figure 6: PROBE TIPS that may be HAZARDOUS LIVE during NORMAL USE shall meet the following requirements (see 6.
36、1.1). If a conductive part of a PROBE TIP can become HAZARDOUS LIVE, a BARRIER shall be fitted to reduce the danger of touching an exposed conductive part of the PROBE TIP, and to provide an indication of the limit beyond which it may be hazardous to touch the probe body during use. CLEARANCES and C
37、REEPAGE DISTANCES between the HAZARDOUS LIVE part of the PROBE TIP and the hand-held side of the BARRIER shall be those specified for REINFORCED INSULATION. Figure 6a gives an example of PROBE ASSEMBLIES with BARRIERS and indicates applicable CLEARANCES and CREEPAGE DISTANCES. 8 61010-031 Amend. 1 I
38、EC:2008 Spring-loaded squeeze PROBE ASSEMBLIES RATED for WORKING VOLTAGES up to 1 kV (see Figure 6b) are acceptable without a BARRIER provided that: a) actuation of the spring-loaded mechanism prevents the OPERATOR touching a HAZARDOUS LIVE part; and b) the CLEARANCE and CREEPAGE DISTANCE between th
39、e PROBE TIP and the nearest surface which the OPERATOR needs to touch to actuate the mechanism is increased by an additional protective distance of 45 mm. Insulated crocodile and similar clips (see Figure 6c) RATED for measurement category I or II which require finger pressure at about 90 to the axi
40、s of the clip are acceptable without a BARRIER, provided that there is a tactile indicator to indicate the limit of safe access for the OPERATOR. NOTE See Clause 13 for additional requirements for the exposed conductive parts of PROBE TIPS. Conformity is checked by inspection and measurement. Page 6
41、1 6.5 CLEARANCES and CREEPAGE DISTANCES Replace, in the first line of the first paragraph, the reference to “6.5.4” by “6.5.3”. 6.5.1.1 CLEARANCES Replace, on page 63, in the second line of the fifth paragraph, the words “dielectric strength test” with the words “voltage test”.

42、ANCE values for measurement category I Replace the note with the following note: NOTE The following is an example: CLEARANCE for REINFORCED INSULATION for a peak WORKING VOLTAGE of 3 500 V and a maximum transient overvoltage of 4 500 V. UM= UW+ Ut= (3 500 + 4 500) V = 8 000 V F = (1,25 UW/ UM) 0,25
